A foldable baffle structure is mounted to a tray of a scanner or a printer. The foldable baffle structure includes two limiting components mounted to the tray. Each limiting component includes a sliding element, a stopping element, a guiding element and a pivoting element. Middles of the two sliding elements of the two limiting components have two accommodating spaces penetrating through top surfaces and bottom surfaces of the two sliding elements. The two stopping elements of the two limiting components are mounted in the accommodating spaces of the two limiting components. A middle of one end surface of the stopping element protrudes outward to form a pivoting portion. The guiding element is mounted around an outside of the pivoting portion. The pivoting element is pivotally disposed in the stopping element.

In some examples, a substrate handling system includes a sheet processing machine and at least one alignment device that includes at least four stops. At least one stop is configured as a front stop, at least one stop is configured as a rear stop, and at least two stops are configured as lateral stops. The at least two lateral stops are arranged opposite one another, and the at least one front stop and the at least one rear stop are arranged opposite one another. The alignment device includes at least one support element that is configured as a propping element for propping at least one partial stack of sheets in the alignment device. Further, at least one respective support element is arranged at the at least two lateral stops and at the at least one rear stop.

A sheet feeding apparatus includes a sheet stacker, an air blower, a float regulator, and a controller. The sheet stacker stacks sheets. The air blower blows air to the sheets. The float regulator regulates a floating position of the sheets and is movable between a float regulating position at which the float regulator regulates floating of the sheets and a retracted position. The controller transmits position information of the float regulator to a notification device.

A medium feeding device includes: a medium mounting section onto which a medium to be fed is mounted; a feeding unit that feeds the medium mounted on the medium mounting section; and a supporting member that supports an end in a width direction of the medium mounted on the medium mounting section and that supports the medium at a higher position than the medium mounting section in a direction of loading of the medium, the width direction being a direction crossing a feed direction.

A sheet feeding device, which is included in an image forming apparatus and includes a device attachment body, includes a sheet container configured to accommodate a sheet, a support configured to support a lower face of the sheet in the sheet container, a sheet width regulator configured to regulate a position of the sheet in a sheet width direction, a conveying force applier configured to apply a sheet conveying force in a sheet conveying direction to the sheet in the sheet container, and a sheet guide disposed above the sheet in the sheet container and configured to regulate movement of the sheet in an upper direction.

A sheet conveying apparatus includes a discharge tray having a support surface supporting a sheet discharged by a discharge unit of a conveyor. A first stopper is provided on the support surface. A movable member is provided on the support surface between the discharge unit and the first stopper. The first stopper is changeable between a first position at which the first stopper protrudes from the support surface and a second position at which the first stopper is stored in the discharge tray. The movable member is changeable between a third position at which the movable member protrudes from the support surface and a fourth position located nearer to the support surface than the third position. The first stopper is changed from the first position to the second position in conjunction with a change of the movable member from the third position to the fourth position.

Provided are a floating restricting member restricting the floating position of a bundle of sheets; and a holding mechanism holding the floating restricting member relative to a side fence. The floating restricting member includes a sheet contact section being brought into contact with the sheets from above; and a sheet-floating restricting section restricting the floating position of the floating sheet that is floated while air is blown thereto. The holding mechanism sets the floating restricting member in the initial state where the sheet-floating restricting section restricts the floating position of the sheet, in the sheet-placing time retracted state where the sheets are pushed against the sheet contact section so that the floating restricting member is retracted, and in the sheet-ejecting time retracted state where, when the sheets are to be removed, the sheet is pushed against the sheet contact section from below so that the floating restricting member is retracted.

A height regulating portion is integrally formed with a pressing member provided in a first side regulating plate configured to regulate a position of a sheet in a sheet feed cassette, and the pressing member is provided turnably in the first side regulating plate and movably to project and retract positions. Then, when the sheet abuts with the height regulating portion and the height regulating portion is pressed from above by the sheet when the sheet is stored, the pressing member is moved, while turning, to the retract position.

The present invention provides a sheet feeding apparatus capable of feeding sheets at a proper position without a regulating member being bent even if a cassette unit is closed in a state in which a large volume of sheets are stacked. A large-volume feeding deck includes a non-reference-side regulating plate, an external casing plate, and positioning members, which are movable relative to the cassette unit.

A sheet feed device includes a sheet storage portion, a first regulation portion, a feed portion, and a second regulation portion. The sheet storage portion is attached to an apparatus main body in a detachable manner. A sheet is stored in the sheet storage portion. The first regulation portion stands on a bottom surface of the sheet storage portion and regulates a position of the sheet in a predetermined width direction by externally abutting on a first side of the sheet in the width direction. The feed portion is provided in the apparatus main body and feeds the sheet in a feed direction perpendicular to the width direction. The second regulation portion is provided in the apparatus main body and regulates a position of the sheet by externally abutting on the first side at a downstream of the first regulation portion in the feed direction.
