Abstract
PURPOSE: To permit an external operation member enabling the setting to correct both the digital display and the pointer indication on an electronic clock by correcting the time lag due to the maloperation of the external operation members.
CONSTITUTION: When a crown 5 is pulled out by one step, a switch 5a' is closed to allow the frequency division output through AND gates 28 and 29 to cause a buzzer 31 to produce an alarm so that the state of the crown 5 is confirmed. Then, turning the crown 5 causes a switch 5c to be closed to correct the display by a digital display means 2 through a correcting circuit 18 and a switching circuit 17. When the crown 5 is pulled out by two steps, a switch 5b' is closed to correct the indication by a pointer indication means 3. At that time, if the crown 5 is returned to the original position without turning after pulling out by two steps, AND gates 26 and 25 of a maloperation correcting means 32 are turned on to control a zero detecting circuit 20 and an up/down counter 19 so that the time lag of the means 3 during the maloperation of the stem 5 is corrected. The constitution permits a stem set to perform various corrections. Therefore, the burden of the external operation members is lessened.
