A discharge extension tray can be extended in a sheet discharge direction from a discharge tray. A front end regulating portion is coupled to the discharge extension tray on a downstream side in the sheet discharge direction of the discharge extension tray such that the front and regulating portion is turnable with respect to the discharge extension tray. A sheet guide portion guides a front end portion of the sheet to a direction separating from a turning center of the front end regulating portion when a sheet having a length longer than a predetermined size is discharged in a state where the discharge extension tray is not extended from the discharge tray.

A sheet discharge apparatus includes a main tray, a discharge unit, and an expansion tray. The main tray is pivotable between a closed position and open position relative to a sheet discharge apparatus main body. The discharge unit discharges the sheet onto the main tray in the closed position. The expansion tray expands a main tray stacking area and is movable between a storage position where the expansion tray is stored in the main tray and an expansion position where the expansion tray is slid from the storage position in a sheet discharge direction and expands the stacking area. At the expansion position, the expansion tray is pivotable independently of the main tray. A direction in which the expansion tray is pivoted upward is the same as a direction in which the main tray is pivoted from the closed to the opened position.

An example disclosed output hopper includes a cavity to receive media units from an output of a media processing device, the cavity to cause the media units to form a stack in a first direction; a first door pivotably movable between a closed position and an open position, the first door to retain the media units in the cavity when in the closed position; a second door movable between the closed position and the open position, the second door to retain the media units in the cavity when in the closed position; wherein the first door is configured to pivot on a first axis substantially parallel to the first direction; and the second door is configured to pivot on a second axis substantially parallel to the first direction.

A conveying apparatus includes: receiving trays arranged vertically and has a lowest tray and a first receiving tray; a conveying mechanism; a supporter supporting the receiving trays; and a swing mechanism configured to swing the first receiving tray with respect to the supporter to one of a receiving position at which the first receiving tray receives a medium and an upper position. The swing mechanism is configured to: keep the first receiving tray at the upper position when a first external force directed in a direction in which the first receiving tray is moved from the upper position toward the receiving position is not applied to the first receiving tray located at the upper position; and swing the first receiving tray with respect to the supporter toward the receiving position when the first external force is applied to the first receiving tray.

A medium discharging device includes a discharging unit which discharges a medium; and a medium receiving tray which receives the medium discharged by the discharging unit, and is switched between an extended state and an accommodated state, in which the medium receiving tray is provided with a base tray, a main extending unit that is accommodated or extended, and at least one sub-extending unit that is accommodated or extended, and in which the base tray forms an accommodating space for accommodating at least the one sub-extending unit, and is provided with a first protrusion portion protruding toward the accommodating space.

A sheet discharge apparatus includes a main tray, a discharge unit, and an expansion tray. The main tray is pivotable between a closed position and open position relative to a sheet discharge apparatus main body. The discharge unit discharges the sheet onto the main tray in the closed position. The expansion tray expands a main tray stacking area and is movable between a storage position where the expansion tray is stored in the main tray and an expansion position where the expansion tray is slid from the storage position in a sheet discharge direction and expands the stacking area. At the expansion position, the expansion tray is pivotable independently of the main tray. A direction in which the expansion tray is pivoted upward is the same as a direction in which the main tray is pivoted from the closed to the opened position.

A sheet feeding device for feeding a sheet includes a support unit, an open-close member rotatably supported between open and closed positions, a slide member supported in a slidably movable manner and including a rotation shaft portion, and a regulation member supported by the slide member. The open-close member supports the sheet in the open position with the support unit. The regulation member regulates a position of the sheet supported by the support unit or the sheet supported by the support unit and the open-close member. The support unit includes a guide portion that movably guides the rotation shaft portion. If the open-close member is rotated from the open position toward the closed position in a state in which the open-close member is in contact with the slide member, the slide member rotates by following movement of the open-close member with respect to the guide member.

The sheet feed device includes a sheet containing cassette with a sheet stacking plate therein, a sheet feed part enabled to feed a sheet within the sheet containing cassette set in a setting position, a first sensing mechanism, a lift mechanism, a drive mechanism, and a controller. The lift mechanism includes a cassette-side coupling member for transmitting driving force to the sheet stacking plate. The drive mechanism includes a main body-side coupling member coupled with the cassette-side coupling member. When the first sensing mechanism has sensed that no sheets are stacked on the sheet stacking plate, the controller makes the main body-side coupling member rotate reverse to move down the sheet stacking plate and, even after the sheet stacking plate lowers, makes the main body-side coupling member continue to be rotated reverse so as to move out the sheet containing cassette from the setting position.

A medium discharging device includes a discharging unit which discharges a medium; and a medium receiving tray which receives the medium discharged by the discharging unit, and is switched between an extended state and an accommodated state, in which the medium receiving tray is provided with a base tray, a main extendeding unit that is accommodated or extended, and at least one sub-extendeding unit that is accommodated or extended, and in which the base tray forms an accommodating space for accommodating at least the one sub-extendeding unit, and is provided with a first protrusion portion protruding toward the accommodating space.

The present invention relates to a stacker module for a folder-gluer machine, the stacker module being located downstream of a transfer module in a direction of transportation of the folder-gluer machine and configured to receive folding boxes from a conveyor in the transfer module. The stacker module comprises a loading surface configured to receive a plurality of folding boxes in order to form a stack and to descend vertically as the number of folding boxes on the loading surface increases, and a linearly movable ejector configured to eject the stack from the loading surface. A front abutment guide configured to move between an abutment and a clearing position to retain and release the stack.
