Patent ID: 8172225

Claim:
A feeding device comprising: a conveying roller configured to selectively rotate in a forward direction and a reverse direction, the conveying roller configured selectively to convey a sheet toward a downstream side in a conveying direction when the conveying roller is rotated in the forward direction, and to convey the sheet in a reverse conveying direction opposite the conveying direction when the conveying roller is rotated in the reverse direction; a particular guide member positioned on an upstream side of the conveying roller in the conveying direction and configured to guide the conveyed sheet toward the conveying roller, the particular guide member comprising a stopper configured to contact an end portion of the sheet when the sheet is conveyed in the reverse conveying direction by the reverse rotation of the conveying roller, thereby stopping movement of the sheet in the reverse conveying direction when the end portion of the sheet contacts the stopper; and a control unit configured to control the conveying roller to execute: a first forwarding rotation in which the conveying roller is rotated in the forward direction, such that the sheet is conveyed in the conveying direction to a predetermined position; a first reversing rotation in which the conveying roller is rotated in the reverse direction after the sheet has been conveyed to the predetermined position by the first forwarding rotation, such that the sheet is conveyed a predetermined amount in the reverse conveying direction, wherein the end portion of the sheet contacts the stopper while executing the first reversing rotation; and a second forwarding rotation in which after the first reversing rotation, the conveying roller is rotated in the forward direction again, such that the sheet is conveyed toward the conveying roller, wherein the control unit is configured to control the conveying roller, such that the sheet is nipped by the conveying roller without being released from the conveying roller from an end of the first forwarding rotation to a beginning of the second forwarding rotation.
