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 sheet feeding apparatus includes a first sheet storage portion and a second sheet storage portion disposed side by side with the first sheet storage portion. The sheet feeding device includes a sheet bundle moving member configured to transfer sheets in the second sheet storage portion to the first sheet storage portion and a pickup roller configured to feed the sheet by abutting against the sheet stored in the first sheet storage portion. When transferring the sheet bundle in the second sheet storage portion to the first sheet storage portion, the pickup roller is rotated in the same direction as that during feeding.

A conveying apparatus includes: a first casing having a first bottom portion and formed with a conveyance path in which a sheet is conveyed; a first tray provided for the first casing and supported by the first bottom portion; a first feeding section arranged above the first tray in the first casing and configured to feed a sheet supported by the first tray in a feeding direction toward the conveyance path; a second casing being detachably attached to the first casing and located below the first bottom portion in a state that the second casing is attached to the first cashing; a second tray provided for the second casing; and a second feeding section arranged above the second tray in the second casing and configured to feed a sheet supported by the second tray in the feeding direction toward the conveyance path.

A sheet-supply tray device for use with an image recording apparatus, includes a lower sheet-supply tray and an upper sheet-supply tray. The upper sheet-supply tray includes a main body, a leading-end stopper, a trailing-end stopper and a side-end stopper. The main body includes a support surface that supports a recording sheet. The leading-end stopper is fixed on the main body and stops a leading end of the recording sheet. The trailing-end stopper includes a trailing-end contact surface having a trailing-end protrusion extending over an upper surface of a trailing-end portion of the recording sheet toward the leading-end stopper. The trailing-end contact surface contacts a trailing end of the recording sheet. The side-end stopper includes a side-end contact surface that contacts a side end of the recording sheet. The side-end contact surface has at least one side-end protrusion extending over an upper surface of a side-end portion of the recording sheet.

A sheet paper conveyor includes pairs of conveyor guides that form a sheet paper conveyance path between guide surfaces which face each other with a predetermined conveyance path width between them and which are parallel to each other, and that are engaged with end portions of pairs of connection-side conveyor guides that form a conveyance path for the sheet paper using connection subject conveyance path guide surfaces that face each other with the conveyance path width between them and are parallel to each other, and with one end portions in a conveyance direction of the sheet paper. Supporting portions rotatably support the pairs of conveyor guides in accordance with positions of the pairs of connection-side conveyor guides such that the conveyance path width is maintained and such that the parallel state between the guide surfaces is maintained.

A medium processing apparatus includes a receiving and dispensing port, a discriminating unit, a temporary storage, a reject cassette in which an abnormal medium temporarily stored in the temporary storage and a carried abnormal medium among media being withdrawn are collected and stored, a plurality of recycling cassettes configured to store media to be withdrawn, a first driving unit configured to drive a carrying path between an outlet of the discriminating unit and each of the receiving and dispensing port and the temporary storage, a second driving unit configured to drive a carrying path between an inlet of the discriminating unit and an inlet of the reject cassette and be a belt-roller type, and a third driving unit configured to drive a carrying path between the inlet of the reject cassette and each of inlets of the plurality of recycling cassettes and be a belt-guide type.
