Abstract:
1. A sheet feeding apparatus comprising: a sheet container for containing a plurality of stacked sheets; an elevation/lowering driving unit for elevating and lowering the sheet container; a sheet conveying unit for sequentially taking out the sheets from an uppermost layer put in contact with the sheet conveying unit by elevating the sheet container by the elevation/lowering driving unit and conveying the sheets to a predetermined conveyance path; a regulating unit provided so as to be slidable on the sheet container for regulating a set position of a sheet; a position detector for detecting a position of the regulating unit; and a contact detector for detecting a contact state between the uppermost layer of the sheets contained in the sheet container and the sheet conveying unit, wherein the elevation/lowering driving unit lowers the sheet container when a change in the position of the regulating unit is detected by the position detector in a state in which the uppermost layer of the sheets contacts the sheet conveying unit; and further comprising: a receiving unit for receiving information input externally for setting a lowered amount of the sheet container; and a storage for storing the received information, wherein the elevation/lowering driving unit lowers the sheet container by the lowered amount stored in the storage when the position detector detects a change in the position of the regulating unit.
