A sounding time signal and the like are known.

In particular, in recent years, radio-controlled timepieces that receive a standard time radio wave and correct the time based on the time code have also become widespread, and an analog radio-controlled timepiece that generates a notification sound at a scheduled time is also known. ing. The analog radio-controlled timepiece includes a time counter that counts time, and a hand driving system that drives a hand in accordance with the time of the time counter.

In the above-mentioned radio-controlled timepiece, it is important to accurately display the time by the hands and to make the time display and the timing of generating the notification sound exactly coincide with each other. At a manufacturing site, there is a demand for a configuration for efficiently inspecting the operation state of a timepiece device in order to ensure product quality.

[0005] In particular, with respect to a pointer driving system for driving the hands, when the assembled and positioned hands are actually driven, the backlash of the gears in the pointer driving system causes a delay between the display of the hands and the time of the time counter. May cause a slight deviation. In this case, the display of the hands and the timing at which the notification sound is generated slightly deviate.

[0006] As an analog alarm clock,
It is common to use a guide mechanism. The guide mechanism is provided with a guide hand for displaying the scheduled time and a guide contact that is switched in conjunction with the driving of the hands, and is configured to generate an alarm sound by switching the guide contact at the same time as the scheduled time. ing. However, since the timing at which the reference contact is switched is affected by a delicate dimensional error between components and the like, there is also a problem that the estimated time displayed by the reference hand is shifted from tens of seconds to several minutes. For a radio-controlled timepiece using a reference mechanism, a configuration that eliminates such a shift in the notification sound due to an error in the reference contact is required.

Accordingly, the present invention has been made in view of such circumstances,
It is an object of the present invention to provide a timepiece device capable of efficiently inspecting its operation state.

FIG. 8 is a flowchart showing the control of the timepiece device 1.

According to this example, the scheduled time at which the alarm is generated is determined by the program stored in the control unit 200 with respect to the time counted by the time counter 500 (that is, the reference time or the hour / minute hand display time). It can be set from 10 seconds to 10 minutes.

The reference contact 807 is connected to the time counter 5
About 5 minutes before the time 00 reaches the scheduled time, the state is switched from OFF to ON. That is, the reference contact 807 is turned off.
The time of switching from to ON is earlier than the scheduled time displayed by the reference hand 808. At the scheduled time, the reference contact 807 is reliably turned ON.

The alarm is generated at a timing based on the time of the time counter 500 after the reference contact 807 is switched from OFF to ON.

That is, as shown in the flowchart of FIG. 8, when the alarm switch 203 is ON (S101), the control unit 200 detects the state of the reference contact 807 (S102). If there is, at the timing when the time of the time counter 500 becomes 10 minutes from 00:00:00 (S103), the notifying means 900
Output an alarm (S104). The alarm is output by the user operating the alarm switch 203 or the snooze switch 204 (S105), or when two minutes have elapsed since the start of the alarm output (S106).
The process ends (S107).

Alternatively, for such control, other configurations are also conceivable, for example, as shown in the flowchart of FIG. According to the flowchart of FIG.
00 indicates that the time of the time counter 500 is 00:00:00
At the timing of an interval of 10 minutes from the second (S201), the states of the alarm switch 203 and the reference contact 807 are detected (S202, S203). If these are ON, the alarm is output to the notifying means 900 (S204). The termination of the alarm is the same as that described above (S205, S206, S207).

According to the configuration of this embodiment, the reference contact 807 is
Even if the timing of switching from FF to ON fluctuates to some extent due to the influence of subtle dimensional errors between components, etc., the timing of generating an alarm can be accurately obtained in seconds.

In this example, the scheduled time can be set at 10 minute intervals. However, if the accuracy of the reference contact 807 is high,
For example, it is also possible to configure so that the scheduled time can be set at shorter time intervals, such as at 5 minute intervals.

Next, the reference contact inspection mode and the scheduled time inspection mode of this example will be described with reference to FIGS.

The control unit 200 of the timepiece device 1 has a reference contact inspection mode for inspecting the reference contact 807 and a scheduled time inspection mode for inspecting the scheduled time. These modes are used for inspecting the operation state of the timepiece device 1 at the manufacturing site.

In the case of this example, the reference contact inspection mode starts after positioning and assembling the second hand, the minute hand, the hour hand, and the reference hand 808, and the scheduled time inspection mode starts after the reference contact inspection mode.

In the reference contact inspection mode, the hour / minute hand drive system 6
20 is fast-forwarded and when the reference contact point 807 is switched, the hand movement form of the hour / minute hand drive system 620 is changed. In the scheduled time inspection mode, the second hand drive system 610 and the hour / minute hand drive system 62
0 is fast-forwarded, the second hand drive system 610 and the hour / minute hand drive system 620 are set to the normal hand movement speed just before the display of the second hand and the hour / minute hand reach the scheduled time, and when the display of the second hand and the hour / minute hand reach the scheduled time, an alarm is issued. appear. The speed at which the second hand drive system 610 or the hour / minute hand drive system 620 is fast-forwarded is set to be faster than the normal hand movement speed when displaying time.

More specifically, as shown in FIG. 10, in the reference contact inspection mode, the alarm switch 203 is turned on (S3
01) and when the reference contact is OFF (S302),
The process is started by a predetermined start command (S303).

The start command of the reference contact inspection mode is issued by a reset switch 201, a time setting switch 202, or the like.
The configuration is such that the input is made in an operation pattern of a plurality of switches. For example, a button-type reset switch 201
And the time setting switch 202 is turned on at the same time, and one of them is turned on while the other is turned off. That is, if a switch for inputting a start command is separately provided, this becomes unnecessary in general use,
Such a configuration is employed.

When a command to start the reference contact point inspection mode is input, the control section 200 rapidly feeds the hour / minute hand drive system 620 (S304). Then, at the same time when the reference contact 807 is turned on (S305), the hour / minute hand drive system 602 is stopped (S306).

In this embodiment, the second hand drive system 610 and the hour / minute hand drive system 602 are controlled by the first stepping motor 6.
11 and the second stepping motor 621. Even if the reference contact 807 is turned on while a pulse is being output to the second stepping motor 621 in the reference contact inspection mode, the pulse is output to the end. Therefore, the situation where the hour and minute hands stop at an odd position is avoided, and the time counter 500
There is no deviation in the hour and minute hands displayed by the timer.

In the standard contact inspection mode, if the standard contact 807 operates normally, the time displayed by the hour and minute hands is about 5 minutes before the time displayed by the standard hand 808.
After confirming this, the scheduled time inspection mode is started next.

As shown in FIG. 11, the scheduled time inspection mode is started by a predetermined start command when the alarm switch 203 is ON (S401) and the reference contact is ON (S402) (S403).

The start command of the scheduled time inspection mode is configured to be input in an operation pattern of a plurality of switches, similarly to the start command of the reference contact inspection mode.

When a command to start the scheduled time inspection mode is input, the control unit 200 rapidly feeds the second hand drive system 610 and the hour / minute hand drive system 620 (S404). Thereafter, the second hand drive system 610 and the hour / minute hand drive system 620 are tuned (S40).
5) When the display of the second hand and the hour / minute hand is 5 seconds before the scheduled time (S406), the second hand drive system 610 and the hour / minute hand drive system 620 are set to the normal hand movement speed (S407).

In the scheduled time inspection mode, the timing at which the second hand drive system 610 and the hour / minute hand drive system 620 are set to the normal hand movement speed is preferably 3 to 15 seconds before the scheduled time in consideration of the efficiency of the inspection. Then it is 5 seconds before.

The synchronization of the second hand drive system 610 and the hour / minute hand drive system 620 means that the second hand display time matches the second unit of the hour / minute hand display time. In the case of this example, one of the second hand and the hour / minute hand that has reached 5 seconds before the scheduled time is temporarily stopped, and the other hand waits for the other hand to reach 5 seconds before.

At the same time when the display of the second hand and the hour / minute hand reaches the scheduled time (S408), an alarm is output and the second hand drive system 610 and the hour / minute hand drive system 602 are stopped (S4).
09).

Here, before the display of the second hand and the hour / minute hand reaches the scheduled time, the movement of the second hand and the hour / minute hand and the occurrence of an alarm are observed to confirm their coincidence. If there is no difference between the time displayed by the second hand and the hour / minute hand and the time of the time counter 500, the movement of the second hand and the hour / minute hand coincides with the occurrence of the alarm.
