Abstract:
A sheet feeding apparatus includes a stacking surface on which a sheet is stacked, a feed portion configured to feed the sheet in a sheet feeding direction, first and second detecting portions disposed at positions different from each other in a width direction orthogonal to the sheet feeding direction and so as to overlap with the stacking surface in a view from a height direction orthogonal to the stacking surface, the first and second detecting portions being configured to detect height positions which are positions in the height direction of an uppermost sheet, and a control portion configured to stop feeding the sheet by the feed portion based on at least one detection result of the first and second detecting portions in feeding the sheet.

Claim (Index 21):
An image forming apparatus, comprising:\n a sheet feeding apparatus comprising:\n a stacking surface on which a sheet is stacked; \n a feed portion configured to feed the sheet stacked on the stacking surface in a sheet feeding direction; \n a first detecting portion comprising a first light emitting portion configured to irradiate an uppermost sheet stacked on the stacking surface with light and a first photo-sensing portion configured to receive the light irradiated from the first light emitting portion and reflected by the uppermost sheet, disposed so as to overlap with the stacking surface in a view of a height direction orthogonal to the stacking surface, and configured to detect a height position which is a position of the uppermost sheet in the height direction based on a time from when the first light emitting portion irradiates the light and until when the light irradiated from the first light emitting portion is received by the first photo-sensing portion; \n a second detecting portion comprising a second light emitting portion configured to irradiate the uppermost sheet stacked on the stacking surface with light and a second photo-sensing portion configured to receive the light irradiated from the second light emitting portion and reflected by the uppermost sheet, disposed at a position different from that of the first detecting portion in a width direction orthogonal to the sheet feeding direction and so as to overlap with stacking surface in view of the height direction, and configured to detect a height position of the uppermost sheet at a position different from a detecting position of the first detecting portion in the width direction based on a time from when the second light emitting portion irradiates the light and until when the light irradiated from the second light emitting portion is received by the second photo-sensing portion; and \n a control portion configured to start feeding the sheet stacked on the stacking surface by the feed portion and to stop feeding the sheet by the feed portion, the control portion being configured to stop feeding the sheet based on at least one detection result of the first and second detecting portions in feeding the sheet; \n an image reading portion configured to read an image of the sheet fed by the sheet feeding apparatus; and an image forming unit configured to form the image based on information of the image read by the image reading portion.
