Abstract
A conveyor receives and holds a recorded sheet discharged from an image forming apparatus, the sheet is conveyed along a path and another conveyor is provided along the path at a predetermined distance from the first conveyor to further convey the sheet. There is a shifting device between the two conveyors for holding and individually shifting groups each containing a prescribed number of sheets, perpendicularly to the conveying direction of the sheets. There is a delivery tray for receiving the sheets delivered by the other conveyor.
Claims14
A sheet finishing apparatus comprising:
- (a) a first conveying means for receiving and holding a recorded sheet discharged from a discharging section of an image forming apparatus and for conveying the recorded sheet along a sheet conveyance path;
- (b) a second conveying means at a predetermined distance from the first conveying means, said distance being less than a length, in the sheet conveying direction, of a minimum size of sheet to be conveyed, whereby the recorded sheet conveyed by said first conveying means is conveyed by said second conveying means;
- (c) a shifting means, which does not convey the recorded sheet in an ejecting direction, between the first and second conveying means for substantially shifting sets of a predetermined number of recorded sheets, set by set, in each of a plurality of shifting positions of a direction perpendicular to the conveying direction of the recorded sheet;
- and
- (d) a delivery sheet tray for receiving the recorded sheet delivered by the second conveying means.
A sheet finishing apparatus comprising:
- (a) a conveying means for receiving and holding a recorded sheet discharged from a discharging section of an image forming apparatus and for conveying along a sheet conveyance path;
- and
- (b) a low speed ejecting means provided in a vicinity of a sheet exit port on a downstream side of the conveying means with respect to a sheet conveyance direction for ejecting the recorded sheet to a delivery sheet tray at a sheet conveyance speed less than that of the conveying means,
- wherein the low speed ejecting means shifts sets of a prescribed number of recorded sheets, set by set, in a direction perpendicular to a conveying direction of the recorded sheet while an ejecting operation is carried out, thereby the sheets are delivered to the delivery sheet tray while being shifted.
