Patent ID: 7883285

Claim:
An image recording apparatus, comprising: a sheet-supply tray device which accommodates a plurality of recording media; a sheet-supply roller which supplies the recording media one by one in a sheet-supply direction; and an image recording device which records an image on each of the recording media, wherein 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 including: 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, wherein the pivotable portion includes a nip portion which constitutes a part of the upstream tray surface, wherein the sheet-supply roller is configured to move toward and away from the nip portion, wherein 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, wherein in the state in which the pivotable portion is in the stacked state, a substantially middle portion of the pivotable portion in a direction perpendicular to the sheet-supply direction engages a corresponding portion of the base portion such that at least the middle portion of the pivotable portion is prevented from moving away from the corresponding portion of the base portion in a direction parallel to the downstream tray surface, wherein the middle portion of the pivotable portion constitutes the nip portion and the corresponding portion of the base portion constitutes the support portion, wherein one of the nip portion and the support portion includes a recessed portion while an other of the nip portion and the support portion includes a projection, and wherein the recessed portion and the projection engage each other so that the nip portion is prevented from moving away from the support portion in the direction parallel to the downstream tray surface.
