PURPOSE:To surely output the desired number of pulse trains for a prescribed period by making a revision processing for a numeral deciding the period time of the pulse train outputted from a timer means coincident with the interruption processing operation of a microprocessor. CONSTITUTION:The microprocessor 10 has software assinged with a processing sending a numeral corresponding to the period time of an output pulse train to a timer section 30 and a processing signifying the start of execution of the processing operation of the microprocessor as the interruption processing operation of the microprocessor 10. Thus, the operation period of the microprocessor 10 is decided by a period of a prescribed period signal 50 and the period time for the numeral revision processing is decided similarly. Thus, in the operation calculating the output pulse period time M when a pulse train comprising n-set of pulses is desired to be outputted during the prescribed period time, since the prescribed period time is equal to the period time of the numeral revision processing, the pulse train ensuring the pulse number of (n) outputted for the prescribed period time is outputted.
