Claim Text:
1. A feed device, comprising: a first roller; a second roller that is configured to: a first protruding portion provided on the second roller and that protrudes in a direction that is parallel to a rotational axis of the second roller; a plurality of second protruding portions provided in the first protruding portion and that protrude in directions that are orthogonal to the rotational axis of the second roller; a first restricting member that is configured to move between a first restricting position and a first permitting position, the first restricting position being a position in which the first restricting member is in a first rotation area and restricts rotation of the second roller in the forward rotation direction, the first rotation area being an area in which the first protruding portion moves when the first protruding portion rotates in the forward rotation direction, the first permitting position being a position in which the first restricting member is outside the first rotation area and permits the second roller to rotate in the forward rotation direction; an energizing portion that is configured to move between a contact position and a separated position, the contact position being a position in which the energizing portion is in contact with and energizes one of the plurality of the second protruding portions, the separated position being a position in which the energizing portion is more separated from the rotational axis of the second roller than when the energizing portion is in the contact position, the energizing portion also being configured to cause the second roller to rotate in the forward rotation direction when the energizing portion moves to the contact position; a second restricting member that is configured to move between a second restricting position and a second permitting position, the second restricting position being a position in which the second restricting member is in a second rotation area and restricts rotation of the second roller in the forward rotation direction, the second rotation area being an area that the plurality of the second protruding portions move when the plurality of the second protruding portions rotate in the forward rotation direction, the second permitting position being a position in which the second restricting member is outside the second rotation area and permits the second roller to rotate in the forward rotation direction, the second restricting member also being configured to cause rotation of the second roller to stop in a specific rotational position by coming into contact with a specific one of the second protruding portions when the second restricting member reaches the second restricting position, the specific one of the second protruding portions being a different one of the plurality of the second protruding portions than the second protruding portion with which the energizing portion comes into contact; a first actuating portion that is configured to move the energizing portion from the separated position to the contact position, and to subsequently move the first restricting member from the first restricting position to the first permitting position and move the second restricting member from the second permitting position to the second restricting position; and a second actuating portion that is configured to move the second restricting member from the second restricting position to the second permitting position and to subsequently cause the second roller that is rotated by the first actuating portion to rotate farther in the forward rotation direction while maintaining a state in which the second roller is in the clamping position.
