Abstract
Provided is a thermal printer which provides ease of maintenance, such as ease of replacement of the thermal head, and which can shorten the time required for maintenance work and reduce maintenance cost. The thermal printer is one which performs printing on a sheet sandwiched between a thermal head having a heat generating element and a platen roller, and includes a first frame (outer frame) for retaining a printing mechanism including the thermal head and the platen roller; a head support member to which the thermal head is secured; a pressure plate that detachably retains the head support member; a joining member for joining the head support member and the pressure plate together; a support shaft (shaft) passed through a shaft hole provided in each of both side walls of the first frame, the support shaft rotatably supporting the head support member; a second frame (lock arm) which is rotatable integrally with the pressure plate about the support shaft; and an urging member suspended between the pressure plate and the second frame, for generating a pressing force between the thermal head and the platen roller in a state where the head support member is joined to the pressure plate.
