Abstract: <P>PROBLEM TO BE SOLVED: To provide a paper sheet detector that can accurately detect the presence of a paper sheet even when the photo-reception quantity of a photo-transistor is reduced by contamination of paper powder or the like, or even when outdoor daylight comes into the photo-transistor.  <P>SOLUTION: A light emitting diode LED1 is flickered according to an on-off operation of a transistor Tr1, and an emitter output signal is generated corresponding to the photo-reception quantity when reflected light from the paper sheet is photo-received by a photo-transistor Tr2. An alternating current component signal is extracted by a capacitor C1 alternating-current-coupled to an emitter output terminal to be brought into a signal waveform using the potential zero as a reference. The alternating current component signal is rectified by a rectifying diode D1 inside a reference voltage generating circuit 5, followed by smoothing, so as to generate a reference voltage Vref low in its voltage by a forward-directional voltage drop Vf of the diode D1 compared with a high level voltage thereof. A comparator 10 compares the reference voltage Vref generated in the reference voltage generating circuit 5 with the alternating current component signal to output a result therein.  <P>COPYRIGHT: (C)2004,JPO
