Abstract
The thermal transfer printer of the present invention is provided with a cam follower mounted on a thermal transfer head in one body and an eccentric cam, which is controlled within a semicircle so as to be positioned at either a first position for releasing it from the cam follower to press the thermal transfer head to a platen or a second position for pressing it to release the thermal transfer head from the platen, as a construction for pressing the thermal transfer head to the platen and releasing the thermal transfer head from the platen, whereby the mechanism for pressing the thermal transfer head to the platen and releasing the thermal transfer head from the platen itself can be remarkably small-sized and is simple in action due to its remarkably small working quantity, the printer can be small-sized as a whole and improved in reliability of operation as well as durability. Furthermore, the thermal transfer printer can be stably carried out the subsequent controls after initial powering, since the positional relation between the thermal transfer head and the platen is controlled so as to be initially set to the predetermined relation without delay when it is initially powere…
