[Problems to be Solved by Conventional Techniques and Inventions]

As the number of portable electronic devices such as cordless phones and personal organizers grows, designing these devices in a lightweight and compact format that is easy to carry is an increasing priority. While users can enjoy the portability of such devices, it is still required to carry multiple devices at the same time in order to freely use bidirectional voice and data communications. Having to carry separate devices for cordless phones and personal organizers is annoying to users. Moreover, these devices typically require separate charging devices, and confusion involving multiple devices with multiple charging devices can be very inconvenient for the user. Therefore, a portable communication device incorporating two-way voice and data communication is required.

[Example]

FIG. 1 of the accompanying drawing shows a portable radio or handset 100 according to the present invention. The handset 100 described here provides two-way voice communication with a personal organizer. In a preferred embodiment, the handset 100 is a second generation cordless telephone (CT2), but other communication devices such as cellular telephones can also employ the invention . The handset 100 includes a housing 102, a flap or front cover 104 attached to the housing via a hinge 106. The flap 104 contains multiple keys to perform dialing, scrolling menus and other similar functions related to cordless phones. The handset 100 also includes an antenna 110 as a means of transmitting and receiving radio frequency signals. In a preferred embodiment of the invention, the plurality of keys 108 are included as part of a keypad membrane sandwiched between two pieces of plastic for forming the flap 104. Other materials, such as a piece of rubber, can also be used to form the flap 104, including the key 108. The flap 104 also includes a scrolled menu and a display window that displays information generated by pressing key 108. The pressure surface behind each key (shown in Figure 2) moves a certain distance when the key is pressed, and is a touch-sensitive screen (touch-sensitive screen) without damaging the screen. ) (Illustrated later).

Within the hinge 106 is a sensor switch that detects movement by the flap 104 between the first position, i.e., the open state and the second position, i.e., the closed state. In a preferred embodiment of the invention, the handset 100 acts as a CT2 telephone when the flaps are in the closed position, allowing the user to use the front keypad for normal CT2 telephone functions. When the flap is opened, a sensor switch in the hinge 106 signals a controller located in the housing 100 to signal that the handset will switch to the function of a personal organizer well known in the art.

【0005】

Next, with reference to FIG. 2, the handset 100 with the flap 104 in the open position is shown. By opening the flap 104, a switch located within the hinge 106 detects the change in flap position and sends a signal to the controller section, which causes the display or lens 202 coupled to the housing 102 to act as a personal organizer. Can function. When the flap 104 is in the open position and exposes the entire display 202, the user gains access to the full-featured lighting table provided by the display 202 to write notes, memorize messages, etc. on it. Sketch and perform other data manipulations. The display 202 is preferably a touch-sensitive liquid crystal display (LCD) that responds to a minimum amount of pressure. ). The display 202 is a touch-sensitive film or other similar means of receiving data input. The data is transferred to the display 202 through the form of a key press when the flap 104 is closed, and is transferred as handwritten data when the flap is opened. Preferably, the stylus (pen) 112 located in the holding sleeve 114 on the side of the handset 100 is removed and used as a writing instrument for sending handwritten data to the display 202 when the flap 104 is closed.

【0006】

Again, as shown in FIG. 2, the pressing surface 204 is located above the inside of the flap 104. When the key 108 is actuated from the front with the flap 104 closed, pressure is preferably transmitted through the pressing surface 204 to the touch-sensitive actuating portion 206 corresponding to each key in the display 202. Each pressing surface 204 aligns with the corresponding actuating portion 206 when the flap 104 is in the closed position. When the pressing operation of each key is started by the user, the pressing surface 204 moves by a predetermined distance and comes into contact with the corresponding operating portion 206. These actuating parts 206 are illustrated for purposes of explaining the function of the key when the flap 104 is closed. When the user opens the flap 104, the actuating part 206 no longer functions as a keypad. Also on the inner flap 104 is a bumper 208, preferably made of rubber material, which defines the key 108 and the associated pressing surface 204 from the surface of the lens 202 when the flap 104 is in the closed position. Set apart by the distance of. The bumper 208 helps prevent accidental key presses and protects the lens 202 from damage and scratches.

【0007】

While the flap 104 is in the open position and the handset 100 operates as a personal organizer, signal information can be received by the antenna 110 and the user can receive the incoming call notification. In that case, the user can close the flap 104 and use the handset as a cordless phone to answer the call.

【0008】

The handset described according to the present invention provides two modes of operation by combining two-way voice communication with a personal organizer. The combination of a cordless handset and a personal organizer reduces the number of electronic devices that users have to carry around. The handset described by the present invention can also be charged from a single charging device, eliminating the need for multiple charging devices. The cover or flap provides better protection for the lens from breakage and dust when in the closed position.

【0009】

Although preferred embodiments of the present invention have been illustrated and described, it is clear that the present invention is not limited thereto. Numerous improvements, modifications, modifications, substitutions and equivalents will be possible to those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
