Abstract

PURPOSE: To automatically set in the paper feed state in the locked state simply by loading with a cassette, by providing a lock lever to be engaged with cassette, pressure-contact means to press-fit the copying paper to paper feed roller, cassette locking means, pressure-contact releasing lever, etc.
CONSTITUTION: A paper feed device consists of paper feed roller 1, lock lever 5, pressure-contact means 10, pressure-contact releasing lever 20, and lock plate 21 to fix a cassette 32 in the loading position. When the cassette 32 is inserted, a notch step part 34 of a side plate 33 abuts against the pin 6 of lock lever 5, and the lock lever 5 is rotated. In consequence, the pin 17 of the pressure-contact means 10 releases the engagement with the lever 5, and the lever 13 is turned upwards together with a support shaft 12 by a pressure-contact spring 19, then the pressure- contact roller 15 lifts the base plate to press-fit the end of copying paper 42 to the paper feed roller 1. At the same time, the lock plate 21 of which protruding piece 23 abuts against the pin 14 of the roller 15 is turned, and the lock pawl 22 is engaged with the brim part of the cassette 32 to lock it. When the pressure-contact releasing lever 20 is turned clockwise, the support shaft 12 and arm 13 rotate also clockwise, so that said press-fitting and locking may be released, thereby allowing the cassette to be taken out.
