The transport element is deflected over the deflecting elements. The second drive unit displaces at least one of the first and second deflecting elements along its axis of rotation so that by displacing the one of the first and second deflecting elements the note of value contacting the at least one transport element is moved obliquely to the transport direction.

A post-processing apparatus performs post-processing on a paper sheet conveyed from a previous stage side, and includes: a corrector that performs bend correction on the paper sheet, in accordance with one of a plurality of bend correction methods; a post-processor that performs the post-processing on the paper sheet subjected to the bend correction performed by the corrector; and a hardware processor that selects one of the plurality of bend correction methods, on the basis of a bend correction accuracy corresponding to a product to be created by the post-processing being performed by the post-processor, and a productivity of the product, wherein from the plurality of bend correction methods, the hardware processor selects a bend correction method that reduces a difference between a post-processing time required for the post-processor to perform the post-processing and a correction time required for the corrector to perform the bend correction on the paper sheet.

A paper feeding mechanism includes a feeding path, a driving motor, a bidirectional transmission mechanism, at least one feeding roller, a unidirectional transmission mechanism and at least one blocking roller. The driving motor is controllable to output a driving force towards a forward direction or a driving force towards a reverse direction. The bidirectional transmission mechanism is connected to the driving motor. The at least one feeding roller is mounted in the feeding path. The at least one feeding roller is connected to the bidirectional transmission mechanism. The unidirectional transmission mechanism is connected to the driving motor. The at least one blocking roller is mounted in the feeding path. The at least one blocking roller is disposed to a downstream of the at least one feeding roller. The at least one blocking roller is connected to the unidirectional transmission mechanism.

A printer includes a curved path through which a medium is transported toward a line head, a transport roller pair provided in the curved path, pinching the medium by a driving roller and a driven roller at a pinching position, and transporting the medium, a gate portion having a contact surface configured to switch between a contact position located upstream of the pinching position in a transport direction in the curved path and a retreat position at which the contact surface does not contact with the medium, and a guide portion guiding a tip of the transported medium to the contact surface located at the contact position.

A sheet conveyance device includes a conveyance roller pair. A skew correction roller pair conveys the sheet after contacting two nip portions, and a sheet skew is corrected in a state in which the skew correction roller pair is being stopped. The sheet having a toner image is bent by a first conveyance guide such that a sheet first surface becomes an inside surface. The sheet is bent by the first and second conveyance guides to cause the sheet first surface to be the inside surface and a sheet second surface to be an outside surface. The skew correction roller pair includes two first rotary members of a first roller. A second roller and the two first rotary members form the two nip portions. The second roller and the first conveyance guide contact the sheet first surface. The first roller and the second conveyance guide contact the sheet second surface.

The present invention provides a conveyor mechanism for conveying sheets. The conveyor mechanism comprises a movable conveyor body, a drive mechanism, and an adjustment system configured to detect and correct skewing of the conveyor body, comprising one or more markers provided on or in the conveyor body, a sensor arrangement for detecting each marker at two or more discrete positions, and a processor to determine the skewing of the conveyor body. The conveyor body and the drive mechanism of the conveyor mechanism are mounted on a movable conveyor frame, and the adjustment system includes a frame shifting device comprising one or one or more actuator for shifting or moving the conveyor frame relative to a fixed framework. The invention also provides a related method of correcting skewing in a conveyor mechanism for conveying sheets along a transport path.

A sheet conveying device includes a sheet skew corrector to correct a skew of a leading end of a sheet inclining from a sheet conveyance direction and a pair of registration rollers disposed upstream of the sheet skew corrector in the sheet conveyance direction. The pair of registration rollers freely contacts and separates from each other. The pair of registration rollers conveys the sheet downstream of the sheet skew corrector in the sheet conveyance direction when driven at a prescribed time. A pair of conveyance rollers is placed upstream of the pair of registration rollers in the sheet conveyance direction. The pair of conveyance rollers continuously sandwiches the sheet from when the sheet with the skew corrected is sandwiched by the pair of registration rollers to when a trailing end of the sheet passes between the pair of conveyance rollers.

A sheet conveying device includes a sheet detection unit and a position adjusting mechanism. The position adjusting mechanism is disposed on a downstream side of the sheet detection unit in a sheet conveying direction in the sheet conveying path, includes an adjusting roller pair, and performs skew correction and positional displacement correction of a sheet, while conveying the sheet. The sheet conveying path includes a first conveying roller pair disposed on an upstream side of the position adjusting mechanism in the sheet conveying direction, and a curved part disposed between the adjusting roller pair and the first conveying roller pair, which curves in an S shape so as to be convex in a front and back side direction of the sheet alternately at different positions in the sheet conveying direction. The adjusting roller pair nips and conveys the sheet together with the first conveying roller pair.
