PURPOSE:To prevent the wasteful consumption of a toner at the time of printing and to enable the erasing of arbitrary points so that a fine print is obtd. by using >=3 layers of liquid crystal plates to constitute transparent members for sandwiching a microfilm. CONSTITUTION:The transparent members for sandwiching the microfilm are constituted of >=3 layers of the controllable liquid crystal plates. For example, the lower transparent member 100 is constituted of one layer of the liquid crystal plate and the upper transparent member 200 of 2 layers of the liquid crystal plates. The print is thereby obtd. in such a manner that the toner does not stick to the unnecessary parts on the outside of the image frame and the prints from which the arbitrary part of the image is removed to prevent adhesion of the toner is obtd. with the simple and compact constitution; in addition, the fine print without contg. unnecessary lines is obtd. The distinct boundary where the toner sticks and the part where the toner does not stick is obtd. and the checking of said boundary with a screen is possible. |
