Abstract
A medium feeding device includes a medium feeding mechanism switching between a first state in which the medium is fed from the feeding tray and a second state in which the medium is not fed from the feeding tray, a feeding roller rotationally driven in a forward rotation direction, and a separation roller that is rotationally driven in the reverse rotation direction when the feeding roller is rotationally driven in the forward rotation direction, wherein when the separation roller is rotationally driven in the forward rotation direction, the feeding roller is configured to be passively rotatable with respect to the separation roller, and wherein a rotation direction of the first motor when the cam member switches the medium feeding mechanism from the first state to the second state is the same as a rotation direction of the first motor when the separation roller rotates in the forward rotation direction.
