Abstract
PURPOSE: To ensure the accurate optical detection for the several original paper sizes with the copying mechine by providing the light recurrent reflection layer to the original side of the original stage cover and thus obtaining the accurate detection reflected light to the sensor.
CONSTITUTION: The light from illuminator 1 irradiates original 6 on original stage 5, and the reflected light forms the electrostatic latent image onto photosensitive drum 4 through slit 11 after passing through movable mirrors 2a, 2b and 2c, lens 3 and fixed mirror 2d each. Then light recurrent reflection layer 7 is attached to the lower part of original cover 8 of the copying machine and in correspondence to the optical axes of paper size sensors 9 and 10. Thus the reception amount of the light varies at the light reception parts 9b and 10b of sensors 9 and 10 each and in accordance with the size of original put on the original stage. As a result, the accurate detection is possible for several original sizes.
