摘要： A sheet feeding device includes a first feeding roller pair, a reference member, an obliquely feeding roller, a second feeding roller pair, a detecting portion, and a controller. Before a sheet is obliquely fed by the obliquely feeding roller, the controller causes the first feeding roller to move the sheet to a predetermined position in a widthwise direction of the sheet on the basis of a detection result of the detecting means.

摘要： A sheet feeding device includes a sheet feeding portion, a side end regulating portion, a feeding portion, first and second feeding roller pairs, an abutment member, an obliquely feeding roller pair, and first and second contact-and-separation mechanisms. Feeding of a long sheet is stopped after the sheet is fed to an upstream side of the second feeding roller pair by the feeding portion, and then is resumed in a state in which the first feeding roller pair is changed from a separated state to a feedable state and in a state in which the obliquely feeding roller pair is put in a separated state, and then the sheet is fed to the second feeding roller pair. A short sheet fed by the first feeding roller pair is obliquely fed by the obliquely feeding roller pair and then is fed to the second feeding roller pair.

摘要： A sheet conveyance apparatus includes a first oblique-feed unit and a second oblique-feed unit configured to convey the sheet while approaching the sheet to an abutment surface; a changeover unit configured to change over an abutment pressure of the first oblique-feed unit on the sheet; and a control unit configured to execute a first operation for driving the first oblique-feed unit at a first speed and the second oblique-feed unit at a second speed and a second operation for driving the first oblique-feed unit at a third speed higher than the first speed and the second oblique-feed unit at a fourth speed higher than the second speed after the sheet is abutted against the abutment surface by the first operation. The control unit controls the changeover unit so that the abutment pressure of the first oblique-feed unit in the second operation is higher than that in the first operation.

摘要： A sheet conveying apparatus has a first pair of conveying rollers which nip and convey a sheet, a reference surface provided along the sheet conveying direction, a second and third pair of rotary members, which, obliquely with respect to the sheet conveying direction, conveys the sheet so as to contact the side edge of the sheet to the reference surface, a switching unit which switches the first pair of rotary members between a state of nipping the sheet and a state of nip releasing the sheet, a controller which, after controlling the second pair of rotary member and the third pair of rotary members to nip the sheet nipped by the first pair of rotary members, controls the switching unit to release nip of the sheet by the first pair of rotary members. There is no pair of rotary members that conveys the sheet in the sheet conveying direction between the second pair of rotary members and the third pair of rotary members in the sheet conveying direction.

摘要： A sheet conveyance apparatus including: an oblique-feed unit configured to convey a sheet by imparting to the sheet nipped a force in a direction inclined relative to a sheet conveyance direction so that the sheet approaches an abutment surface in the width direction as the sheet proceeds downstream in the sheet conveyance direction; a drive unit configured to drive the oblique-feed unit; a change unit configured to change the force of the oblique-feed unit; and a control unit configured to control the drive unit and the change unit so that, after causing the sheet to abut against the abutment surface in a first state in which the oblique-feed unit is driven at a first speed, the oblique-feed unit is put into a second state in which the oblique-feed unit is driven at a second speed higher than the first speed and the force is weaker than in the first state.
