Abstract

PURPOSE:To prevent the size of an original from being misdetected by generating a 1st state wherein light is made incident on all original size detection sensors and a 2nd state wherein the light is made incident on none of the original size sensors. CONSTITUTION:The original detecting device is so constituted that an area A1 in the internal surface of a main body cover above a 1st arm 8a and a 2nd arm 11a in the 1st state is painted 12 in black and an area A2 in the main body cover internal surface above a 1st arm 8b and a 2nd arm 11b in the 2nd state is painted in white. In this case, the output signals of all the original size detection sensors S0-S5 in said 1st and 2nd states are checked and when there is even one sensor which outputs an ON signal in the 1st state, or when there is even on sensor which outputs an ON signal in the 2nd state, it is judged that the sensor which outputs the abnormal signal or its signal transmission system is faulty.
