Abstract

PURPOSE: To optimize the correction value by giving a weight to a new data when a printing timing is corrected by determining variations of speed for driving a belt from an interval of a type pulse drawn from a running belt.
CONSTITUTION: An emitter pulse is detected with a detector FPD and shaped with a waveshaping device WFS. Then, an interval thereof is measured with an interval measuring device EPM. Where the interval of an emitter pulse is expressed by ti, the interval of the pulse by one before ti-1 and the length of 16 pulses before Ti-1. For example, 15/16 of the value Ti-1 is computed with a calculator DLC. The values of (Ti-1)15/16 and ti are added to make a value Ti. Thus, the value Ti is obtained equivalent to 16 pulses before. Likewise, a value Ti15/16 is computed and added to by the value Ti-1 to obtain a value Ti+1. The valves thus obtained are compared with 16t0 (t0 is the original interval time) to determine whether an excitation starting time should be issued easier or later than a normal time.
