Abstract
A finisher connectable to an image forming apparatus for surely discharging sheets to bin trays thereof without regard to the sheet size while preventing the sheets from dropping from the bin rays or from being inaccurately positioned on the bin trays. The finisher has a discharge roller for sequentially discharging sheets driven out of the image forming apparatus to the bin trays. The rotation speed of the discharge roller is controlled on the basis of size information representative of the size of sheets to be transferred from the image forming apparatus to the finisher.
Claims14
A finisher, operatively connectable to a sheet discharging device, for finishing sheets discharged from said sheet discharging device and distributed to a plurality of bin trays which are arranged one above another in said finisher, said finisher comprising:
- a discharge roller for sequentially discharging the sheets driven out of the sheet discharging device to the bin trays;
- a drive motor for driving said discharge roller;
- and
- control means for controlling a rotation speed of said drive motor in response to size information representative of a size of the sheets sequentially discharged to the bin trays.
A finisher operatively connectable to a sheet discharging device for finishing sheets driven out of said sheet discharging device, comprising:
- a plurality of bin trays, each having a stacking surface which is inclined in an intended direction of sheet transport for receiving sheets driven out of the sheet discharging device;
- a discharge roller for sequentially discharging the sheets to said plurality of bin trays;
- positioning means comprising a pressing member for positioning the sheets stacked on said plurality of bin trays by pressing said sheets toward a reference surface;
- and
- control means for controlling a positioning operation of said positioning means on the basis of a size of the sheets such that when the sheet to be received in said bins is of a size which cannot be pressed so that it abuts against said reference surface, said pressing member is moved, before said discharge roller discharges said sheet, from a standby position to a regulating position which is adjacent to and spaced apart from the reference surface by a predetermined distance and then stopped at said regulating position.
