The apparatus may also include a custom position pawl movably engaged with the guide frame, the custom position pawl to engage custom pawl teeth of a rack. The apparatus may further include a switch in movable engagement with the guide frame, the switch being movable between a first position at which the custom position pawl is maintained at a disengaged position with respect to the custom pawl teeth of the rack and a second position at which the custom position pawl is free to move between the disengaged position and an engaged position with respect to the custom pawl teeth of the rack.

A sheet feeding apparatus includes a sheet storing tray for loading sheets, an apparatus main body to which the sheet storing tray is slidably attached, and a restriction mechanism that restricts a position of the sheet storing tray. The restriction mechanism includes an engagement portion provided in the apparatus main body and a stopper member that is provided in the sheet storing tray and engages with the engagement portion. The stopper member is configured so as to be movable in a crossing direction crossing a direction in which the sheet storing tray slides and determines a position in the crossing direction of the sheet storing tray with respect to the apparatus main body.

A banknote pay-out device includes a pay-out port where a banknote bundle is handed over to a user, a shutter that is provided so as to capable of closing or opening the pay-out port, a gripping conveyance guide and a stage that guide the banknote bundle W, and a push-out plate that is disposed facing the gripping conveyance guide and the stage, and that moves in a handover direction toward the pay-out port while contacting one edge side of the banknote bundle to convey the banknote bundle toward the pay-out port. The banknote pay-out device also includes a shutter opening-and-closing projection that, as the push-out plate moves toward the pay-out port, moves together with the push-out plate and moves the shutter toward an opening direction to open the pay-out port.

A medium conveyance device is provided including a placement body, a Scott-Russell body, a moving section, and a conveyance state switching section. The placement body includes a bundle conveyance face on which a medium bundle configured by stacking plural medium into a bundle shape is conveyed in a state placed on the bundle conveyance face. The Scott-Russell body includes an abutting portion that abuts the medium bundle. The movement section causes at least a portion of the Scott-Russell body to abut against the medium bundle and moves the Scott-Russell body along the bundle conveyance face in a first direction, or in a second direction opposite to the first direction, so as to move the medium bundle along the bundle conveyance face in the first direction or in the second direction. The conveyance state switching section utilizes the Scott-Russell body being moved by the movement section to switch to a first conveyance state in which at least a portion of the Scott-Russell body is caused to abut against the second direction side of the medium bundle and conveyance of the medium bundle toward the first direction is enabled, or to a second conveyance state in which at least a portion of the Scott-Russell body is caused to abut against the first direction side of the medium bundle and conveyance of the medium bundle toward the second direction is enabled.

A cassette in which sheets are stacked is electable from an apparatus main body. An intermediate plate is provided in the cassette that is movable to raise and lower the stacked sheets. A securing member that restricts the cassette from being raised when at a restricted position is provided, where, in response to movement of ejecting the stacking unit from the apparatus main body, the securing member moves to a permitted position that enables the movable member to rise.

Some examples of a document scanning system can include a scanner and a sheet output stacker. The stacker includes an upper surface configured to mate with the scanner configured to scan and transfer contents of a paper document. The stacker is configured to receive paper sheets from the scanner. The stacker includes multiple, upward extending interface housings positioned on the upper surface. The multiple interface housings are configured to be received in respective multiple receiving structures in the scanner, and are configured to mechanically and electrically couple the sheet output stacker and the scanner. The interface housings allow care-free electrical and mechanical pairing of a scanner to a stacker with no tools or adjustments. Simply positioning the scanner on the stacker such that the interface housings are aligned with the receiving structures results in the scanner being automatically guided into place and connected to the stacker through gravity.

A medium conveying apparatus includes an imaging device to image a medium and configured to move in a moving direction, a roller configured to move in the moving direction, on an upstream side of the imaging device, a conveyance guide provided with the imaging device to move the imaging device, wherein the conveyance guide includes a slope for coming into contact with the medium, an engaging member provided with the imaging device to move the imaging device, and a moving member to move the imaging device by engaging with the engaging member in conjunction with a movement of the roller. The engaging member and the moving member are configured to be separated at a distance from one another when the medium is not conveyed. The moving member moves the imaging device by engaging with the engaging member only when the medium has a thickness greater than the distance.

An image processing apparatus includes an apparatus body, a feeding cassette, a pin member, a lever, an elastic member, and a guide mechanism. The feeding cassette is insertable into and ejectable from the apparatus body in one direction and includes an insertion position for insertion into the apparatus body and an ejection position for ejection from the apparatus body. The pin member is connected to the feeding cassette. The lever is rotatable around an axis in a first direction, and includes a pin engagement portion engaging with the pin member at a tip end in the axial direction. The elastic member includes a tip end connected between the rotation axis of the lever and the pin engagement portion of the lever, and adds a force for rotation in an insertion direction. The guide mechanism shortens a distance between the pin member and the rotation axis of the lever.

A sheet feeding device having sheet feed tray configured to support multiple sheets be movably inserted to a main body. A sheet feed roller is configured to contact the sheet supported by the sheet feed tray and rotate to apply a feeding force to feed the sheet in a sheet feed direction. The sheet feed roller is configured to contact the sheet feed tray when there is no sheet on the sheet feed tray. A push latch mechanism is arranged on a downstream side with respect to the sheet feed roller in the sheet feed direction. A state of the push latch mechanism is alternately switched between an engaged state and a disengaged state every time when a pressing force is applied to the push latch mechanism. A first spring is configured to exert an elastic force to move the sheet feed tray toward a near side.

A sheet feeding device includes a sheet feeding cartridge, a pair of fixed rails, a pair of movable rails and a pressing part. The sheet feeding cartridge has a pair of side plates extending in taking-out/taking-in directions and is taken out/in an installed part in an apparatus main body. The fixed rails are extended in the taking-out/taking-in directions in the installed part. The movable rails are provided to move in the taking-out/taking-in directions along the fixed rails. If the pressing part is provided in one side plate, the pressing part applies biasing force to one movable rail facing to one side plate so that another side plate comes into pressure contact with another movable rail. If the pressing part is provided in one movable rail, the pressing part applies biasing force to one side plate so that another side plate comes into pressure contact with another movable rail.
