Therefore, even if a mark is inscribed on the surface of the recording medium 1 by, for example, a sign mark or a stamp, the mark can be erased by wiping it off and used continuously and repeatedly.

Further, the recording medium 1 is configured by, for example, a belt,
By replacing the belt with a new one after marks have been written on all areas on the recording medium, it is possible to omit the work of erasing marks written on the recording medium.

The above-mentioned recording medium l is placed outside the original copying area of the original frame 5 attached to the original platen 4, and is located in the sub-scanning direction (direction of arrow 6) with respect to the original from the home position of the optical system.
The rollers 7.8 are arranged in an endless manner on a pair of rollers 7.8 disposed on the front side and opposed to each other in the main scanning direction of the document. An opening 51 for marking marks is formed on the original frame 5 corresponding to the upper surface of the recording medium 1. A stamp stand 9 is provided on the lower surface side of the recording medium 1 corresponding to the recording medium 1 for supporting the recording medium 1 during mark imprinting.
