A feeding roller feeds a medium placed at a medium placement portion by forward rotation power supplied from a driving unit. A displacement portion displaces the feeding roller to an abutting position by the forward rotation power supplied from the driving unit and displaces the feeding roller to a separation position by reverse rotation power supplied from the driving unit. A power transmission unit includes a one-way clutch that transmits the forward rotation power, that is supplied from the driving unit, to the feeding roller but does not transmit the reverse rotation power, that is supplied from the driving unit, to the feeding roller.
