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.

In the invention described, an actuating solenoid on one side of a printer wall connects to a pawl by a lever component. The lever has a pawl-actuating post extending through a wall window so that it may interface with a flared slot on the clutch's pawl. By extending the post through the wall window, space is saved when the printer door is closed because the solenoid does not need to be on the inside of the wall.

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.

Techniques are described herein for reducing bowing effects on a substrate while the substrate is being transported, for example in an elevator mechanism, from a first travel path to a second travel path, where the first travel path is offset from the second travel path so that the first travel path is not collinear with the second travel path. The substrate can be any substrate that is bowed and for which one wishes to eliminate or reduce the bow. One specific substrate that can benefit from the techniques described herein are personalized documents such as plastic cards including but not limited to financial (e.g. credit and debit) cards, drivers' licenses, national identification cards, gift cards, loyalty cards, employee badges, and other plastic cards which bear personalized data unique to the card holder and/or which bear other card or document information.

A diverting system is proposed for diverting boxes from normal production flow. One embodiment comprises a diverter with a diverter surface, a diverter cam in contact with the diverter, a diverter cam shaft connected to the top diverter cam such that rotation of the diverter cam shaft causes rotation of the diverter cam, and an electric motor connected to the diverter cam shaft and configured to rotate the diverter cam shaft. The diverter cam is configured to control position of the diverter as the diverter cam rotates such that rotation of the diverter cam causes the diverter surface to move from a position above normal production flow to a diverting position within the normal production flow.

A sheet conveying apparatus for conveying a sheet in a conveying direction includes a pair of conveying rollers receiving and conveying a sheet; an endless conveying belt conveying the sheet; a plurality of balls to be rotatable in any direction while nipping the sheet with the conveying surface; a pair of regulating guides disposed on both sides of the conveying belt; a guide moving unit that moves the pair of regulating guides; and a roller moving unit that moves at least one of the pair of conveying rollers to a nip position and a nip release position. Before a rear end of the sheet passes the pair of conveying rollers, the pair of conveying rollers is moved to the nip release position by the roller moving unit, and then, the guide moving unit makes each of the pair of regulating guides reach the guide position from the retracting position.

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 jam removal structure can include a transporting roller transporting a print medium along a transporting path, an Inner-side guide, and first and second guides facing the inner-side guide to form the transporting path and located in an upstream side and a downstream side of the transporting roller based on a transport direction of the print medium to be rotatable to an open position opening the transporting path and a path formation position forming the transporting path. The example jam removal structure can include an operating lever connected to each of the first and second guides by first and second connecting members to switch the first and second guides to the open position or the path formation position and an elastic member applying an elastic force to the first and second guides in a direction rotating toward the path formation position.

A sheet conveyer, including a body with a conveyer path, a first roller, a second roller, a roller holder supporting the second roller rotatably, an urging member urging the roller holder, and a guide member, is provided. The guide member is supported rotatably by the body at a position on a side opposite to the first roller across the second roller is pivotable between a closed position and an open position. The roller holder is movable between a first position, where the second roller contacts the first roller, and a second position, where the second roller is separated from the first roller and in which the roller holder contacts the guide member located at the open position. The roller holder located at the second position is restricted by the guide member from moving farther from the first position. The urging member urges the roller holder toward the first position.

A sheet feeding device includes a casing; a door rotatable relative to the casing; a tray configured to stack a sheet thereon and rotatable between a closed position where the tray is closed to the casing, a first open position where the tray opens relative to the casing at a first angle, and a second open position where the tray opens relative to the casing at a second angle larger than the first angle; and a sheet feeding unit provided in the casing and configured to feed the sheet stacked on the tray being in the first position. When the door is opened relative to the casing at an angle exceeding the first angle in a state in which the tray is in the first open position, the door moves the tray to the second open position.
