Abstract

PURPOSE: To detect that paper sheets accomodated in a pile in a paper feeding cassette are fed out and used up by providing a paper feeding mechanism with a switch.
CONSTITUTION: A friction plate 18 for preventing a double feeding is provided with a guide 21 for holding a switch pressing piece 20 at the lower side thereof. A paper feed roller 9 is adapted to press an actuator 25a by dint of a sliding displacement motion of a slider mechanism 23 and operate a switch 25, to thereby detect that paper sheet is out.
