An image reading apparatus includes: a document transport route along which a document inserted into the image reading apparatus from a front side is transported backward; a reader that reads an image of the document; an ejection guide that upwardly guides the document being fed after the document is ejected backward from the document transport route; and a transport-force-applying mechanism that applies a transport force to the document. The transport force applied by the transport-force-applying mechanism to a first side of the document is greater than the transport force applied by the transport-force-applying mechanism to a second side of the document, the first side being positioned on a first-directional side in a width direction intersecting a document transport direction, the second side being positioned a second-directional side that is opposite to the first-directional side. The ejection guide is positioned asymmetrically toward the first-directional side in the width direction.

A sheet separating device includes a stacker, a pickup member, an air supplier and a sheet floating restraint. The stacker is configured to stack a plurality of sheets. The pickup member is configured to convey the plurality of sheets one by one from the stacker. Tile air supplier includes ail air outlet, at a downstream side of the stacker in a sheet conveyance direction. The air supplier is configured to blow air toward a downstream end of the plurality* of sheets in the sheet conveyance direction. The sheet floating restraint is configured to restrict floating of a part of the plurality of sheets separated by air blown from the air outlet. The sheet floating restraint is replaceable with another sheet floating restraint. The sheet floating restraint and said another sheet floating restraint have respective shapes different from each other.

A sheet conveying device includes a sheet placement table, a sheet discharge table, a conveyance mechanism, raising/lowering mechanism, and a raising/lowering control portion. The sheet discharge table is located below the sheet placement table. The conveyance mechanism conveys a sheet placed on the sheet placement table onto the sheet discharge table via an execution position at which image processing is executed by an image processing portion. The raising/lowering mechanism raises and lowers the sheet placement table. The raising/lowering control portion controls the raising/lowering mechanism to lower the sheet placement table when a human detection sensor configured to detect a human in a detection region has detected a human in the detection region.

The raising/lowering mechanism raises and lowers the sheet placement table. The raising/lowering control portion controls the raising/lowering mechanism to raise and lower the sheet placement table to a target position that is determined in accordance with a size of the sheet on the sheet discharge table.

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.

An image reading apparatus includes a first roller pair forming a first nip portion, a second roller pair forming second nip portions, an image information reading unit, and a sheet detecting unit. The second roller pair includes a recessed portion formed between the second nip portions of the second roller pair with respect to a rotational axis direction. The sheet detecting unit is provided so that at least a part thereof enters the recessed portion. The first roller pair forms the first nip portion so as to nip a sheet in a region overlapping with the recessed portion with respect to the rotational axis direction and to deliver the sheet, nipped in the first nip portion, to the second nip portions.

A control portion controls a reading portion and a discharge portion, and when a document is placed in a document placement portion, a transport path transports the document, and the reading portion reads an image of the document. When the discharge portion discharges the document for which reading is completed by the reading portion, a document receiving portion receives the document discharged by the discharge portion. The document receiving portion has a first region that overlaps the document placement portion when seen in a vertical direction, and a second region that does not overlap the document placement portion when seen in the vertical direction, and the discharge portion discharges the document so that at least part of the document is placed on the second region.

A medium-transporting device includes: a medium-support section that has a first mounting surface inclined relative to a horizontal plane; a transport path for transporting a medium; a discharge stacker that is configured to switch between an extended state in which a second mounting surface that is inclined relative to the horizontal plane and that receives the medium discharged along the transport path is formed and a stored state in which the second mounting surface is stored in the medium-transporting device, a control section is configured to perform first control of switching the discharge stacker from the extended state to the stored state after the medium is discharged to the second mounting surface and second control of not switching the discharge stacker from the extended state to the stored state such that the medium remains mounted on the second mounting surface.

An image scanning apparatus includes an image sensor to scan a manuscript, a transfer apparatus to pick up the manuscript and move the manuscript to a manuscript transfer path, and a loading apparatus to load the manuscript scanned by the image sensor. The loading apparatus includes a discharge tray to hold a discharged manuscript and a guide member to have one end rotatably disposed on the manuscript above an upper part of the discharge tray at an angle formed relative to the discharge tray based on a type of the manuscript.

A sheet discharge device includes a sheet discharge tray, a stopper, a sheet size detection unit, and a display unit. In the sheet discharge tray, sheets discharged from a sheet discharge port are stacked on the upper surface. The stopper is provided on a upper surface side of the sheet discharge tray and is movable to a position corresponding to the leading end of each of a plurality of sheet sizes to be used in a sheet discharge direction, and regulates the position of the leading end of the sheet. The sheet size detection unit detects the sheet size corresponding to the position of the stopper. The display unit visually displays the sheet size detected by the sheet size detection unit.
