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 feed tray with a first guide, a main body with a second guide, a guide member disposed at the sheet feed tray, and a contact portion located at the main body. The sheet feed tray is movable in a first direction. The guide member is movable between a protruding position and a withdrawn position. The guide member at the protruding position is disposed downstream of the first guide in a sheet conveyance direction and upstream of the second guide in the first direction such that the guide member overlaps the second guide in the first direction. The guide member at the withdrawn position does not overlap the second guide in the first direction. The contact portion is configured to, as the sheet feed tray moves from the main body, contact and move the guide member from the protruding position toward the withdrawn position.

A discharge tray includes a main tray having a support face that supports discharged paper, and an extension tray being supported by the main tray, and being capable of movement between a storage position in which the extension tray is stored in the main tray and an extended position in which the extension tray has been moved to extend along a discharge direction of the paper from a leading end side of the main tray in the discharge direction. A pair of first projections is provided to both ends at the discharge direction leading end side of the main tray, and a pair of second projections that project upward is provided to both ends at the discharge direction leading end side of the extension tray. The pair of second projections are positioned to the inside of the pair of first projections in a width direction orthogonal to the discharge direction.

In accordance with an embodiment, a paper feed apparatus comprises a paper feed section, a separation section, an abutting section and a friction force variable section. The paper feed section feeds an image receiving medium. The separation section is arranged at the downstream side of the paper feed section in a conveyance direction of the image receiving medium. In a case in which a plurality of the image receiving media fed from the paper feed section is overlapped, the separation section separates the plurality of the image receiving media that is overlapped. The abutting section abuts against the image receiving medium fed from the paper feed section. The friction force variable section changes a friction force of the abutting section against the image receiving medium.

According to one embodiment, a sheet separator has a first driving roller and a pressing body. The first driving roller rotates about a first rotation shaft. The first driving roller conveys a sheet bundle including a plurality of sheets. The pressing body is capable of approaching the first driving roller. The first driving roller is rotatable in a first direction with the sheet bundle sandwiched between the first driving roller and the pressing body. The pressing body pivots in the first direction about the first rotation shaft with the sheet bundle sandwiched between the first driving roller and the pressing body to cause the plurality of sheets to deviate from one another at edges.

The medium conveying device, comprises (1) a feeder configured to feed a print medium in a conveyance direction; (2) a stacker configured to stack the print medium fed by the feeder; (3) a first guide arranged in downstream side of the print medium in the conveyance direction, the first guide including a first guide surface configured to guide a downstream edge of the print medium stacked on the stacker; and (4) a second guide arranged to be movable with respect to the first guide, the second guide including a second guide surface configured to guide the downstream edge of the print medium stacked on the stacker, wherein the second guide configured to move with respect to the first guide such that the second guide surface protrudes with respect to the first guide surface in an upstream direction as the stacked amount of the print medium stacked on the stacker decreases.

A sheet conveying device includes a discharging roller pair, a discharge sheet holding portion, and a stopper member. The discharging roller pair discharges the sheet member outside from a sheet discharge port by rotating in a forward rotational direction. The discharging roller pair includes a first conveying roller, and a roller member. The discharge sheet holding portion is for holding the sheet member discharged outside by the discharging roller pair. The stopper member is swingably supported on a rotational shaft of the first conveying roller. The stopper member allows the sheet member to be discharged to the discharge sheet holding portion when the discharging roller pair rotates in the forward rotational direction, and prevents the sheet member from intruding into the nip portion from the discharge sheet holding portion when the discharging roller pair rotates in the reverse rotational direction.

An image forming apparatus including: a sheet feeding tray configured to support a sheet; and an apparatus main body configured to support the sheet feeding tray so as to be moveable in a direction parallel with a sheet feeding direction, the apparatus main body including a chute configured to guide the sheet that is fed from the sheet feeding tray, wherein the sheet feeding tray includes a guiding member configured to be displaced between an engaging position at which the guiding member engages with the chute and restrains movement of the sheet feeding tray and a separation position at which the guiding member separates from the chute and permits movement of the sheet feeding tray, and wherein the guiding member is configured to guide the sheet that is fed from the sheet feeding tray toward the chute when the guiding member is located at the engaging position.

An image reading apparatus, having a housing, a feed tray, and a reader sensor, is provided. The housing includes a reversing guide, a discharge tray, and an opening. The reversing guide is configured to reverse a first face and a second face of a sheet and guide the sheet from a first position toward a second position in a direction from a rear side toward a front side at the first position and in a direction from the front side toward, the rear side at the second position. The discharge tray is arranged at a position lower than the reversing guide and is configured to support the sheet discharged from the conveyer path. The opening is formed between the reversing guide and the discharge tray and is configured to expose the sheet supported by the discharge tray so that the sheet is removed through the front side of the housing.

A sheet feeder comprises a sheet stacking unit which stacks sheets, a sheet pickup unit which picks up a sheet from one side of the stacked sheets on the sheet stacking unit, a sheet separating and feeding unit which separately feeds sheets one by one to a conveyance path, an orientation holding unit which holds a feed orientation of a sheet, and a biasing unit which biases the orientation holding unit from a retracted position to a projecting position. A projection amount of the orientation holding unit from an inclined surface increases as the number of stacked sheets decreases, and the projection amount from the inclined surface decreases as the number of stacked sheets increases.
