Abstract
A sheet feeder includes a feed roller feeding a sheet while rotating in a feeding direction, a driving gear that rotates in a predetermined direction and transmits a driving force, a first gear mechanism transmitting the force to the feed roller to rotate the feed roller in a reverse direction opposite to the feeding direction, and a second gear mechanism transmitting the force to the feed roller to rotate the feed roller in the feeding direction. The driving gear includes a first engaging member that engages with the first gear mechanism and transmits the force to the first gear mechanism at a rotational angle of the driving gear within a first range, and a second engaging member that engages with the second gear mechanism and transmits the force to the second gear mechanism at the rotational angle within a second range having no common range with the first range.
