A sheet transport device includes a transport unit, a load section, and a sheet accommodation section. The transport unit has a transport path along which a sheet read at a read position is transported to an output unit. The sheet output by the output unit is loaded onto the load section. The sheet accommodation section is disposed downstream in an output direction of the sheet from an inner wall surface extending upward adjacent to the load section and has a recess capable of accommodating a sheet of a predetermined minimum size. A retrieval space through which the sheet accommodated in the sheet accommodation section is retrievable is provided by exposing the transport path in a direction opposite to a loading direction of the sheet.

A registration system includes nip rollers for conveying a sheet in a process direction when the nip rollers are in an engaged position, and first and second sets of omnidirectional rollers arranged perpendicularly to each other, for conveying the sheet in the process and cross-process directions, respectively. The omnidirectional rollers each allow the sheet to slide, relative to the omnidirectional roller, in a direction parallel to an axis of rotation of the omnidirectional roller. The nip-rollers are movable from the engaged position to a disengaged position, in which the first pair of omnidirectional rollers convey the sheet in the process direction. A feedback system includes sensors for determining registration errors of the sheet and a control system controls the omnidirectional rollers to reduce the registration errors in the sheet while the nip-rollers are in the disengaged position.

Disclosed is an example of a registration assembly for a media processing device, including a registration surface. The registration assembly including a bias member coupled to the registration surface to bias the registration surface toward the media processing path to apply a force to a media unit. The registration assembly including an activator coupled to a roller, the roller to be driven via contact with the media unit. The activator configured to move the registration surface toward the media processing path into the active position to engage the media unit responsive to rotation of the roller in the first rotational direction. The activator configured to move the registration surface away from the media processing path into an inactive position responsive to rotation of the roller in the second rotational direction.

An apparatus for steering a web, including a web path having at least one steering roller and an exit roller, each having a mount; wherein the steering roller(s) each have an axis of rotation and wherein the mounts for the steering roller(s) can pivot those axes with a total of two degrees of freedom. An array comprising a plurality of sensors for monitoring the position of the web is present connected to a controller so as to determine the position and angular orientation of the web. The controller adjusts the pivot(s) of the mount(s) so as to control the angular orientation and the lateral position of the web at a particular point along the web path.

Provided is an image forming apparatus with rollers capable of coming into contact with or leaving a recording medium, in which meandering of the recording medium is suppressed. The apparatus includes a tension adjuster for adjusting a tension applied to the recording medium nipped between a plurality of roller pairs. The tension adjuster is located upstream of, among the roller pairs, the most upstream roller pair located on the most upstream side in the conveyance path or downstream of, among the roller pairs, the most downstream roller pair located on the most downstream side in the conveyance path and the tension adjuster rotates in the direction of conveyance of the recording medium to adjust the tension of the recording medium.

A printer includes a printing unit having a printing head and a platen positioned opposite the printing head, the printing head being configured to print on a print medium that is fed between the printing head and the platen, a ribbon holding shaft configured to hold an ink ribbon that is wound thereon, a ribbon winding shaft configured to wind and collect the ink ribbon supplied from the ribbon holding shaft, and first and second guide shafts provided along a feeding route of the ink ribbon between the ribbon holding shaft and the ribbon winding shaft to apply tension to the ink ribbon. At least one of the first and second guide shafts has a tilt adjuster that applies a twist to the ink ribbon in a width direction of the ink ribbon through said at least one of the first and second guide shafts.

A media processing device includes: a transport assembly to guide a media unit from a source past a processing head in an outbound direction, and past the processing head in a return direction toward an output; and a redirector to receive the media unit in the outbound direction, flip the media unit, and expel the media unit in the return direction. The redirector includes: a motor having an output shaft; a carriage rotatably supported by a housing; a roller supported by the carriage for engaging with the media unit; and a selector connected between the output shaft and the roller. The selector, for a first output shaft drive direction, rotates relative to the carriage and drives the roller for receiving or expelling the media unit, and for a second output shaft drive direction, engages the carriage and rotates the carriage relative to the housing for flipping the media unit.

A conveyance mechanism includes a lower conveyance guide below an inclined conveyance path having upward or downward inclinations with which a sheet material is to be conveyed, that guides a lower surface of the sheet material; an upper conveyance guide above the inclined conveyance path, that guides an upper surface of the sheet-shaped material, the upper conveyance guide being openable and closable about a rotation shaft, which is on a side of the inclined conveyance path in a direction of a width of the inclined conveyance path to extend along the inclined conveyance path; and a first urging member to urge a portion of the upper conveyance guide away from the rotation shaft in the direction of the width of the inclined conveyance path toward the rotation shaft, the portion of the upper conveyance guide being at an upper end of the upper conveyance guide in an inclined direction.

The invention relates to a device (30) for separating at least two strands of material (12a, 12b) from the cutting of a strip of material moving continuously, characterized in that the device includes a spreader (32, 33) for spreading the strands of material apart in a transverse direction (v) extending in the movement plane (P2) of the strands of material, perpendicularly to the movement direction of said strands of material.

A sheet transport apparatus according to an embodiment includes a roller having a surface formed from an elastic material. The roller transports a sheet. A rotation mechanism rotated the roller around an axis of the roller. A twist mechanism selectively twists the roller with respect to the axis. When the roller is twisted and the rotation mechanism rotates the roller, a sheet transported by the roller is transported in a first direction perpendicular to the axis and in a second direction parallel to the axis. When the roller is not twisted and the rotation mechanism rotates the roller, a sheet transported by the roller is transported in the first direction and not in the second direction.
