A multi-function apparatus employs an in-body sheet discharge type configuration. The image forming device includes a front door and a multi-purpose tray. The front door is movable between a closed position set along a side surface at one side of a case of the image forming device and an opened position opened at the one side with respect to the side surface. The front door has an opening formed therein. The multi-purpose tray is provided to be selectively located at a non-use state at which the multi-purpose tray closes the opening and an in-use position at which the multi-purpose tray opens the opening. When the front door is located at the closed position and the multi-purpose tray is located at the non-use position, an upper end surface of the multi-purpose tray is exposed upward.

A sheet conveying apparatus, including: a sheet container; a roller; an arm rotatably supporting the roller; and a presser plate for pressing sheets in the container, wherein distal and basal portions of the presser plate define a bend angle when bent, the bend angle being an angle defined on one side of the presser plate farther from the arm, the bend angle being maintained at an obtuse angel in a first-amount loaded state of the container, and wherein a contact angle of the arm and the sheets at a contact position thereof is smaller than a maximum angle from a maximally loaded state to the first-amount loaded state, the maximum angle being an angle defined by: the basal portion in the maximally loaded state; and the arm whose roller contacts the presser plate in the maximally loaded state when assumed that the sheets are not loaded on the presser plate.

A medium discharge device includes a discharge roller pair that is provided with a discharge driving roller and a discharge driven roller which drivably rotates in contact with the discharge driving roller, and a medium receiving tray which receives the medium that is fed and discharged by the discharge roller pair, in which the medium receiving tray includes a guide member which guides such that a tip end of the medium which is discharged from the discharge roller pair enters the medium mounting surface at a predetermined angle, and the guide member is provided to be elastically displaceable in an advancing and retreating direction with respect to the medium mounting surface of the medium receiving tray and is displaced in a direction coming close to the medium mounting surface according to raising of a pressing load due to the medium that is discharged to the medium receiving tray.

An automatic document feeding device includes a document tray, an ejection tray, and a document takeout port. The document tray is rotatably attached to a rotation fulcrum provided in a body of the automatic document feeder, to load a document. The document tray includes a first positioner and a second positioner. The first positioner is disposed at a front side of the body in a direction perpendicular to a document feed direction. The second positioner is disposed at a depth side of the body in the direction perpendicular to the document feed direction. The first positioner is disposed upstream from the rotation fulcrum in the document feed direction and above the document takeout port in the body. An upper portion and side surfaces of the first positioner in the direction perpendicular to the document feed direction are surrounded by the document tray in a closed state of the document tray.

A sheet feeding device, which is included in an image forming apparatus, includes a reference face, a sheet loader, an air blowing device, an air drawing device, and a conveying body. The reference face stands upwardly at a downstream side of a sheet conveying direction. The sheet loader includes a body and a leading end disposed downstream from the body in the sheet conveying direction. The sheet loader moves upwardly to a position where the leading end rotates downwardly to the body. The air blowing device blows air toward a sheet bundle loaded on the sheet loader and lift an uppermost sheet of the sheet bundle. The air drawing device is configured to draw the uppermost sheet. The conveying body conveys the uppermost sheet in the sheet conveying direction while the uppermost sheet is in contact with the air drawing device due to attraction by air.

An image forming apparatus includes an apparatus body, an image forming portion, a sheet feeding port, a bypass tray, a rotation support, and a temporary retainer. The image forming portion is disposed in the apparatus body to form an image on a recording medium. The sheet feeding port is disposed upstream from the image forming portion of the apparatus body in a sheet feeding direction. The bypass tray is disposed to be storable in the apparatus body. The bypass tray loads the recording medium to be fed toward the sheet feeding port. The rotation support supports the bypass tray. The temporary retainer positions the bypass tray both in a vertical direction relative to the sheet feeding port and in a perpendicular direction perpendicular to the sheet feeding direction. The temporary retainer temporarily retains the bypass tray.

A medium discharge device includes a discharge roller pair that is provided with a discharge driving roller and a discharge driven roller which drivably rotates in contact with the discharge driving roller, and a medium receiving tray which receives the medium that is fed and discharged by the discharge roller pair, in which the medium receiving tray includes a guide member which guides such that a tip end of the medium which is discharged from the discharge roller pair enters the medium mounting surface at a predetermined angle, and the guide member is provided to be elastically displaceable in an advancing and retreating direction with respect to the medium mounting surface of the medium receiving tray and is displaced in a direction coming close to the medium mounting surface according to raising of a pressing load due to the medium that is discharged to the medium receiving tray.

A sheet feeding device includes a document mounting board, in which a downstream end of the document mounting board in the feeding direction of the documents in the feed mechanism is connected to a scanner body so as to be rotatable about a first turning shaft parallel to a rotation shaft of a pickup roller, the first turning shaft is located downstream from the feed mechanism in the feeding direction of the documents in the feed mechanism, a mounting surface of the document mounting board on which the documents are mounted is located above the pickup roller when the documents are mounted on the document mounting board, and the document mounting board turns about the first turning shaft such that the mounting surface moves downward and the mounting surface moves downward from a contact portion of the pickup roller with the document when the documents mounted on the document mounting board are fed.

In a sheet feeding device, a document mounting board includes a first member that includes a first mounting surface and is located on the feed mechanism side in the feeding direction of the documents in the feed mechanism, the first mounting surface being inclined to a lower side toward the feed mechanism, and a second member that includes a second mounting surface on which the documents are mounted and is disposed on a side opposite to the side of the first member on which the feed mechanism is located, and the second member is connected to the first member to be rotatable about a second turning shaft and turns about the second turning shaft depending on the weight of the documents detected by the weight sensor to change an angle with respect to the first member.
