ABSTRACT:
A sorter in which a stepwise bin driving mechanism which includes helical cams moves bins, which are arranged in multiple steps, sequentially and intermittently to a sheet delivery position for loading the respective bins with sheets. The sorter includes pin guides and support frames which are constituted by side plates each being provided with an elongate slot for guiding a pin, which is provided on each side of the base end of a bottom plate of each bin. Cam members are provided at both sides of the other or free end of each bin. The cam members of the lowermost one of the bins have a greater height than those of the other bins so that, while the sorter is in a sort mode, the space available above the bottom plate of the lowermost bin for receiving sheets becomes greater than those available above the other bins. A bin drive motor which serves as a drive source for the bin driving mehanism is implemented with an AC reversible motor. A motor stop control circuit is associated with the reversible motor for rectifying AC current to apply braking current to the reversible motor. A mechanism for transporting a sheet to the delivery position includes drive and driven rollers which constitute a transport roller pair. Each of the drive rollers is provided at one end thereof with a flange which is greater in diameter than that portion of the drive roller which makes contact with its associated driven roller.
