Abstract

PURPOSE: To avoid bumping of a pusher material against a bottom plate of a cassette and eliminate a percussion noise by controlling an acceleration of a pusher mateial with a controlling material and thereby making a motion of the pusher material smooth.
CONSTITUTION: While inserting a cassette to a main unit, an end projection 1a pushes a pin 4c of a swing lever 4, thereby the lever 4 is rotated counterclockwise resisting a spring 9. A working arm 5 having been released of the pressure, starts rotation counterclockwise by means of a spring force attached thereto, however, at the same time, a control lever 7 sustaining a force of coil spring 8 is rotated clockwise by a plate spring 4 provided at a forward end, and a rapid rotation is controlled. When the working arm 5 is further rotated and a joint of the forward end of the plate spring 4 and the pin 7a of the control lever 7 is uncoupled, the working arm 5 is released of the control of the spring 8, and being revolved by a force of the spring 10 further, pushing up the bottom plate of the cassette with the pushing lever 2 via the working arm 5 and the shaft 3 with a spring 10, so as to have a copier sheet attach a paper roller with a pressure.
