Title: Thermal printer
Inventor: KISHINO YASUKAZU
IPC: B41J2/345
Filed: 1985-02-26
Abstract: PURPOSE:To prolong the life of a thermal printer and increase printing speed and quality by positioning the second thermal head which receives the same printing signal as a printing signal received by the first thermal head at constant delayed time interval at the rear of a carrier proceeding direction. CONSTITUTION:Printing is performed by shifting a carrier 1 to the left. The first thermal head 3 melts ink of an ink ribbon 11 which in turns sticks to paper 10. Next, the second thermal head 4 melts ink of an ink ribbon 11 which in turn adheres to paper 10. That is, if coarse paper having 30' or less of Beck's smoothness is used, ink will not be in short supply and printing quality can be improved because printing is performed twice. In this case, an electric current applied to a single thermal head 3 or 4 has only to be small, thus increasing its life. Thus, it is made possible to accelerate the printing speed by increasing printing density because printing is done twice.
