0086<figref idref="DRAWINGS">FIG. 8</figref> is a disassembled front view and a plane cross-sectional view showing the configuration of a means for sensing mount of a protection cover according to still another embodiment of the present invention; and <figref idref="DRAWINGS">FIGS. 9 and 10</figref> are disassembled front views showing the configuration of a means for sensing opening and closing of a protection cover according to still another embodiment of the present invention.

0087First, the basic configuration of the protection cover for a mobile device according to an embodiment of the present invention will be described below in detail.

0088As the most outstanding characteristic of the configuration, as shown in <figref idref="DRAWINGS">FIGS. 1 to 3</figref>, a protection cover <b>10</b> for a mobile device according to the present invention includes a transparent section <b>20</b> capable of confirming key information F displayed on the display screen P when the mobile device M operates while the protection cover <b>10</b> is closed.

0089In this embodiment, the protection cover <b>10</b> may be formed in the shape of a sheet of plate made of a synthetic resin material or configured as an assembly of a fabric capable of high frequency fusion and a reinforcement member <b>60</b> assembled between the fabrics in one piece.

0090Apparently, a fabric capable of high frequency fusion such as soft velvet or suede may be patched on the entire inner surface of the protection cover <b>10</b> in order to protect the display screen P.

0091In addition, the key information F shown on the display screen P of the mobile device is information that can be confirmed through the transparent section without opening the protection cover <b>10</b> by briefly displaying only icons or the like of, for example, a character message, indication of remaining battery and the like, in addition to current date and time and a received phone number, among the content displayed on the display screen P.

0092For example, the key information F mostly means display of brief key information F such as current date and time, records of missed calls, the number of received character messages, indication of remaining battery, details of a received mail and the like.

0093Accordingly, a user may conveniently confirm the key information F displayed in the area of the transparent section <b>20</b> of the display screen P through the transparent section <b>20</b> without opening the protection cover <b>10</b>.

0094According to another embodiment of the present invention, the transparent section <b>20</b> is preferably formed at a position corresponding to the area on the display screen P where the key information F is displayed when the mobile device M operates.

0095In addition, the transparent section <b>20</b> is formed by penetrating a portion of the front surface of the protection cover <b>10</b> so that an opening section <b>11</b> may be formed in a size corresponding to the area displaying the key information F of the display screen.

0096When the mobile device operates, i.e., when a character message or a missed call is received, while the protection cover <b>10</b> covers the display screen P, the transparent section <b>20</b> configured in the form of an opening allows a user to confirm the character message or the missed call while the protection cover <b>10</b> is not opened. In addition, the user may conveniently confirm the date and time, remaining battery or the like by pushing a power button or a home button while the protection cover <b>10</b> is not opened.

0097Accordingly, the user is provided with convenience of confirming and handling the key information F displayed on the display screen by touching the display screen through the opening section <b>11</b> of the protection cover <b>10</b> without opening the protection cover <b>10</b>.

0098In addition, according to another embodiment of the present invention, as shown in <figref idref="DRAWINGS">FIGS. 1</figref><i>a </i>and <b>1</b><i>b</i>, the transparent section <b>20</b> has the opening section <b>11</b> formed at a portion of the front surface of the protection cover <b>10</b>, and the most outstanding characteristic configuration of the present invention is to further provide a transparent member <b>21</b> in the opening section <b>11</b> to protect the display screen P.

0099As described above, if the transparent section <b>20</b> is configured in the form of the opening section <b>11</b>, a shock or a scratch may be generated on the surface of the display screen P since the display screen P is exposed through the transparent section <b>20</b>.

0100In this embodiment, the transparent member <b>21</b> is further provided in the opening section <b>11</b> in order to prevent this problem.

0101According to still another embodiment of the present invention, as shown in <figref idref="DRAWINGS">FIG. 1</figref><i>a </i>or <b>2</b><i>a</i>, when the opening section <b>11</b> is formed in, for example, a rectangular shape, the transparent member <b>21</b> is also formed in a rectangular shape in correspondence with the shape of the opening section <b>11</b>.

0102Preferably, the transparent member <b>21</b> is formed in one piece together with the protection cover <b>10</b> to form a plane surface and has a transparent screen section <b>22</b> exposed outside, and a fixing unit <b>23</b> inserted into and assembled with the protection cover <b>10</b> is provided along the edges of the transparent screen section <b>22</b>.

0103Accordingly, since the fixing unit <b>23</b> is inserted into and fixed to the protection cover <b>10</b>, the protection cover <b>10</b> and the transparent member <b>21</b> are assembled in one piece.

0104Meanwhile, according to another embodiment of the present invention, as shown in <figref idref="DRAWINGS">FIG. 3</figref><i>a</i>, the transparent section <b>20</b> may be formed in a size the same as that of the display screen P.

0105As described above, since the entire normal display content may be displayed on the display screen P of the mobile device M if the transparent section <b>20</b> is configured to have a wide area in correspondence with the entire area of the display screen P, the user may confirm the content while viewing the display screen P without opening the protection cover <b>10</b>, and this will be described below in detail.

0106In addition, according to still another embodiment of the present invention, as shown in <figref idref="DRAWINGS">FIGS. 2</figref><i>c </i>and <b>3</b><i>b</i>, there is provided a mounting cover <b>30</b> which is additionally mounted after removing the existing rear cover assembled on the rear surface of the mobile device M.

0107In addition, since mounting cover <b>30</b> is connected to the protection cover <b>10</b> through a connection member <b>40</b>, the protection cover <b>10</b> performs an action of covering or uncovering the display screen P while rotating using the connection member <b>40</b>.

0108At this point, while the display screen P is covered with the protection cover <b>10</b>, the display screen P is protected, and the content of the display screen P may be viewed through the transparent section <b>20</b>.

0109That is, as shown in <figref idref="DRAWINGS">FIGS. 2</figref><i>c </i>and <b>3</b><i>b</i>, the connection member <b>40</b> is provided in the form of overlapping flexible and soft synthetic resins or fabrics capable of high frequency fusion at one side of the protection cover <b>10</b>, for the opening and closing operation of the protection cover <b>10</b>.

0110Since the connection member <b>40</b> connects the mounting cover <b>30</b> and the protection cover <b>10</b> as described above, the display screen P is opened or closed by the operation of a user for opening or closing the protection cover <b>10</b> while the protection cover <b>10</b> is mounted on the mobile device.

0111Particularly, since the protection cover <b>10</b> of the present invention has the transparent section <b>20</b>, the content of the display screen P can be confirmed without opening the protection cover <b>10</b>, and thus the number of opening and closing the protection cover can be reduced compared with the case of using a basic protection cover <b>10</b>, and it may exhibit an outstanding effect of using the mobile device for an extended period of time.

0112In addition, the protection cover <b>10</b> described below as shown in <figref idref="DRAWINGS">FIG. 5</figref> includes an outer member <b>50</b> and an inner member <b>51</b>, and when the protection cover <b>10</b> is configured to includes the reinforcement member <b>60</b> inside thereof, it may be formed in a structure of attaching the inner circumference of the opening section <b>11</b> to the protection cover <b>10</b> through high frequency fusion.

0113In addition, resting shoulders <b>24</b> are provided by forming the inner side of the fixing unit <b>23</b> of the transparent member <b>21</b> to have steps, and an adhesive member <b>52</b> such as a double-sided tape is provided at the resting shoulders <b>24</b>.

0114Accordingly, the transparent member <b>21</b> is attached and assembled on the inner circumferential surface of the opening section <b>11</b> by the adhesive member <b>52</b>.

0115According to the configuration described above, since the transparent member <b>21</b> is attached to the opening section <b>11</b> after the protection cover <b>10</b> is completed, the transparent member <b>21</b> of further diverse materials may be selectively installed according to the design of the protection cover <b>10</b>.

0116The transparent member <b>21</b> described above for finishing the transparent section <b>20</b> may be preferably formed of transparent or semitransparent synthetic resin having a conductive function, and the transparent member <b>21</b> may be formed through injection molding or manufactured by mechanically processing a thin plate of a PC material having excellent transparency and high strength.

0117Particularly, the transparent member <b>21</b> and the fixing unit <b>23</b> may be configured in one piece as shown in <figref idref="DRAWINGS">FIG. 1</figref><i>b</i>, and when the protection cover <b>10</b> is formed of a fabric capable of high frequency fusion as described below, the fixing unit <b>23</b> may be formed to be extended from the transparent screen section <b>22</b> in the shape of a plate without separately providing the reinforcement member <b>60</b> between the fabrics so as to function as the reinforcement member <b>60</b> instead.

0118According the configuration described above, since the reinforcement member <b>60</b> is not required, the protection cover may be manufactured in one piece by directly adhering the outer member <b>50</b> and the inner member <b>51</b> of a fabric capable of high frequency fusion to both sides of the fixing unit <b>23</b> using the adhesive member <b>52</b>, it is effective in that the manufacturing process and cost can be reduced.

0119In addition, the transparent member <b>21</b> may be formed of a tempered glass or a half mirror, and the tempered glass has a transparency higher than that of the PC material and may provide a feeling of high quality if it is applied to the protection cover <b>10</b>.

0120In addition, when the half mirror is applied as the transparent member <b>21</b>, it may exhibit an additional effect of providing a function of a mirror when the display screen P does not emit light so that a user may use the mobile device in substitution for a mirror although the user does not separately carry a mirror, and when the mobile device operates, light is emitted from the display screen P, and the key information displayed on the display screen P may be conveniently confirmed through the half mirror.

0121In addition, since the PC material, the tempered glass and the half mirror are manufactured to have a conductive function, some functions may be handled by touching the display screen P although the protection cover <b>10</b> is closed, and the user is provided with convenience of confirming the content of the display screen P and handling the touch functions without opening the protection cover <b>10</b>.

0122According to still another embodiment of the present invention, the transparent member <b>21</b> provided in the protection cover <b>10</b> of the present invention configured as described above may be formed in a variety of forms on the front surface of the protection cover <b>10</b> in a size corresponding to the position and outer size of the key information F or the display content shown on the display screen P.

0123That is, the key information F displayed on the display screen P is generally displayed in the vertical or horizontal direction.

0124To this end, the transparent member <b>21</b> according to the present invention may be formed, for example, in the horizontal direction on the protection cover <b>10</b> as shown in <figref idref="DRAWINGS">FIG. 1</figref><i>a</i>, or alternatively, the transparent member <b>21</b> may be formed on the protection cover <b>10</b> to be extended long in the vertical direction as shown in <figref idref="DRAWINGS">FIGS. 2</figref><i>a </i>and <b>6</b>.

0125In addition, according to still another embodiment of the present invention, when the transparent member <b>21</b> is formed on the protection cover <b>10</b> in the horizontal or vertical direction, it may be formed to be placed at one side of the protection cover <b>10</b> as shown in <figref idref="DRAWINGS">FIG. 2</figref><i>a. </i>

0126As described above, the transparent member <b>21</b> according to the present invention may provide a design of placing the transparent member <b>21</b> at one side end of the protection cover <b>10</b>, as well as a design of arranging the transparent member <b>21</b> in the horizontal or vertical direction, according to the arrangement of the key information F displayed on the display screen P of the mobile device.

0127Accordingly, since the users may selectively choose and use the protection cover <b>10</b> of the present invention according to the arrangement of the key information F of the display screen P unique to each mobile device manufacturing company, the present invention applying the transparent member of the protection cover <b>10</b> having a wide variety of arrangement forms provides user-oriented convenience.

0128Meanwhile, according to still another embodiment of the present invention, as shown in <figref idref="DRAWINGS">FIG. 2</figref><i>c</i>, the fixing unit <b>23</b> described above is extendedly formed in the area other than the transparent member <b>21</b>, and the outer member <b>50</b> and the inner member <b>51</b> are attached to both sides of the fixing unit <b>23</b> in one piece using the adhesive member <b>52</b>.

0129In addition, according to still another embodiment of the present invention, the reinforcement member <b>60</b> may be further provided between the fixing unit <b>23</b> and the outer member <b>50</b> and between the fixing unit <b>23</b> and the inner member <b>51</b>.

0130This is a configuration for forming the protection cover <b>10</b> when the protection cover <b>10</b> is formed of a fabric that can be fused using a high frequency or an ultrasonic wave. In the case of a fabric that cannot be fused, the protection cover <b>10</b> is formed of a fabric that does not react to a high frequency by forming a thermoplastic adhesion film or an adhesion layer reacting to a high frequency on the inner surface of the fabric.

0131That is, as shown in <figref idref="DRAWINGS">FIG. 2</figref><i>c </i>or <b>3</b><i>b</i>, the transparent member <b>21</b> is arranged at an outer side or at the center of the protection cover <b>10</b> in the vertical or horizontal direction, and the fixing unit <b>23</b> may be formed by extending the other part of the protection cover <b>10</b> in one piece.

0132In this case, the outer member <b>50</b> and the inner member <b>51</b> are formed of a fabric, and the reinforcement member <b>60</b> or the like does not need to be additionally assembled between the fabrics.

0133That is, the fixing unit <b>23</b> is arranged between the fabrics instead of the reinforcement member <b>60</b>, and the protection cover <b>10</b> is formed by attaching the reinforcement member <b>60</b> together with the outer member <b>50</b> and the inner member <b>51</b> using the adhesive member <b>52</b>.

0134Since the transparent member <b>21</b> integrated with the fixing unit <b>23</b> instead of the reinforcement member <b>60</b> as described above does not separately need the reinforcement member <b>60</b>, the manufacturing process is simplified, and the manufacturing cost and unit price are lowered.

0135Meanwhile, according to still another embodiment of the present invention, as shown in <figref idref="DRAWINGS">FIG. 3</figref><i>a</i>, the protection cover <b>10</b> has a frame unit <b>12</b> formed along the edges of the display screen P.

0136The transparent member <b>21</b> is formed within the area of the frame unit <b>12</b> in a size corresponding to the display screen P and exposed outside.

0137The transparent section <b>20</b> is formed at a portion of the protection cover <b>10</b> in order to display the key information F in the embodiment described above, whereas the transparent section <b>20</b> is formed in a size the same as the entire area of the display screen P in this embodiment, and accordingly, the frame unit <b>12</b> is formed to assemble the transparent member <b>21</b> together with the protection cover <b>10</b>.

0138Accordingly, the fixing unit <b>23</b> of the transparent member <b>21</b> is formed along the edges of all the four sides, and the fixing unit <b>23</b> is assembled to be inserted into the frame unit <b>12</b>.

0139According to the configuration described above, the entire content of the display screen P may be confirmed through the transparent member <b>21</b> without opening the protection cover <b>10</b>.

0140In addition, the mobile device may be used by touching the display screen P from outside after turning on the display screen P by pushing a button of the mobile device through the transparent member <b>21</b>.

0141As a result, the user may confirm the content of the display screen P and conveniently use the mobile device by touching the display screen P without frequently opening the protection cover <b>10</b>.

0142In addition, since the protection cover <b>10</b> protects the display screen P, an external shock does not make a scratch, and it is effective in that the mobile device can be used for an extended period of time without making a scratch on the display screen P although an expensive protection film. or the like is not attached.

0143Meanwhile, according to still another embodiment of the present invention, function holes <b>13</b> are formed on the protection cover <b>10</b> at positions corresponding to functional components arranged on the front surface of the portable mobile device M.

0144Accordingly, it is preferable to essentially provide the function holes <b>13</b> at one side of the protection cover <b>10</b> according to the present invention.

0145The function holes <b>13</b> are configured as a selective combination of, for example, a communication speaker hole <b>14</b>, a front side camera hole <b>15</b>, a user recognition hole <b>16</b> and a light sensor hole <b>17</b>.

0146In addition, at one side of the protection cover <b>10</b>, a push button display unit <b>18</b> is further provided at a position corresponding to a function button unit or a touch button unit of the portable mobile device M.

0147According to the configuration described above, since a communication speaker, a front side camera, a user recognition sensor and a light sensor arranged at the upper and lower portions of the front surface of the mobile device are exposed outside through the function holes <b>13</b> when the protection cover <b>10</b> covers the display screen, each of the functions may be appropriately performed although the protection cover <b>10</b> covers the display screen.

0148Particularly, the push button display unit <b>18</b> is formed to easily confirm the position of a push button while the protection cover <b>10</b> covers the display screen P when the push button provided at a lower portion of the mobile device is handled even when the display screen P is covered with the protection cover <b>10</b>.

0149This is a configuration for manufacturing the protection cover <b>10</b> considering the functional components arranged in a way unique to each mobile device manufacturing company and considering a case of adding a component having an additional function other than the functions described above or removing a component.

0150In addition, according to still another embodiment of the present invention, the transparent member <b>21</b> is assembled to be inserted into the protection cover <b>10</b> while maintaining a minute gap D between the bottom surface thereof and the display screen P so as not to contact with each other.

0151That is, if the protection cover <b>10</b> of the present invention is installed and used, the display screen P may be sufficiently protected although a protection film is not attached in a conventional way of using the mobile device without a protection cover.

0152However, since hardness of the transparent member <b>21</b> is similar to that of the display screen P if a transparent synthetic resin, a tempered glass or a half mirror is used as a material of the transparent member <b>21</b>, a scratch or a shock may be generated since the transparent member <b>21</b> contacts with the display screen P while opening or closing the protection cover <b>10</b>.

0153Accordingly, in the present invention, in order to prevent such a problem, the transparent member <b>21</b> is configured to maintain a minute gap D with the display screen P so that the bottom surface of the transparent member <b>21</b> may not contact with the display screen P when the transparent member <b>21</b> is installed and assembled in the protection cover <b>10</b> as shown in <figref idref="DRAWINGS">FIG. 7</figref>.

0154Since the bottom surface of the transparent member <b>21</b> maintains a minute gap with the display screen P, the protection cover <b>10</b> does not directly contact with the display screen P when the protection cover <b>10</b> covers the display screen P, and since the inner member <b>51</b> of the protection cover <b>10</b> formed of a fabric having a soft sense of touch, such as velvet or suede, directly contacts with the display screen P, a scratch is not made at all.

0155Meanwhile, according to still another embodiment of the present invention, whether or not the protection cover <b>10</b> is mounted may be confirmed when the protection cover <b>10</b> having the transparent section <b>20</b> is mounted on the mobile device.

0156That is, as shown in <figref idref="DRAWINGS">FIG. 8</figref>, the protection cover <b>10</b> of the present invention is configured to have a mounting cover <b>30</b> additionally mounted after removing the existing rear cover assembled on the rear surface of the mobile device M, and since the protection cover <b>10</b> is connected to the mounting cover <b>30</b> through a connection member <b>40</b>, the display screen P may be protected.

0157Accordingly, a mount sensor unit <b>70</b> is provided at one side of the rear surface of the mobile device so that the mobile device may sense assembly of the mounting cover <b>30</b> when the mounting cover <b>30</b> is assembled on the rear surface of the portable mobile device M after separating the existing rear cover.

0158In addition, a mount recognition unit <b>80</b> is provided on the inner side of the mounting cover <b>30</b> so that the mount sensor unit <b>70</b> may recognize whether or not the mounting cover <b>30</b> is mounted.

0159The mount recognition unit <b>80</b> may be configured in a contact type mechanically contacting with the mount sensor unit <b>70</b> or a non-contact type maintaining a gap between the mount recognition unit <b>80</b> and the mount sensor unit <b>70</b>.

0160The contact type may be configured in a variety of ways. For example, the mount sensor unit <b>70</b> is configured as a micro switch or a tact switch, and the mount recognition unit <b>80</b> may be configured in the form of a push projection protruding on the inner surface of the mounting cover <b>30</b>. In this case, the rear cover is formed not to have the push projection so as to recognize the combined state of the mounting cover <b>30</b>.

0161In addition, in the case of being configured as a non-contact type, the mount sensor unit <b>70</b> may be configured as a photo sensor or a magnetic sensor, and the mount recognition unit <b>80</b> may be formed as a blocking piece for blocking or passing light of the photo sensor or formed as a magnetic substance of a metallic material associated with the magnetic sensor.

0162Accordingly, if the mounting cover <b>30</b> is mounted after the rear cover of the mobile device is separated, the push projection, the blocking piece or the magnetic substance of a metallic material operates the switch, the photo sensor or the magnetic sensor, and the mobile device electrically recognizes whether or not the mounting cover <b>30</b> provided with the protection cover <b>10</b> is mounted.

0163To this end, it may be configured such that if the mounting cover is installed, the key information F displayed on the display screen P of the portable mobile terminal M is displayed only in the area of the transparent member <b>21</b> of the protection cover <b>10</b>.

0164That is, the key information F is displayed on the display screen P as much as corresponding to the screen area of the transparent member <b>21</b> of the protection cover.

0165At this point, the transparent member <b>21</b> is formed at a portion of the front surface of the protection cover <b>10</b> as described above and displays only essential content F, or the transparent member <b>21</b> is formed to have a transparent member <b>21</b> having an area the same as the size of the front surface and displays the entire content of the display screen P.

0166Accordingly, the user may conveniently handle the mobile device by touching the surface of the transparent member from outside without opening the protection cover <b>10</b> while confirming the key information F of the display screen P through the transparent member <b>21</b>.

0167Meanwhile, according to still another embodiment of the present invention, a sensing means <b>110</b> for sensing opening and closing of the protection cover <b>10</b> is further provided, in addition to the configuration of sensing whether or not the protection cover <b>10</b> is mounted.

0168That is, as shown in <figref idref="DRAWINGS">FIGS. 9 and 10</figref>, the sensing means <b>110</b> for determining whether or not the protection cover <b>10</b> covers the display screen P is embedded in the protection cover <b>10</b>.

0169To this end, a circuit connection unit <b>130</b> is provided on the rear surface of the mobile device, and the sensing means <b>110</b> is configured to be electrically connected with the circuit connection unit <b>130</b>.

0170A connection terminal <b>120</b> is embedded inside the mounting cover <b>30</b>, and the connection terminal <b>120</b> is configured to turn on or turn off the display screen P according to the opening or closing state of the protection cover <b>10</b> in association with the control circuit unit of the mobile device M while transmitting and receiving a signal informing an opening or closing state to and from the circuit connection unit <b>130</b> in wired or wireless communication.

0171According the configuration described above, the mount sensor unit <b>70</b> which determines the installation state of the protection cover <b>10</b> may be systematically associated with the sensing means.

0172That is, if the mounting cover <b>30</b> is installed in order to mount the protection cover <b>10</b> after separating the rear cover of the mobile device, the mobile device recognizes that the mounting cover <b>30</b> having the protection cover <b>10</b> is mounted through the mount recognition unit <b>80</b> and the mount sensor unit <b>70</b>.

0173In addition, depending on the type of the protection cover <b>10</b>, the mobile device may be configured to be controlled by an internal program of the mobile terminal to recognize whether the transparent member <b>21</b> is formed in a size of a part of the display screen P or in a size of the entire display screen P based on the size of the transparent member <b>21</b>.

0174Accordingly, since the mobile device displays the key information F on the display screen P in correspondence to the size of the transparent member <b>21</b>, the user may handle the mobile device by directly touching the surface of the transparent member <b>21</b> from outside.

0175In addition, when the protection cover <b>10</b> of the mobile terminal is closed, the sensing means <b>110</b> provided on the protection cover <b>10</b> senses the closed state of the protection cover <b>10</b> and recognizes whether or not the protection cover <b>10</b> covers the mobile device through the connection terminal <b>120</b> and the circuit connection unit <b>130</b>.

0176If a character message or a missed call arrives at the mobile device in this state, the mobile device displays normal content displayed on the display screen P when the display screen P is not covered with the protection cover <b>10</b> and displays the key information F only in the area of the transparent member <b>21</b> when the protection cover <b>10</b> covers the display screen P.

0177In this manner, the protection cover <b>10</b> according to the present invention allows the mobile device to recognize whether or not the protection cover <b>10</b> is installed through the mounting cover <b>30</b> in association with the mobile device, and then the protection cover <b>10</b> senses that the display screen P is covered with the protection <b>10</b> covers and displays the key information F on the display screen P in correspondence to the size of the transparent member <b>21</b>.

0178Accordingly, the protection cover <b>10</b> of the present invention is configured to exhibit an outstanding effect of handling the mobile device by touching the protection cover <b>10</b> even when the protection cover <b>10</b> covers the display screen P, unlike a conventional protection cover <b>10</b> which performs only a function of safely protecting the display screen P of the mobile device.

0179According to still another embodiment of the present invention, the sensing means <b>110</b> described above may be configured of a magnetic sensor, an illuminance sensor, a photo sensor or a proximity sensor.

0180That is, when the photo sensor or the illuminance sensor is applied as the sensing means <b>110</b> installed inside the protection cover <b>10</b>, the sensing means <b>110</b> may detect whether or not the protection cover <b>10</b> covers the display screen P by sensing the light of the display screen P, and when the proximity sensor is applied as the sensing means <b>110</b>, the sensing means <b>110</b> may detect whether or not the protection cover <b>10</b> covers the display screen P by sensing the distance between the display screen and the protection cover <b>10</b>.

0181In addition, in the case of the magnetic sensor, a magnetic substance or the like associated with the magnetic sensor may be installed around the display screen P of the mobile device to sense whether the protection cover <b>10</b> is opened or closed in association with the protection cover <b>10</b>.

0182As described above, according to the sensor type and the sensing method, the protection cover <b>10</b> itself may apply the sensing means <b>110</b> mounted on the protection cover <b>10</b> without changing the specification of an existing mobile device, and when a mobile device manufacturing company itself manufactures the protection cover <b>10</b> to be compatible, the protection cover <b>10</b> may be configured to be associated with the mobile device.

0183Meanwhile, according to still another embodiment of the present invention, a configuration for installing the sensing means <b>110</b> inside the protection cover <b>10</b> is also provided.

0184To this end, as shown in <figref idref="DRAWINGS">FIGS. 4</figref><i>a </i>and <b>4</b><i>b</i>, the protection cover <b>10</b> includes an outer member <b>50</b> and an inner member <b>51</b>, and the transparent member <b>21</b> includes a transparent screen section <b>22</b> and a fixing unit <b>23</b> formed along the edges of the transparent screen section <b>22</b>.

0185The fixing unit <b>23</b> is configured to be fixed between the outer member <b>50</b> and the inner member <b>51</b> and assembled in one piece.

0186When the outer member <b>50</b> and the inner member <b>51</b> are made of a fabric capable of high frequency fusion or ultrasonic wave fusion, a reinforcement member <b>60</b> of a synthetic resin material for forming the protection cover <b>10</b> in a plate shape is further provided between the outer member <b>50</b> and the inner member <b>51</b>.

0187In addition, the fixing unit <b>23</b> is configured to be fixed to the reinforcement member <b>60</b> while being inserted in the reinforcement member <b>60</b>.

0188That is, according to still another embodiment of the present invention, the reinforcement member <b>60</b> may include a first reinforcement plate <b>61</b> and a second reinforcement plate <b>62</b> formed of synthetic resin.

0190In addition, the protection cover <b>10</b> having the transparent member <b>21</b> is completed by configuring the transparent screen unit <b>22</b> inside the resting unit <b>63</b> to be exposed outside through a transparent window <b>64</b> formed to communicate with the opening section <b>11</b>.

0191In addition, according to still another embodiment of the present invention, the first reinforcement plate <b>61</b>, the second reinforcement plate <b>62</b>, the resting unit <b>63</b> and the fixing unit <b>23</b> are attached by the adhesive member <b>52</b>.

0192This is a configuration for forming the reinforcement member <b>60</b> and the transparent member <b>21</b> in a plate shape, and in addition, it is preferable that the outer member <b>50</b> and the inner member <b>51</b> are attached to the outer surfaces of the first reinforcement plate <b>61</b> and the second reinforcement plate <b>62</b> by the adhesive member <b>52</b> to complete the protection cover <b>10</b> in a slim size.

0193Since the outer member <b>50</b> is exposed outside, it should be made of a fabric capable of high frequency fusion, which is durable to a shock or a scratch and has ornamental patterns of a variety of colors and shapes.

0194Since the inner member <b>51</b> is a part contacting with the display screen P, it is made of a soft fabric such as velvet or suede that will not make a scratch on the display screen P when it contacts with the display screen P.

0195In addition, according to still another embodiment of the present invention, when the sensing means <b>110</b> described above is mounted on the protection cover <b>10</b>, it is configured to accommodate a Flexible Printed Circuit Board (FPCB) <b>100</b> electrically connected to the sensing means <b>110</b> and the mounting cover <b>30</b> through the connection member <b>40</b>.

0196To this end, an accommodation groove <b>65</b> for accommodating the FPCB <b>100</b> is further provided at one side of the resting unit <b>63</b>.

0197The accommodation groove <b>65</b> is formed along a path connecting the FPCB <b>100</b>, and the depth and width thereof are determined to be matched to the depth and the width of the FPCB <b>100</b>. An adhesive member <b>52</b> such as a double-sided adhesive tape may be provided on both sides of the FPCB <b>100</b> or the accommodation grooves <b>65</b> of the first reinforcement plate <b>61</b> and the second reinforcement plate <b>62</b>.

0199A separate space for accommodating the sensing means <b>110</b> is formed between the first reinforcement plate <b>61</b> and the second reinforcement plate <b>62</b> to install the sensing means <b>110</b> inside the protection cover <b>10</b>.

0200In addition, the accommodation groove <b>65</b> for accommodating the FPCB <b>100</b> is formed to be connected to the space for accommodating the sensing means <b>110</b>.

0201In addition, the middle part of the FPCB <b>100</b> is inserted inside the connection member <b>40</b> connected to one end of the protection cover <b>10</b>.

0202The other end of the FPCB <b>100</b> is connected to the connection member <b>40</b> to be connected to the connection terminal <b>120</b> provided inside the mounting cover <b>30</b> of the mobile device, and since the connection terminal <b>120</b> is connected to the circuit connection unit <b>130</b> provided on the rear surface of the portable mobile device M, the display screen P is turned on and off according to opening and closing of the protection cover <b>10</b>.

0203The sensing means <b>110</b> described in this embodiment may be configured of a magnetic sensor, an illuminance sensor, a photo sensor, a proximity sensor or a magnetic sensor as described above, and apparently, the essential content F displayed on the display screen in response to the operation of the protection cover <b>10</b> and the mounting cover <b>30</b> in correspondence to each sensor may be confirmed through the transparent member <b>21</b>.

0204According to still another embodiment of the present invention, there is provided a protection cover for a portable mobile device interconnected with the mobile device only through opening and closing of the protection cover, without the need of tearing off the rear cover of the portable mobile device and connecting to the mobile device.

0205Generally, although a method of removing (tearing off) the rear cover of a portable mobile device and connecting a protection cover to the mobile device is advantageous in that a feeling of integrating the mobile device and the protection cover for the mobile device may be improved by appearance, it is troublesome to attach the protection cover, and a problem may occur in driving the mobile device if a plurality of electronic control means is included.

0206Accordingly, there is provided an embodiment in which a protection cover for a mobile device is attached to the outer surface of the mobile device without removing the rear cover and recognizes a state of covering the display screen P.

0207In this embodiment, the portable mobile device includes a sensing means capable of recognizing opening and closing of the protection cover <b>10</b> so as to display key information F in a portion of the display screen P corresponding to the transparent section <b>20</b> of the protection cover when the protection cover <b>10</b> covers the display screen P.

0208The protection cover for a mobile device is attached to and interconnected with the portable mobile device.

0209The protection cover for a mobile device includes the protection cover <b>10</b> having the transparent section <b>20</b> for confirming the key information F displayed on the display screen P when the mobile device M operates while the protection cover <b>10</b> covers the display screen P, and the protection cover <b>10</b> is connected to the mounting cover <b>30</b> attached to the rear surface of the mobile device M through the connection member <b>40</b> and may open and close the display screen P.

0210At least one of a magnetic sensor, a capacitive sensor, a resistive sensor and an electrical contact sensor may be adopted as the sensing means included in the portable mobile device.

0211Generally, it may be convenient to adopt the magnetic sensor or the electrical contact sensor as the sensing means.

0212In this case, the protection cover <b>10</b> will further include a magnetic material for transferring magnetic signals or a conductive material for transferring electrical signals, and when the protection cover <b>10</b> containing such a material covers the display screen P, the sensing means senses the magnetic material or the conductive material included in the protection cover <b>10</b> and informs the mobile device M of the state of covering the display screen P with the protection cover <b>10</b>.

0213In addition, there may be provided an embodiment in which the display screen P of the mobile device may be turned on or turned off according to whether or not the display screen P covers the protection cover <b>10</b>, in addition to recognizing by the mobile device that whether or not the protection cover <b>10</b> covers the display screen P.

0214Referring to <figref idref="DRAWINGS">FIG. 11</figref>, in another embodiment, the mobile device senses whether or not the display screen P covers the protection cover <b>10</b>.

0215If an incoming call is arrived in the case where it is recognized that the protection cover <b>10</b> covers the display screen P, information on the incoming call is displayed in a predetermined portion of the display screen P.

0216If notification information is arrived in the case where the protection cover <b>10</b> covers the display screen P, the notification information is displayed on a predetermined portion of the display screen P.

0217At this point, the portion of the display screen P displaying the notification information such as information on the incoming call or arrival time of the incoming call is set to be matched to the transparent section formed on the protection cover so that the user may confirm the information.

0218According to the present invention, since the front surface of a portable mobile device such as a smart phone may be safely protected even when an external shock is applied, and the content on the display screen may be confirmed or a touch function can be handled even when the protection cover is not opened, functions of the mobile device can be sufficiently used, while the mobile device is safely protected, by mounting the protection cover.

0219Furthermore, the mobile device may recognize whether or not the protection cover is mounted by the mount sensor unit included in the sensing means and the mounting cover provided on the protection cover, and in addition, the protection cover is provided so as to recognize opening and closing of the protection cover. Therefore, a user may be provided with convenience of handling the mobile device from outside through the transparent member although the protection cover is less frequently opened.
