装置。[Claim for Utility Model Registration] A paper feed roller driven by a first drive shaft via a one-way clutch, and a paper feed roller that pulls the paper fed from the paper feed roller at a paper feeding speed higher than the paper feeding speed. The one-way clutch includes a paper roller and a paper detection mechanism disposed between the two rollers, and the one-way clutch is connected to the first drive shaft so that the speed at which the paper is transported between the rollers is regulated by the paper feeding speed. On the other hand, in an automatic paper feeder configured to allow free rotation in the paper feeding direction, a coupling means is provided that has a predetermined angular play in the rotational direction between the drive shaft of the one-way clutch and the first drive shaft. An automatic paper feeder characterized in that the paper feeder is connected via a paper feeder.
