A stacking device for generating decks (10) of sheet elements (12) comprises a transport device with an upper side onto which sheet elements (12) are arranged on separate sheet sections (50). Each sheet section (50) is adapted to transport at least one sheet element (12). The upper side has a height offset between adjacent sheet sections (50). A displacement element shifts sheet elements (12) of one sheet section (50) onto an adjacent sheet section (50) in order to produce the deck (10) of sheet elements (12).

A cassette comprises a housing portion configured to have a placement face on which sheets are placed and to house sheets; and a standing wall configured to constitute a portion of the housing portion, and to regulate sheets on a back end side in a conveyance direction of sheets to be conveyed from the placement face to a printing apparatus, wherein the standing wall includes a protrusion that protrudes toward the placement face at a position above a predetermined position, which is at a height of sheets that can be stacked on the placement face.

A container member includes a container body that contains a recording medium and that tilts such that a leading edge of the contained recording medium is higher than a trailing edge, and a leading edge restriction portion that comes into contact with a portion of the leading edge except for at least a first end portion and that restricts a position of the leading edge.

A sheet feeding device includes a sheet stacking unit, a long sheet stacking unit, a first guide, a first detector, and a closing unit. The sheet stacking unit is movable up and down. Sheets are stacked on the sheet stacking unit. The long sheet stacking unit is detachably mounted on the sheet stacking unit. Long sheets are stacked on the long sheet stacking unit. The first guide is movable along a feeding direction through a groove. The first guide is deformable into a shape that does not interfere with the long sheet stacking unit. The first guide guides a rear end portion of the sheets in the feeding direction. The first detector is provided in the first guide. The first detector detects the sheets stacked on the sheet stacking unit. The closing unit is detachably attached to the groove in the sheet stacking unit. The closing unit closes the groove.

A supply device configured to supply a medium to a processing unit configured to perform processing on the medium, the supply device including an accommodating unit configured to accommodate a plurality of the media in a state of being stacked therein and a vibration imparting unit configured to contact ends of the plurality of media accommodated in the accommodating unit to impart vibration to the medium.

According to one embodiment, a sheet conveying device includes a tray and a correcting member. On the tray, a sheet bundle in which a plurality of sheets are overlapped is stacked in a thickness direction of the sheet bundle. The correcting member moves relative to the tray in the thickness direction. The correcting member abuts against an upper layer portion of an outer peripheral portion of the sheet bundle on the tray, and presses the upper layer portion from an outside after abutting. The correcting member corrects a position of the upper layer portion in a lateral direction intersecting the thickness direction toward an inside from the outside of the sheet bundle.

Provided is a multi-banknote cassette with a movable stopper, which is capable of storing various kinds of banknotes at the same time. The multi-banknote cassette includes a movable stopper which is installed in a stack guide for guiding banknotes introduced into a cassette body of the banknote cassette toward a banknote stopper, and rotated to protrude from or retreat into a transfer path of the banknotes. When a banknote having a relatively small size among the banknotes inserted into the banknote cassette is introduced, the movable stopper is rotated to protrude from the stack guide and regulates the front end of the introduced banknote, and when a banknote having a relatively large size is introduced, the movable stopper is rotated to retreat into the stack guide, and a banknote stopper installed at the rear of the stack guide regulates the front end of the introduced bank.

A supply device configured to supply a medium to a processing unit configured to perform processing on the medium, the supply device including an accommodating unit configured to accommodate a plurality of the media in a state of being stacked therein and a vibration imparting unit configured to contact ends of the plurality of media accommodated in the accommodating unit to impart vibration to the medium.

Example printer finishing apparatus are described herein. An example printer disclosed herein includes an alignment guide, a track to align a sheet relative to the alignment guide, a clamp to move between a raised position and a lowered position relative to the sheet, and a force applicator coupled to the clamp. The force applicator is to cause the sheet to engage the alignment guide when the clamp is in the lowered position.

An attachment is attachable to and detachable from a sheet stacking board. The attachment includes an end fence configured to restrict a position of a trailing end of a sheet in a conveying direction. The end fence includes a facing surface facing the trailing end of the sheet. The facing surface includes an inclined surface inclined with respect to a vertical direction of a stacking surface on which the sheet is stacked, such that a higher part of the facing surface is located more upstream in the sheet conveying direction.
