Abstract

PURPOSE: To cause print hammers of all digits to reach a type drum face at the same time, by correcting the operation start time of each print hammer according to the length of the flight time.
CONSTITUTION: In the measure mode, the print signal is input to magnet driver 3, and piezoelectric element 9 detects the strike of hammer 1. Meanwhile, the print signal is detected by print signal detecting circuit 15. The output of circuit 15 is switched by switching circuit 7 and is given to flight time counter 8. Counter 8 counts clocks CLK by the start pulse output from circuit 15 and stops counting by the signal from element 9. The difference between contents of counter 8 and constant 12 is calculated by subtracting circuit 11 and is stored in constant memory circuits 14-1W14-n successively. Next, in the operation mode, the output of circuit 5 is input to timing correcting circuit 21 to start counting. When contents of circuit 14 agree with the count value of counter 21, the agreement output is input to correction print signal generating circuit 22, and the correction print signal is sent to driver 3.
