A printing apparatus includes a stacking portion on which a print medium printed by a printing unit configured to perform printing is stacked, a discharge unit configured to discharge the print medium printed by the printing unit to the stacking portion, a passage forming portion arranged facing the stacking portion and configured to form a discharge passage of the print medium together with the stacking portion, and an outlet port located at a downstream end of the stacking portion and a downstream end of the passage forming portion in a conveying direction of the print medium. The passage forming portion includes an opening/closing portion which is displaceable between a closed position for forming the discharge passage and an open position for opening access to the stacking portion.

A housing is formed with a first opening and a sheet conveyance path. A tray is inserted into the housing through the first opening in a first direction and pulled out in a second direction opposite from the first direction. The tray supports a sheet. The tray includes a bottom plate, a front plate, and a cover. The bottom plate supports a sheet. The front plate protrudes upward from an end portion of the bottom plate in the second direction. The cover is configured to move between a first position at which the cover closes a second opening and a second position at which the cover opens the second opening. The second opening is defined by an end of a top plate in the second direction and an upper end of the front plate, the top plate covering an upper side of a space that accommodates a sheet.

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.

An electric paper tray includes a base, a paper holding element pivotally mounted to at least one side of the base, a power unit arranged at the base, and a lifting module connected between the paper holding element and the power unit. The lifting module is movably mounted under the paper holding element. When the lifting module is driven by the power unit to move to a first position, with respect to the base, the lifting module drives the paper holding element to make the paper holding element rotate to a closed position, when the lifting module is driven by the power unit to move to a second position, with respect to the base, the lifting module drives the paper holding element to make the paper holding element rotate to an opened position.

A medium accommodation cassette includes a first medium accommodation portion that forms a portion of a medium accommodation region and a second medium accommodation portion that forms a portion of the medium accommodation region and is configured to be switchable between a first state and a second state in which the second medium accommodation portion is displaced from a position thereof in the first state in a cassette removing direction so as to stretch the medium accommodation region. A step portion on a side surface, which is formed between the first medium accommodation portion and the second medium accommodation portion, is positioned inside an insertion/removal mouth when the second medium accommodation portion assumes the second state in the state in which the medium accommodation cassette is installed in the insertion/removal mouth.

A recording apparatus includes a recording head, a loading unit, a feeding unit, a cover, a detection unit, and a determination unit. The feeding unit feeds a recording medium loaded on the loading unit to a recording position where the recording head performs the recording. The cover moves between an opening state and a closing state. The determination unit determines a size of the loaded recording medium based on a result of a width detection operation. The recording head records an image per a determination result. If the cover closing is detected before the recording is performed, the determination unit performs the width detection operation to determine the recording medium size loaded on the loading unit. If the cover opening is detected and the recording apparatus receives a recording instruction, the determination unit performs the width detection operation to determine the recording medium size loaded on the loading unit.

A sheet feeding apparatus includes: a conveying roller; a separating roller which forms a nip portion by pressing the conveying roller and separates a sheet conveyed by the conveying roller one by one in the nip portion; a moving portion configured to move a stacking portion from a first position at which a sheet stacked in the stacking portion and a feeding roller are separated from each other to a second position at which the sheet stacked in the stacking portion abuts on the feeding roller; and a cover member which is movable between a third position to cover a rotation shaft of the separating roller and a fourth position to expose the rotation shaft of the separating roller, in which the cover member placed in the fourth position moves to the third position along with movement of the stacking portion from the first position to the second position.

Provided is an image forming system capable of reliably preventing others from removing and taking printed matter even though printing is executed beforehand. The confidential notation reading unit reads a confidential notation. The user storage tray has a structure from which outputted printed matter cannot be removed unless the opening/closing door is opened. The locking mechanism locks the opening/closing door. The sorting mechanism sorts the printed matter outputted from the image forming apparatus and outputs the printed matter to either the open tray or the user storage tray. The sorting control unit outputs printed matter to which a confidential notation is not added to the open tray, and outputs a printed matter to which a confidential notation is added to the user storage tray, respectively.

A sheet feeding apparatus includes: a conveying roller; a separating roller which forms a nip portion by pressing the conveying roller and separates a sheet conveyed by the conveying roller one by one in the nip portion; a moving portion configured to move a stacking portion from a first position at which a sheet stacked in the stacking portion and a feeding roller are separated from each other to a second position at which the sheet stacked in the stacking portion abuts on the feeding roller; and a cover member which is movable between a third position to cover a rotation shaft of the separating roller and a fourth position to expose the rotation shaft of the separating roller, in which the cover member placed in the fourth position moves to the third position along with movement of the stacking portion from the first position to the second position.

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.
