A relay transport device is configured to relay a medium fed from the feeding device and transport the medium to the recording device. The relay transport device includes a first restriction section having a first restriction surface configured to position a first edge, which is one edge in a width direction, a first transport belt configured to transport the medium toward the first restriction surface in a first direction, which intersects the transport direction and the width direction, a second transport belt that is provided downstream of the first transport belt in the transport direction and that is configured to transport the medium toward the first restriction surface in a second direction, which intersects the transport direction and the width direction, and a suction section configured to suck the medium via a through hole provided in the first transport belt and the second transport belt.

A tape applicator configured for applying a tape to a carton (e.g., for sealing and/or assembling the carton). The tape applicator may include an edge folder assembly having an edge folder roller operatively coupled to a support member that allows the edge folder roller to rotate around the support member. The edge folder assembly may also include an alignment assembly (e.g., a self-alignment assembly) that allows the edge folder roller to move axially along the support member. The alignment assembly may comprise one or more biasing members (e.g., springs, or the like) and/or one or more restraining members (e.g., washers, or the like) to aid in allowing the edge folder roller to rotate and/or move axially with respect to the one or more support members in order to account for shifting of the tape transversely through the tape applicator.

A medium conveying apparatus for conveying media in a conveying direction includes: a medium container on which the media are stacked; and a medium separator that abuts an uppermost medium of the media stacked on the medium container and separates the uppermost medium from the media stacked on the medium container. The medium container includes: a medium support that abuts a lowermost medium of the media stacked on the medium container and supports the stacked media; and a tilting mechanism that tilts the medium support relative to a horizontal plane at a tilt angle according to a weight of the media stacked on the medium container.

A sheet processing apparatus includes a conveying portion, a stack portion on which sheets conveyed by the conveying portion are stacked, a first regulating portion regulating a position of a sheet bundle stacked on the stack portion in a crossing direction, a second regulating portion regulating a position of a sheet bundle on the stack portion in a conveying direction, a first binding device moved in the crossing direction and binding a corner portion of a sheet bundle by a staple, a second binding device binding a corner portion of a sheet bundle without a staple, and a controller positioning the first binding device and binding a corner portion of a sheet bundle by the first binding device. The controller also moves the second binding device and binds a corner portion of a sheet bundle without a staple by the second binding device.

An image forming apparatus configured to form images on both sides of a sheet, includes an image forming unit, which is configured to form an image on an image bearing member, and a sheet conveying device, which is configured to move the sheet being conveyed toward a width direction, which is orthogonal to a conveyance direction. After the formed image is transferred onto a first surface of the sheet, the image forming apparatus inverts and conveys the sheet to transfer an image onto a second surface. Moreover, a side edge position of the sheet in the width direction is detected during conveyance for the transferring onto each of the first surface and the second surface, and an image writing start position for the image forming unit is determined based on a result of the detection to store a result of the determination in a memory.

A pinch roller mechanism includes a rail, a slider, a roller bracket, a spring, and a pinch roller. The rail extends in a first direction crossing the conveyance direction of a medium while being apart from a medium driving roller configured to convey the medium. The slider is supported by the rail to be movable along the rail. The roller bracket is supported by the slider to be movable with respect to the medium driving roller. The spring is provided between the slider and the roller bracket and biases the roller bracket toward the medium driving roller. The pinch roller is rotatably supported by the roller bracket while setting the axial direction in the first direction.

A sheet conveying device, which is included in an image forming apparatus, includes a sheet holding roller to move while holding a sheet, a detector to perform a primary detection to detect a sheet position before the sheet holding roller holds the sheet and a secondary detection to detect a sheet position downstream from the sheet position detected by the primary detection, and a controller configured to cause the sheet holding roller to perform a first drive to move the sheet holding roller in at least one direction of a width direction of the sheet and a rotation direction in a sheet conveying surface based on a result of the primary detection and a second drive to move the sheet holding roller opposite to the at least one direction of the first drive, based on a result of the secondary detection.

A sheet conveying device, which is incorporated in an image forming apparatus, includes a first detector to detect an angle deviation of a recording medium to a sheet conveying direction, a second detector to detect a lateral shift of the recording medium to a width direction, a third detector to detect at least one of the angle deviation and the lateral shift after correction of the angle deviation detected by the first detector and the lateral shift detected by the second detector, and a rotary body to perform a primary movement by (1) rotating in the sheet conveying direction and returning to a reference position and by (2) moving in the width direction and returning to the reference position, and a secondary movement by performing at least one of (1) and (2) after the primary movement.

An image forming apparatus includes a control portion configured to control, based on a detection position of a sheet in a width direction, in a case where a center of an image formed on a first surface at an image forming portion in the width direction is displaced from a center of the sheet in the width direction at the image forming position and an image is to be formed on a second surface of the sheet, a moving portion to move the sheet in the width direction such that a position of the center of the sheet on a conveyance path in the width direction at the sheet forming position when the image is formed on the first surface and a position of a center of the sheet on the conveyance path in the width direction at the sheet forming position when the image is formed on the second surface coincide.

A registration system for a printing device and a method for controlling the same are disclosed. For example, the registration system includes at least one sensor, omni wheels, a motor coupled to each omni wheel, a translating carriage, and a processor communicatively coupled to the at least one sensor, the motors, and the translating carriage, wherein the processor calculates a desired movement to move the omni wheels and the translating carriage based on the position of the print media.
