A lens system 15. A mirror 16 and an image sensor 17 are provided.

The irradiated light is not reflected on the characters 12, but is reflected on white parts other than the characters 12, and the reflected light is collected by the lens system 15 and sent to the image sensor 17 via the mirror 16. That is, the image of the characters 12 recorded on the document 11 is projected onto the light-receiving surface of the image sensor 7, and the image sensor 17 converts the optical image into image data.

The image buffer 18 has a capacity to hold the image data input from the image sensor 17 for one page of the document 11, and has a function of sending out the image data when the input of one page worth of image data is completed. Note that image data is retained.

The compression unit 19 has a function of compressing the image data sent from the image buffer 18 and sending it out to the line.

The file control unit 21 has the function of transferring data sent from the reading unit 1 via the line to the operation unit 3, and
It has a function of controlling the registration and search of data in the registration file 22 according to commands from the registration file 22.

The registration file 22 is an electronic file composed of, for example, a magnetic disk, and holds registered image data.

The decompressing unit 31 has a function of decompressing compressed and transmitted data and sending it to the refresh memory 32.

The refresh memory 32 stores one of the documents 11 that have been sent.
It has a function of holding data for pages, and the held data is displayed on the CRT 34 by the CRT control unit 33.

The CRT control unit 33 has a function of controlling the display of the takes held in the refresh memory 32 on the CRT 34.

The keyboard 35 has operation buttons for activating the reading section 1, instructing the CRT 34 to display data, and for instructing cutting operations, registration, and retrieval of data displayed on the CRT 34.

Since it has such a configuration and function, when registering the document 11, the keyboard 35 is read by the operator.
In response to the display instruction, the document 11 is transported by driving the transport section 13 of the reading section 1, and the image of the characters 12 on the document 11 is read by the image sensor 17 and sent as image data to the image buffer 18, and the image of one page is read. When the data is held, the data is compressed by the compression unit 19 and sent out to the line.

The file control section 21 transfers the received data to the decompression section 31 of the operation section 3 via a line. The decompressed data is held in the fresh memory 32 and displayed on the CRT 34 by the CRT control section 33 like the image of sentence w11 in FIG.

Then, the operator operates the keyboard 35 while looking at the displayed image of the document 11 to select the part to be registered, that is,
The cutout section 11a is specified and a registration instruction is given.

Then, a command signal is sent to the specified cropping unit 1 to extract the image data held in the image buffer 18 of the reading unit 1.
Only the portion 1a is sent out and sent to the file control unit 21 through compression al; 19, and is registered in the registration file 22 by the file control unit 21 as registered image data.

The image data in the image buffer 1B is then erased.

When searching, when the registration number of a registered document is specified by the operator's operation on the keyboard 35, the file control unit 21 reads the image data of the specified document 11 from the registration file 22, and The image data is sent to the refresh memory 32 via the decompression section 31 of No. 3, and is displayed on the CRT 34 by the CRT control section 33.

In this way, necessary portions of the document 11 can be registered and searched.

However, according to the conventional method, the image buffer 118
requires a capacity to hold image data for one page of document 11, for example, A6 size (height 105mm, width 14mm)
8mm) reading resolution 9.45 dots/mm T:
If M is taken, an image buffer 18 with a capacity of about 170 KB will be required.

On the other hand, the refresh memory 32, which has an area for displaying expanded data on the CRT 34 in the vertical and horizontal directions of, for example, F6 format, is provided with a memory capacity of about 240 KB.

Having such a large capacity of memory in the reading section 1 and the operation section 3 has the drawback of increasing the cost, and also, once one page of image data is stored in the image bath sofa 18, it is stored in the refresh memory 32. Since the data is transferred, there is a drawback that it takes a long time for the CRT 344 to display the image.
