Ink ribbon tension control unit of thermal printing color printer

摘要

(57) Abstract Objective To guarantee the effective print area widely, still aroundTemperature changing, the gap between each color ink is the hoThe do try not to be generated. Constitution Relative vis-a-vis thermal head 7 pushing pressure separationTo have the platen roller 8 which between is done, thermal head 7With thermal energization and the relative pushing pressure of platen roller 8, iTranscribing the ink which was applied to nkuribon 20 to print form 2In the thermal transfer printer which is done, ink ribbon 20Drawing out from delivery roller 20, thermal head 7With to supply with print forms 2, to coil roller 22 windingIn order to take, it constitutes, detecting the ambient temperature with temperature sensor 40It does, it supplies to the DC motor 49 Drive coil roller 22In the temperature which is detected ru voltage, by temperature sensor 40 the basic zuBeing, it controls.
