A sheet feeding device includes a roller pair being mutually non-separable; and a roller pair being mutually separable. The sheet feeding device temporarily stops a sheet in a registration position of the non-separable roller pair and then resumes feeding the sheet. The sheet feeding device feeds sheets such that a following sheet reaches the registration position from the separable roller pair after completion of ejection of a preceding sheet.

A sheet container includes a housing, a stacking part provided in the housing so that recording sheets are stacked on the stacking part, a contact part to be brought into contact with edges of the recording sheets in a length direction on the stacking part in an attached state in which the contact part is attached into the housing, a connection member connected to the stacking part or the housing and having an extension part longer than the stacking part in the length direction, and a retreater that retreats the contact part in the attached state from the extension part with the connection member connected to the stacking part or the housing.

The sheet feeding cassette includes a cassette frame, a first lift plate and a second lift plate. The cassette frame includes a bottom plate and side plates extending in the feeding direction. The bottom plate and the side plates form a sheet placement space. The first lift plate is disposed on the bottom plate, configured to rotate up and down around a first axis extending along a width direction perpendicular to the feeding direction, and configured to lift a leading end portion in the feeding direction of the sheet. The second lift plate is configured to rotate up and down around a second axis extending along the feeding direction and to lift a side end portion along the feeding direction of the sheet.

A handling system (100) for handling stackable flat elements, in particular carton elements. The system (100) includes a supporting table (102) on which at least an edge portion (303) of a stack (101) of flat elements is supportable, a clamping device (103) configured for clamping a first part (113) of the edge portion of the stack (101) to the supporting table (102), and a lifting device (104) configured for lifting a second part (114) of the stack (101) from the supporting table (102). The lifting device (104) and the clamping device (103) are arranged to the supporting table (102) such that the stack (101) is bendable by clamping the first part (113) of the stack (101) onto the supporting table (102) by the clamping device (103) and lifting the second part (114) of the stack (101) from the supporting table (102) by the lifting device (104) at the same time such that the stack (101) is bent around a bending axis (109), wherein the bending axis (109) extends within a plane parallel to a supporting plane (112) of the supporting surface (111).

A media tray may include a number of mezzanines to accumulate media as the media is ejected from a printing device and a number of ramps to selectively engage with a leading edge of the media as the media is accumulated based on a plurality of positions of the number of ramps, the number of ramps positionable based on movement of the number of mezzanines. In one example, movement of the number of mezzanines from a first position to a second position may cause the number of ramps to be in a position to selectively engage and disengage with a leading edge of the media.

A medium feeding device includes: a medium mounting section that a medium is mounted; a feeding unit that feeds the medium in a feeding direction; a separation unit that separates the medium with the feeding unit; an operation detection unit that is disposed at a position facing a surface of the medium in the medium mounting section and detects a movement of the medium in the feeding direction; an interval forming unit that forms an interval in the feeding direction between a trailing end of a first medium which is the lowest medium fed among media mounted on the medium mounting section and a trailing end of a second medium which is bound with the first medium and stacked on the first medium; and a control unit that stops feeding of the medium based on a detection interval by a detection value of the operation detection unit.

A sheet feeding apparatus includes a stacking member having a separation unit and an opening portion disposed upstream from the separation unit, a feeding member, and a moving device that includes a slope portion having a slope along which sheets are guided toward the separation unit. The moving device moves the stacking member between a first position where the feeding member and sheets stacked on the stacking member are in contact with each other, and a second position where the feeding member and the sheets are not in contact with each other. When the stacking member is at the first position, the slope portion is disposed at a position lower than the separation unit in a vertical direction. When the stacking member is at the second position, the slope portion is disposed to protrude via the opening portion to be higher than a stacking surface of the stacking member.

A printer extension kit that modifies a printer to receive and output longer pieces of paper. The printer extension kit includes an input extension part, an output extension part, and an output extension clip. The paper tray of a printer is extended by the input extension part allowing the printer to hold longer pieces of paper. The input extension part is attached to the paper tray of a printer. The output extension part allows a printer to output longer pieces of paper. In more detail, the output extension part prevents longer pieces of paper from falling of the catch tray of a printer. The output extension part is attached into the catch tray of a printer. The output extension clip provides another means for a printer to output longer pieces of paper. In more detail, the output extension clip is attached along the output paper catch of a printer.

A sheet feed device includes a housing, a tray, a feed roller, an arm, a pad, and a protruding portion. The housing has a sheet conveyance path. The tray includes a bottom plate having a sheet support surface that supports a sheet. The sheet conveyance path extends upward from the sheet support surface. The feed roller rotates about a rotational axis and feeds the sheet supported on the sheet support surface in a first direction. The arm rotatably supports the feed roller. The arm swingably moves about an axis parallel to the rotational axis of the feed roller. The pad is disposed on the bottom plate. The pad has a higher friction coefficient than a friction coefficient of the sheet support surface. The protruding portion protrudes upward from the sheet support surface at a position shifted from the pad in a second direction opposite from the first direction.

A sheet transport device includes a sheet load tray on which a sheet is loaded, a detector that detects whether or not the sheet exists on the sheet load tray, a feeder that feeds the sheet one-by-one from the sheet load tray, and a sheet-load-tray ascend-descend unit that moves the sheet in a sheet loading direction to set an uppermost sheet at a sheet feed position of the feeder, and a controller. In a case where the sheet is detected by the detector, the controller causes the sheet load tray to ascend or descend before the feeder starts to feed the sheet so that ascending-descending operation for moving the sheet load tray between the sheet feed position and a descent position located below the sheet feed position is performed at least once.
