A conventional thermal printer has had a structure in which a platen roller cannot be removed from a frame. Therefore, it has been necessary to insert a printing paper between a thermal head and the platen roller. Thus, it has been hard to load the printing paper. In order to solve the problem, there has been devised means for engaging the platen roller with the frame by the biasing force of the thermal head pressing the platen roller to forcibly lift up the platen roller, thereby removing the platen roller. However, there have been problems in that great operating force is required for the removal and the precision in a platen roller support position is low. A frame is provided with a slit (1c) having such a shape as to guide a bearing of a platen roller (2), and the bearing of a platen roller (2) is pushed against the slit by a lock arm using the biasing force of a pressure spring (8) for causing a thermal head (5) to come in press-contact with the platen roller (2). Consequently, the platen roller (2) is supported.
