Abstract
A thermal head (255) is placed on a head block plate (230) cantilevered to a base portion (103) to come into contact with, or separate from, a platen roller (210), and an operating member (260) manually operated Is rotatably provided for this contact or separation. The operating member (260) is designed so that the thermal head (255) is made to abut against the platen roller (210) on the way to the final stage of operation, a spring (270) for pressing the thermal head against the platen roller is biased, and at the final stage, an end (260e) thereof is trapped,into a receiver (190a) constructed integral with the base portion to support a part of the side on which the head block plate (230) is not supported. In this way, the stability of operation and durability are assured.
