The third tray includes a third support surface and a fourth support surface. The third support surface includes a protrusion which protrudes upward to be positioned above the first support surface in a state that the third tray is in the first pivoting position. The third tray overlaps with the first support surface in a state that the second tray is in the first position and that at least a part, of the third tray, except for the protrusion is positioned below the first support surface, and the third tray does not overlap with the first support surface in a state that the second tray is in the second position.

An image reading device includes a tray unit, a recording unit disposed above the tray unit, an outer guide defining a curved path extending from the tray unit to the recording unit, a sheet feeder configured to feed a sheet from the tray unit to the curved path, and a return guide disposed between the recording unit and the tray unit. The return guide pivots about a shaft and guides the sheet having an image recorded thereon back to the curved path. The tray unit includes at least one supporting portion. The return guide includes at least one supported portion. The at least one supporting portion of the tray unit engages the at least one supported portion of the return guide such that the return guide takes a guiding position in which the return guide defines a return path extending to the curved path.

There is provided a conveyance apparatus including: a main body including a drive source, and a conveyance portion to which a drive force is transmitted from the drive source; an equipped unit including a drive portion to which the drive force is transmitted from the drive source in the main body; a first gear provided in the main body and rotated by the drive force transmitted thereto from the drive force; a first gear holder provided swingably in the main body to support the first gear; a second gear provided in the equipped unit to transmit the drive force to the drive portion; a second gear holder provided swingably in the equipped unit to support the second gear; and a third gear supported by a connecting shaft connecting the first and second gear holders to engage respectively with the first and second gears.

A sheet conveying device includes a conveyor, a first cover, a second cover movable in conjunction with the first cover, and a restricting portion movable between a restricting position at which the second cover is restricted from being moved from a first position toward a second position and an allowable position at which the second cover is allowed to be moved from the first position toward the second position. The restricting portion is located at the restricting position when the first cover is located at the closed position, and the restricting portion is moved from the restricting position to the allowable position in conjunction with the first cover when the first cover is moved from the closed position toward the opened position.

A document conveying apparatus is provided with a document tray and a discharge tray disposed below the document tray. The document tray includes an upper tray member, a lower tray member, a movable tray member, and a driving portion configured to move the upper tray member and the movable tray member integrally to a raised position and a lowered position. The movable tray member is configured to be moved in a width direction between a first position and a second position in which the movable tray member is retracted into below the upper tray member. The document tray includes a shutter configured to cover a gap created between the upper tray member and the lower tray member. The gap is created by the upper tray member and the movable tray member being moved to the raised position and the movable tray member being moved to the second position.

An image reading device includes a tray unit, a recording unit disposed above the tray unit, an outer guide defining a curved path extending from the tray unit to the recording unit, a sheet feeder configured to feed a sheet from the tray unit to the curved path, and a return guide disposed between the recording unit and the tray unit. The return guide pivots about a shaft and guides the sheet having an image recorded thereon back to the curved path. The tray unit includes at least one supporting portion. The return guide includes at least one supported portion. The at least one supporting portion of the tray unit engages the at least one supported portion of the return guide such that the return guide takes a guiding position in which the return guide defines a return path extending to the curved path.

A sheet conveyance apparatus includes: a supply-sheet supporter having a supply support surface that supports a sheet; a conveyor configured to convey the sheet from the supply-sheet supporter along a conveyance path; and a discharged-sheet supporter disposed above the supply-sheet supporter and configured to support the sheet conveyed by the conveyor. The discharged-sheet supporter includes: a particular end portion located farthest from the conveyor in the discharged-sheet supporter and opposed to the supply support surface from above; and a movable member including the particular end portion at one of opposite end portions of the movable member, which one is farther from the conveyor than another of the opposite end portions. The movable member is pivotable in a direction in which a distance between the particular end portion and the supply support surface is increased.

There is provided a sheet tray including: first, second and third trays. The second tray moves between a first position and a second position in which an overlapping area is smaller than that obtained in the first position. The third tray includes a third support surface and a fourth support surface. The third support surface includes a protrusion which protrudes upward to be positioned above the first support surface in a state that the third tray is in the first pivoting position. The third tray overlaps with the first support surface in a state that the second tray is in the first position and that at least a part, of the third tray, except for the protrusion is positioned below the first support surface, and the third tray does not overlap with the first support surface in a state that the second tray is in the second position.

A first feeder contacts a first surface of a first sheet held in a first tray and feeds the first sheet toward a recording unit. A second feeder contacts a first surface of a second sheet held in a second tray and feeds the second sheet toward the recording unit. An inner member is disposed above a standing plate. An outer member comprises an upstream portion opposing the standing plate, and a downstream portion opposing the inner member. The inner member guides the first surface of the first sheet and the first surface of the second sheet. The standing plate guides the first surface of the second sheet. The upstream portion of the outer member guides a second surface of the second sheet, and the downstream portion guides a second surface of the first sheet and the second surface of the second sheet. The standing plate moves relative to the outer member.

A conveyor includes: a conveyor roller unit including a conveyor roller; a transmission mechanism; a driven roller unit including a driven roller; a supporting member which supports the conveyor roller unit and the driven roller unit to allow the conveyor roller unit and the driven roller unit to take a conveyance position or a retracted position; and a movable member which is movable between a first position where the conveyor roller and the driven roller take the conveyance position and a second position where the conveyor roller and the driven roller take the refracted position. The movable member moves from the second position to the first position when the conveyor roller in the second position rotates in one direction.
