ABSTRACT:
An automatic paper sheet feeding device for a copying machine has a cassette with a base plate made of magnetic material which is secured by a magnet to a bottom plate of the cassette against a biasing force of a spring. The device has a cam member which enters a slot in the cassette after the cassette has been inserted into the device. This raises the base plate upwardly which releases the base plate from the magnetic holding force allowing the base plate to rotatingly move upwardly and contact a feeding roll due to the force of the spring.
