Stacking device and image forming apparatus

摘要

A stacking device includes: a first stacking portion having a stacking surface on which a sheet is stacked; a widthwise direction regulating unit, provided movably relative to the first stacking portion in a widthwise direction of the sheet, for regulating a widthwise position of the sheet stacked on the stacking surface; a second stacking portion provided rotatably relative to the first stacking portion between a first position and a second position. The second stacking portion is overlaid on the first stacking portion at the first position and supports, at the second position, an upstream portion of the sheet with respect to a feeding direction of the sheet fed by a sheet feeding unit. The second stacking portion is provided with a cut-away portion to avoid interference with the widthwise direction regulating unit when rotates between the first position and the second position.

主权项

1. A stacking device for stacking a sheet fed by a sheet feeding unit, comprising:
a first stacking portion having a stacking surface on which the sheet is stacked; a widthwise direction regulating unit, provided movable relative to said first stacking portion in a widthwise direction of the sheet, for regulating a widthwise position of the sheet stacked on the stacking surface; a second stacking portion provided rotatable relative to said first stacking portion between a first position and a second position, wherein said second stacking portion is overlaid on said first stacking portion at the first position and supports, at the second position, an upstream portion of the sheet with respect to a feeding direction of the sheet fed by the sheet feeding unit, wherein said second stacking portion includes a first end portion and a second end portion, in one side with respect to the widthwise direction, for constituting an end surface of said second stacking portion and for supporting the sheet and includes a recessed portion between said first end portion and said second end portion with respect to the feeding direction, and wherein said recessed portion is recessed inwardly from said first end portion and said second end portion with respect to the widthwise direction and is in non-contact with said widthwise direction regulating unit when said second stacking portion rotates between the first position and the second position.
