Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a thermal transfer recording device, and more particularly to a thermal transfer recording device in which the pulse width for driving a thermal head for printing on a memory stack paper is determined based on various conditions.

[Conventional technology]

Conventional thermal transfer recording devices determine the pulse width for driving the thermal head by storing data on the printing pulse width corresponding to the printing cycle and the temperature data of the thermal head in the memory in the form of a table, and determining the pulse width for driving the thermal head. The print density transferred from the recording paper to the recording paper was controlled to a predetermined value at each printing cycle and at each temperature.

[Problem to be solved by the invention]

The conventional thermal transfer recording device described above does not perform control using environmental temperature data of the transfer film and recording paper, so the print density on the recording paper does not reach a predetermined value, which occurs when continuous recording is performed. There are disadvantages in that it is not possible to fully control the effects of reverse transfer, and in that it is impossible to maintain a predetermined print density if a transfer film and recording paper other than those specified are used.

[Means to solve the problem]

The thermal transfer recording device of the present invention includes a thermal head in which a plurality of heating resistors are arranged in parallel, a transfer film and a recording paper that are printed and transferred by the thermal head, and a first recorder that shows the characteristics of the transfer film and recording. a means for outputting second data; a means for outputting third data of the environmental temperature at which the transfer film and recording paper are used; and a means for outputting correction data using the first, second and third data. a means for storing reference pulse width data for driving the heating resistor in accordance with the temperature of the thermal head; and a means for correcting the reference pulse width using the correction data and outputting the corrected reference pulse width. ing.
