Abstract

A sheet processing apparatus which is capable of improving operability while suppressing an increase in apparatus size. In a front cover insertion mode, an insertion sheet for a front cover is inserted into a bundle of sheets on which images have been formed, and in a rear cover insertion mode, an insertion sheet for a rear cover is inserted into the bundle of sheets. Insertion sheets for the front cover and insertion sheets for the rear cover are set with the same orientation in a manual feed tray 105. An insertion sheet for the front cover stored in the manual feed tray 105 is conveyed to a finisher 500 in one of a face-down state and a face-up state. An insertion sheet for the rear cover stored in the manual feed tray 105 is conveyed to the finisher 500 in the other of the face-down state and the face-up state. The insertion sheets for the front cover and for the rear cover conveyed from the manual feed tray 105 and the sheets on which images have been formed are stacked on the finisher 500.

Claims9

Dependent claims

A sheet processing apparatus comprising:

an insertion sheet feeding unit configured to feed a plurality of insertion sheets stacked on a feeding tray, the plurality of insertion sheets including a first insertion sheet that constitutes a front cover of a bundle of sheets at one side thereof and a second insertion sheet that constitutes a rear cover of the bundle of sheets at one side thereof, the first insertion sheet and the second insertion sheet being stacked on the feed tray while the second insertion sheet is placed under the first insertion sheet with both the one side of the first insertion sheet and the one side of the second insertion sheet placed facing-up;
a sheet stacking tray on which the bundle of sheets, which constitute the first insertion sheet, the second insertion sheet, and at least one recording sheet, are stacked;
a first conveying section configured to convey one insertion sheet among the plurality of insertion sheets so that one side of the one insertion sheet is placed facing-down on said sheet stacking tray;
a second conveying section convey another insertion sheet among the plurality of insertion sheets so that the one side of the another insertion sheet is placed facing-up on said sheet stacking tray;
and
a conveying controller configured to control:
said first conveying section to convey the first insertion sheet so that the first insertion sheet is stacked on said sheet stacking tray with the one side of the first insertion sheet placed facing-down;
and
said second conveying section to convey the second insertion sheet so that the second insertion sheet is stacked on said sheet stacking tray with the one side of the second insertion sheet placed facing-up, when a mode that appends the front cover and the rear cover to the bundle of sheets is selected.
