Abstract
When a paper feeding ray is set, an arm of a one-armed pinion makes a contact with an abutting member formed in a main unit to which the paper feeding tray is attached. When the paper feeding tray is pushed in, the arm is pushed by the abutting member, the one-armed pinion rotates as the rack member moves, and the one-armed pinion moves in a direction into the paper feeding tray. When a spring is stretched, a bottom plate push-up member rotates up on its rotation center and rises by a predetermined angle to press a bundle of stacked paper sheets against a feed roller, so that the paper sheets can be fed.
