The sheet stack tray has a movable part making contact with the upper conveying guide at least when it swings, and the movable part is movable between a sheet receiving position where it forms a sheet stack surface and a retracted position where it has swung upward from the sheet receiving position.

A medium conveyance device includes a body, a table in which a placement surface is formed and that is supported by the body movably to be arranged in a first area or a second area, a guide that is supported by the table movably to be arranged in a third area or a fourth area and that regulates move of an original that is placed on the table such that a height of the guide is lower when the guide is arranged in the fourth area than when the guide is arranged in the third area, and a mechanism that moves the guide along with move of the table such that the guide is arranged in the third area when the table is arranged in the first area and the guide is arranged in the fourth area when the table is arranged in the second area.

Disclosed is a loading unit for use in loading a bundle of objects to be conveyed, the loading unit being installed on a lifting member of a feeding device. The loading unit includes a first movable base on which a downstream side in a conveying direction of a bundle of objects to be conveyed is loaded, the first movable base being rotatable; and a second movable base on which an upstream side in the conveying direction of the bundle of objects is loaded, the second movable base being rotatable and disposed on a more upstream side in the conveying direction than the first movable base.

A medium discharge device includes: a discharge unit that discharges a medium; a first medium receiving tray that receives the medium discharged by the discharge unit; and a second medium receiving tray that is provided above the first medium receiving tray in a vertical direction and receives the medium discharged by the discharge unit. The second medium receiving tray is capable of changing a position between an advance position for receiving a medium, which is discharged, by causing at least an upstream zone of the tray including an upstream side end portion in a medium discharge direction to advance to a passing route of the medium from the discharge unit toward the first medium receiving tray and a retraction position to which the upstream zone retracts from the passing route.

A sheet conveying device includes a sheet conveying passage, an upper conveying guide provided in the sheet conveying passage and facing the upper surface of a sheet, a lower conveying guide facing the lower surface of the sheet, a conveying member conveying the sheet along the sheet conveying passage, a sheet stack tray arranged above the upper conveying guide. The upper conveying guide is swingable up and down, with one end part of it in the sheet conveying direction or in the sheet width direction perpendicular to the sheet conveying direction serving as a pivot shaft. The sheet stack tray has a movable part making contact with the upper conveying guide at least when it swings, and the movable part is movable between a sheet receiving position where it forms a sheet stack surface and a retracted position where it has swung upward from the sheet receiving position.

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 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.

According to one embodiment, provided is an automatic document feeder including a conveying unit, a first tray, a storage unit, and a paper discharge guide. The conveying unit is configured to convey paper to the paper discharge tray. The first tray is a paper discharge tray on which paper discharged by the conveying unit is stacked. The storage unit is a groove-shaped hole provided below the first tray. The paper discharge guide is a member for guiding paper having a predetermined size discharged by the conveying unit to the storage unit.

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.

Examples relating to determining stack height in imaging devices are described herein. According to one example, an imaging device includes an input roller assembly to transport a print medium towards an image-forming assembly of the imaging device. The input roller assembly can include a pinch roller for drawing the print medium from a media stack. The imaging device further includes a pressure plate movably coupled to a body portion of the imaging device and biased towards the pinch roller. The pressure plate may hold the media stack between itself and the pinch roller and is movable by a first distance from a neutral position when the media stack is there between. The first distance is measured from a fixed point to a measurement region on the pressure plate and can indicate an instantaneous stack height of the media stack.
