DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. 1 is a block diagram (a) and a perspective view (b) of the first embodiment of the present invention, and FIG. 2 is a flow chart for explaining the operation of the first embodiment.

The handy terminal 10 of this embodiment shown in FIG. 1 (b) has a keyboard 1 similar to the conventional example of FIG.
2. It has a printer 13. Also, in the first embodiment,
The display surface of the information input / output unit 21 is used not only for displaying information but also for reading an image.

On the reading surface of the information input / output unit 21, a two-dimensional optical sensor composed of an amorphous silicon array having a light transmitting property is arranged. Further, a display device is arranged on the back surface thereof. As the display device, a liquid crystal display with a backlight, an EL (electroluminescence) display, a fluorescent display, or the like is used. Further, the display device is used as both the display means and the document illuminating means of the reading means, and each dot of the reading sensor and each dot of the display device have a one-to-one correspondence.

When reading an original, the original is illuminated through one or a plurality of dots of a light transmissive optical sensor element corresponding to one dot of the display device, and the reflected light is irradiated by one or a plurality of dots of the corresponding optical sensor element. read. One dot of the light-transmitting light sensor element is composed of a non-light-transmitting light sensor portion and a light-transmitting layer having no sensor function.

On the side surface of the handy terminal 10, there is provided a switch 22 for executing the reading operation of the reading means of the information input / output unit 21.

In FIG. 1A, the display unit and the reading unit of the information input / output unit 21 are the amorphous silicon array 1,
The liquid crystal display 2 and the backlight 3 are laminated in this order. Data output to the liquid crystal display 2 controlled by the CPU 7 is controlled by the display controller 4 including a known display control IC.

The image information read from the amorphous silicon array 1 is read out via the image reader interface 5. The power source of the backlight 3 is supplied from a lighting power source 6 including an inverter circuit and the like.

One of the contacts of the read switch 22 is grounded and the other is C with the power supply voltage being pulled up.
It is connected to the PU 7, and the CPU 7 can recognize the operation state of the reading switch 22. The print controller 9 includes a memory 8 including a ROM 8a and a RAM storing a program of the control unit shown in FIG.
Are connected. The printer 13 is controlled by the printer controller 9 which is a known printer control circuit.

Next, the operation of this embodiment will be described with reference to FIG. In step S1, the reading switch 22
Check the pressed state of. If the reading switch 22 is on, the process proceeds to step S2, and if the reading switch 22 is off, the process proceeds to step S6. In step S6, known data input / output, printing, and other data processing are performed according to the pressed state of the keyboard 12.

On the other hand, in step S2, since reading is performed by the amorphous silicon array 1, all the pixels of the liquid crystal display 2 are turned on to improve the transmittance of the liquid crystal display 2. In step S3, the lighting power source 6
The backlight 3 is turned on via.

In step S4, the image information output from the amorphous silicon array 1 is read via the image reader interface 5. At this time, the illumination light of the backlight 3 is applied to the original 14 via the liquid crystal display 2 and the amorphous silicon array 1, and the reflected light is input to the amorphous silicon array 1 to cause the original 14 to be read.
Image information corresponding to the above characters and symbols is input from the amorphous silicon array 1.

In step S5, output processing of the input image information of the original 14 is performed. Here, for example, the read image information is output to the printer 13 via the print controller 9. In step S5, the image information is simply stored in the memory 8 and is output to the liquid crystal display 2 as needed.

In this way, according to this embodiment, the information input / output unit 21 of the handy terminal 10 is arranged on the desired reading area on the original 14 and the reading switch 22 is provided.
The image of the document 14 can be read by pressing.

FIG. 3 is a perspective view showing a second embodiment of the present invention. The difference from the first embodiment is that the printer 13 of FIG.
When reading the document, the document 14 with its reading surface facing down is set on the information input / output unit, and the document 14 is read by
1 is read by pressing the original pressing cover 17 so as to be in close contact with the sheet 1.

If the handy terminal 30 is provided with a facsimile communication function, it can be used as a facsimile device which reads the information input / output unit 21 and serves as a display (alternative to recording) means.

In this way, the first and second embodiments are
The reading unit is two-dimensional, and there is no need for manual scanning as in the conventional case.
The image can be read easily by simply pressing, the handling of the device is very easy, and there are few failures.

Further, since the display surface and the reading surface are common, there is no need for a scanner section separate from the main body or a reading surface independent of the display surface as in the conventional case, and the entire apparatus can be miniaturized. Is.

Although the handy terminal is used as the embodiment, the same configuration can be applied to various image processing apparatuses for displaying and reading images.
