Abstract

PURPOSE: To make it possible to detect the original size accurately with a simple structure, by fixing and arranging the light receiving part, which receives the color light, outside the light path of the copying picture forming light.
CONSTITUTION: Coloring member 2 is provided on platen cover 1, and color sensors 4 are fixed to the nonpicture region of original platen 5 to form a light receiving part, and the reflection light from material 2 is incident to this light receiving part. Sensors 4 corresponding to the part of member 2 which is not shielded by original 6 issue the output indicating that the light of a specific wave length corresponding to the color of member 2, and sensors 4 corresponding to the part shielded by original 6 do not issue the output. consequently, the original size can be detected by information of juxtaposed sensors. Thus, accurate detection is possible.
