2. Description of the Related Art In a conventional analog electronic timepiece, which is an electronic device, data required for calculating temperature correction data is measured in a circuit block or a movement state. Specifically, the oscillation frequencies of the oscillator and the temperature sensor built in the analog electronic timepiece are measured at three or more different temperatures, and the temperature correction data is calculated based on the measurement results.

However, in the above-described conventional example, when the circuit block is incorporated into the movement or when the movement is incorporated into the exterior,
Oscillation frequencies of the oscillator and the temperature sensor shift due to changes in stray capacitance and stress, and the rate adjustment based on the temperature correction data becomes inaccurate. As a result, there has been a problem that the accuracy and yield of the analog electronic timepiece are deteriorated. In addition, when data is exchanged between an adjustment device that calculates temperature correction data and the like and a circuit block or movement, contact points between the adjustment device and the block or movement are extremely small.

In the case of one adjusting device, only one analog electronic timepiece could calculate the temperature correction data at a time. As a result, temperature correction data for a plurality of analog electronic timepieces cannot be calculated at the same time, resulting in a problem that work efficiency is poor. Further, in the case of an electronic device having a program for controlling a process for calculating temperature correction data, the control program which is used only once before shipment is usually kept as it is after shipment. . As a result, there is a problem that the memory storing the program is wasted.

And a reset unit 27 for detecting the operation of the frequency divider 6 and resetting the frequency dividing unit 12. Here, during the temperature correction data calculation process, the measuring unit 24 controls the external coil and the motor coil 14.
The respective oscillation frequencies of the oscillation unit 11 and the temperature-sensitive oscillation unit 16 are measured based on an external reference signal that is input by electromagnetic coupling, and during normal operation, the output signal of the oscillation unit 11 is used as a reference. The oscillation frequency of the temperature-sensitive oscillation unit 16 is measured.

[1.2] Operation of First Embodiment Next, the operation of the first embodiment will be described with reference to FIGS. FIG. 2 shows an operation processing flowchart, and FIGS. 3 and 4 show operation timing charts.
First, the control unit 21 of the analog electronic timepiece 10 sets “1” to a variable n set to repeat measurement of data necessary for calculating temperature correction data by a predetermined number of times ( Step S1). Next, in the control unit 21, the external coil and the motor coil 14
A reception signal from the outside that is input by electromagnetic coupling is received via the reception unit 20, and it is determined whether or not the reception signal is a signal indicating a start signal (step S2). If it is determined in step S2 that the received signal is not a signal indicating the start signal (step S2; No), the determination is repeated. In the actual adjustment, the analog electronic timepiece 10 is put in a constant temperature bath or the like, and when the temperature becomes constant at a predetermined temperature, a start signal from the outside is input.

On the other hand, if it is determined in step S2 that the received signal is a signal indicating the start signal (step S2; Yes), the control unit 21 prohibits the generation of the driving pulse output for performing the hand movement. (Step S9). Next, the measuring unit 24 measures the oscillation frequency from the oscillation unit 11 based on the reference oscillation signal generated by the oscillation unit 11 and a reference signal that is a received signal from the outside (step S3). Specifically,
As shown at time t1 in FIG. 3, when the received signal is a signal indicating a start signal (see FIG. 3B), at time t2, the control unit 21 outputs the oscillation unit frequency measurement signal to “ H level (see FIG. 3C). Then, while the oscillation unit frequency measurement signal is at the “H” level (between time t2 and time t3 in FIG. 3), the measurement unit 24 uses the reference oscillation signal generated by the oscillation unit 11 and the received signal from the outside. A reference signal (FIG. 3)
(See (b))) to measure the oscillation frequency from the oscillation unit 11.

Next, the measuring means 24 measures the oscillation frequency from the temperature-sensitive oscillating unit 16 based on the output oscillation signal generated by the temperature-sensitive oscillating unit 16 and a reference signal which is a received signal from the outside ( Step S4). Specifically, at time t3 shown in FIG.
Sets the oscillation unit frequency measurement signal to the “L” level (see FIG. 3C).
The measurement of the oscillation frequency from 1 is completed. At the same time,
The control unit 21 sets the temperature-sensitive oscillation unit frequency measurement signal to the “H” level (see FIG. 3D). And
While the temperature-sensing oscillation unit frequency measurement signal is at the “H” level (between time t3 and time t4 in FIG. 3, except for n = “3” to be described later, time t3 to time t5 in FIG. 4). In the meantime, the measuring unit 24 oscillates from the temperature-sensitive oscillation unit 16 based on the output oscillation signal generated by the temperature-sensitive oscillation unit 16 and a reference signal (see FIG. Measure the frequency.

Then, the control unit 21 releases the prohibition of the generation of the drive pulse (step S10). Next, the control unit 21 determines whether the variable n is a numerical value indicating a predetermined number of times (step S5). FIG.
In the example, "3" is set as a numerical value indicating a predetermined number of times. In the determination of step S5, if the variable n ≠ “3” (step S5; N
o), "1" is added to the variable n (step S8), and the process proceeds to step S2. In the actual adjustment,
When the analog electronic timepiece 10 is brought into a constant temperature state by a predetermined temperature different from the previous time, an external start signal is input. On the other hand, in the determination in step S5, the variable n
= "3" (Step S5; Yes), the arithmetic unit 25 calculates the oscillation frequency from the oscillation unit 11 measured in Step S3 and the oscillation frequency from the temperature-sensitive oscillation unit 16 measured in Step S4. (Step S).
6). Specifically, at time t5 shown in FIG. 4, the control unit 21 sets the temperature-sensitive oscillation unit frequency measurement signal to the “L” level (see FIG. 4D), and
Ends the measurement of the oscillation frequency from the temperature-sensitive oscillation unit 16. At the same time, the control unit 21 sets the correction data calculation signal to the “H” level (see FIG. 4E), and the arithmetic unit 25 measures the oscillation frequency from the oscillation unit 11 measured in step S3 and the oscillation frequency measured in step S4. Temperature correction data is calculated based on the oscillation frequency from the temperature-sensitive oscillation unit 16 (step S
6). The calculation of the temperature correction data will be described later.

Next, the temperature correction data calculated by the arithmetic unit 25 is written into the storage unit 22 under the control of the control unit 21 (step S7). Specifically, at time t6 shown in FIG.
1 sets the correction data write signal to the “H” level (see FIG. 4F), and writes the temperature correction data calculated by the arithmetic unit 25 to the storage unit 22.

Here, the calculation of the temperature correction data will be briefly described. FIG. 5A shows the temperature characteristic of the oscillation unit,
FIG. 5 (b) is a temperature characteristic of a temperature-sensitive oscillation unit as a temperature sensor, and FIG. 5 (c) is a schematic flowchart of temperature correction data calculation processing. First, the rate in FIG. 5A is obtained by the following equation. Rate = k * (fh-fr) / fr where fh is the oscillation frequency of the oscillation unit 11, fr is an ideal reference frequency of fh, k is a constant for converting the frequency into the rate, and k = 86,400 [sec]. (= 24 * 60 * 60 [sec]). As described above, the rate of the analog electronic timepiece 10 depends on the oscillation frequency output from the oscillation unit 11 and the oscillation unit 1.
The oscillation frequency can be obtained from the reference frequency which is an ideal value of the oscillation frequency output from the reference frequency. When calculating the temperature correction data, first, the analog electronic timepiece 10 is kept at the temperature T1 for a predetermined time (for example, 3 hours). f
1 and the rate y1 of the analog electronic timepiece 10 are measured (step S11). Next, the analog electronic timepiece 10 is set to the temperature T2.
After a predetermined time (for example, 3 hours), the oscillation frequency f2 of the temperature-sensitive oscillation unit 16 and the rate y2 of the analog electronic timepiece 10 are measured when the temperature becomes constant (step S12). Subsequently, the analog electronic timepiece 10 is maintained at the temperature T3 for a predetermined time (for example, 3 hours), and when the temperature becomes constant, the oscillation frequency f3 of the thermosensitive oscillation unit 16 and the rate y3 of the analog electronic timepiece 10 are measured ( Step S13). Thereafter, unique values (coefficient β ′, reference frequency ft, reference rate y0) of the analog electronic timepiece 10 satisfying all of the following equations (1) to (3) are calculated, and the coefficient β ′, the reference frequency ft, The reference rate y0 is stored in the storage unit 22 of the analog electronic timepiece 10 as temperature correction data (step S14). y1 = −β ′ (f1−ft) ² + y0 (1) y2 = −β ′ (f2−ft) ² + y0 (2) y3 = −β ′ (f3−ft) ² + y0 (3) )

The process of actually adjusting the rate by temperature correction based on the temperature correction data calculated as described above will be described below. First, the oscillation frequency fk of the temperature-sensitive oscillation unit 16 is determined by the measurement unit 24. Next, the temperature correction unit 17 substitutes the oscillation frequency fk of the temperature-sensitive oscillation unit 16 and the temperature correction data (coefficient β ′, reference frequency ft, reference rate y0) stored in the storage unit 22 into the following equation. Then, the rate y of the oscillation unit 11 is obtained. y = −β ′ (fk−ft) ² + y0 Then, the temperature correction unit 17 controls the frequency dividing unit 12 based on the calculated rate y of the analog electronic timepiece 10 to output from the oscillation unit 11. Adjust the reference oscillation signal.

[1.3] Effects of the First Embodiment As described above, according to the first embodiment, data is received from the adjustment device via the motor coil 14 of the analog electronic timepiece 10. This makes it possible to perform the measurement of the data necessary for calculating the temperature correction data in the movement state or in a state where the movement is incorporated in the exterior, and thus it is possible to improve the accuracy of the rate adjustment by the temperature correction data. Become. In addition, by receiving data from the adjustment device via the motor coil 14 of the analog electronic timepiece 10, data can be exchanged without contact between the adjustment device and a circuit block or movement. As a result, the adjusting device does not need to have a high-accuracy probe, and the configuration can be simplified and the cost can be reduced. Also,
Since the analog electronic timepiece 10 is provided with the arithmetic unit 25, the temperature correction data can be calculated only by receiving the start signal and the reference signal from the adjusting device. The temperature correction data of the timepiece 10 can be calculated.

[1.4] Modification of First Embodiment In the above embodiment, when calculating the temperature correction data, the oscillation frequencies f1 to f3 of the temperature-sensitive oscillation unit 16 and the rates y1 to y1 of the analog electronic timepiece 10 are calculated. Although the coefficient β ', the reference frequency ft, and the reference rate y0 are calculated based on y3, the temperature t11 to t13 output from the temperature sensor unit and the analog electronic timepiece 10 are replaced with the temperature sensor unit 16.
Based on the rates y1 to y3, the reference temperature tt,
The reference rate y0 may be calculated. Specifically, unique values (coefficient β ″, reference temperature tt, reference rate y0) of the analog electronic timepiece 10 that satisfy all of the following equations (4) to (6) are calculated, and the coefficient β ″ , The reference temperature tt, and the reference rate y0 as temperature correction data.
0 may be stored in the storage unit 22. y1 = −β ″ (t11−tt) ² + y0 (4) y2 = −β ″ (t12−tt) ² + y0 (5) y3 = −β ″ (t13−tt) ² + y0 … (6)
