<p>PROBLEM TO BE SOLVED: To simplify the structure of a paper jam disposing device and reduce a production cost. SOLUTION: Planetary gears 62, 68 are arranged movably along guide grooves 75a in the gear row of the drive system unit 6 of a rotation drive transmission for the paper sheet transfer means of a paper feed unit and a fixing unit and the planetary gears 62, 68 are meshed together in order that respective transfer means are rotated and driven in the paper sheet transfer direction at the normal rotation time of a drive motor 32 and the planetary gears 62, 68 are moved so as to release their meshing so that the transfer means can rotate freely when the drive motor 32 is reverse turned. The positions of respective planetary gears 62, 68 are held by a resistant plate 76 and an energizing spring 78 at respective positions.</p> |
