Abstract
A sheet feeding apparatus includes a middle plate, a lifter mechanism, and a sheet-feed roller. The sheet-feed roller can move to a first position retracted from the sheet, a second position lower than the first position for feeding the sheet, and a third position lower than the second position. The sheet feeding apparatus has a position control mode in which when a sheet is fed, the sheet-feed roller is moved from the first position to the third position and stopped there, the middle plate is moved toward the sheet-feed roller by the lifter mechanism, the sheet stacked on the middle plate is brought into abutment against the sheet-feed roller, the middle plate is moved until a position detection sensor outputs the detection signal that the sheet-feed roller is in the second position, and a height of the sheet is controlled.
