ABSTRACT:
A thermal printer comprises a pair of fixed frames for rotatably supporting a platen which is rotated by a motor and a head unit rotatably supported by the fixed frames through a pair of movable frames and for supporting a thermal head. A pair of pinch rollers are rotatably mounted on the fixed frames, which are selectively brought to a first operating state to feed a paper sheet to the region between the platen and the thermal head, and a second operating state to feed no paper sheet. The thermal head is selectively moved between a first position, in which it is pressed against the platen, and a second position in which it is disengaged from the platen. The thermal head is moved to the first position, at the same time the pinch rollers and moved to the second operating state, while the thermal head is moved to the second position, at the same time the pinch rollers are moved to the first operating state.
