ABSTRACT:
The present invention describes an automatic paper sheet feeding apparatus for automatically feeding a number of paper sheets one by one at regular intervals. A cylindrical bushing 10 inserted in and fixed at a automatic paper sheet feed roller shaft 3 has a detent part 10b and an elastic piece 10a allowing elastic motion to a direction of the paper sheet feed roller shaft 3. A cylindrical part 20a united with an automatic paper sheet feed gear 20 has an elastic piece 20b allowing elastic motion in the paper sheet feed roller shaft 3 direction and confronted with the elastic piece 10a of the bushing 10. The automatic paper sheet feed roller shaft 3 is inserted into the automatic paper sheet feed gear 20 through the bushing 10 so that the automatic paper sheet feed gear 20 can rotate. The elastic piece 20b of the automatic paper sheet feed gear 20 is engaged with the detent part 10 b of the bushing 10, so that the automatic paper sheet feeding operation is performed. That is, because the transmitting operation is reliably carried out without a spring clutch, the number of parts as well as the cost are decreased, and the apparatus is simplified.
