Abstract

A sheet processing apparatus includes a processing tray; a conveyance roller for conveying a sheet towards a downstream side in a sheet conveyance direction; a pinch roller for moving between a first position away from the conveyance roller and a second position close to the conveyance roller, and to sandwich the sheet with the conveyance roller at the second position when the sheet is conveyed by the conveyance roller. The apparatus further includes an extruding member for extruding an upstream end of the sheet from the upstream side towards the downstream side to convey the sheet placed on the processing tray. The apparatus additionally includes a controller for conveying the sheet with the extruding member after the sheet is conveyed by the pinch roller and the conveyance roller when the sheet on the processing tray is conveyed to the downstream side in the sheet conveyance direction.

Claims18

Dependent claims

A sheet processing apparatus, comprising:

a processing tray configured to stack a sheet;
a conveyance roller, arranged on a downstream side in a sheet conveyance direction with respect to the processing tray, configured to convey the sheet towards the downstream side in the sheet conveyance direction;
a pinch roller configured to move between a first position distal from the conveyance roller and a second position proximate to the conveyance roller, and to sandwich the sheet with the conveyance roller at the second position when the sheet is conveyed by the conveyance roller;
an extruder configured to extrude an end of an upstream sheet in the sheet conveyance direction from an upstream side towards the downstream side in the sheet conveyance direction to convey the sheet placed on the processing tray;
and
a controller configured to control the conveyance roller, the pinch roller and the extruder to move the pinch roller to the second position when the sheet placed on the processing tray is conveyed to the downstream side in the sheet conveyance direction, move the pinch roller to the first position from the second position after the sheet is conveyed by the pinch roller and the conveyance roller, and then convey the sheet with the extruder.

3 more elements

A sheet processing method, comprising:

arranging a conveyance roller on a downstream side in a sheet conveyance direction with respect to a processing tray in which a sheet is stacked,
causing the conveyance roller to convey the sheet towards the downstream side in the sheet conveyance direction;
providing a pinch roller to move between a first position distal from the conveyance roller and a second position proximate to the conveyance roller, and to sandwich the sheet with the conveyance roller at the second posit ion when the sheet is conveyed by the conveyance roller;
causing an extruder to extrude an end of an upstream sheet in the sheet conveyance direction from an upstream side towards the downstream side in the sheet conveyance direction to convey the sheet placed on the processing tray;
and
controlling, by a controller, the conveyance roller, the pinch roller and the extruder to move the pinch roller to the second position when the sheet placed on the processing tray is conveyed to the downstream side in the sheet conveyance direction, move the pinch roller to the first position from the second position after the sheet is conveyed by the pinch roller and the conveyance roller, and then convey the sheet with the extruder.
