Abstract
PURPOSE: To adjust printing pressure easily according to the blank in an impression printer like a dot printer and the like by a method wherein printing pressure is adjusted by a means to change the quantity of electricity supplied to an electromagnetic solenoid.
CONSTITUTION: If a solenoid operating signal is inputted to an input terminal, the output of an inverter takes a high level, and electric current passes through a driver transistor 2 and begins to be supplied to an electrical solenoid I1. Then, since the voltage between both ends of a resistor 31 increases gradually, the voltae and the standard voltage of a standard voltage setting device 7 are compared through a comparator 6, the voltage between both ends are composed and the quantity of electricity to the solenoid I1 is controlled. The quantity of electricity to the solenoid I1 or the magnitude of the driving force of the printing head is proportional to the printing pressure and, therefore, the printing pressure is adjusted by adjusting the standard voltage outputted by a variable resistance 11 in the standard voltage setting device 7.
