The operation is as follows.

The image data converted into electrical signals by the scanner 1 is developed in the page memory 228. After this data has been read in its entirety, the optical disk drive 21

If there are two or more originals, repeat the previous operations.

When all the originals have been recorded, the timer 231
The contents are recorded as directory information on the floppy disk in the floppy disk drive 212.

Note that whether or not this is the last document is input by the operator through the operation display section 4. For example, inputting the total number of sheets at the beginning of filing, or inputting a file end key when the last page is read. Further, in this embodiment, the image data was recorded on the optical disk and the directory information was recorded on the floppy disk, but the relationship between the data and the image recording medium is not necessarily fixed.

In the figure, one document is made up of three originals. The directory contains timer data during recording.

The physical start address and end address of the optical disc and other information attached thereto (for example, the total number of pages) are recorded.

(2) When executing the third function "output from image recording medium to paper", after selecting the mode, search for the target file and press the copy start button 464 to output it to paper. When searching, the directory area is displayed on the operation display section 4, but it is also possible to specify the date at this time (you can specify dates such as only February 2019 or September 2nd 2015, without specifying all dates). good), in this case, a predetermined fJjjli from the screen of one page.
Alternatively, using an area designation pointer such as a mouse, image data of a size determined from the input address is displayed. A display example is shown in FIG.
