Claims
- 1. A sorter having a helical cam bin driving mechanism for moving a plurality of bins, which are arranged in multiple steps stacked one upon another sequentially and intermittently to a sheet delivery position to deliver sheets to each of said respective bins, said sorter comprising:
- a bin group made up of said bins, each of said bins being provided with pins which protrude sideways from both sides of a base end of a bottom plate of said pin and aligned so as to be engaged by said helical cam;
- bin support frame members for supporting the bins such that said bins are movable individually to the sheet delivery position, said bin support frame members being provided with pin guides in which the pins of said bins are slidably received wherein said bin support frame members includes a pair of side plates which face each other, the pin guides having elongate slots each being formed through a respective one of said side plates, each of said elongate slots having an abutment at an upper end thereof for engagement with the pins and wherein said plates having means fixedly attached thereto so as to fix each side plate to each other at the top and bottom thereof such that said bins are disposed therebetween; and
- a drive means for driving said helical cam of said bin driving mechanism including an AC reversible motor, and a motor stop control circuit for, while said AC reversible motor is deenergized, rectifying an AC power source to apply braking current to said motor over a predetermined period of time.
- 2. A sorter as claimed in claim 1, further comprising an outer frame constituting a housing of said sorter, an inner frame surrounding the bin group and bin support frame members and having guides for guiding said support frame members movably, said side plates being provided with rotatable rollers each being guided by a respective one of said guides of said inner frame.
- 3. A sorter as claimed in claim 1, wherein each of the bins of the bin group comprises:
- cam members provided at both sides of a free end of said bin, each of said cam members consisting of a horizontal section extending in a same direction as the bottom plate of each of said bins, and an inclined section inclined relative to said horizontal section.
- 4. A sorter as claimed in claim 3, wherein the inclined section of each cam member of a lowermost one of the bins has a greater height than the inclined sections of the other bins.
- 5. A sorter as claimed in claim 4, wherein while said sorter is not in a sort mode, spaces available above the individual bins for receiving sheets are equal to each other and, while said sorter is in a sort mode, said space available above the lowermost bin becomes greater than said spaces available above the other bins.
- 6. A sorter as claimed in claim 1, further comprising a sheet transporting mechanism for transporting a sheet coming out from an apparatus, to which said sorter is connected, to the delivery position, said sheet transporting mechanism comprising an upper and a lower guide plates and a pair of transport rollers having drive rollers and driven rollers which are held in pressing contact with and driven by said drive rollers, each of said drive rollers being provided at one end thereof with a flange which is greater in diameter than that portion of said drive roller which makes contact with said driven roller associated with said drive roller.
