Abstract:
A paper detecting apparatus of an electrophotographic processor, comprising:a first actuator having one end thereof hinged to hinge means for producing a displacement depending on whether paper is loaded on a paper support;an L shaped second actuator having a center thereof hinged to said hinge means for producing a displacement depending on a paper transport state;sensing means for outputting different signals according to an abutment state of said sensing means with an end of said second actuator;elastic means for controlling the abutment state of said sensing means with said end of said second actuator according to a paper loading state, and for connecting said first actuator and said second actuator such that abutment between the end of said second actuator and said sensing means is released during paper transport;a timer which measures time periods of the different signals outputted by said sensing means to produce output values; anda control unit which determines the paper loading state and the paper transport state according to the output values of said timer and an on/off state of said sensing means.
