Image reader

[Detailed Description of the Invention]

(Field of the Invention] The present invention relates to an image reader, especially relates to a pen type image reader. [Description of the Prior Art] Generally the image reader which reads optically the bar code given to goods etc. is used. However, a printer special to printing this bar code to goods etc. is required, and there was inconvenient [ of being unable to decipher the contents of a bar code by viewing moreover ]. As what is replaced with this bar code, the method of presentation by character strings, such as a number or the alphabet, is adopted, and the image reader which reads that character string optically is developed variously in recent years. There is a thing of Ben Type as one sort of this image reader. The photoelectric conversion element arranged in order that this type of thing might take in the catoptric light in which the light with which it was irradiated from the light source and light source for manuscript reading was reflected in respect of the manuscript and might change it into an electric signal is attached in the pen casing made, for example from a synthetic resin, metal, etc. [ many ] And between this pen casing and the picture read control sections of the main part of a device was connected by the signal cable. By having the above-mentioned pen casing by hand, and making a nib scan to the manuscript side which should be read, in the case of this image reader, the drawing information on a manuscript side is read optically, and it has become the mechanism of transmitting that drawing information to the above-mentioned picture read control section via a signal cable. [Problem(s) to be Solved by the Invention] By the way, in the case of this conventional pen type of image reader, since what is called manuscript reading head sections, such as a light source and a photoelectric conversion element installed successively, were arranged as mentioned above in the tip part of the pen casing, the tip part of the pen casing was large. [ many ] Although it is a translation which is a thing of this Ben Type, and is scanned while following a manuscript portion in the tip part of a pen casing when reading a manuscript, since the tip part is large in the conventional thing as mentioned above, the tip part becomes obstructive -- seeing -- hard -- for example, there is a fault that it is difficult to read a manuscript side top correctly for every line. The object of the present invention cancels the fault of the conventional technology mentioned above, can make the tip part of a pen casing thin as much as possible, can read desired drawing information correctly, and is to provide the image reader of Ben Type which can moreover transmit drawing information correctly. [Means for Solving the Problem] In order to achieve the above-mentioned object, the present invention builds a light source for manuscript reading in a pen casing, A light guide [ which transmits optical information to a picture read control section of a main part of a device from the pen casing ] cable which is flexible, for example, consists of a glass fiber etc. is formed, For example, it changes optical information into an electric signal, for example, fixed a photoelectric conversion element which consists of a solid-state image sensing device array etc. on a printed circuit board, contact members, such as a plug plug, are connected to the picture read control section side tip part of the light guide cable, The contact member was removably attached to a main part of a device. [Example] Next, the example of the present invention is described with a drawing. In the perspective view of the whole image reader, and Drawing 2, the control block diagram of the image reader and Drawing 4 of the partial expanded sectional view of a pen and Drawing 3 are [ Drawing 1 ] explanatory views of a contact member. An image reader applied to the example of the present invention as shown in Drawing 1, It mainly comprises pen 2 for drawing information reading connected to display device 1 provided with a controller, a screen, a data channel, etc., and its display device 1, keyboard 3 which has the function key connected to the above-mentioned display device 1, etc. A tip part of pen casing 4 where pen 2 was fabricated, for example with polyacetal resin, aluminum, etc. as shown in Drawing 2 has a narrow diameter. A tip part is arranged at a line in light source 6 which consists of LED etc., and the scanning direction of pen 2 and a direction which intersects perpendicularly, and the middle is arranged side by side at the inner side so that optical fiber bunch 5 for manuscript reading which is flexible may turn to a manuscript side. 19 in a figure is a support member which supports the above-mentioned optical fiber bunch 5, and this optical fiber bunch 5 is inserted, as it penetrates along the direction of an axis and the hollow part of pen casing 4 is shown in Drawing 1, and it is connected to plug 18. Drawing 4 is an explanatory view of this plug plug 18, and as shown in the figure, CCD array 8 which has arranged the solid-state image sensing device (CCD) in - sequence is provided at the tip of the above-mentioned optical fiber bunch 5, The end of each optical fiber of optical fiber bunch 5 counters each solid-state image sensing device (CCD), and is connected optically, respectively. As for the end and CCD array 8 of optical fiber bunch 5, attachment is being firmly fixed to the prescribed position of printed circuit board 21 by metal fittings 20. As shown in the figure, many contact terminals 22 electrically connected with CCD array 8 are provided in the other end of this printed circuit board 21. The plug plug mouth in which the side of display device 1 is formed as shown in Drawing 1 is removably equipped with plug plug 18 which stored the above-mentioned CCD array 8 and printed circuit board 21. As shown in Drawing 3, it is a control part of this image reader, Central operation processing unit (CPU) 10, read-only memory (ROM) 11, random-access-memory (RAM) 12 input-and-output Boat Elephant 1013, CCD drive 14, light source 6, CCD array 8. amplifier (AMP)15.2 value-ized circuit 16, and an in-series bit It comprises S/P converter 17 etc. which are changed into a parallel bit. It has pen 2, when reading a picture, the tip part of that is contacted to manuscript side 7, as shown in Drawing 2, and the manual scan of the pen 2 is carried out along the reading direction of a manuscript. By doing so, the light with which it was irradiated by light source 6 is reflected in respect of [ 7 ] a manuscript, and the catoptric light is taken in by CCD array 8 through optical fiber bunch 5. Thus, when the drawing information on a manuscript side is read optically, the image data outputted from CCD array 8 is AMPl, After being amplified by 5 and forming 2 values in 2 value-ized circuit 16, serial data are changed into parallel data by S/P converter 17, and it is that the predetermined address of RAM12 will memorize via ON appearance Pau 1-13. [Effect of the Invention] The present invention makes the tip part of a pen casing a narrow diameter by inserting the photoelectric conversion element which takes breadth in comparison as mentioned above, storing to contact members, such as a plug, and storing the light guide cable used as a light source and a light sensing portion to a pen casing. If it does in this way, when going later on, the position which the present tip part is putting understands a manuscript side clearly like before in the tip part of a pen casing. Therefore, it can input easily and properly that it locates [ which he wishes / manuscript ], and operativity becomes good. Photoelectric conversion elements, such as a CCD array, are directly fixed to a printed circuit board, Because the contact member which stored these was electrically connected to the main part of a device, The connection between a light guide cable and a photoelectric conversion element and connection between a photoelectric conversion element and a printed circuit board become certain, therefore transfer of the optical information read with the pen is performed properly, and a reliable image reader can be provided.
