Claims

[Scope of utility model registration request]

The thermal head is equipped with a thermal head that is fixed to a swingable head fixing plate with one end pivoted, and a rubber roller that rotates in a predetermined manner. is a thermal printer that prints visible information on the recording medium based on an input signal,
A rotatable rubber roller having a conductor ring fixed to one end, and a pair of conductor elastic pieces having one end fixed through an insulator and having a flexible portion facing the conductor ring, the pair having spring properties. The conductor elastic piece contacts the conductor ring through the recording medium when the recording medium is wound around the rubber roller, and contacts the conductor ring electrically through the conductor ring when the recording medium is wound around the rubber roller and is not warped. A thermal printer characterized in that the flexible end is connected to the rubber roller and the flexible end is in contact with the rubber roller through another conductor piece or directly when the thermal head is separated from the rubber roller.
