  • Thermal printer
    Publication number: 20010001273
    Abstract: A thermal printer is provided. The thermal printer includes a thermal head module, a platen module, and a gear module. The platen module and the gear module are connected to the thermal head module. When setting a recording sheet to the printer, the operator lifts up a knob provided to the platen module, so that the platen module is rotated counterclockwise around a pin provided to the thermal head module. In this manner, the platen separates from the thermal head, and setting a recording sheet becomes easier.
