Abstract

A sheet feeding apparatus includes a switchable transmission mechanism disposed between a pickup roller and a driving source, and switches the driving source between a first state for rotating in the forward direction to rotate the pickup roller, and a second state for not rotating the pickup roller, the forward direction is opposite to a direction in which the driving source is rotated to rotate a feeder roller in a sheet feed direction. The sheet feeding apparatus also includes a control portion rotating the driving source in the forward direction to rotate the pickup roller in a sheet supply direction, and switches the switchable transmission mechanism between the first state, when a sheet is supplied from a sheet holding portion, and the second state, when the sheet is fed by the feeder roller.
