ABSTRACT:
Provided is a head support structure including: a thermal head (11) for heating a sheet material (5); a platen roller (12) for transporting the sheet material (5) being pressed by the thermal head (11); a head support member (13) for supporting the thermal head (11), which is capable of moving in a direction in which the head support member (13) is brought into close contact with or moved away from the platen roller (12); and a head biasing member (14) for biasing the head support member (13) to a side of the platen roller (12). Further, the head biasing member (14) is formed of an elastic material and includes a pressing part (14a) for pressing the head support member (13) against the side of the platen roller (12) and holding parts (14b) provided at each end of the pressing part (14a), for holding the platen roller (12). Accordingly, a structure of the head support structure is simplified and an entire apparatus to which the head support structure is mounted can be downsized.
