<p>PURPOSE:To secure the uniformity and the precision of a processing, by executing the correction plural times for an overall correction quantity and correcting a unit correction quantity every one step of the correction. CONSTITUTION:In the conventional device, a timer correcting part 6 is connected to a timer processing mechanism 4. In case that the time in a computer which is slow is set forward, a unit correction quantity is subtracted from the preset value of a timer processing mechanism 3 to generate a driving signal 13 for the elapse of T-(the unit correction quantity) to the required time T of time counting, and thus, the current time in the computer is set forward by the unit correction quantity. In case that the time in the computer which is fast is set backward, the preset value is added to the unit correction quantity to generate the driving signal 13 for the elapse of T+(the unit correction quantity) to said required time T, and thus, the current time in the computer is set backward by the unit correction quantity.</p> |
