Claims

[Scope of utility model registration request]

In a thermal recording device in which a thermal head is held in a head holder that can be opened and closed, and the head holder is closed and the thermal head is pressed against a sheet of paper for copying or printing, at least a part of the head holder is electrically conductive, and the thermal head is insulated from this. At the same time, the head holder is attached to the conductive part of the main body, and at least the surface of the operating body that manually opens and closes the head holder is made conductive to connect the head holder, the operating body, and the conductive part of the main body with electricity. A thermal recording device characterized by being in a conductive state.
