PURPOSE:To enable to easily carry out the correction of difference in time continued to that of time, by dividing into the correction period and correction signal generation stop period by operating the time division of switch operation period and also, generating the correction signal having a different speed in accordance with the period. CONSTITUTION:When a correction switch 14a of a correction device 14 is continued to close through an outer part operation parts 14b, time division of closing period is operated by a split circuit 11f of an electron circuit 11. Then, output of a dividing circuit 11b is selected through a correction signal generating circuit 11g and different correction signal is added to a step motor 12 becoming higher speed at every time division period putting between the time division stop period in which the correction signal generation is stopped. Accordingly, when the sum of output number of different correction signal becomes a definite value by the circuit 11g, definite correction of difference in time is easily, surely and automatically operated continued to the time correction by stopping the output of the correction signal even when a switch is made ON state. |
