Claims

[Scope of utility model registration request]

A line-type thermal head that prints on recording paper on a platen roller, a print control section that controls energization of a plurality of resistors that make up the thermal head, a motor that rotationally drives the platen roller, and a an FG detection section that detects the rotational speed; a motor drive control section that controls the rotational speed of the motor based on a signal from the FG detection section; and a motor drive control section that controls the printing control section and the motor based on the signal from the FG detection section. In a thermal transfer printing device equipped with a mechanical control unit that controls the control unit, a fixed pattern generator that generates a fixed pattern for test pattern printing and a fixed pattern generator that is set to 1/m (m: positive integer) for normal printing. is,
When printing the test pattern, the frequency division ratio is n/m (n:
a frequency divider set to a positive integer); a first switch that switches the input signal to the print control unit between normal printing and test pattern printing;
By providing a second switch that switches the frequency division ratio of the frequency divider between normal printing and test pattern printing, when printing a test pattern, the print line pitch in the sub-scanning direction can be changed to the normal printing. A thermal transfer printing device characterized by having a function of printing at a uniform level density at an integral multiple of .
