ABSTRACT:
A spring clutch includes a driving-side boss integrally formed with a driving gear and a driven-side boss having a feed roller fixed. The driving-side and driven-side bosses are arranged on a common axis so as to be opposed to each other. A coil spring is wound on the peripheral side of the driving-side boss and driven-side boss. The spring clutch further has a sleeve fitted over the coil spring while a driving-side coil end of the coil spring is engaged with the sleeve. As rotation of the coil spring and the sleeve is restricted by a projection formed on the peripheral surface of the sleeve, the coil spring is idly fitted on the driving-side boss so that the rotation of the driving-side boss is not transmitted to the driven-side boss while the reverse rotation of the driven-side boss is restricted.
