Reset circuit 25 is constituted gate circuit, a counter, etc., together comprising a chattering prevention circuit detects that the crown switch (reset switch) 24 is operated, the frequency dividing circuit 12, the mode control circuit 22 and the timer 23 Reset processing is performed.
The needle aligning unit 50 is configured by a crown, a needle aligning wheel train, etc., and the pointer position is adjusted to a desired time by the user, and the crown switch 24 is turned on / off in conjunction with the operation of the needle aligning unit 50. It will be done.

[0037]
Next, with reference to the timing chart of FIG. 3, the time setting process of the analog electronic timepiece according to the first embodiment of the present invention will be described more specifically.
In the process of setting the time, first, the operator pulls the crown of the needle aligning unit 50 at the moment when the second hand reaches the 0 second position, turns the crown switch 24 ON, and pushes the crown of the needle coupling unit 50 OFF. Repeat the state setting operation three times consecutively. As a result, a crown signal as shown in FIG. 3 (d) is generated.
At this time, the divider circuit 12, the mode control circuit controller 22, and the timer 23 are initialized by the reset circuit 25 in synchronization with time t1 at which the crown is first pulled in the needle alignment unit 50 and the crown switch 24 is turned on. After being reset, as shown in FIG. 3C, the ENABLE signal rises and maintains the "H" level for a predetermined time (in this example, one second until time t3).
Then, if the time t2 of the third depression of the crown (the OFF operation of the crown switch 24) is earlier than the falling time t3 of the ENABLE signal, the analog electronic timepiece 10 is synchronized with the time t2 as shown in FIG. It becomes adjustment mode. In this case, if the time t2 is later than the falling time t3 of the ENABLE signal, the analog electronic timepiece 10 does not enter the adjustment mode, ends the process, and returns to the normal clocking operation.

[0040]
That is, the operator first pulls the crown in the needle aligning unit 50 at the moment when the second hand reaches the 0 second position, turns on the crown switch 24 and stops the second hand at the 0 second position (time t1).
Next, the crown of the needle aligning unit 50 is operated such that the state of the crown switch 24 of the analog electronic timepiece 10 appears three times, that is, OFF / ON / OFF / ON / OFF and the OFF state. Then, it is determined whether three times of the turning off operation of the crown switch 24 have been performed within one second.
At this time, in synchronization with the first OFF operation (time t1 '), the timer 23 sets the ENABLE signal of the mode control circuit to "H" level for one second from time t1' to time t3 '. Then, when the OFF operation is performed three times within this one second, the analog electronic timepiece 10 is in the adjustment mode.

The data control circuit 27 includes a gate circuit, a latch circuit, and the like, acquires a correction data signal transmitted from an external adjustment device 30 'described later via the motor coil 15 and the receiving circuit 21, and It converts into correction data under management and outputs it to the storage circuit 28. The storage circuit 28 is a non-volatile memory such as an EEPROM and stores the correction data. Pace adjustment circuit 29 controls the frequency dividing circuit 12 based on the correction data stored in the storage circuit 28, and performs pace adjustment.
FIG. 6 is a block diagram showing the configuration of the external adjustment device 30 'used in the second embodiment of the present invention. In the external adjustment device 30 'shown in FIG. 6, the same parts as those of the external adjustment device 30 according to the first embodiment described above with reference to FIG. I omit it.

[0046]
When the adjustment mode signal is received from the external adjustment device 30 'in the reception standby state of the adjustment mode signal (Y in step 3), the process proceeds to step 4.
Next, it is determined whether or not an adjustment signal has been received within a fixed period (after the crown switch 24 is turned on) after the crown is pulled in the needle alignment unit 50 in step 1 (step S4).
If step 4 is Y, the process proceeds to step S5.
When step S4 is Y, when the crown is pushed in the needle alignment unit 50 and the crown switch 24 is turned off (step S5), the analog electronic timepiece 10 'shifts to the adjustment mode (step S6).
In this case, the usual analog electronic timepiece is initialized by pushing the crown in the needle alignment unit 50, and the divider circuit is initialized, and the motor drive pulse is output after 1 second to start the hand movement. The analog according to the present embodiment In the electronic timepiece 10 ', once shifting to the adjustment mode, the output of the motor drive pulse is not resumed even if the crown is pulled or pushed again in the needle alignment unit 50, and the adjustment mode is maintained. The operation of setting the hour hand and the minute hand to the predetermined time, which is previously performed in step S2, may be performed after shifting to this adjustment mode.

Here, the ENABLE signal shown in FIG. 7D maintains the "H" level for a predetermined time (one second until time t2 in this example), and during this period, the analog electronic watch 10 'is in the adjustment mode from the external adjustment device 30'. Transition to the signal reception standby state.
Then, in the reception standby state of the adjustment mode signal, the adjustment mode signal (see FIG. 7C) generated by the mode signal generation circuit 33 of the external adjustment device 30 ′ and transmitted via the transmission circuit 34 and the coil 35 is When the analog electronic timepiece 10 'receives through the motor coil 15 and the receiving circuit 21 and then the crown is pushed at time t3 in the needle alignment unit 50 (when the crown switch 24 is turned off), the analog electronic timepiece 10' Shifts to the adjustment mode (see FIG. 7 (f)).
When the analog electronic timepiece 10 'shifts to the adjustment mode, the rate measurement pulse generation circuit 26 generates a rate measurement pulse from the reference pulse signal currently generated by the divider circuit 12 according to the command of the mode control circuit 22 and drives it. The signal is transmitted to the external adjustment device 30 'for a fixed time through the pulse generation circuit 13, the motor driver 14, and the motor coil 15 (see FIG. 7A). Here, the rate measurement pulse is a short pulse (for example, 0.244 msec) that does not cause the motor to rotate, and the cycle is proportional to the oscillation frequency of the oscillation circuit 11.

[0051]
The external adjustment device 30 ′ receives the rate measurement pulse at the reception circuit 37 via the coil 35 and outputs the pulse to the rate measurement circuit 38. The rate measuring circuit 38 measures this rate measuring pulse, compares it with the correct rate pulse, and outputs an error signal to the correction data generating circuit 39.
The correction data generation circuit 39 generates rate correction data under the control of the control circuit 32 based on the error data, and outputs the rate correction data to the correction data signal generation circuit 40. Then, the correction data signal generation circuit 40 generates a correction data signal used for transmission based on the generated rate correction data, and outputs the correction data signal to the transmission circuit 34.
The transmission circuit 34 transmits the correction data signal to the analog electronic timepiece 10 ′ via the coil 35. The analog electronic timepiece 10 'receives the correction data signal at the reception circuit 21 through the motor coil 15 (see FIG. 7C), and outputs the correction data signal to the data control circuit 27. Then, the data control circuit 27 writes the correction data to the storage circuit 28 under the control of the mode control circuit 22.
Pace adjustment circuit 29 controls the frequency-dividing circuit 12 on the basis of the correction data in the memory circuit 28 is stored, performs pace adjustment.
