囲第１項または第２項記載の熱転写プリンタ。[Scope of Claim for Utility Model Registration] (1) A carriage equipped with a thermal head facing the paper on a platen is disposed so as to be movable along a support shaft and rotatable around the support shaft. A thermal transfer printer in which a carriage is rotated around the circumference to bring the thermal head into contact with and away from the paper, and the carriage is moved along a support shaft by a motor, includes a pin that is rotatable in conjunction with the carriage; A cam structure with multiple paths into which the pin fits is formed on the side surface, and a first external tooth with a toothless portion on a part of the circumference and a second external tooth with teeth on the entire circumference are formed on the outer peripheral surface. a cam gear formed in the cam gear; a first drive gear that transmits the drive of the motor to the cam gear via the first external teeth; and a first drive gear that is in frictional contact with the first drive gear and meshes with the second external teeth of the cam gear. The cam mechanism of the cam gear can be set to a position where the thermal head on the carriage is in pressure contact with the paper and a position where it is separated from the paper, and the pin is partially oriented in one direction. A thermal transfer printer characterized in that it is formed so that it can move only. (2) The thermal transfer printer according to claim 1, wherein the pin is spring-biased in a protruding direction, and the cam mechanism is formed with a plurality of steps to prevent the pin from moving backwards. . (3) The thermal transfer printer according to claim 1 or 2, wherein the cam mechanism at the portion where the pin fits when the thermal head assumes a position where it presses against the paper is formed to have a wide width. .
