Claims

[Claims for Utility Model Registration] 1. Thermal ink in which heat-melting pigments of multiple colors are applied separately in the feeding direction between printing paper mounted on a platen and a thermal head that is moved relative to the printing paper. In a thermal transfer color printer in which a ribbon is arranged and the pigments of the thermal ink ribbon are selectively thermally transferred to the printing paper, the type of each pigment is detected and the detection signal is used to control the feeding of the thermal ink ribbon. an auxiliary color sensor that is provided adjacent to the main color sensor and detects at least a predetermined type of pigment in the thermal ink ribbon; 1. A thermal transfer color printer, comprising: a detection means for detecting positional deviation of a thermal ink ribbon. 2. The thermal transfer type color according to claim 1, wherein the auxiliary color sensor is provided adjacent to and spaced from the main color sensor in the feeding direction of the thermal ink ribbon. printer. 3. The thermal transfer color printer according to claim 1, wherein the auxiliary color sensor comprises a green or yellow light emitting diode and a phototransistor that receives light from the light emitting diode. 4. The thermal transfer color printer according to claim 1, wherein the detection means is configured to issue an alarm when a positional shift of the thermal ink ribbon is detected when the power is turned on. .
