Claims

[Claims for Utility Model Registration] (1) A carriage on which a thermal head is mounted and movable along the platen, and a head assembly that lowers the thermal head in a direction toward the platen or raises it in a direction away from the platen. In a thermal transfer printer equipped with a down mechanism,
The carriage comprises a lower body and an upper body that is movable relative to the lower body and to which the thermal head is attached, and a locking holder that locks and holds the upper body in a predetermined position on the lower body. A thermal transfer printer characterized in that a means is provided. (2) Utility model registration claim (1) characterized by providing a main shaft that guides the carriage in a direction along the platen, and a conversion means that converts rotation of the main shaft into movement of the upper body. Thermal transfer printer described. (3) The thermal transfer printer according to claim (2) of the utility model registration, characterized in that the main shaft is formed into an oval shape in cross section. (4) The thermal transfer printer according to claim (2), wherein the converting means is a cam that is slidably engaged with the main shaft. (5) The locking means is characterized by comprising a groove having a step provided on either the upper body or the lower body, and a pin provided on the other and movably engaging with the groove. A thermal transfer printer according to claim (1) of the utility model registration claim.
