To display. By this display, if the operator does not find the document to be searched, he / she inputs the search condition again.
If found, the image to be searched is specified from the list (specified by the document number, etc.) and the search execution is instructed.

The CPU 34 reads the record number corresponding to the designated image using the page management table 21b of the search data, reads the logical address corresponding to the read record number from the record management table 21c,
A physical track address and a physical sector address corresponding to this address are calculated, and an image is reproduced from the optical disk 19 by the optical disk device 20 using these addresses.

The CPU 34 also supplies the image (compression information) for each scanning line supplied from the optical disk device 20 to the compression / expansion circuit 50, performs band expansion processing, and sequentially supplies the page memory 40.

Next, the CPU 34 reads the display direction parameter file stored in the magnetic disk 26 according to the image size information of the record management table 21c stored in the main memory 38, and supplies it to the page memory 40. After determining the display direction of the displayed image, the rotation processing circuit 48 rotates the image according to the determination and outputs the image to the display memory 42, and the image is stored in the display memory 42. The display control unit 44 displays the stored contents of the display memory 42 on the CRT display device 24.

As described above, according to the above embodiment,
When the image stored in the optical disk 19 is read out and displayed on the CRT display device 24, the image is rotated and displayed in a display direction set in advance according to the image size (document size), so that the image is sequentially rotated. There is nothing to do. It is possible to eliminate troublesome image rotation work by the operator.
