A recording medium ejecting device includes ejecting trays, a guiding member and a switching mechanism. The guiding member is switchable between a first posture to permit ejection of a recording medium on one ejecting tray and a second posture to restrict the ejection of the recording medium on the one ejecting tray. The switching mechanism switches the guiding member between the first posture and the second posture. The switching mechanism includes pulleys, a driving belt and a pressing member. The driving belt is wound around the pulleys. The pressing member presses the guiding member. The driving belt includes a contactable area configured to be contactable with each of the pulleys and a contact restricted area whose contact with each of the pulleys is restricted. The pressing member catches the contact restricted area from both an outer face side and an inner face side.

A controller of a printing apparatus is configured to determine whether there is a stack-full tray, restrict discharging of the printing sheet to the stack-full tray and reduce the number of copies made in the sort printing process, store the page number of the page currently printed in association with a stack-full tray, obtain image data corresponding to the page associated with the stack-full tray onwards when it is determined that the full stack status of the stack-full trays is released, and the obtained print images with making the tray of which status is changed from the full status to the non-full status.

A sheet sorting device according to an embodiment includes a transporting unit that transports a sheet. A reading unit generates an image of a surface of the sheet. A decoloring unit performs a decoloring processing to decolor an image on the sheet. The sheet sorting device includes a plurality of sheet stacking trays. A processor causes the reading unit to generate an image of the surface of the sheet after the decoloring unit performs the decoloring processing on the sheet. The processor determines a color of the sheet based on the generated image. The processor determines one sheet stacking tray out of the plurality of sheet stacking trays as a transport destination of the sheet, based on the determined color. The transporting unit transports the sheet to the determined sheet stacking tray.

The present invention provides a medium processing device and medium transaction device that may increase stability by shortening a conveyance path. Namely, a banknote deposit/withdrawal device includes a conveyance section that forms a linear conveyance path along a front-rear direction inside an upper section block, in the vicinity of a boundary with a lower section block. An upper section storage box is disposed in the vicinity of a rear side terminal end of a rear conveyance section. Counterfeit notes are conveyed to the upper section storage box using a switching section. Accordingly, due to keeping the conveyance path length short, the banknote deposit/withdrawal device may reduce the frequency of occurrence of faults, such as banknote jams, and may prevent the circulation of counterfeit notes by storing counterfeit notes segregated from genuine banknotes, reject banknotes, and the like.

A sheet sorting apparatus includes a second tray arranged below a first tray detachable from a main body having a first discharge port corresponding to the first tray and a second discharge port corresponding to the second tray, a discharge unit, a tray detecting unit, and a control unit. The discharge unit discharges a sheet toward the first or second discharge port. In a state that the first tray is detached from the main body and the discharge unit discharges sheets from the first discharge port to the second tray and then the first tray is detected as attached to the main body, the control unit selects a discharge destination of a second sheet, subsequent to a first sheet discharged and stacked first after the first tray is attached to the main body, such that the second sheet is stacked on a tray having the first sheet thereon.

An image forming apparatus includes a main body of the image forming apparatus with an opening portion, an image forming unit, an accommodation portion, a stack portion, a sheet moving unit, and a control unit that controls switching between a first mode that moves, with the sheet moving unit, a sheet accommodated in the accommodation portion and stops the sheet when a part of the sheet is exposed external to the main body of the image forming apparatus from the opening portion, and a second mode that moves the sheet, with the sheet moving unit, accommodated in the accommodation portion and that discharges the sheet to the stack portion.

A mount apparatus to be mounted on a top surface, in a vertical direction, of a main body of an image forming apparatus configured to form an image on a sheet, includes a latch member extending toward the main body from a surface facing the top surface of the main body and being rotatable around a rotational axis extending in a direction along a direction orthogonal to the vertical direction, and a biasing member configured to bias the latch member in a predetermined rotation direction. The latch member is inserted into the main body through an opening that is provided on the top surface of the main body and is engaged with the main body by a biasing force of the biasing member in a state where the mount apparatus is mounted on the main body.

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 conveyor, including: receiving trays; a conveyance mechanism; and a support supporting the trays, wherein at least one tray except a lowermost tray is supported so as to be selectively positioned at one of a receiving position and an upper position, wherein at least one lower tray except an uppermost tray includes a protruding portion attached to a tray body so as to be selectively positioned at one of a protruding position and a retracted position, and wherein the conveyor includes a force transmitting mechanism for effectuating at least one of (a) a retracting movement of the protruding portion of one of the at least one lower tray from the protruding position to the retracted position caused by an upward movement of an adjacent upper tray disposed just above and immediately adjacent to the one of the at least one lower tray from the receiving position to the upper position.

An image forming apparatus includes a main casing including an image forming unit and a discharge tray, and an optional device configured to be removably attached to the main casing. The main casing includes a conveying path through which a sheet is conveyed from the image forming unit, a discharge path through which the sheet is conveyed toward one of the discharge tray and the optional device, the discharge path diverging from the conveying path, and a return path including a first path through which the sheet is conveyed temporarily out of the main casing via an opening formed in the main casing, and a second path through which the sheet is conveyed toward the image forming unit. The first path diverges from the conveying path. The second path diverges from the first path. The optional device is disposed closer to the discharge tray than the opening.
