US 5,345,303 A · Sheet sorter having aligning member

Abstract

A sheet sorter includes a plurality of bins for receiving sorted sheets, a sheet discharging unit for discharging the sheets to the bins, a shifting unit for raising and lowering the plurality of bins in order to selectively face a bin to the sheet discharging unit, an aligning reference wall for regulating one end portion of a sheet discharged to the bin, and an aligning member for bringing the one side portion of the sheet into contact with the aligning reference wall by pushing the other side portion of the sheet. The sheet sorter further includes a controller for controlling the aligning member so as to vary the timing of alignment start depending on whether operation is during normal sorting wherein the bin receiving the sheet at a position facing the sheet discharging unit rises after receiving the sheet or during reverse sorting wherein the bin receiving the sheet descends.

Dependent claims

A sheet sorter comprising:

a plurality of bins for receiving sorted sheets;
sheet discharging means for discharging sheets to said bins;
shifting means for selectively raising or lowering said plurality of bins in order to selectively align an opening of one of said plurality of bins with said sheet discharging means;
a first aligning member for regulating a side portion of a sheet discharged into said one bin;
and
a second aligning member for bringing said side portion of the discharged sheet into contact with said first aligning member by pushing against an opposing side portion of the sheet;
where said sheet sorter further comprises:
control means for variably controlling said second aligning member so as to start alignment of a discharged sheet at one timing after receiving the discharged sheet during a first sorting mode wherein the shifting means raises a bin receiving the discharged sheet after receiving the discharged sheet, and at a second timing after receiving the discharged sheet during a second sorting mode wherein the shifting means lower a bin receiving the discharged sheet after receiving the discharged sheet.

wherein said sheet sorter further comprises:
control means for variably controlling said second aligning member so as to start alignment of the sheet at one timing during first mode sorting wherein the bin receiving the discharged sheet rises after receiving the sheet and at a second timing during second mode sorting wherein the bin receiving the sheet descends after receiving the sheet;
wherein during first mode sorting said control means controls in a manner whereby the second aligning member pushes the sheet against the first aligning member before the bin completes its upward shift.
