Abstract
PURPOSE: To improve the accuracy of detection by providing a plurality of reflecting positions.
CONSTITUTION: Two light emitting diodes LD 2, LD 3 are disposed to a reflection type object detector 45' disposed on an original platen glass 14, in proximity to a photo transistor PT' as a photo detector, at the same angle to the original platen glass 14 and at varying heights. Then, at the time when the original 47 being fed to the inside of the space 44 on the originla platen glass 14 passes the low position in the space 44, the light of the light emitting diode LD 2 is radiated and when it passes the high position, the light of the light emitting diode LD 3 is radiated and the reflected light thereof is surely detected in the photo transistor PT'. Hence, the original 47 is effectively detected even when it is conveyed while waving.
