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.

An assembly of a first and a second printing or converting apparatus is each at least provided with a number of printing or converting modules disposed one after the other in a main direction, through which in use a substrate web can be guided. The first and the second printing or converting apparatuses are respectively provided with a first and a second rail assembly each extending in a main direction next to or above the associated printing or converting modules and over which at least one processing station is movable. The assembly further includes a transfer assembly which is provided with rail assemblies which are configured to move the at least one processing station from the first rail assembly to the second rail assembly and vice versa and to buffer processing stations.

A handling bar for laminated or film supports, such as paper, is disclosed, including a hollow tubular body provided with an inner cavity and an outer side surface, a plurality of through holes, arranged on the tubular body to put the inner cavity in contact with the outer side surface. The handling bar also includes at least one connection to a compressed air source or a suction device, where the connection is shaped for the inflow of compressed air or to suction air into the cavity and at least one filtering element arranged inside the tubular body where at least at one portion of the holes filters the air passing between the inner cavity and the holes.

A printing apparatus includes a printing unit configured to print an image on a sheet; a first exit path from which the sheet with the image printed thereon by the printing unit is discharged while being reversed; a second exit path from which the sheet with the image printed thereon by the printing unit is discharged without being reversed; and a switch member configured to be pivotably arranged so as to switch the first exit path and the second exit path. The first exit path passes above a pivot center of the switch member, and the second exit path passes below the pivot center.

A printing apparatus includes: a printing unit; a first conveyance unit configured to convey a sheet to the printing unit with nipping the sheet; a second conveyance unit provided on a downstream side of the first conveyance unit in a conveyance direction of the sheet, and configured to convey the sheet with nipping the sheet; a third conveyance unit provided on a downstream side of the second conveyance unit in the conveyance direction, and configured to convey the sheet with nipping the sheet; and a switching unit configured to switch a nip state of the second conveyance unit and a released state in which the nip state is released. When the sheet is conveyed by the third conveyance unit, the switching unit switches the nip state and the released state in accordance with a length of the sheet.

An image forming apparatus includes a sheet conveyance device; an image forming device including a sheet conveyance roller and a pressure roller; a memory; and a controller. The memory stores profile data indicating variation in conveyance amount in a circumferential direction due to eccentricity of the conveyance roller. The controller calculates, in intermittent conveyance processing, a correction value based on corresponding profile data for each of positions included in a width of an image to be formed in next image forming processing, the correction value being a difference between a predetermined conveyance amount and an actual conveyance amount; corrects a reference amount of rotation by a representative value of calculated correction values to calculate a corrected amount of rotation, the reference amount being an ideal amount of rotation of the conveyance roller that conveys a sheet by the predetermined conveyance amount; and rotates the conveyance roller by the corrected amount.

A pair of regulating guides can guide both end edges in a sheet width direction Y of a sheet being conveyed being nipped by a conveying belt and balls. The pair of regulating guides can move to their respective guide positions each for guiding one of both end edges of the sheet and their respective retracting positions each retracting from one of the both end edges of the sheet by a distance larger than the guide position. A guide moving unit for moving the pair of regulating guides makes each of the pair of regulating guides reach the guide position from the retracting position after the rear end of the sheet passed from a conveying roller pair positioned on the upstream side to the conveying belt passes the conveying roller pair.

A conveying device includes a rotating carrier, an inlet rotary body, an outlet rotary body, a downstream conveyor, and an inching controller. The rotating carrier carries a sheet. The inlet rotary body transfers the sheet to the rotary carrier from upstream of the rotary carrier in a conveyance direction of the sheet. The outlet rotary body transfers the sheet to a downstream area from the rotary carrier in the conveyance direction. The downstream conveyor conveys the sheet downstream from the outlet rotary body in the conveyance direction. The inching controller performs an inching operation to convey the sheet on a conveyance path including at least the downstream conveyor. The inching controller causes at least the outlet rotary body and the downstream conveyor to perform a conveying operation in conjunction with each other in the inching operation.

A sheet suction device includes a drum including multiple suction holes in a circumferential surface of the drum, the drum configured to bear a sheet on the circumferential surface and rotate, a suction device configured to suck the sheet through the multiple suction holes, a rotary valve between the multiple suction holes of the drum and the suction device, the rotary valve configured to rotate relative to the drum to change a number of the multiple suction holes communicating with the suction device, and a driver configured to relatively rotate the drum and the rotary valve.

A paper stacking apparatus according to an embodiment of the present disclosure includes a stacking table, a first sensor, and a hardware processor. The stacking table includes an upper face on which papers are stacked, the stacking table being capable of being elevated and lowered by a drive mechanism. The first sensor is disposed at a first position and configured to detect the upper face of the stacking table or an upper face of stacked objects stacked on the stacking table. The hardware processor is coupled to the drive mechanism and the first sensor. The hardware processor is configured to determine that the stacking table is excessively elevated when an elapsed time after starting to detect the object by the first sensor is at least a first excessive-elevation determination value of time.
