Abstract

PURPOSE: To arrange so that the size of a print character may be changed with the moving speed of a heated fixed, by providing a character size control circuit to change a pulse width per print character size in a character pattern control part which outputs a dot pulse corresponding to a character pattern.
CONSTITUTION: A character size control circuit 17, based on a small (large) character signal to be input from an input means 14, transmits a dot pulse A which corresponds to a dot pattern sent from a character pattern control circuit 16 and has a small (large) pulse width to a gate circuit 20. In addition, a density adjustment circuit 19, animated by a small (large) character signal which is input from an input means 14, transmits a pulse B for density adjustment having a small (large) pulse space to the gate circuit 20, taking "AND" of the both pulses. Then the density adjustment circuit 19 transmits "AND" to a head drive part 11 as a gate pulse C. Through this process, a character dot of small (large) character of D signal is printed.
