CONTROL METHOD FOR PAPER FEEDING APPARATUS

摘要

PURPOSE:To improve the operationability by providing a paper detection sensor in a paper feed unit to enable detection of paper existing in the paper stacking section and indicating the detection result upon throw-in of power source. CONSTITUTION:A paper feed apparatus 200 to be used together with a copy machine body 100 is provided with plural paper stacking sections 26-31 and a paper feed unit 23 liftable/lowerable along the front edge of the paper stacking sections 26-31. The paper stacking sections 26-30 are constructed movable to the right and left while the paper stacking section 31 is fixed. Here, a paper detection sensor 109 to be turned on upon contact of a paper detection filler 107 against the upper end of paper P stacked on the paper stacking section 26(-31) is provided to the paper feed unit 23. When throwing in the power source, existence of paper in all paper stacking sections 26-31 is detected prior to the copying operation and indicated on the indicating section.
