検出装置。[Claims for Utility Model Registration] (1) In a copying machine having a toner fixing device using flash lamp light, a set of copy paper presence detection optics provided within the range affected by the flash light of the flash lamp. Copy paper detection in a flash fixing section, characterized in that two sets of amplifier circuits with different amplification factors are connected to the sensor, and the output of one of them is adopted as a detection value of the presence or absence of copy paper depending on the presence or absence of flash light. Device. (2) Copying paper in a flash fixing unit according to claim 1 of the utility model registration claim, in which two sets of optical sensors with different sensitivities are arranged instead of connecting different amplification circuits to the optical sensor to obtain different outputs. Detection device.
