摘要： A sheet feed device has a tray with holding surface for holding sheets, a feed unit for feeding sheets from the tray, and a separation plate. The separation plate has an inclined surface and two or more separation portions that separate a sheet from the sheets held in the tray. At least one of the separation portions projects a first distance from the inclined surface. The separation plate also has a projection positioned on the inclined surface that projects a second distance from the inclined surface. The second distance is greater than the first distance. A first of the separation portions is positioned upstream of the particular projection in the sheet feed direction, and a second of the separation portions positioned downstream of the particular projection in the sheet feed direction.

摘要： A sheet conveying device includes a tray having a bottom surface. The tray holds at least one sheet therein, and has a recess formed in the bottom surface. A rotating member moves between a first position and a second position. In the first position, the rotating member contacts a sheet held in the tray, and in the second position, the rotating member is separated from the tray. The rotating member selectively rotates to convey a sheet held in the tray in a when the rotating member is in the first position. An operative portion moves in and out of the recess in the bottom surface of the tray, and movement of the operative portion corresponds to a movement of the rotating member into the second position.

摘要： An image recording apparatus includes a sheet-supply tray device, a sheet-supply roller and an image recording device. The sheet-supply tray device includes a first tray which accommodates a plurality of first recording media on a first tray surface thereof such that the first recording media are stacked on each other and a second tray which is placed on the first tray and which accommodates a plurality of second recording media on a second tray surface thereof such that the second recording media are stacked on each other. The second tray includes a base portion which is supported on the first tray and which constitutes a downstream tray surface that is a downstream side portion of the second tray surface in the sheet-supply direction, and a pivotable portion whose state is changeable between a stacked state in which the pivotable portion is supported on the first tray and an opening state in which the pivotable portion is pivoted relative to the base portion so as to open a space above the first tray and which constitutes an upstream tray surface that is an upstream side portion of the second tray surface in the sheet-supply direction. The pivotable portion includes a nip portion which constitutes a part of the upstream tray surface and which the sheet-supply roller advances toward and retracts from. In a state in which the pivotable portion is in the stacked state, at least one of (a) the nip portion and (b) a portion of the pivotable portion adjacent to the nip portion is supported by the base portion.
