Abstract
A thermal printer allows ink ribbon replacement without interference of a hook positioned in the opened state particularly in an ink ribbon replacement operation. A thermal printer includes a head lock leverwhich includes a hookat the tip of the lever. The hook is mounted such that it can be moved in the longitudinal direction relative to a turn shaftduring turning of the turn shaft, allowing the distance between the turn shaftand the hookto be changed. A movement control moves the head lock leversuch that the distance between the turn shaftand the hookin the opened state in which the thermal headis separated from the platen rolleris smaller than that in the pressed state in which the thermal headis pressed into contact with the platen roller
