Abstract
PURPOSE: To offer the title pusher which has lowered dispersion in a pushing force and hardly generates skew during sheet-feeding, by attaching a direct releasing member to a roller-supporting plate, and supporting a pushing force- applying elastic body with a stationary member to control the pushing force.
CONSTITUTION: The back side of a plate spring 21 is inserted into an escape hole 24, and the positioning hole 27 of the plate spring is brought in line with a projection 26. Thus, the plate spring 21 is positioned. The pin 12 of a roller-supporting plate 10, while being brought in line with the opened part 19 of the plate spring 21, is pushed down. A stopper 13 is locked at the release part 15 of a resetting lever 16. The deflection amount of the plate spring is determined by very small number and positions of parts such as a fulcrum part 28 and a reaction force-receiving part 29 to a stay 22. Consequently, unevenness in the deflection amount is lowered.
