(1.2) Operation of Embodiment Next, an inspection process of the analog electronic timepiece 103 will be described with reference to a flowchart of FIG. 5 and timing charts of FIGS. 6 and 7. Here, for the analog electronic timepiece 103, a test mode input signal (a phase modulation signal of data "10010") S for the hand rubbing test with the dial following the timing signal STM from the test control device 105.
The case where the TR is transmitted will be described. Further, in the initial state, it is assumed that the data bit number counter N is 1, and the number of bits of the received data to be read by shifting to the reception mode is X = 5.

In the inspection process, at time t0 shown in FIG. 6, when the crown is operated from the 0th to the 1st position by the operator (step S1), the control circuit 13 changes the operation mode of the analog electronic timepiece 103. The mode is shifted from the normal mode to the reception mode (step S2). That is, the control circuit 13 stops the output of the drive signal by turning on only the p-channel MOS transistor P1 of the drive circuit 16 and turning off the p-channel MOS transistor P2 and the n-channel MOS transistors N1 and N2. At the same time, the sampling drive signal SSP is held at the H level, and the comparator 32 is set to the operating state. As a result, the output terminal O2 of the drive circuit 16 is in a high impedance state and is in an electrically floating state, so that when a magnetic field is applied from the outside, an induced voltage is generated in the motor coil 101. When shifting to the reception mode, the second hand or the like may be shifted for a short period of time in order to notify that the mode has shifted to the reception mode.

Next, the control circuit 13 controls the motor coil 10
Then, it is determined whether or not the timing signal STM has been received via the detection circuit 14 (step S3). If the control circuit 13 has not received the timing signal STM (step S3: NO), the control circuit 13 determines whether or not the elapsed time t 'from the transition to the reception mode by the counter 13A exceeds a predetermined standby time Tc. It is determined whether or not there is (step S13)
If the elapsed time t 'has not exceeded the standby time Tc (step S13: NO), the process returns to step S3, whereas if the elapsed time t' has exceeded the standby time Tc (step S13: YES), the reception mode is terminated and the mode is returned to the normal mode in order to save the power consumption of the comparator 32, or assuming that the mode has been shifted to the reception mode by mistake due to an erroneous operation by the user (step S12). On the other hand, when receiving the timing signal (step S3: YES), the control circuit 13 resets the count value of the counter 13A in synchronization with the timing signal STM at time t1 shown in FIGS. , Counter 13
The counting of A is restarted. As a result, synchronization between the analog electronic timepiece 103 and the inspection control device 105 is established.

Next, when synchronization between the analog electronic timepiece 103 and the inspection control device 105 is established, the control circuit 13
It is determined whether or not a predetermined data detection standby time Ta has elapsed based on the count value of the counter 13A (step S4). When the data detection standby time Ta has elapsed (step S4: YES), the control circuit 13
As shown at time t2 in FIG. 7, the data read timing signal SRD is set to the H level, and the output terminal O2
The voltage level of the reception data DDS is detected through the voltage of
One-bit data is read (step S5).
In this case, since the reception data DDS is at the H level, data "1" is detected.

Next, the control circuit 13 adds 1 to the value of the data bit counter number N. That is, N = N + 1 is set (step S6). This indicates that N-bit data has already been received. Then, the control circuit 13
It is determined whether or not the data bit counter number N is equal to the data bit number X to be read (step S7). If the data bit counter number N is different from the data bit number X (step S7: NO), the previous data reading is performed. It is determined whether or not the elapsed time t "from the read timing (time t2) exceeds a predetermined data detection standby time Tb (step S10). Then, the control circuit 13 determines whether the elapsed time t" has elapsed.
If a predetermined data detection standby time Tb has elapsed (step S10: YES), the reception data is read again as shown at time t3 in FIG. 7 (step S10).
5). In this case, since the reception data DDS is at the L level, data “0” is detected.

In the same manner, the control circuit 13 reads the reception data DDS every data detection standby time Tb, serially / parallel converts the reception data DDS by the data conversion circuit 18, and sequentially stores the data in the data storage circuit 17. Let it. When it is determined that the data bit counter number N is equal to the data bit number X (= 5) (step S7: YES), the control circuit 13 checks the received data (“10010”) DDS received this time. Mode transition signal STR
It is determined whether or not this is the case (step S8). If it is not the inspection mode transition signal STR (step S8: NO), the process returns to the normal mode (step S12), whereas if it is the inspection mode transition signal STR (step S8). : YES), it is determined whether or not the crown is at the position of step 0 (step S9).

When the operator operates the crown at the position of the 0th stage, or when the crown is already at the position of the 0th stage, the control circuit 13 receives the inspection mode transition signal S
The operation mode of the analog electronic timepiece 103 is shifted from the reception mode to the inspection mode in order to perform a hand operation for various inspections according to the type of TR (step S10). In this case, since the control circuit 13 has received the inspection mode input signal STR for inspecting the rubbing of the hands with the dial, when the mode shifts to the inspection mode as shown in FIG. A driving pulse having a frequency four times as high is output, and the driving circuit 16 moves the needle at a speed four times the normal. Thus, the operator can inspect whether the hands do not touch the dial. At this time, the control circuit 1
3 determines whether or not the crown has been operated to the first position (step S11). If the operator has operated the crown to the first position (step S11: YES), the inspection mode ends. To return to the normal mode (step S1
2). When returning to the normal mode, the current time can be displayed again by fast-forwarding the hand to the position where the current time is displayed.

(1.3) Effects of the Embodiment As described above, according to the embodiment, the operator enters the inspection mode by a simple operation of operating the crown to the 0th or 1st stage. Since the transition can be performed, many analog electronic watches can be switched to the inspection mode in a short time, and the work efficiency of the inspection process can be greatly improved. Furthermore, since the operation of the analog electronic timepiece 103 for inspection is switched according to the type of the inspection mode transition signal STR, the inspection content can be handled by merely transmitting a predetermined inspection mode transition signal STR to the plurality of analog electronic watches 103. The same operation can be set, and the work efficiency of the inspection process can be greatly improved. In addition, the analog electronic timepiece 10
No. 3 does not shift to the inspection mode unless the inspection mode shift signal STR is input, so that it is possible to prevent a case where a general user or the like accidentally shifts to the inspection mode by operating the crown or the like.

(2) Modifications (2.1) First Modification In the above-described embodiment, the case of performing a needle rubbing test on a dial has been described. However, as another test inspection example, a wheel train durability test is described. , Test whether or not the auxiliary drive pulse (the drive pulse that is output when the drive motor does not rotate with the normal drive pulse due to dust being caught in the needle etc.) is continuously output, or chargeable analog electronics A charging test (a test in which a high-speed hand movement is performed, the battery voltage is reduced to a certain value or less, and then a charging amount and a charging time by a charging mechanism are inspected) in the watch may be performed.

Furthermore, the present invention is not limited to the above-described inspection requiring hand movement, but also includes a rate measurement inspection (a minute driving pulse is output so as not to move the hand), an internal data inspection performed by transmitting data inside the watch, and a calendar. Correction inspection of date position,
Alternatively, a correction inspection of the position of a hand (such as a chronograph hand) other than the time display may be performed. In the case of this type of inspection that does not require the movement of the needle, it is not necessary to set the crown position to 0 level and connect the needle and the drive motor. It may be made to shift to. In this case, as an operation method for terminating the inspection mode and returning to the normal mode, a method of operating the position of the crown from one step to zero step or one step to zero step to one step, or a method of operating another button Various simple operation methods such as the above may be applied.

(2.2) Second Modification In the above-described embodiment, a case has been described in which the analog electronic timepiece 103 performs the operation of shifting to the inspection mode when the timing signal STM is received once. The present invention is not limited thereto, and the inspection control device 105 transmits the timing signal STM a predetermined number of times (for example, two times), and the analog electronic timepiece 103 transmits the timing signal STM for the number of times.
The transition operation to the inspection mode may be performed only when the TM is received. Thereby, the analog electronic timepiece 10
The analog electronic timepiece 103 can be shifted to the test mode only when the communication state between the third electronic control device 3 and the test control device 105 is good.

(2.3) Third Modification In the above-described embodiment, after shifting to the reception mode, the normal mode is forcibly switched only when the timing signal STM is not received within a predetermined standby time Tc. Although the case of shifting has been described, the present invention is not limited to this, and the mode may be automatically shifted to the normal mode or the receiving mode after a lapse of a certain period after shifting to the receiving mode or the inspection mode.
Further, the reception mode may be provided intermittently during the inspection mode, and when the inspection end signal transmitted from the inspection control device is received during the reception mode, the mode may be shifted to the normal mode or the reception mode.

(2.4) Fourth Modification In the above-described embodiment, the case where the mode is switched to various modes by operating the crown is described. However, the present invention can switch the mode by a simple operation method. The mode may be switched to various modes by operating various controls such as buttons and buttons.

(2.5) Fifth Modification In the above embodiment, the case where the inspection mode transition signal STR is received via the motor coil 101 has been described. The signal may be received via a coil, or may be received by other wireless communication such as infrared communication or wired communication.

(2.6) Sixth Modification In the above-described embodiment, the case where the reception data DDS is detected by using the comparator 32 has been described, but the reception is performed by using an inverter circuit instead of the comparator 32. It is also possible to detect the data DDS. In this case, the circuit configuration can be simplified, and the current consumption of the circuit can be reduced. However, the reference voltage VREF, which is the threshold value for detection, is approximately (high-potential-side power supply Vdd-low-potential-side power supply Vss) / 2, so there is no freedom in setting the detection level.

(2.7) Seventh Modification In the above-described embodiment, the case where the inspection mode transition signal STR is a phase modulation signal has been described. However, the present invention is not limited to this, and amplitude modulation (AM: Amplitude modulation) may be used. modulation
(Including (ASK: Amplitude shift keying))) or a signal subjected to amplitude / phase modulation (AM-PM).

However, the present invention is not limited to this, and a digital timepiece that performs digital display, The present invention can be widely applied to an electronic timepiece such as an analog electronic timepiece with a digital display that includes a sensor for various measurements and digitally displays a measurement result of the sensor.

(2.9) Ninth Modification In the above embodiment, the case where the present invention is applied to an electronic timepiece has been described. However, the present invention is not limited to this, and the operation state is inspected visually by an operator. It can be widely applied to electronic devices that need to be implemented.

[0039]

As described above, according to the present invention, it is not necessary for the operator to perform a complicated operation to shift to the inspection mode as in the prior art, so that many analog electronic watches can be inspected in a short time. The mode can be shifted to the mode, and the work efficiency of the inspection process can be greatly improved. Further, the operation corresponding to the inspection content can be set identically only by transmitting a predetermined inspection mode transition signal to a plurality of analog electronic timepieces, so that the work efficiency of the inspection process can be greatly improved. Furthermore, since the operation is not shifted to the inspection mode only by operating the operation element such as the crown, it is possible to prevent a case where a general user or the like accidentally shifts to the inspection mode.
