Abstract

Provided is a sheet processing apparatus, including: a regulation portion configured to contact with an end edge of a sheet to be conveyed and to regulate a position of the sheet; a position adjustment portion configured to perform position adjustment on a sheet in a direction along an end edge of the sheet of which the end edge is in contact with the regulation portion; a folding portion configured to perform folding processing on a sheet which has been regulated by the regulation portion; and a control portion configured to execute: a first mode of causing the folding portion to perform the folding processing on a sheet which has been regulated by the regulation portion, without causing the position adjustment portion to perform the position adjustment on the sheet; and a second mode of causing the position adjustment portion to perform the position adjustment with respect to the regulated sheet.

Dependent claims

A sheet processing apparatus comprising:

a conveying portion configured to convey a sheet;
a placement portion on which a sheet which has been conveyed by the conveying portion is placed;
a regulation portion configured to contact an edge of a sheet which has been placed on the placement portion, and to regulate a position of the sheet;
an alignment portion configured to perform an alignment operation on a sheet in a direction along the edge of the sheet;
a folding portion configured to perform folding processing on a sheet which has been regulated by the regulation portion;
and
a control portion configured to execute a first mode and a second mode,
wherein in the first mode, (i) the control portion causes the conveying portion to convey a sheet to the placement portion, after which the edge of the sheet which has been placed on the placement portion contacts the regulation portion, and then the control portion causes the folding portion to perform the folding processing on the sheet which has contacted the regulation portion, and in the first mode, (ii) the control portion causes the alignment portion not to perform any alignment operation on the sheet, the edge of which has contacted the regulation portion, in a direction along the edge of the sheet, and
wherein in the second mode, the control portion causes the conveying portion to convey a sheet to the placement portion, after which the edge of the sheet which has been placed on the placement portion contacts the regulation portion, and then the control portion causes the alignment portion to perform the alignment operation on the sheet, the edge of which has contacted the regulation portion, in a direction along the edge of the sheet.

a conveying portion configured to convey a sheet;
a placement portion on which a sheet which has been conveyed by the conveying portion is placed;
a regulation portion configured to contact an edge of a sheet which has been placed on the placement portion and to regulate a position of the sheet;
an alignment portion configured to perform an alignment operation on a sheet in a direction along the edge of the sheet;
a folding portion configured to perform folding processing on a sheet positioned at a folding processing position;
a moving portion configured to move a sheet which has been regulated by the regulation portion, to the folding processing position;
and
a control portion configured to execute a first mode and a second mode,
wherein in the first mode, (i) the control portion causes the conveying portion to convey a sheet to the placement portion, after which the edge of the sheet which has been placed on the placement portion contacts the regulation portion, then the control portion causes the moving portion to position the sheet, the edge of which has contacted the regulation portion, at the folding processing position, and then the control portion causes the folding portion to perform the folding processing on the sheet which has been positioned at the folding processing position by the moving portion, and in the first mode, (ii) the control portion causes the alignment portion not to perform any alignment operation on the sheet, the edge of which has contacted the regulation portion, before the control portion causes the moving portion to position the sheet at the folding processing position, and
wherein in the second mode, the control portion causes the conveying portion to convey a sheet to the placement portion, after which the edge of the sheet which has been placed on the placement portion contacts the regulation portion, then the control portion causes the alignment portion to perform the alignment operation on the sheet, the edge of which has contacted the regulation portion, in a direction along the edge of the sheet, then the control portion causes the moving portion to position the sheet, the edge of which has contacted the regulation portion, at the folding processing position, and then the control portion causes the folding portion to perform the folding processing on the sheet which has been positioned at the folding processing position by the moving portion.
