PURPOSE:To simplify the operability, by touching a touch switch direct with a finger to input in a plane where a pointer turns. CONSTITUTION:When a touch switch 3 is pressed, a time correction mode enters through detection 4 and signal selection circuits 8 and 9 shift to a path of a hour-hand counter 12 and a hour-hand motor 15. Subsequently, as an input of a touch switch 1 is detected with a touch position detecting circuit 2, the touch position is sent to a comparator circuit 7 to obtain a difference between the position value and a value of the counter 12 and the results are outputted to a motor 15 and the counter 12 to move a hour hand to the position where a finger touched to correct. Then, upon the touching of the switch 3, the circuits 8 and 9 shift to the path having a min-hand counter 11 and a min-hand motor 14. Here, as an input of the switch 1 is detected with the circuit 2, a min. hand is moved to a position where a finger touched to correct. After the hour hand and min. hand were corrected, the switch 3 is touched again. The operation returns to the normal time mode and a signal of a frequency dividing circuit 6 enters the counters 10-12 and the motors 13-15 to count the time as usual. |
