Document Type and Number:
Japanese Patent JP3229256
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a thermal head in which a thermal body developing different colors depending on the heaving temperature can be provided with different heating temperatures at the time of concurrent scanning.
SOLUTION: The thermal head comprises a first strobe signal input means performing the heating control of a heating means 1 corresponding to first energy, a second strobe signal input means performing the heating control of the heating means 1 corresponding to second energy, a first heating time control means for controlling the heating of the heating means based on the first strobe signal depending on the presence/absence of a print data within a print control range under control of the first energy, and a second heating time control means for controlling the heating of the heating means based on the second strobe signal depending on the presence/absence of a print data within a print control range under control of the second energy.
