Patent ID: 8091890

Claim:
A medium feeding device comprising: a feed roller pair that includes a feed driving roller driven by power of a feeding motor and a feed driven roller to be rotationally driven, and feeds a medium to be fed toward the downstream side in a feed direction, the feed driving roller and the feed driven roller being separated from each other; a transport roller pair that transports the medium, which is fed by the feed roller pair, toward the downstream side in the feed direction, the transport roller pair including a transport driving roller that is disposed on the downstream side of the feed roller pair in the feed direction and is driven by power of a feeding motor and a transport driven roller that is rotationally driven; a medium guiding path section that guides the fed medium up to the transport roller pair; and a controller that makes a front end of the medium, which is a downstream end in the feed direction, be nipped by the transport roller pair by rotationally driving the transport driving roller in a downstream direction at the time of skew correction; makes the front end of the medium follow a nip line of the transport roller pair by rotationally driving the transport driving roller in an upstream direction; makes the front end of the medium be nipped by the transport roller pair by rotationally driving the transport driving roller and the feed driving roller in the downstream direction; and makes the feed driven roller and the feed driving roller be separated from each other while the transport driving roller is stopped, and rotationally drives the feed driving roller in the upstream direction.
