ーマルヘツド移動装置。 A pressure spring that presses the thermal head against the platen is disposed on the back of the thermal head, and this pressure spring is supported by a pressure lever that can be rotated by a cam, and the spring force of the pressure spring is applied by rotating the pressure lever. In a thermal head moving device for a thermal printer, one end of a return spring that stores and urges the thermal head in a direction away from the platen is connected to the thermal head, the other end of the return spring being connected to the pressing lever. A thermal head moving device for a thermal printer, characterized in that:
