摘要： A thermo-sensitive recording apparatus individually controls the energization level of each of a plurality of heater elements formed on a substrate and constituting a thermal print head. In generating each energization level, the present and previous status of an individual heater element and selected neighboring elements are taken into consideration. Other factors combined in a selectively weighted manner include the latent heat of the individual heater element and its neighboring heater elements, the resistance of the heater element, the percentage of heater elements to be activated during the printing of a line, and the temperature of the substrate.

摘要： A thermal head drive circuit with the input connected to a source of printing data and the output connected to a thermal head including heater elements, so as to improve the picture quality of a thermal head recording apparatus for printing successive lines. Improved picture quality is effected by using data from previously printed lines to compute a corrected pulse energy for the line being printed. The circuit uses a heat storage state operator for operating the heat storage state of each of the heater elements constituting a thermal head, a pulse energy operator for computing a printing pulse energy to be applied to each of the heater elements, a memory for storing the electrical pulse energy used in the previously printed line, and a counter to count the number of dots on the line to be printed. The pulse energy operator uses data from the heat storage state operator, the counter, and from the memory which has data on the pulse energy used in previously printed lines. The output of the pulse energy operator is connected to a pulse generator which is used to drive the heater elements of a thermal head.
