Claims

[Claims for Utility Model Registration] A copying machine configured to push up the lowermost surface of a plurality of copy sheets stacked and stored in a case on the front end side in the sheet feeding movement direction, away from the bottom plate of the case. In the paper feed cassette, a stopping claw is brought into contact with the uppermost surface of the front end side of the copy paper, and a gap is provided between the stopping claw, through which the copy paper to be fed is inserted. a regulating plate that regulates the front end surface number of the plate; and a regulating plate that protrudes in a vertical direction from the upper end of the stopping pawl or the lower surface of the regulating plate so as to come into frictional contact with the lower surface or upper surface of the copy sheet being fed. A paper feed cassette for a copying machine, comprising a pair of stacked flexible sheet members whose protrusion amount on the front side in the direction of movement is larger than the protrusion amount on the rear side.
