A conveyance device includes a tray on an upper surface of the conveyance device and an upper guide below the tray. The tray receives a sheet, and the upper guide defines a conveyance path in which the sheet is conveyed. The upper guide is movable together with the tray to open the conveyance path.

A processing system includes a processing apparatus, a feeding apparatus, an ejection apparatus, and circuitry. The processing apparatus includes a processing device to execute a process on each of objects including a first object and a second object. The feeding apparatus feeds the objects to the processing apparatus. The ejection apparatus ejects the objects sent from the processing apparatus. The ejection apparatus includes an ejection purge portion to receive the second object traveling in the ejection apparatus. The circuitry sets whether to permit ejection of the second object not jammed to the ejection purge portion in case of a jam of the first object in the processing system. The circuitry causes the second object to be ejected to the set ejection purge portion, in response to detection of the jam of the first object.

According to one embodiment, an image processing apparatus includes an apparatus main body, a first rotating body, a second rotating body, and a connection member. The first rotating body is configured to be openable and closeable and provided in the apparatus main body. The second rotating body is provided in the first rotating body. The second rotating body is configured to be openable and closable from the first rotating body in the same direction as that of the first rotating body. The connection member is linear. The connection member is configured to connect the apparatus main body and the second rotating body to each other and to restrict a rotation angle of the second rotating body.

An image forming system includes a detection unit to detect a recording material, having an image formed thereon by an image forming unit, placed on a processing tray, a staple unit, a discharge unit, and a discharge tray. A first mode of the system is to discharge the recording material conveyed from the image forming unit to the discharge tray via the processing tray and a second mode involves waiting for instruction for executing. When the detection unit detects the recording material inserted into the processing tray in the second mode, and a recording material first mode conveying instruction is issued in a state of waiting for the executing instruction after the recording material detection, a discharge operation is performed to discharge the recording material inserted into the processing tray to the discharge tray without the staple unit executing staple processing on the recording material inserted into the processing tray.

A sheet alignment apparatus includes a supporting portion configured to support a sheet, a first alignment member configured to abut an end portion in a first direction of the sheet supported by the supporting portion and align a position of the sheet in the first direction, a first moving unit configured to move the first alignment member in the first direction, a second alignment member configured to abut an end portion in a second direction of the sheet supported by the supporting portion and align a position of the sheet in the second direction, the second direction being perpendicular to the first direction, and a second moving unit configured to move the second alignment member in the second direction, wherein the first moving unit is disposed below the supporting portion, and wherein the second moving unit is disposed above the supporting portion.

A medium transport apparatus includes a first and a second transport path, a third transport path formed the first transport path and the second transport path merging at a merging point, a door that is displaceable between a closed state in which the door forms at least a portion of the first transport path and an opened state in which at least a portion of the first transport path is opened, and a switching section that is arranged at the merging point and that is, while the door is in the closed state, displaceable between a first state in which the second transport path is opened and a second state in which the first transport path is opened, wherein when the door is in the opened state, the switching section is displaced to a third state in which at least a portion of the second transport path is opened.

A rotating device includes: an opening-closing portion supported so as to be openable and closable with respect to a support body; a drive unit provided on the support body; a first rotating body provided on the support body and rotated by a drive force of the drive unit; a driven portion provided in the opening-closing portion; a second rotating body provided in the opening-closing portion, rotated by a transmitted rotational force, and transmitting the rotational force to the driven portion; and an annular body formed in an annular shape, wound around the first rotating body and the second rotating body, maintaining the winding state in both an open state and a closed state of the opening-closing portion, and transmitting the rotational force of the first rotating body to the second rotating body.

A sheet conveyance apparatus includes a first guide to guide a conveyed sheet and a second guide to face the first guide and to form a sheet conveyance path together with the first guide, with the second guide being pivotable between a first position in which the sheet conveyance path is formed and a second position in which the sheet conveyance path is opened. A cover is movable between a closed position in which it covers the second guide and an open position in which the second guide is manipulatable, and an abutting portion is provided on the cover to abut the second guide. In a state where the second guide is held at the second position by the holding portion and the cover moves to the closed position from the open position, the abutting portion abuts the second guide to release the second guide held by the holding portion.

A sheet folding device includes a sheet conveyance path, a first folding conveyance path, a first folding roller pair, a first folding guide, and a conveyance roller. The first folding roller pair is composed of a first roller and a second roller forming a first folding nip by being brought into pressure contact with an upstream side of the first roller. The first folding guide is movable between a folding position at which it approaches the first folding nip, guiding a to-be-folded part of a sheet to the first folding nip, and a retracted position at which it is away from the first folding nip. The conveyance roller forms, together with the second roller, a first assist roller pair that conveys the sheet along the sheet conveyance path. The first folding guide has a pivot fulcrum on a downstream side relative to the first folding nip in the conveyance direction.

An image forming system includes a detection unit to detect a recording material, having an image formed thereon by an image forming unit, placed on a processing tray, a staple unit, a discharge unit, and a discharge tray. A first mode of the system is to discharge the recording material conveyed from the image forming unit to the discharge tray via the processing tray and a second mode involves waiting for instruction for executing. When the detection unit detects the recording material inserted into the processing tray in the second mode, and a recording material first mode conveying instruction is issued in a state of waiting for the executing instruction after the recording material detection, a discharge operation is performed to discharge the recording material inserted into the processing tray to the discharge tray without the staple unit executing staple processing on the recording material inserted into the processing tray.
