Claims

[Scope of Claim for Utility Model Registration] A hopping roller that is rotatably supported and has a roughly half-moon cross section is stopped with the string side facing downward, and the arc surface of the abutment means that sandwiches the hopping roller in the axial direction. A first pressing section that presses the separation pad to abut against the first pressing section, and a second pressing section that presses the cassette paper loaded in the cassette and comes into contact with an arcuate surface adjacent to the first pressing section. In a paper feeding mechanism of an electrophotographic printer device, which further includes an upper plate that guides manual paper to a second pressing part and rotates a hopping roller to feed out cassette paper or manual paper, A flange is provided at the end of the atsupah plate to protrude from the outer circumferential surface of the hopping roller and is oriented in the paper feed rotation direction, or the end of the contact means in the paper feed direction is extended to a position that protrudes from the outer circumferential surface of the hopping roller to prevent paper jams. A paper feeding mechanism for an electrophotographic printer apparatus, characterized in that the paper feeding mechanism of an electrophotographic printer device is provided with a paper jamming paper guide section that stops the hopping roller with the string side facing downward when removing paper.
