摘要： When a retard roller is rotating in a sheet feeding direction, the rotation is transmitted to a pickup roller and the pickup roller rotates in a direction for conveying the sheet. When the retard roller is rotating in a direction opposite to the sheet feeding direction or is stationary, the pickup roller does not feed the sheet. Therefore, in a successive feeding operation, the sheet to be fed next is always conveyed such that the leading end thereof reaches a nip position between a feed roller and the retard roller. Therefore, the intervals between the sheets are uniform in the successive feeding operation.

摘要： 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.
