A paper tractor unit is disclosed. The tractor unit which is movably provided for a support member can be selectively moved between a position at which a continuous paper is fed and a position from which the paper is drawn, a paper drawing drive roller and a pinch roller being provided at the position from which the paper is drawn. A release lever is provided which moves in synchronization with a switching position to the position from which the paper is drawn. A pinch roller and a guide shaft are provided for a support plate which is capable of being moved by the release lever. The pinch roller can come into contact with the paper-drawing drive roller and move away from the same. The guide shaft can freely move along a guide portion in a direction in which the pinch roller comes into contact with and moves away from the drive lever. A guide pin is a pinion and a rack is formed on the guide portion for the purpose of engaging with the pinion.
