Claims

[Scope of utility model registration request]

An automatic paper feed roller, a support member provided near the automatic paper feed roller, a spring receiver fixed to the support member, and a support member and the spring receiver between the support member and the spring receiver. a friction plate holder movably supported between the support member and the friction plate holder, and a rear end side inserted between the support member and the friction plate holder, and a front end side pressed against the outer peripheral surface of the automatic paper feed roller. A friction plate made of a flexible and highly elastic material is interposed between the spring receiver and the friction plate holder, and the friction plate is held between the support member and the friction plate holder. a spring that urges the friction plate holder in a direction such that , the rear end side is fixed to the friction plate holder without the force of the spring, while the leading end side is brought into contact with the outer peripheral surface of the paper feed roller, so that the automatic paper feed roller and the a first guide plate that adjusts the overlapping shape of the leading end of the paper that is being fed toward the friction plate; and a rear end side that is fixed to the support or holding material without relying on the force of the spring. On the other hand, a second guide plate is provided on the leading end side of the automatic paper feed roller at a position closer to the paper supply destination than the contact portion between the automatic paper feed roller and the first ice inner plate, and is pressed against the outer circumferential surface of the automatic paper feed roller. An automatic paper feeder comprising:
