載の写真複写装置。[Scope of Claim for Utility Model Registration] 1. A positive film for originals is attached to the light irradiation surface formed on the bottom surface of an optical box containing a built-in light source in close contact with a screen for forming halftone dots, and this optical box is used for electronic photography. A photocopying device that is placed on a platen glass of a copying machine to copy a positive film, and two optical sensors are provided outside the light irradiation surface of the optical box and on diagonal lines of the light irradiation surface. The light source is turned on when either one of the two optical sensors receives illumination light for a relatively moving document from the electrophotographic copying machine, and then the other optical sensor is turned on when the other optical sensor also illuminates the document. A photocopying device characterized in that it is controlled by a circuit that turns off the light when it receives illumination light. 2. Registration of a utility model characterized in that a circuit is added that does not turn on even if one of the two optical sensors receives document illumination light from an electrophotographic copying machine for a certain period of time after the light source is turned off. Claim 1
Photocopying device as described in Section 1. 3. After one of the two optical sensors receives document illumination light from an electrophotographic copying machine and the light source turns on, the other optical sensor does not receive document illumination light within a certain period of time. 2. The photocopying apparatus according to claim 1, further comprising a circuit for turning off the light source when not in use.
