Abstract

PURPOSE: To adjust a flight time without using high grade technology and losing much time by a method wherein regarding the flight of a printer hammer to be adjusted an average value measured is compared with a reference value and a motor driver is driven by the differential value to be adjusted.
CONSTITUTION: By a test operation instruction from CPU11 the printer hammer for the 1st figure of a line printer performs printing operation the flight time is measured and stored in a memory 12. An average value of a plurality of measured values is found in the CPU11, compared with a reference value. A pulse signal and a figure number of the printer hammer are outputted according to the deviated value. After the pulse signal is amplified by a conversion circuit 31, the motor 42 of a motor driver 4 is driven by the number of pulses through a motor drive circuit 32, a shaft body 41 matched with an adjust screw is revolved by a necessary amount and adjusted. The number of the figure is displayed on a digital display 43 through a display drive circuit 33. A figure on or after the 2nd figure also is adjusted in the same way.
