And a control unit 55 for controlling the two image reading units 56 and 57.

Further, as a storage device for various data, there is provided an optical disk 58 for storing image data read by the image reading device, search data input from the keyboard 54, and the like. The compression / expansion unit 61 is a circuit that performs data compression when storing raw data on the optical disk 58 and expands data when reading compressed image data stored on the optical disk 58.

Further, the display device includes a liquid crystal display panel 60 for displaying a keyword being searched and image information searched for, and a control unit 59 for controlling the display panel. In addition,
The control unit 59 has a VRAM for developing an image to be displayed.

FIG. 6 is a flowchart showing a process of storing image data in the second embodiment.

The duplex original image is read and the optical disk 5
When the information is stored in the keypad 8, as shown in FIG. 7, first, a keyword 70 for later searching for the original to be read this time is input from the keyboard 4 (S31). Then, the input keyword 70 is temporarily stored in the RAM 53 (S32).

Next, when the image reading operation is started (S33), the image reading units 56 and 57 provided on both the front and back sides of the original travel path respectively copy the front and back images of the original 0 to 1 Each line is converted to a corresponding analog electric signal and output to the reading control unit 55 and the display control unit 59.

The reading control unit 55 combines the image data of each line into a pair of both sides (S34), compression-encodes them (S3).
5), and temporarily store it in the RAM 53 (S36). On the other hand, the display control unit 59 stores the read image data in the VRAM
And display it on the liquid crystal display panel 60. As a method for synthesizing the image signals on both sides, a method described in Japanese Patent Application Laid-Open No. 2-179159 is used.

When the reading of the original image is completed (S37), as shown in FIG. 8, the CPU 51 extracts the compression-encoded image information from the image reading control unit 55 and sends the image information to the image information area 90 on the optical disk 58. Is found (in this case, the area 91b), and the image information in which the front side image and the back side image are combined is written to the optical disk 58 (S38). Further, a free area of the search information area 80 on the optical disk 58 (in this case, an area 81b)
The keyword 82b stored in the RAM 53, the attribute (compression method, storage date, etc.) 83b of the image information, and the address number 84b of the image information storage area are written in (S3).
9).

If the image is read with the same keyword as the already stored keyword, the image read later is regarded as being continuous after the image read earlier, For example, like the area 81c for the area 81b, search information having pointer information to another image information with the same keyword is provided.

When the images of both sides are combined and stored in this way, the state of the stored image in the vertical direction is as shown in FIG. 11 or FIG. Here, the arrow a indicates the main scanning direction of the scanner, and the arrow b indicates the direction in which the document moves, that is, the sub-scanning direction. FIG. 11 shows a case where the sub-scanning direction matches the vertical direction of the document, and FIG. 12 shows a case where they do not match.

Next, FIG. 9 is a flowchart showing the operation when searching the optical disc 58 for necessary information.

As shown in FIG. 10, first, the keyboard 5
4 to input search information of an image to be searched (S4).
1). For example, when a keyword is input and a list of search information matching the keyword is desired, the input search information is temporarily stored in the RAM 53 (S42).

Here, the CPU 51 searches for a matching keyword in the search information area 80 on the optical disk 58 based on the keyword 90 stored in the RAM 53 (S43). If a match is found (S
44), retrieve matching search information, and display control unit 59
Send to The display control section 59 displays the sent search result information on the liquid crystal display panel 60 in order (S45). The search can use not only keywords but also other attributes such as dates.

When it is desired to view the searched image information (S47), after finding the search information with the matching keyword, the image information is taken out from the optical disk 58 using the number of the image information area in the search result information. (S48), the data is expanded and decoded by the data compression / expansion unit 61 (S49), and the expanded image information is stored in the RAM 53 (S50), sent to the display control unit 59, expanded to the VRAM, and displayed on the liquid crystal display panel 60. (S51).

At this stage, the decompressed data is as shown in FIG.
1. As shown in FIG. 12, the data on the front and back are linked. Next, an instruction is given from the keyboard as to which direction the upward direction of the image on the front surface is (S52). Then, when an instruction of this direction is given, the printing operation is started (S5).
3).

At this time, for example, in the case where the instructed upward direction of the original is the direction of arrow b (corresponding to FIG. 11), first, only the image data on the front side is cut out and sent to the printer 62 in the same direction. Then, only the image data on the back side is cut out and sent to the printer 62 in the same direction. Thus, printing as shown in FIG. 13 can be performed.

In the case where the upward direction of the designated document is the direction of the arrow a (corresponding to FIG. 12), first, the image data on the front side is cut out and sent to the printer 62 in the same direction. However, the image data on the back side is rotated 180 degrees and sent to the printer 62. Thus, even when the vertical direction of the document does not coincide with the sub-scanning direction as shown in FIG. 12, it is possible to perform composite printing in which the vertical direction coincides as shown in FIG.

After this, if there is the next image (S5)
4) Return to S48 and repeat the same process.

FIGS. 16 and 17 are flowcharts showing the processing operation in the third embodiment of the present invention.

In this embodiment, when storing image data, as shown in FIG. 16, a print instruction direction is given together with a keyword (S61), and this is stored in a disk (S6).
9). Other processes are the same as those in FIG. At the time of printing, as shown in FIG. 17, the print instruction direction is read from the disk (S82), and printing is performed based on the read instruction direction (S83). The image information is stored in the RAM 53.
The operations up to display and storage in (S80, S81)
This is common with FIG.

In the case of this embodiment, since the direction is specified at the time of storage, there is an advantage that the trouble of instructing each direction at the time of printing can be omitted.
