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 processing apparatus includes a first holding unit configured to hold one or more sheets and movable in a sheet transport direction, a first drive unit configured to move the first holding unit in a first direction along the sheet transport direction, a biasing member that biases the first holding unit in a second direction opposite to the first direction, and an energy storage unit that stores energy discharged from the biasing member.

Examples include a vibratory device that includes a pivotably arranged pile bearing device that defines a bearing plane, and that separates an upper half-space from a lower half-space. The vibratory device includes a front stop that can limit a pile forming region, a lateral stop, and a pile aeration device that includes a gas discharge device that is arrangeable relative to the pile bearing device. The gas discharge device is arranged to be transferrable between a lowered position and an aeration position. In the aeration position, the gas discharge device is at least partly arranged in the upper half-space, and when in the lowered position, the gas discharge device is arranged completely in the lower half-space. The pile aeration device may serve as a rear blower device and, based on a first transport direction, the pile forming region is arranged between the gas discharge device and the front stop.

A medium conveying apparatus includes a tray, and a side guide in which a side guide surface opposing to an end face of a medium placed on the tray is formed, wherein the side guide includes a side guide main body that is supported by the tray, and a movable member that is supported by the side guide main body so as to be stored and expanded, a height of the movable member relative to the tray is equal to a first height that is higher than a height of the side guide main body relative to the tray when the movable member is expanded, and is equal to a second height that is lower than the first height when the movable member is stored, and a notch is formed on the movable member such that a depression is formed on the side guide surface when the movable member is expanded.

A cassette portion includes a side guide, an end guide, and a paper detection portion. The side guide is movable in X direction and controls a motion of a first end portion of paper. The end guide is provided to the side guide to be movable in Y direction, and restricts a motion of a second end portion of the paper. The paper detection portion detects the first restricting position in the X direction of the side guide and a second restricting position in the Y direction of the end guide in a restricted state of the paper. The end guide includes a detection target portion formed such that detection information to be detected by the paper detection portion varies in the Y direction. The paper detection portion detects the first restricting position and the second restricting position by obtaining detection information from the detection target portion.

A sheet storage apparatus includes a storage apparatus body, a sheet stacking portion, a rear end regulation member, and a rear end regulation attachment. The sheet stacking portion has an opening opened in an upward and downward direction, and is movable upward and downward with respect to a bottom portion of the storage apparatus body. The rear end regulation attachment is detachably attached to the rear end regulation member, which regulates an upstream end position in the sheet feed direction of the sheet stacked on the sheet stacking portion. The rear end regulation attachment includes a regulating portion that extends toward the bottom portion through the opening. The rear end regulation attachment regulates the upstream end of the sheet on a position downstream, in the sheet feed direction, of a regulating position of the rear end regulation member.

A removable media tray with a two-axis media restraint system having a user-actuated rear media restraint operatively coupled to a side media restraint via a camming member. The rear media restraint includes a latching assembly for slidably latching with one of the indents along a track, each indent corresponding to a supported media length. The camming member having a predefined camming profile surface is coupled to and movable with the rear media restraint. As the rear media restraint moves along the track, camming member moves with the rear media restraint in the same direction engaging first and second cam follower portions of the side media restraint causing the side media restraint to move to contact a side edge of a media stack with the position of the side media restraint depending on a position of the first and second cam follower portions on the camming profile surface.

A document conveying apparatus is provided with a document tray, a feeding member, and a discharge tray disposed below the document tray. The document tray includes an upper tray member, a lower tray member, a movable tray member movable in a width direction orthogonal to a feeding direction of a document, a tray cover disposed to cover an underside of the movable tray member, and a driving portion. The driving portion moves the upper tray member and the movable tray member integrally to a raised position and a lowered position. The movable tray member and the tray cover are configured to be moved integrally in the width direction between a first position in which the movable tray member supports the document together with the upper tray member and a second position in which the movable tray member is retracted from the first position into below the upper tray member.

A media restraint for a removable media tray and slidably operable without the use of a pinching force. The media restraint slidably positionable on a track in a removable media tray and is operable without pinching. A pair of latching cams are used to engage the media restraint to the track and have serrated portions pivotally mounted to a bottom of the media restraint. The media restraint is operable by a finger of the user applying a downward force to the media restraint allowing a rack and pinion to horizontally translate a rack portion of the pair of latching cams away from the track and pivot the serrated portions away from the track and allowing the media restraint to be moved along the track. Upon removal of the downward force, a biasing member translates the latching cams back to reengage with the track.

Provided is a sheet conveyance apparatus that includes a housing in which a sheet conveyance unit configured to convey a sheet is stored, an opening and closing unit configured to open and close by rotating with respect to the housing, a feeding unit configured to feed a sheet, a rotation unit configured to support the opening and closing unit to rotate with respect to the housing, and a regulating unit configured to regulate the opening and closing unit. The rotation unit includes a rotating shaft that is attached to one of the opening and closing unit and the housing, and serves as a rotation center of the opening and closing unit in rotating, a first groove portion that is formed in the other of the opening and closing unit and the housing, and a lock unit configured to switch between locked and released states.
