摘要： In order to provide a configuration capable of correcting skew and lateral displacement of a sheet, a pair of regulation guides are capable of guiding opposite end edges in a sheet width direction of a sheet S conveyed by a conveyance belt and spheres, while being nipped. Further, the pair of regulation guides are capable of shifting to guide positions for guiding the opposite end edges of the sheet, and retract positions retracted from the opposite end edges of the sheet more than the guide positions, wherein a control section conveys the sheet by the conveyance belt in a state in which the pair of regulation guides are positioned in the retract positions, and brings a front end of the sheet in a state of being conveyed by the conveyance belt into contact with a conveyance roller pair with drive halted.

摘要： A pair of regulating guides is disposed on both sides of a conveying belt in a sheet width direction Y, each having a support surface that supports an end edge in the width direction of the sheet conveyed while being nipped by the conveying belt and balls and a guide surface that faces the end edge of the sheet in the width direction. Each of the pair of regulating guides is movable to a first guide position at which the end edge of the sheet in the width direction is supported by the support surface and guided by the guide surface and to a second guide position at which the end edge of the sheet in the sheet width direction is supported by the support surface and which is retracting further away from the end edge in the sheet width direction than the guide position.

摘要： The present invention is to provide a configuration capable of stably conveying a sheet irrespective of the basis weight of the sheet. A pair of regulating guides is disposed on both sides of a conveying belt in a sheet width direction Y, each having a support surface that supports an end edge in the width direction of the sheet conveyed while being nipped by the conveying belt and balls and a guide surface that faces the end edge of the sheet in the width direction. Each of the pair of regulating guides is movable to a first guide position at which the end edge of the sheet in the width direction is supported by the support surface and guided by the guide surface and to a second guide position at which the end edge of the sheet in the width direction is supported by the support surface.

摘要： In order to provide a configuration capable of stably performing conveyance of sheets, a pair of regulation guides are capable of guiding opposite end edges in the sheet width direction Y of a sheet S conveyed by a conveyance belt and spheres, while being nipped. Further, the pair of regulation guides are capable of shifting to guide positions for guiding the opposite end edges of the sheet and retract positions retracted from the opposite end edges of the sheet more than the guide positions. In shifting the pair of regulation guides from the retract positions to the guide positions, a guide shift section causes the one of regulation guides to arrive at the guide position after the other of regulation guides arrives at the guide position.

摘要： To provide a configuration for allowing a user to easily take out a sheet stopped on a conveying belt. Regulating guides are disposed on both sides of a conveying belt in a sheet width direction Y and can guide both end edges in the sheet width direction of a sheet S being conveyed while being nipped by the conveying belt and the balls. A take-out port is provided on a side close to the regulating guide in the sheet width direction and serves as an opening for taking out the sheet stopped on the conveying belt. The regulating guide on a side away from the take-out port moves in the sheet width direction Y toward the take-out port when the sheet is stopped on the conveying belt.

摘要： A sheet conveying apparatus for conveying a sheet in a conveying direction includes a pair of conveying rollers receiving and conveying a sheet; an endless conveying belt conveying the sheet; a plurality of balls to be rotatable in any direction while nipping the sheet with the conveying surface; a pair of regulating guides disposed on both sides of the conveying belt; a guide moving unit that moves the pair of regulating guides; and a roller moving unit that moves at least one of the pair of conveying rollers to a nip position and a nip release position. Before a rear end of the sheet passes the pair of conveying rollers, the pair of conveying rollers is moved to the nip release position by the roller moving unit, and then, the guide moving unit makes each of the pair of regulating guides reach the guide position from the retracting position.

摘要： The present invention is to provide a configuration facilitating removal of a sheet stopped on a conveying belt. Regulating guides are disposed on both sides of a conveying belt in a sheet width direction Y and can guide both end edges in the sheet width direction of a sheet S conveyed while being nipped by the conveying belt and the balls. A take-out port is provided on the side closer to the regulating guide in the sheet width direction Y, through which a sheet stopped on the conveying belt is taken out. A guide moving part moves the regulating guides. When a sheet is stopped on the conveying belt, the guide moving part moves the first and second regulating guides such that the regulating guide is retracted to a position at which a support surface does not support a first sheet end edge.

摘要： The apparatus is capable of handling sheets of various lengths while suppressing an increase in apparatus size, wherein each of a pair of regulating guides is movable to a guide position at which an end edge of a sheet in a sheet width direction can be guided by a guide surface and to a retracting position retracting further away from the sheet width direction end edge than the guide position. For sheets S1 and S2 each having a first sheet length, the pair of regulating guides is made to reach the guide position from the retracting position in a state where the front end of the sheet is located between upstream and downstream ends of the guide surface. For a sheet S3 having a second sheet length that is longer than the first length, the pair of regulating guides is made to reach the guide position from the retracting position.

摘要： In order to provide a configuration capable of suppressing reductions in productivity of sheets, a pair of regulation guides are capable of guiding opposite end edges in a sheet width direction Y of a sheet S1 conveyed by a conveyance belt and spheres, while being nipped. Further, the pair of regulation guides are capable of shifting to guide positions for guiding the opposite end edges of the sheet, and retract positions retracted from the opposite end edges of the sheet more than the guide positions. A sheet detecting sensor is disposed on the downstream side of the conveyance belt in a conveyance direction X to detect the presence or absence of the sheet.
