Also, as shown in Figure 6, the storage period for each mark input in 5 step ■ is determined according to the importance of the image information: large mark M1...10 years, medium mark M2...5 years, small mark M3. ...2 years. For example, when photographing the bump images 71 to 75, if the mark types are sequentially instructed as large mark M1, medium mark M2, small mark M3, small mark M3, large mark M1, large mark M1 is For frame 71.75, the CPU 60 calculates the storage period from 1987+10=1997 to December 1997, and similarly for frame 72, which has the medium mark M2, 1987+5=
The storage period from 1992 to December 1992 is calculated, and for frame 73.74 with the small mark M3, the storage period from 1987+2=1989 to December 1989 is calculated. Each storage term calculated in this way is output to the erasable recording device 9 in 5 steps, as described above.

As described above, in this embodiment, when photographing the document P, the storage period corresponding to the type of search marks M1 to M3 on the microfilm F is input, and the storage period is calculated according to the importance of the image information. By inputting the signal to the erasable recording means 9, it is possible to improve the efficiency of erasing and editing operations in the erasable recording means 9.

In this embodiment, the types of search marks are large, medium,
Although the case of a small search mark has been described, the present invention is not limited to this, and can be applied to devices having various search marks.

For example, if the next page marked with the large mark M1 in FIG. 6 is also important, the image of the next page marked with the large mark M1 can be saved by inputting a program to the CPU 60 in advance. It is also possible to set a longer period.

Furthermore, in this embodiment, the search mark to be placed on the microfilm F is configured to correspond to the storage period of the read image information in the erasable recording means 9. It may be configured such that the information is input in correspondence with the above.

Furthermore, in this embodiment, a device for photographing image information of a document on microfilm, etc. has been described, but it may also be applied to a microfilm reader that reads photographed microfilm by photoelectric conversion. If the configuration is such that a signal indicating the storage period is output in accordance with the size of the search mark on the film, the same effect as that of the first embodiment can be obtained.

In addition, in this embodiment, the storage period is used for automatically erasing the read image information; however, when copying the information from the erasable recording means 9 to another recording medium, this If you retrieve information based on the retention period,
It becomes possible to copy information according to the purpose, such as old and important information and the latest information.

(Effects of the Invention) In the present invention having the above configuration and operation, a signal indicating the retention period of read image information based on the image signal is generated in response to the original image signal obtained by the photoelectric conversion means. Since output is possible, it is now possible to automatically erase any information recorded on the erasable recording medium, and it is possible to erase read image information and improve the reliability and residue rate of editing work. can.
