Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multifunctional timekeeping device having a hand.

[0002]

2. Description of the Related Art Conventionally, as a multifunctional timekeeping device having a hand, there is, for example, a timepiece having an analog display type chronograph function.

Such a timepiece has, for example, an hour chronograph hand, a minute chronograph hand and a second chronograph hand for a chronograph, and has a start / stop provided on the timepiece.
When the stop button is pressed, time measurement starts, and the hour chronograph hand, minute chronograph hand, and second chronograph hand rotate. Then, by pressing the start / stop button again, the time measurement is ended, the hour chronograph hand, the minute chronograph hand and the second chronograph hand are stopped and the measured time is displayed. Then, when the reset button provided on the electronic timepiece is pressed, the measurement time is reset, and the hour chronograph hand, the minute chronograph hand and the second chronograph hand return to the zero position (hereinafter referred to as zero return).

As a method of resetting, when the timepiece is an electronic type, each hand is returned to zero by being fast forwarded by a chronograph motor, and when the timepiece is a mechanical type, each hand is mechanically moved. Zeroed. Some of the mechanical zeroing mechanisms are provided with a safety mechanism for preventing the resetting button from being reset to zero by mistake during the time measurement. This safety mechanism is a mechanism that disables resetting of the time measurement after starting the time measurement and resets the time measurement after stopping the time measurement.

In addition, the timepiece has a function of automatically stopping the hour chronograph hand, the minute chronograph hand and the second chronograph hand at the start hand position of time measurement when the maximum measurement time is reached. With this function, start / measure during time measurement
Even if you forget to press the stop button, it is possible to prevent unnecessary power consumption.

[0006]

The safety mechanism described above is
Each time the start / stop button is operated, the zero-reset impossible state and the zero-reset possible state are mechanically alternately repeated. Conventionally, such a safety mechanism is provided in a mechanical timepiece. Therefore, there was no particular problem. However, when the electronic timepiece is equipped with a mechanical zero-reset mechanism and a safety mechanism, the control circuit of the timepiece recognizes a non-zero-reset state and a zero-resettable state, and a safety mechanism has a non-zero-reset state and a zero-resettable state. Recognition may be reversed.

For example, as shown in FIG. 22, when the start / stop button is pressed and the start signal is output at time T1, the measurement recognition (motor pulse output) of the control circuit is turned on and the safety mechanism is activated. It becomes impossible to zero. After that, when the power supply voltage becomes lower than the operating voltage required for the operation of the control circuit at time T2 due to discharge or the like, the measurement recognition (motor pulse output) of the control circuit is turned off, but the safety mechanism is The non-zeroing state will be maintained.
Then, these states are maintained even after the power supply voltage is restored to the operating voltage or higher due to charging or the like at time T3.

Therefore, when the start / stop button is pressed and the start signal is output at the subsequent time point T4,
The measurement recognition (motor pulse output) of the control circuit is turned on, but the safety mechanism is set to the zero-returnable state. Further, when the start / stop button is pressed and a stop signal is output at time T5 thereafter, the measurement recognition (motor pulse output) of the control circuit is turned off.
The safety mechanism will be in a non-zeroing state.

For this reason, if the reset button is erroneously pressed and a reset signal is output between time points T4 and T5,
Since the safety mechanism is in the zero-reset enabled state, it is reset to zero during time measurement, and even if the reset button is pressed and the reset signal is output at time T6, the reset recognition of the control circuit is turned on. However, since the safety mechanism is in a state where zero reset is not possible, zero reset is not possible even when the time measurement is stopped. As described above, when the chronograph function abnormally stops, the start / stop and reset operations of the chronograph have a problem that the recognition of the control circuit and the state of the safety mechanism are reversed.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and provide a timekeeping device which can always match an electrical operating state and a mechanical operating state.

It is possible to prevent such a malfunction.

[0023]

A detailed configuration example and an operation example of the switch A input circuit 1823, which is a main part of the present invention, will be described with reference to FIGS. 18 to 21.

The switch A input circuit 1823 includes a sampling pulse generation circuit (first circuit) 1901, a switch state holding circuit (second circuit) 1902, and a NAND circuit (third circuit) 1903.

The sampling pulse generation circuit 1901
Signals (first and second pulse signals) SHD of different frequencies divided by the high-frequency divider circuit 1802, for example, FIG.
By inputting the divided pulse signals of φ × 2 kM and φ128 as shown in (4), the pulse signal of φ × 2 kM becomes L level (first level) at the falling timing of the pulse signal of φ128. H at the falling edge of
A signal A (third pulse signal) as a sampling pulse which becomes the level (second level) is output. Here, φ represents Hz, × represents inversion, and M represents shift of half wavelength.

The switch state holding circuit 1902 receives the signal A from the sampling pulse generating circuit 1901 and the switch signal (starting signal) SS from the switch A (first starting means) 1821. The switch signal SS is pulled down while the signal A is L, and becomes H level when the switch A1821 is on and becomes L level when the switch A1821 is off. Therefore, the switch state holding circuit 1902 samples the switch signal SS by the signal A, as shown in FIG.
When S is H level, H at the rising timing of signal A
When the switch signal SS is at the L level and the switch signal SS is at the L level, the signal B (fourth pulse signal) that holds the switch state such that the signal A becomes the L level at the rising timing is output.

As shown in FIG. 20, the NAND circuit 1903 receives the signal B from the switch state holding circuit 1902, and φ128 from the high frequency divider circuit 1802.
By inputting the pulse signal of, when the signal B is at the L level, it becomes the H level, and when the signal B is at the H level,
A signal C (fifth pulse signal) is output as a start signal SST / stop signal SSP that becomes L level at the rising timing of the φ128 pulse signal and becomes H level at the falling timing of the φ128 pulse signal. Input to the mode control circuit 1824.

In such a configuration, as shown in FIG. 21, for example, the start / stop button 12 is activated at time T1.
When 01 is pressed and the switch A1821 is turned on, the switch state holding circuit 1902 is switched from the switch A1821.
Then, the switch signal SS which has become the H level is input.
Then, the switch state holding circuit 1902 outputs to the NAND circuit 1903 a signal B which is at the H level at the rising timing of the signal A from the sampling pulse generation circuit 1901. Then, the NAND circuit 1903 outputs to the mode control circuit 1824 a signal C which becomes L level at the rising timing of the φ128 pulse signal and becomes H level at the falling timing of the φ128 pulse signal. Therefore, the measurement recognition (motor pulse output) of the mode control circuit 1824 is turned on, and the safety mechanism is set to the zero-zero-disabled state.

After that, at time T2, for example, the power generator 160
When the power generation state of 0 causes the voltage of the secondary power source 1500 to drop, the power source voltage of the large-capacity capacitor 1814 becomes equal to or lower than the operating voltage of the control circuit 1800.
The secondary power source 150 is charged by the power generator 1600 in step 3.
When the power supply voltage of 0 is restored to the operating voltage or higher, the mode control circuit 1824 again samples the switch state of the start / stop button 1201 to determine the measurement / non-measurement state, that is, the resettable / not resettable state. To do. At this time, the measurement recognition (motor pulse output) is maintained in the ON state, and the safety mechanism is also maintained in the non-returnable state.

Therefore, when the start / stop button 1201 is pressed and the switch A1821 is turned off at the subsequent time T4, the switch A1821 sends the switch state holding circuit 1902 a switch signal SS at the L level.
Is entered. Then, the switch state holding circuit 1902
From the sampling pulse generating circuit 1901 to the NAND circuit 1903, the signal B that is at the L level is output at the rising timing of the signal A. Then, the NAND circuit 1903 outputs the signal C at the H level to the mode control circuit 1824.

Therefore, the measurement recognition (motor pulse output) of the mode control circuit 1824 is turned off, and the safety mechanism is set to the zero return enabled state. Further, when the reset button is pressed and a reset signal is output at time T5 thereafter, the reset recognition of the mode control circuit 1824 is turned on,
It will be zeroed.

In this way, even when the chronograph function is abnormally stopped, the start / stop and reset operations of the chronograph can always make the recognition of the control circuit and the state of the safety mechanism coincident with each other. It is possible to prevent that the value is zeroed in or that the value cannot be zeroed even though the normal time measurement is stopped. The present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the claims.

For example, in the above-described embodiment, the secondary power source 1500 stored by the power generator 1600 is used as the power source of the electronic timepiece 1000, but the present invention is not limited to this, and a conventional power source battery such as a button battery. May be Furthermore, in addition to the power generation device 1600 or instead of the power generation device 1600, a solar cell or a rechargeable battery may be used.

Although the power generator 1600 for generating power by the rotary weight 1605 is used, a power generator for generating power by rotating the generator by using the torque for unwinding the mainspring wound by the external operating member such as the crown may be used. Good.

Further, the number of the motor 1400 of the chronograph section 1200 is one, but the invention is not limited to this, and each needle of the chronograph section 1200 may be provided with a motor.

Although the electronic timepiece having the analog display type chronograph function has been described as the timing device, the timepiece device is not particularly limited to this, and any analog display type multifunctional timepiece may be used, for example, a portable timepiece. ,Watches,
It can be applied to table clocks, wall clocks, etc.

[0135]

According to the present invention, after the elapsed time measurement is started, the elapsed time measurement cannot be reset until the elapsed time measurement is stopped, and the elapsed time measurement is performed. After starting, until the operation of the elapsed time is stopped normally, it has an electrical function to continue the electrical ON state of the elapsed time measurement. The non-resettable state of the dynamic function always matches. Then, when the operation of measuring the elapsed time is stopped by the drop of the power supply voltage and becomes a voltage at which the operation can be performed again, the electrical ON state described above is continuously maintained and the mechanical reset operation described above is disabled. The state is maintained. As a result, it is possible to prevent such a problem that the time is zeroed during the time measurement, or the time cannot be zeroed even when the time measurement is stopped.
