PURPOSE:To easily prevent the fogging of an image to a masking part by switching the operation of a partial blank for intercepting a part of reflected light from an original in an optical path to a photosensitive body exposed with light projected from a light source. CONSTITUTION:When an ordinary paper sheet is used, a lever 4b is operated, so that one side 4a of a blank shutter as the partial blank having a bi-secting configuration is integrated with a blank shutter 4, and fixed by a pawl 4c fixed on one side 4a of the blank shutter 4. On the other hand, when the surface of a postcard 7 passes, the lever 4b is put down via a hinge part 4d as an operating mechanism, to rotate one side 4a (a side where a stamp part passes) of the blank shutter having the bi-secting configuration, and to fix it in a state so as to cover a selfock 5. Therefore, when the original is scanned, an exposure is executed as usual, the reflected light from an original platen 2 is intercepted on the closed blank shutter 4a, and the light from a fluorescent lamp 3 is directly exposed to erase an image. |
