<p>PROBLEM TO BE SOLVED: To provide a sheet paper feeder capable of reducing any load applied to a drive gear when any load more than the specified level is added to a sheet paper supplying roller so as to prevent any skip, deformation, breakage, etc., of the teeth of drive gear. SOLUTION: Driving force is transmitted in order of a drive gear 109, a drive shaft 108, a pin 112, an engaging part 111, and a paper sheet feed roller 103, and when any load more than the specified one is applied to the paper sheet feed roller 103, engagement between the engaging part 111 and the pin 112 is temporarily released, the drive shaft 108 becomes rotatable with no relation to the load so that the drives shaft 108 can run idly.</p> |
