Abstract

PURPOSE:To improve reliability and durability of a device reduced in its noise and vibration by providing a control means which controls driving power of a driving means in accordance with load torque applied to the driving means in a manner wherein a bin vertically moves in a fixed speed. CONSTITUTION:A microcomputer 53 inputs an output of a sheet detecting sensor Q, bin position detecting sensor 40 and a home position detecting sensor 42, controlling a motor 25 to be driven. While the microcomputer 53 recognizes a copying machine C to be in copying operation while a signal input from an input terminal I0 is in an H level, controlling a motor driving circuit 59 in accordance with the rise-up of an input signal from the input terminal I0 and starting the reset action of each bin in a bin train to a home position. Here, in accordance with load torque applied to the motor 25, by controlling its driving power, a bin moving speed lowers, and a device, reducing the generation of noise and vibration or the like caused by the bin movement, improves reliability and durability.
