Abstract

PURPOSE: To shorten the pirnt timing measurement time by detecting the strike of a printing type hammer, by counting clock signals to a fixed number during a period from the sending of a print instruction until the strike of the hammer, and by displaying its mean value, maximum value and minimum value.
CONSTITUTION: In strike detection circuit A, the print instruction from print control circuit 5 makes printing type hammers 31 to 3n strike piezoelectric element 2 and strike signals are sent from element 2 to FF10, where the period from the sending of the print instruction until the strike of the hammers is stored. Simultaneously, counter 9 for the number of times of printing counts up the number of times of sending the print instruction. Only while clock signals 15 is stored in FF10, AND circuit 14 sends it to mean-value counter circuit B and maximum/minimum counter circuit C. Circuit B counts up clock signals to the fixed number of times and its mean value is displayed on display units 181 to 184. The counter output of circuit C is sent to maximum-value detection circuit D and minimum-value detection circuit, so that the maximum value and mininum value will be displayed on the display units respectively.
