Abstract

PURPOSE: To prevent the dispersion of printing timing from occurring unpunctually and to improve the printing quality by a method wherein the dispension of printing timing in an impact printer is detected by a piezoelectric converter arranged in parallel to types and driven by signals obtained for correction.
CONSTITUTION: A printing instruction signal is inputted into the driving circuit of electromagnets to operate 160 sets of electromagnets 4, movable levers 3 and hammers 21. When a hammer 21 strikes the surface of a type, an impact current occurs in a piezoelectric converting element 81 arranged in parallel to a type 11 and runs in a coil 85 to generate a magnetic field in a core 84 concentric with the drum 1. At that time an induction field appears in a pick-up 87 arranged near the core 84 to induce a current in an induction coil 86. Thus, the time until each hammer 21 operates respectively every position and strikes is computed and respective differences of time are searched. The dispersed values obtained are adjusted for correction so that timings of signals imputted to the driving circuit can be arranged and printed on the basis of the average time.
