Description

  The present invention relates to an analog electronic timepiece that displays a time by rotating a pointer based on updated time data.

  An analog electronic timepiece, like a radio timepiece, recognizes unit time, updates time data based on control by a microcomputer provided in the control unit, and includes a gear and a motor that drives these. The electronic pulse signal is transmitted according to the contents of the time data, and the hands such as the second hand, the minute hand and the hour hand of the display unit connected to the drive unit are mechanically rotated to move the time according to the update of the time data. Some of them are updated on the display.

  In order to display an accurate time on the display unit of such an analog electronic timepiece, it is necessary for a microcomputer that updates time data to accurately recognize the time displayed by the pointer of the display unit.

Here, the control unit provided with the microcomputer is normally operated by receiving power supply from a power source such as a battery constituting the power unit, and the applied voltage value (applied voltage). When the value becomes less than a voltage value (operating voltage value) necessary for operation of the control unit due to power consumption such as battery consumption, the control unit stops operating and the pointer stops rotating hands.
Further, at this time, the time data updated by the microcomputer is reset to the time data when the voltage is first applied to the control unit.
Then, when the pointer stops the rotational movement due to power consumption, a time lag occurs between the time indicated by the pointer on the display unit and the time indicated by the time data. In addition, the power supply can supply a large amount of power by replacing the power supply, etc. Even if the applied voltage value is equal to or higher than the operating voltage value and the control unit resumes operation, the control unit microcomputer no longer shifts the time difference. There is a possibility that the degree of the above cannot be accurately recognized.
In this way, in the above analog electronic timepiece, the applied voltage value is less than the operating voltage value due to power consumption, etc., and the control unit stops operating, and then the applied voltage value exceeds the operating voltage value by replacing the power source. Even if the control unit resumes operation, there is a problem that the microcomputer of the control unit may not be able to accurately recognize the time indicated by the pointer of the display unit.

In Patent Document 1, a detected body such as a light source receiver or a magnetic body is disposed on the gear of the watch body so as to rotate together with the gear around the shaft of the gear, and light is transmitted to a position facing the detected body. There has been proposed an analog radio-controlled timepiece in which a detection body such as a sensor or a magnetic force sensor is provided and the rotational state of the gear is determined by a detection signal from the detection body.
This analog radio-controlled timepiece determines the position of the detected object disposed on the gear from the detection signal of the detected object by the detected object at the time adjustment, and determines the rotational state of the gear and interlocks with the gear. The hand movement position of each hand is determined, and the microcomputer tries to accurately recognize the time displayed by each hand of the display unit.

An embodiment of an analog electronic timepiece according to the invention will be described in detail with reference to the drawings.
FIG. 1 is a schematic configuration diagram showing one example (referred to as a first embodiment) of an analog electronic timepiece according to the invention.
The analog electronic timepiece 1 includes a timepiece main body 2, a control unit 5 connected to the timepiece main body 2, and a power unit 14 that is connected to the control unit 5 and supplies electric power.

  The timepiece main unit 2 includes a display unit 20 provided with a pointer 21 including a second hand 21a, a minute hand 21b, and an hour hand 21c on a clock board 20a, and a driving unit 24 that rotates the pointer 21 in the A direction. Is composed of a first drive unit 24a for moving the second hand 21 and a second drive unit 24b for moving the minute hand 21b and the hour hand 21c. A gear (not shown) is provided.

The power unit 14 includes a power source 7 composed of a battery and an auxiliary power source 9, and includes a detection unit 15 that detects electric power supplied from the power source 7 to the control unit 5.
The power source 7 and the auxiliary power source 9 are not limited to the above-described battery, and a storage battery, a capacitor, or the like can be used in appropriate combination. Moreover, the number of installation of the power source 7 and the auxiliary power source 9 is not particularly limited. The number of power sources 7 and auxiliary power sources 9 to be installed is appropriately determined in consideration of the time during which power can be supplied, the magnitude of voltage necessary for the operation of the control unit 5, and the like.
As the detection unit 15, a detection body that detects the value of the voltage applied to the control unit 5 from the power unit 14 can be employed.

  The control unit 5 includes a quartz oscillation circuit 10, a microcomputer 11 that controls the operation of the analog electronic timepiece 1, various programs for performing arithmetic processing in the microcomputer 11, transmission speeds of electric pulses transmitted to the driving unit 24, and the like. A storage unit 12 including various memories such as a ROM that stores and stores, and a RAM that stores (stores) data processed by the microcomputer 11 is provided.

  In the ROM of the storage unit 12, data corresponding to a predetermined value is stored as a value of power for determining whether or not the rotation hand movement of the pointer 21 of the display unit 20 is stopped, and the RAM of the storage unit 12 is stored. Is provided with a time storage unit, which stores time data sequentially generated by the microcomputer 11 in accordance with a time change. Further, the RAM of the storage unit 12 is provided with a stop time storage unit, which stores stop time data based on the time data stored in the time storage unit when the hand movement of the pointer is stopped.

  In the analog electronic timepiece 1, the microcomputer 11 receives the power supplied from the power source 7 provided in the power unit 14 and updates the time displayed on the display unit 20 in the following manner (pointer rotation). (Hand movement processing) is performed (FIG. 2).

In the analog electronic timepiece 1, the RAM of the storage unit 12 stores time data synchronized with the time displayed on the display unit 20. First, the microcomputer 11 calls the time data (S201).
The microcomputer 11 provided in the control unit 5 obtains a unit time (for example, 1 second) formed by dividing a signal generated by quartz oscillation of a predetermined frequency oscillated from the crystal oscillation circuit, and starts operation of the analog electronic timepiece. Counting is performed every time a unit time elapses with reference to the time, and time data is sequentially created by integrating the number of counts made (S202).
For example, when the analog electronic timepiece starts to operate at 00:00:00, counting is performed every 1 second from that time, and if the integrated value of the number of counts is 59 times, the microcomputer 11 is 00 hours If time data indicating 00 minutes and 59 seconds is created and the integrated value of the count is 62, the microcomputer 11 recognizes that 62 seconds have elapsed from the start of the operation of the analog electronic timepiece, and 00:01 Time data indicating 02 seconds is created.
The microcomputer 11 updates the time data by storing the update time data, which is the sequentially generated time data, in the RAM of the storage unit 12 as the time data.
In the analog electronic timepiece 1, the microcomputer 11 transmits an electric pulse based on the power of the power source 7 to the drive unit 24 to rotate the pointer 21 of the display unit 20 in response to the update of the time data, and display the data. The time displayed on the unit 20 is sequentially updated (S203).

  When the power supplied from the power source 7 to the control unit 5 of the analog electronic timepiece 1 falls below a predetermined value, the analog electronic timepiece 1 stops the rotation hand movement of the pointer as follows (display unit stop) Display process) (FIG. 3).

  The microcomputer 11 determines whether or not the power supplied from the power source 7 to the control unit 5 is equal to or less than a predetermined value (S301). Here, the predetermined value is predetermined as a value (hereinafter referred to as a threshold voltage value) based on a voltage supplied from the power source 7 to the control unit 5, and the magnitude of the threshold voltage value is controlled by the control unit 5. It is appropriately selected from a value equal to or higher than a voltage value (operating voltage value) necessary for operating the unit 5. The storage unit 12 stores data indicating the threshold voltage value in advance.

  The microcomputer 11 receives data indicating the applied voltage value measured by the detection unit 15, and compares the applied voltage value with the threshold voltage value stored in the storage unit 12. Thereby, the microcomputer 11 can determine whether or not the voltage value (applied voltage value) loaded from the power source 7 to the control unit 5 is equal to or less than the threshold voltage value.

When the microcomputer 11 determines that the applied voltage value exceeds the threshold voltage value, the microcomputer 11 continues the rotational movement of the pointer 21 according to the update of the time data.
If the microcomputer 11 determines that the applied voltage value is less than or equal to the threshold voltage value, the microcomputer 11 uses the time data updated and stored in the storage unit 12 as stop time data in the stop time storage unit of the storage unit 12. In addition to storing (S302), the rotation movement of the pointer 21 by the electric pulse based on the electric power of the power source 7 is stopped (S303). Further, at this time, the microcomputer 11 switches the power supply source between the power source 7 and the auxiliary power source 9. In this switching, a signal for causing the auxiliary power source 9 of the power unit 14 to supply power to the control unit 5 (starting) and interrupting (stopping) power supply from the power source 7 to the control unit 5 is sent to the microcomputer 11. Can be implemented by transmitting to the power unit 14 (S304).

.
In the analog electronic timepiece 1, the process after the display unit stop display process (process after display stop) is performed as follows (FIG. 4).
In the analog electronic timepiece 1, even if the supply of power from the power source 7 to the control unit 5 is stopped, power is supplied from the auxiliary power source 9 to the control unit 5 and supplied from the auxiliary power source 9. Based on the power, the control unit 5 performs a process of continuously updating the time data as follows.
The microcomputer 11 provided in the control unit 5 acquires the unit time in the same manner as the unit time is acquired in the time data creation process in the pointer rotation hand movement process, and power supply from the power source 7 to the control unit 5 is performed. Time data is sequentially created by sequentially integrating the number of counts per unit time with respect to the time data stored in the storage unit 12 at the time of stopping. For example, when the unit time is 1 second and the power supply from the power source 7 to the control unit 5 is stopped, the time data is data indicating 8:14:10, and the count value is integrated. Is 70 times, time data indicating 8:15:20, which is 1 minute 10 seconds elapsed from 8:14:10, is created.
The microcomputer 11 sequentially creates time data (continuous update time data) each time the count is performed based on the time data stored in the storage unit, and stores the continuous update time data in the RAM of the storage unit 12 as time data. Thus, the time data is continuously updated (S401).

In addition, after the display unit stop display process is performed, the analog electronic timepiece can again supply electric power larger than a predetermined value from the power source 7 to the control unit 5, that is, from the power source 7. When a voltage larger than the threshold voltage value can be applied to the control unit 5, the time based on the continuously updated time data continuously updated is displayed on the display unit as shown below (automatic time adjustment display processing). .
First, in the analog electronic timepiece 1, it is determined whether or not the electric power supplied from the power source 7 of the power unit 14 to the control unit 5 exceeds a predetermined value. This determination can be performed in the same manner as that performed in the display unit stop display process. That is, the detection unit 15 measures the applied voltage value, and transmits data indicating the voltage value to the microcomputer 11. The microcomputer 11 compares the transmitted data with data indicating the stored threshold voltage value.
When the microcomputer 11 determines that the applied voltage value is greater than the threshold voltage value, that is, when it is determined that the power supplied from the power source 7 of the power unit 14 to the control unit 5 exceeds a predetermined value. (Yes in S402), the power supply source to the control unit 5 is switched from the auxiliary power source 9 to the power source 7 (S403). This switching is performed when the microcomputer 11 causes the power unit 14 to stop supplying power from the auxiliary power source 9 to the control unit 5 and transmits a signal to the power unit 14 to supply power from the power source 7 to the control unit 5. Can be implemented

  While receiving power from the power source 7, the microcomputer 11 calls the stop time data continuously stored in the stop time storage unit of the storage unit 12 and is continuously updated as time data in the RAM of the storage unit 12. The time data is called, and the time difference (Ts1) for the second and the time difference (Tm1) for the hour and the minute are derived between the time corresponding to the stop time data and the time corresponding to the continuous update time data (S404). . Based on the time differences Ts1 and Tm1, the microcomputer 11 counts the number of electric pulses (Ds1) transmitted to the first driving unit 24a to rotate the second hand 21a, and sets the minute hand 21b and the hour hand 21c to rotate. 2 The number (Dm1) of electrical pulses to be transmitted to the drive unit 24b is derived (S405). The microcomputer 11 transmits electrical pulses corresponding to the pulse numbers Ds1 and Dm1 derived for the first drive unit 24a and the second drive unit 24b, respectively, at a predetermined speed (S406). The pointer 21 of the display unit 20 is rotated according to the electric pulse transmitted to the driving unit 24. In this way, the analog electronic timepiece 1 can display the time based on the continuous update time data, which is the time data continuously updated by the time update means and stored in the storage unit 12, on the display unit 20, and automatically. The time can be adjusted automatically.

In the analog electronic timepiece 1, in the automatic time adjustment display process, the microcomputer 11 transmits an electric pulse having a pulse number Dm1 only to the second drive unit 24b to rotate the hour hand 24c and the minute hand 24b, You may comprise so that the rotation hand movement of the second hand 24a may be stopped temporarily.
In this case, in the automatic time adjustment display processing, the microcomputer 11 compares the second value (Se1) designated by the updated time data with the second value (Se2) designated by the stop time data, and the values of Se1 and Se2 are compared. The transmission of the electric pulse to the second hand 24a is stopped until they coincide with each other, and the rotation hand movement of the second hand 24a is stopped. And if the value of Se1 and Se2 corresponds, the microcomputer 11 will rotate the second hand 24a.

  The analog electronic timepiece according to the first embodiment includes reference date data indicating a predetermined date, reference time data indicating a time at which the time is changed, and time to be changed at the time indicated by the reference time data. A change date and time storage unit that stores the corresponding change time data and a date storage unit that stores date data composed of data indicating the year, month, and day, and a date change based on the update of the time data Date update means for updating the date data stored in the date storage unit, and reference date determination for determining whether the date data updated by the date update means corresponds to the reference date data stored in the variable date / time storage unit Means and a reference time determination means for determining whether or not the time data corresponds to the reference time data. The date data corresponds to the reference date data by the boundary date determination means. If the boundary time determination means determines that the time data corresponds to the reference time data, the hand movement means rotates the pointer according to the time indicated by the variable time data corresponding to the reference date data. You may comprise so that it may be made (it is called a 2nd embodiment).

  Similar to the first embodiment, the analog electronic timepiece 1 includes a power unit 14, a control unit 5, and a timepiece main body 2, and each of the power unit 14 and the timepiece main body 2 also includes the first embodiment. It is constituted similarly.

As in the first embodiment, the control unit 5 includes a storage unit 12 having a memory such as a ROM or a RAM, a microcomputer 11, and a crystal oscillation circuit 10.
The ROM of the storage unit 12 is provided with a change date storage unit, and reference date data indicating a predetermined date and reference time data indicating a time at which the time displayed on the display unit 20 is changed. The change time data indicating the time to change with the reference time as a boundary is stored in association with each other. The RAM of the storage unit 12 is provided with a date storage unit, and date data is stored in the date storage unit.

In this analog electronic timepiece 1, the microcomputer 11 synchronizes with the time indicated by the time data that is sequentially produced and updated and stored in the storage unit 12 at 00:00:00 as follows. Update data sequentially.
The microcomputer 11 calls the date data stored in the RAM of the storage unit 12, and synchronizes with the start of 00:00:00, and displays the next day of the date represented by the date data stored in the storage unit 12. The update date data shown is sequentially created, and the date data is updated by storing the update date data in the RAM of the storage unit 12 as date data.
For example, when the date data stored in the storage unit 12 is data indicating February 1, the microcomputer 11 determines that the time data is 00:00:00 from the data indicating the time of 11:59:59 pm When updated to data indicating the time of 00 seconds, the microcomputer 11 creates update date data indicating February 2 in synchronization with the data. The updated date data is stored as date data stored in the RAM of the storage unit 12, whereby the date data is updated from data indicating February 1 to data indicating February 2.

  The analog electronic timepiece 1 performs a pointer rotation hand movement process in the same manner as in the first embodiment.

  The analog electronic timepiece 1 performs the display unit stop display process in the same manner as in the first embodiment, and performs the automatic time adjustment display process when power can be supplied again from the power source 7 to the control unit 5. In this analog electronic timepiece, after the display unit stop display process, the microcomputer 11 continuously updates the date data in synchronization with the continuous update of the time data.

The analog electronic timepiece 1 of the second embodiment performs processing (time variation processing) for varying the time displayed by the pointer 21 of the display unit 20 in accordance with a predetermined date and time (date and time) (FIG. 5).
First, in the analog electronic timepiece 1, the microcomputer 11 determines whether or not the update date data (S501) created in response to the update of the time data corresponds to the reference date data stored in the change date storage unit of the storage unit 12. Processing to determine whether (reference date determination processing) is performed (S502).

The reference date determination process can be performed as follows, for example.
The ROM of the storage unit 12 is provided with a storage area A for storing data (year / month / day data) indicating the date and time of a predetermined period, and stores the date / time data in order. For example, when the predetermined period is from January 1, 2005 to December 31, 2055, the ROM of the storage unit 12 stores data specifying January 1, 2005 in the first address of the storage area A. Store date and date data specifying January 2, 2005 at the second address of the storage area A, and sequentially input date and time data specifying each date until December 31, 2055. Storing. At this time, flag data indicating that it corresponds to the reference date data is attached to the year / month / day data specifying the date indicated by the reference date data.

  The microcomputer 11 synchronizes with the time data being updated to data indicating 00:00:00, and is an address value for designating date data corresponding to the date data stored in the storage unit 12. 1 is added, and date data is acquired from the address indicated by the value obtained by the addition. The microcomputer 11 recognizes whether or not the date data corresponding to the update date data is flag data. If the microcomputer 11 recognizes that the date data is the flag data, the microcomputer 11 determines that the update date data corresponds to the reference date data.

  In the analog electronic timepiece 1, the microcomputer 11 determines whether or not the update time data corresponds to the reference time data stored in the change date and time storage unit provided in the ROM of the storage unit 12 (reference time determination). Process) (S503)

This reference time determination process can be performed as follows, for example, in the same manner as the reference date determination process.
The ROM of the storage unit 12 is provided with a storage area B for storing data (hour / minute data) designating each hour and minute, and stores the hour / minute data in order. For example, the ROM of the storage unit 12 stores the hour / minute data designating 00:00:00 at the first address of the storage area B, and the hour / minute data designating 00: 0st is stored in the second storage area B. Stored in the address, hour / minute data for designating each hour / minute is sequentially stored in each address until 11:59. At this time, flag data indicating that it corresponds to the reference time data is attached to the hour / minute data specifying the time indicated by the reference time data.
Further, the ROM of the storage unit 12 is provided with a storage area C for storing data (second data) designating each second in the same manner as in the case of the hour / minute data, and stores the second data in order. Yes. For example, the ROM of the storage unit 12 stores second data specifying 00 seconds at the first address of the storage area C, stores second data specifying 01 seconds at the second address of the storage area C, and sequentially. Second data for designating each second up to 59 seconds is stored at each address, and flag data indicating that it corresponds to the reference time data is attached to the predetermined second data.

  When the microcomputer 11 updates the time data and creates the updated time data, the microcomputer 11 starts from the address obtained by adding 1 to the address value specifying the hour / minute data and the second data corresponding to the time data stored in the storage unit 12. Get minute and second data. At this time, the microcomputer 11 recognizes whether or not the hour / minute data and the second data corresponding to the update time data are flag data. When the microcomputer 11 recognizes that the hour / minute data and the second data belong to the flag data, the microcomputer 11 determines that the update time data corresponds to the reference time data.

  The microcomputer 11 determines that the update date data corresponds to the reference date data in the reference date determination process (Yes in S502), and determines that the update time data corresponds to the reference time data in the reference time determination process (in S503). Yes), the variable time data stored in the storage unit 12 is called while corresponding to the reference date data, and whether the time is advanced or delayed at the time indicated by the reference time data is identified (S504, S505),

  This identification can be specifically realized, for example, by attaching a positive or negative sign to the value (Ta) of the variation time data stored in the storage unit 12 and the microcomputer 11 recognizing the value of the variation time data. That is, when the microcomputer 11 recognizes that the value of the variable time data is a positive value (Ta> 0), the microcomputer 11 recognizes that the time is advanced from the time indicated by the reference time data, and the variable time data Is recognized as a negative value (Ta <0), it is recognized that the time is advanced from the time indicated by the reference time data.

The microcomputer 11 performs processing (time variation display processing) for rotating the pointer 21 of the display unit as follows.
When the microcomputer 11 recognizes that it corresponds to the case where the time is advanced from the time indicated by the reference time data, the time (Tm2) for rotating the minute hand 21b and the hour hand 21c and the second hand 21a in the time variation display process are rotated. The number of electrical pulses transmitted to the first drive unit 24a to rotate the second hand 21a in association with the time indicated by the fluctuation time data (Tа) as the time (Ts2) to be changed by moving the hand (S506) (S506) Ds2) and the number of electric pulses (Dm2) to be transmitted to the second drive unit 24b to rotate the minute hand 21b and the hour hand 21c (S508).
For example, when the fluctuation time data (Ta) is 1 hour 20 minutes 40 seconds, the time (Ts2) for rotating the second hand 21a is 40 seconds, and Ds2 is the second hand 21a up to the position where the second hand is rotated for 40 seconds. Is the number of electrical pulses required to rotate the needle. Further, the time (Tm2) for rotating the minute hand 21b and the hour hand 21c is 1 hour and 20 minutes, and Dm2 is for rotating the minute hand 21b and the hour hand 21c to the position where the hour hand is rotated for 1 hour and 20 minutes. This is the number of electrical pulses required.

  Then, the microcomputer 11 outputs electrical pulses having pulse numbers Ds2 and Dm2 at a predetermined electrical pulse transmission speed (S509). As a result, the display unit 20 displays the time obtained by advancing the time indicated by the time data by the time indicated by the variable time data.

  When the microcomputer 11 recognizes that it corresponds to the case where the time is delayed with respect to the time indicated by the reference time data, the time (Tm2) for rotating the minute hand 21b and the hour hand 21c and the second hand 21a in the time variation display process are rotated. As the time (Ts2) to be moved by moving the hand, a value obtained by calculating the difference from the rotation cycle time with the magnitude of the time indicated by the fluctuation time data (Ta) is associated (S507). Further, the microcomputer 11 causes the second driving unit 24b to rotate the second hand 21a and the number of electric pulses (Ds2) transmitted to the first driving unit 24a to rotate the second hand 21a and to rotate the minute hand 21b and hour hand 21c. The number (Dm2) of electrical pulses to be transmitted is calculated (S508).

  Note that the rotation cycle time indicates the time required from the time when the pointer 21 of the display unit 20 is arranged at a position for displaying a specific time to the time when the pointer 21 is arranged at the same position. For example, when the hour and minute are arranged at the position of 00:00:00 and then arranged at the same position after 12 hours, the rotation cycle time of the minute hand 21 and the hour hand 21cb is 12 When the time is 00 minutes and the second is placed at the position of 00 seconds and then placed at the same position after 60 seconds, the rotation cycle time of the second hand 21a is 60 seconds. Shall.

  For example, when the rotation cycle time is 12:00 for hours and minutes, 60 seconds for seconds, and the fluctuation time data (Ta) is -1 hour 20 minutes 40 seconds, Tm2 is changed. The time difference indicated by the time data (Ta) is 10 hours and 40 minutes as a time difference from 1 hour and 20 minutes. Furthermore, Ts2 is 20 seconds as a time difference of 40 seconds of 60 seconds. Dm2 is the number of electric pulses required to move the minute hand 21b and the hour hand 21c to the position where the hour hand 21c is turned for 10 hours and 40 minutes, and Ds2 is moved to the position where the second hand 21a is turned for 20 seconds. This is the number of electrical pulses required to make it.

  Then, the microcomputer 11 outputs electric pulses having pulse numbers Ds2 and Dm2 at a predetermined electric pulse output speed (S509). Thereby, the pointer 21 of the display unit 20 is arranged at a position for displaying the time delayed by the time corresponding to the time indicated by the variable time data from the time indicated by the time data.

  In the analog electronic timepiece 1 of the present invention, the microcomputer 11 may be configured to stop updating the date data in synchronization with the update of the time data while performing the time variation display process. With this configuration, it is possible to suppress a possibility that date data is erroneously updated, which occurs when date data is updated in synchronization with update of time data. For example, when the rotation cycle time is 12:00 and the time data is delayed by 1 pm, the microcomputer 11 advances the position of the pointer 21 by 11 hours and places it at a position delayed by 1 hour. Although it is recognized that the position of the hour hand 21 has been advanced, if the update of the date data is kept synchronized with the update of the time data at this time, the date data may be shifted by one day. Therefore, when the update of date data is stopped as described above, the possibility of erroneous update of date data is reduced.

  In the analog electronic timepiece according to the third embodiment, even if the time fluctuates due to the start or end of daylight saving time, the microcomputer automatically recognizes the position of the pointer 21 of the display unit 20 according to the time fluctuating and automatically Changes can be made.

  The analog electronic timepiece 1 of the first embodiment and the second embodiment includes an input unit for inputting time adjustment data from the outside, and a hand operation for operating the hand movement stop unit or the hand movement unit according to the time adjustment data input from the input unit. And adjusting means (referred to as a third embodiment).

  As shown in FIG. 6, the analog electronic timepiece 1 is configured in the same manner as in the first embodiment except that an input unit 30 is provided and connected to the microcomputer 11 of the control unit 5. The input unit 30 includes a switch that forms a transmission state or non-transmission state of a specific signal. In the analog electronic timepiece 1, when the switch of the input unit 30 is in the ON state, the input unit 30 forms an intermittent transmission state of a specific signal to the microcomputer 11, and the switch of the input unit 30 is in the OFF state. In this case, the input unit 30 forms an intermittent non-transmission state of a specific signal to the microcomputer 11. In this case, the time when the intermittent transmission state of the specific signal is formed constitutes the time adjustment data. For example, when a transmission state of a specific signal is intermittently formed for N seconds, it becomes time adjustment data for specifying a time such as (N × E) seconds (E is a positive real number determined in advance).

  In this analog electronic timepiece 1, when the microcomputer 11 receives the time adjustment data input from the input unit 30 by the user, the microcomputer 11 recognizes the time specified by the time adjustment data and corresponds to the recognized time. The number of electric pulses necessary to rotate the pointer 21 is calculated. Then, the microcomputer 11 transmits electric pulses of the number of pulses at a predetermined speed to rotate the pointer 21 displayed on the display unit 20 and to synchronize with the rotational movement of the pointer 21 in the storage unit. The time data stored in 12 is sequentially changed (hand movement adjustment processing).

  If the microcomputer 11 does not receive the time adjustment data, the microcomputer 11 does not perform the hand movement adjustment process and performs the pointer rotation hand movement process.

  In addition, the switch which comprises the input part 30 will be in the ON state with the 1st switch which forms the intermittent transmission state of a specific signal by turning ON, and turns the hour hand 21c and the minute hand 21b. Thus, it may be configured to include a second switch that forms an intermittent transmission state of a specific signal and stops the rotational movement of the second hand 21a.

In this case, the analog electronic timepiece 1 performs hand movement adjustment processing as follows.
When the microcomputer 11 receives the time adjustment data by forming the ON state of the first switch, the microcomputer 11 rotates the hour hand 21c and the minute hand 21b in the same manner as the above-described hand movement adjustment process.
When the microcomputer 11 receives the time adjustment data by forming the second switch ON state, the microcomputer 11 stops the transmission of the electric pulse to the display unit 20 for the time specified in the time adjustment data, and the second hand of the display unit 20 While the rotational movement of 21a is stopped, the change of the time data stored in the memory | storage part 12 is also stopped synchronizing with the rotational movement of the pointer 21.

  This analog electronic timepiece 1 adjusts the time by an external operation while maintaining the time indicated by the time data stored in the storage unit 12 and the time indicated on the display unit by the hand movement adjustment process. can do. Therefore, according to the analog electronic timepiece 1, in order to cause the control unit 5 to recognize the time indicated by the pointer of the display unit, data indicating how much the time indicated on the display unit is changed from the time indicated by the time data. It is not necessary to separately provide a means for storing the information, and the configuration of the control unit 5 can be simplified.

  In the analog electronic timepiece 1 according to the first embodiment, when the power determination unit determines that the value of the power supplied to the power source is equal to or less than a predetermined power value, the hand movement unit rotates the pointer of the display unit. When the hands are moved and the hands are turned until the predetermined time, the hand moving stop means stops the turning hands of the hands, and the power section stops the supply of power from the power source to the control section and is controlled from the auxiliary power source. The first predetermined power value is set to a predetermined value after the pointer is arranged at a position for displaying a predetermined time on the display unit. You may comprise so that it may be more than the value of the electric power required in order to move a pointer until it is arrange | positioned in the position which displays time (it is called 4th embodiment).

The analog electronic timepiece 1 of the fourth embodiment has the same configuration as that of the first embodiment.
In the analog electronic timepiece 1 of the fourth embodiment, the ROM of the storage unit 12 has a predetermined time that is stopped and displayed on the display unit 20 when the power supplied to the control unit 5 of the analog electronic timepiece 1 further decreases. The data corresponding to is stored.

  In the analog electronic timepiece 1 of the fourth embodiment, the pointer turning hand movement process is performed as in the first embodiment.

In the analog electronic timepiece 1, the display unit stop display process is performed as follows (FIG. 7).
In the analog electronic timepiece 1, the microcomputer 11 of the control unit 5 identifies whether or not the electric power supplied from the power source 7 to the control unit 5 is equal to or less than a predetermined value (S701). This identification is performed by determining whether or not the applied voltage value loaded from the power source 7 to the control unit 5 is equal to or lower than the threshold voltage value.
Here, the threshold voltage value is determined by rotating the pointer 21 after the pointer 21 is arranged at a position for displaying a predetermined time on the display unit 20 until the pointer 21 is arranged at a position for displaying the predetermined time again. The voltage is stored in advance in the storage unit 12 as a voltage value that can provide more power than that required to move the hands.
For example, the analog electronic timepiece 1 has a predetermined time of 12:00:00, the second hand 21a of the display unit 20 at that time is 60 seconds, the minute hand 21b is 1 hour, and the hour hand 21c is 360 hours, 12 hours. When configured to move the hands, the pointer 21 of the display unit 20 is disposed at the same position 12 hours later after passing through a predetermined position of 12:00:00. In this case, the threshold voltage value is calculated in advance as a voltage value that can provide power required to rotate the pointer 21 of the display unit 20 for 12 hours or more, and the calculated value is stored in the storage unit 12. Has been.

Next, when the power supplied from the power source 7 of the power unit 14 to the control unit 5 becomes lower than a predetermined value due to, for example, consumption of a battery as the power source 7, that is, the applied voltage value is a threshold voltage. If the value is equal to or less than the value (Yes in S701), the microcomputer 11 calls the time data stored in advance at the time when the applied voltage value is equal to or less than the threshold voltage value and the time data stored when the applied voltage value is equal to or less than the threshold voltage value. A time difference (Ts3) for time and a time difference (Tm3) for hour and minute are derived (S702). Based on the time differences Ts3 and Tm3, the microcomputer 11 counts the number of electrical pulses (Ds3) transmitted to the first drive unit 24a to rotate the second hand 21a and the first hand to rotate the minute hand 21b and the hour hand 21c. The number (Dm3) of electrical pulses to be transmitted to the second drive unit 24b is derived (S703). Based on the derived Ds3 and Dm3, the microcomputer 11 transmits electrical pulses having a number of pulses corresponding to the first driving unit 24a and the second driving unit 24b of the driving unit 24, respectively, at a predetermined speed ( S704).
For example, when the time data is data based on the time of 11:48:10 and the data of the predetermined time is data based on the time of 12:00:00, Tm3 is 12 minutes. Yes, Ts3 is 50 seconds. When the hour hand 21c and the minute hand 21b are pivoted so that one minute corresponds to one electrical pulse, 12 electrical pulses are transmitted to the second drive unit 24b. When the second hand 21a is rotated so that one second corresponds to two electric pulses, 100 electric pulses are transmitted to the first drive unit 24a. Then, the electric pulses having the number of pulses are transmitted to the drive unit 24 at a speed of 10 pulses per second, for example.

Furthermore, the microcomputer 11 performs a process of stopping the rotational hand movement in a state where the hands 21 display a predetermined time.
The microcomputer 11 counts the number of electric pulses transmitted to each drive unit 24a, 24b, and when the number reaches the number (Ds3, Dm3) transmitted to the drive unit 24a, 24b, the electric pulse to the drive unit 24 is transmitted. Supply is stopped (S705). Further, the microcomputer 11 stops power supply from the power source 7 to the control unit 5 and supplies power from the auxiliary power source 9 to the control unit 5 (S706).
Thus, in the analog electronic timepiece 1, the pointer 21 of the display unit 20 is moved to a position corresponding to a predetermined time and stopped.

  The analog electronic timepiece operates in the same manner as in the first embodiment after stopping the hand movement.

  Further, the analog electronic timepiece 1 according to the first embodiment stops storing the stop time data composed of the time data stored in the time storage unit at the time when the hand movement stop unit stops the rotation of the pointer of the display unit. A time storage unit, and when the power determination means determines that the value of the power supplied by the power source exceeds a predetermined power value, the time indicated by the stop time data stored in the stop time storage unit; Depending on the time difference of the predetermined time, the hand moving means may be configured to cause the pointer of the display unit to rotate and display the predetermined time on the pointer (referred to as a fifth embodiment). . When the above-described configuration is provided in the analog electronic timepiece of the first embodiment, the predetermined power value may be equal to or greater than the power value required to operate the control unit.

The analog electronic timepiece 1 of the fifth embodiment has the same configuration as that of the first embodiment.
Furthermore, in the analog electronic timepiece of the fifth embodiment, the storage unit 12 displays a display unit when it is determined that the power supplied to the control unit 5 of the analog electronic timepiece 1 exceeds a predetermined value. Data corresponding to a predetermined time that is stopped and displayed at 20 is stored.

  The analog electronic timepiece 1 of the fifth embodiment performs the pointer rotation hand movement process and the display unit stop display process in the same manner as the first embodiment.

The analog electronic timepiece 1 performs processing after display stop as follows (FIG. 8).
In the analog electronic timepiece 1, as in the first embodiment, even when the supply of power from the power source 7 to the control unit 5 is stopped, the time data is continuously updated (S801).

In the analog electronic timepiece according to the fifth embodiment, after the display unit stop display process is performed, the microcomputer 11 of the control unit 5 has predetermined power supplied from the power source 7 to the control unit 5 as follows. Whether it is less than or equal to the value is identified. This identification is performed by determining whether or not the applied voltage value loaded from the power source 7 to the control unit 5 is equal to or lower than the threshold voltage value. When the power source 7 can again supply electric power larger than a predetermined value to the control unit 5, that is, the power source 7 can load a voltage larger than the threshold voltage value to the control unit 5. Then, the microcomputer 11 determines that the power supplied from the power source 7 of the power unit 14 to the control unit 5 exceeds a predetermined value. However, in the fifth embodiment, the threshold voltage value may be determined in advance as a value equal to or higher than the operating voltage value.
When the microcomputer 11 determines that the power supplied from the power source 7 of the power unit 14 to the control unit 5 exceeds a predetermined value (Yes in S802), the microcomputer 11 performs the same as in the first embodiment. The power supply source to the control unit 5 is switched from the auxiliary power source 9 to the power source 7 (S803).

  While receiving power from the power source 7, the microcomputer 11 calls data specifying a predetermined time stored in the storage unit 12 and is continuously updated as time data in the RAM of the storage unit 12. Time data is called, and a time difference (Ts4) for seconds and a time difference (Tm4) for hours and minutes are calculated between a time corresponding to the continuous update time data and a predetermined time (S804). Based on the time differences Ts4 and Tm4, the microcomputer 11 determines the number of electric pulses (Ds4) to be transmitted to the first driving unit 24a, the minute hand 21b, and the hour hand to rotate the second hand 21a in the same manner as in the first embodiment. The number of electric pulses (Dm4) transmitted to the second driving unit 24b to rotate the needle 21c is derived (S805), and the number of pulses Ds2 derived for the first driving unit 24a and the second driving unit 24b, respectively. Electric pulses corresponding to Dm2 are transmitted at predetermined speeds (S806). The pointer 21 of the display unit 20 is rotated according to the electric pulse transmitted to the driving unit 24.

  The microcomputer 11 calculates the difference between the data indicating the predetermined time and the time data updated and stored in the storage unit 12, and calculates the value of the time difference between the predetermined time and the time indicated by the time data as the time. • Get minutes and seconds. The microcomputer 11 calculates the number of electric pulses necessary for rotating the minute hand 21b and the hour hand 21c and the number of electric pulses necessary for rotating the second hand 21a based on the acquired values. Then, the data is transmitted to each of the drive units 24a and 24b at a predetermined speed, and the time indicated by the time data is displayed on the pointer 21 of the display unit 20. Then, the microcomputer 11 performs a pointer rotation hand movement process as in the first embodiment.

  The analog electronic timepiece according to the third to fifth embodiments includes a data receiving unit that receives data from the outside, and the content of time data stored in the time storage unit according to the content of the received data received from the data receiving unit. May be provided with storage data changing means (referred to as the sixth embodiment).

  In such an analog electronic timepiece 1, the microcomputer 11 changes the time data stored in the storage unit 12 based on the received data received from the data receiving unit 31. For example, when the microcomputer 11 receives the data having the time of 00:00:00 as the received data, the data having the time is stored in the storage unit 12 as the time data.

  The analog electronic timepiece 1 may be configured to change the date data based on the received data received from the data receiving unit 31 by the microcomputer 11. In this case, for example, when the microcomputer 11 receives, as received data, data having the date of January 1, 2005, the data having the date is stored in the storage unit 12 as date data.

In addition, in the analog electronic timepiece 1 of the fourth embodiment and the fifth embodiment, the data transmitting device 32 may be detachably provided on the data receiving unit 31 (FIG. 9).
The data transmission device 32 includes a data transmission unit 33, a data initialization unit 34 provided with an initialization circuit, and a radio wave reception unit 35.
The data transmission unit 33 of the data transmission device 32 is detachably provided to the data reception unit 31 of the analog electronic timepiece 1. For example, the data receiving unit 31 is configured with a data input terminal, and the data transmitting unit 33 is configured with a data output terminal formed in a shape that fits with the data input terminal.

  In the analog electronic timepiece 1 to which the data transmission device 32 is connected, as shown below, the microcomputer 11 receives data specifying the time received by the radio wave receiving means 35, and until the time specified by the data, the pointer 21 Is turned to move the time displayed on the display unit 20 (specified time adjustment processing) (FIG. 10).

  First, in the analog electronic timepiece 1, when the data transmission unit 33 of the data transmission device 32 is connected to the data reception unit 31, the microcomputer 11 transmits the electrical pulse transmitted to the drive unit 24 to be predetermined. A process of rotating the pointer 21 of the display unit 20 to the position indicating the time is performed (S1001). This process is performed as follows, for example.

  The microcomputer 11 calculates the time difference (Tm5, Ts5) between the predetermined time and the time indicated by the time data stored in the storage unit at the time of connection of the data transmission device for the hour / minute and second. For example, when the predetermined time is 12:00:00 (00:00:00) and the time indicated by the time data is 10:20:40, Tm5 is a value of 1 hour 40 minutes. Thus, Ts5 has a value of 40 seconds. The microcomputer 11 counts the number of electric pulses (Ds5, Dm5) to be transmitted to the first drive unit 24a and the second drive unit 24b to rotate the second hand 21a and the minute hand 21b and the hour hand 21c based on the time differences Ts5 and Tm5. And electrical pulses corresponding to the derived pulse numbers Ds5 and Dm5 are transmitted at predetermined speeds, respectively. The pointer 21 of the display unit 20 rotates and moves to a position indicating a predetermined time according to the electric pulse transmitted to the drive unit 24.

  Further, in the analog electronic timepiece 1, when the data transmission unit 33 of the data transmission device 32 is connected to the data reception unit 31, the initialization circuit of the data initialization unit 34 is turned on, so that the contents of the time data Is initialized (S1002). Note that the initialization means forming a time data state in the storage unit 12 when power is first supplied to the control unit 5 of the analog electronic timepiece 1. For example, when power is first supplied to the control unit 5, when the time data in the storage unit 12 is data specifying a predetermined time, the time data is set to a predetermined time by the initialization. It is the data which shows.

Next, in the analog electronic timepiece 1, the microcomputer 11 receives the reception data received by the radio wave reception means 35 via the data transmission unit 33 and the data reception unit 32 (S 1003), and receives data specifying the time from the reception data. recognize. Based on this data and the initialized time data, the microcomputer 11 calculates the time difference between the time indicated by the pointer 21 of the display unit 20 and the time specified by the received data in terms of hours and minutes (Tm6). As with the minute, the second is calculated (Ts6) (S1004).
For example, when the predetermined time is 00:00:00 and the time indicated by the time data becomes a predetermined time by initialization, the time specified by the received data is 01:10:15 In some cases, Tm6 has a value of 1 hour 10 minutes and Ts6 has a value of 15 seconds.

  Then, the microcomputer 11 rotates the number of electric pulses (Ds6) transmitted to the first drive unit 24a to rotate the second hand 21a based on the time differences Ts6 and Tm6, and rotates the minute hand 21b and the hour hand 21c. The number of electric pulses (Dm6) to be transmitted to the second driving unit 24b is derived (S1005), and the electric pulses corresponding to the pulse numbers Ds2 and Dm2 derived for the first driving unit 24a and the second driving unit 24b, respectively. Each is transmitted at a predetermined speed (S1006). The pointer 21 of the display unit 20 is rotated and moved to a position indicating a time designated by received data in accordance with the electric pulse transmitted to the drive unit 24.

  The analog electronic timepiece 1 connected to the data transmission device 32 can receive data specifying a precise time from the outside and adjust the time more precisely.

  The data transmission device 32 includes a switch for starting the operation of the initialization circuit of the data initialization unit 33, and is configured to start the designated time adjustment process when the switch is turned on by the user. May be.

The data transmission device 32 may be connected to the analog electronic timepiece 1 of the third embodiment (referred to as the seventh embodiment).
In the analog electronic timepiece 1 of the seventh embodiment, the designated time adjustment process is performed as follows.
In the analog electronic timepiece 1, the microcomputer 11 rotates the pointer 21 of the display unit 20 until the time designated by the initialized time data using the time adjustment data formed by switching the switch of the input unit 30. Then, the microcomputer 11 initializes the contents of the time data stored in the storage unit 12. The microcomputer 11 performs the same processing as in the sixth embodiment after the initialization of the contents of the time data.

  The analog electronic timepiece according to the first to seventh embodiments may include a standard time adjusting means for adjusting the time between regions having different standard times (referred to as an eighth embodiment). For example, when the standard time is different in region A, region B, region C, and region D, the standard time adjusting means includes a data input unit for specifying regions A, B, C, and D, and a standard time based on location A in advance. A time difference storage unit that stores the time difference is provided. In the analog electronic timepiece 1 of the eighth embodiment, the microcomputer 11 calls the data indicating the time difference of the standard time with respect to the location A from the time storage unit according to the data specifying the area input from the input unit, and the standard time The pointer 21 is rotated according to the time difference.
