BACKGROUND OF THE INVENTION
The present invention relates to a time adjustment system, a time adjustment instruction device, a pointer type timepiece, and a time adjustment method.
[0002]
[Background]
2. Description of the Related Art Conventionally, there is known a pointer type timepiece with a date display that displays a time according to a position of a rotating hand and displays a date by a number on the date wheel by a rotating date wheel. In this date-type pointer-type timepiece, a primary battery such as a silver battery is provided to drive the timepiece itself. For this reason, for example, when the battery runs out and needs to be replaced, bring the watch to the watch store, and the watch store opens the back of the watch and replaces the battery. Was adjusting.
[0003]
In addition, the date-type pointer-type timepiece has a so-called auto-calendar that automatically corrects the date displayed on the date wheel, since one month in the calendar is 30 days or 31 days or a leap year exists. Those with functions have also been developed. In such watches, primary batteries are also used.If the batteries run out, replace the batteries as before, adjust the time and date, and adjust the time and date for setting the auto calendar function. I was adjusting.
Regardless of the presence or absence of these auto-calendar functions, the time, date, and year / month are generally adjusted by operating a crown or a button in such a timepiece.
[0004]
[Problems to be solved by the invention]
However, such adjustment work is troublesome because it must be carried out using a relatively small member such as a crown or a button, and the adjustment work is very complicated. For this reason, when a large number of watches requiring battery replacement are brought in, it takes a considerable amount of time to adjust the date and time associated with battery replacement and delays return to the user.
[0005]
In the watch with an auto calendar function, as described above, when the battery is replaced, the year and month must be adjusted, and the adjustment mechanism and method using the crown and buttons are complicated. For this reason, in order to solve this problem, for example, in Japanese Patent Laid-Open No. 9-61555, a liquid crystal display device or switch dedicated to date correction is provided inside the back cover of the watch, and these liquid crystal display devices and switches are used. A technique for correcting the display date of the date dial of the watch via an internal date correcting circuit or the like by inputting the correct date is disclosed.
However, in this case, since a liquid crystal display device and a switch are separately provided for correcting the date, the number of members such as a liquid crystal panel, a circuit, and a press plate is increased, leading to an increase in the cost and size of the watch. there were.
In addition, even if the counter setting with date information is reset due to some action such as static electricity, and the date is corrected for reasons other than battery replacement, it is necessary to open the back cover and correct the date. There was also a problem that was bad.
[0006]
Further, as shown in Japanese Patent Laid-Open No. 11-190781, in order to provide an auto-calendar function, a drive device for driving the hour / minute / second hand and the date wheel is often provided separately. It is necessary to provide a switch for detecting that the minute / second hand is at midnight, which is disadvantageous in terms of the size of the watch, the number of parts, and the cost of assembly work.
[0007]
Japanese Patent Application Laid-Open No. 10-62567 has a setting unit for setting an auto calendar function in the back cover of a watch, and a calendar and time as calendar information are written in the setting unit with a pencil or the like. What corrects the date and time is disclosed. However, in this case, a space for providing the setting unit is required, which hinders downsizing of the timepiece and can be considered to be small, but in this case, it is difficult to set. Produce. Furthermore, since the setting method is not always simple, there is a need to see a manual or the like, and there is a possibility that the work becomes complicated.
[0008]
On the other hand, there may be a configuration in which a specific button is separately provided on the exterior for correcting the date. Has a problem of deteriorating its appearance.
[0009]

The coincidence circuit 442 outputs a correction signal based on the comparison result to the date indicator driving unit 35, and the date indicator driving unit 35 receiving the signal outputs a fast-forwarding signal for driving the piezoelectric actuator 34 to indicate the date. Fast forward the car 17. At this time, the date feed detection circuit 351 detects the driving of the date dial 17 and outputs the detection result to the day counter 441D, and the day counter 441D to which the detection result is input counts up.
Such a coincidence circuit 442 repeats the above-described operation until the comparison result of both data finally coincides.
In addition, the drive control means 41 and the date indicator drive part 35 are functioning as a correction means. Further, the time correction control circuit 44 and the counter 42 function as comparison means.

[0065]
FIG. 7 is a flowchart showing a procedure for correcting the date and time of the clock in the clock store. First, the watch shop operator removes the back cover of the watch 10 and takes out the primary battery 31 from the inside, and replaces the battery with a new battery (step S1). Simultaneously with the battery replacement, the current time counter 421 and the calendar counter 422 are reset (process S2), and the timepiece 10 starts moving hands every second as usual (process S3).
[0066]
Next, when the operator places the clock 10 on the clock setting table 24 and activates the date / time correction program of the correction instruction device 20 (processing S4), the correction instruction device 20 starts from the clock setting table 24 which is a communication means. A date / time correction start signal is transmitted to the timepiece 10 (step S5). On the other hand, in the timepiece 10, after the date and time correction start signal is received by the external signal detection circuit 43 (processing S <b> 6), the hand movement is divided by 128 Hz or less for counting 1 Hz in the frequency dividing circuit 411. The circuit 411 stops in a reset state. (Processing S7).
[0067]
Next, the correction instruction device 20 displays “Please input the time and date displayed on the clock” on the monitor 23 (step S8). On the other hand, the operator inputs instruction time data which is the display time of the clock 10 and instruction date data (display information) which is the display date from the keyboard 21 (time input procedure).
[0068]
Next, in the correction instruction device 20, the instruction time data and instruction date data of the clock 10 input from the keyboard 21 are transmitted to the clock 10, and the reference date / time data (current year / month) counted by the timer unit 221 is transmitted. Date, hour, minute, second information) is transmitted to the clock 10 (process S9: communication procedure).
[0069]
In the timepiece 10, the instruction time data (hour / minute / second), instruction date data (day), reference date / time data (current date / time, hour / minute / second information) output from the correction instruction device 20 by the external signal detection circuit 43. Is received (process S10: reception procedure). Thereafter, in the timepiece 10, the reference time data (current hour / minute / second) of the reference date / time data is set in the current time counter 421 by the time correction control circuit 44, and the reference date / time data (current year / month) is set. Day) is set in the calendar counter 422 (process S11).
[0070]
Next, in the timepiece 10, the time correction control circuit 44 starts the frequency dividing circuit 411 that counts 1 Hz (seconds), whereby the current time counter 421 starts counting (processing S12).
[0071]
In the timepiece 10, the time correction control circuit 44 sets the instruction time data (hour / minute / second) and instruction date data (day) received from the correction instruction device 20 to the hand position counter 441 (step S13).
[0072]
Next, in the timepiece 10, the coincidence circuit 442 compares the value of the day counter 441D of the hand position counter 441 with the value of the day counter 422A of the calendar counter 422, and based on the correction instruction signal based on the comparison result. The date indicator driving unit 35 outputs a fast-forwarding signal (date-feeding actuator driving pulse) for driving the piezoelectric actuator 34 and fast-forwards the date indicator 17 (processing S14: comparison means, correction means). Based on this feed result, the date feed detection circuit 351 detects the driving of the date wheel 17 and outputs the detection result to the day counter 441D to count up the day counter 441D. Such an operation is repeated until the comparison results of the two data match (processing S15).
[0073]
The coincidence circuit 442 compares the values of the counters 441A to 441C of the hand position counter 441 with the values of the counters 421A to 421C of the current time counter 421, and based on the correction instruction signal based on the comparison result. The frequency dividing circuit 411 switches the pulse output from the pulse generating circuit 412 to a frequency for fast-forwarding, and the pulse generating circuit 412 outputs the switched fast-forwarding pulse (motor fast-forwarding pulse) to the stepping motor 33. (Processing S16: comparison means, correction means). At this time, the stepping motor 33 fast-forwards the pointer 16 in response to the motor fast-forwarding pulse and counts up the second counter 441A of the time correction control circuit 44. Such an operation is repeated until the comparison results of the two data match (processing S17).
[0074]
As described above, the timepiece 10 is corrected for both the time and date, and returns to the normal hand movement state (step S18). In the correction instructing device 20, “correction to the current time is completed” is displayed on the monitor 23 (processing S19), and the time correction program is ended (processing S20). Finally, the operator releases the timepiece 10 from the communication state of the timepiece setting table 24, sets the next timepiece on the timepiece setting table 24, and subsequently corrects the time and date.
[0075]
According to this embodiment, the following effects can be obtained.

Is done. For this reason, the operator can easily correct the time and date without operating the crown or buttons, and can efficiently carry out the work even when there are many correction watches 10.
[0076]
(2) By receiving external data using the motor coil 331 of the stepping motor 33 used for driving the hands 16, it is not necessary to incorporate a receiving member into the timepiece 10 again. The cost can be reduced and the size can be reduced.
[0077]

[0078]
(4) Since the date indicated by the date wheel 17 can be automatically corrected in addition to the time indicated by the hands 16, the correction can be made more efficient than a watch having an auto calendar function. be able to.
[0079]
(5) Since the correction instruction device 20 is configured by a computer, the computer usually has a centennial calendar, so that it can be easily used as a correction instruction device, and a connection circuit with the watch 10 can be easily assembled using an existing interface. It is advantageous in that it is possible to use keyboard input that is familiar to the input of time, etc., and that operations related to correction are displayed on the monitor and the operation is easy.

The control unit 611 includes a needle position counter 441 and a coincidence circuit 442. The needle position counter 441 and the coincidence circuit 442 do not exist in hardware inside the computer main body 61 but are controlled by software so that a memory or the like that is a part of the computer main body 61 is counted and used. It is constructed as a result. Note that the coincidence circuit 442 does not indicate only hardware.
[0084]
The hand position counter 441 stores instruction time data (hour, minute, second) and instruction date data (day) displayed by the clock 50 input from the input unit (keyboard) 21, and stores the stored instruction data. The counter is counted up as an initial value, and includes a second counter 441A, a minute counter 441B, an hour counter 441C, and a day counter 441D.

Based on the correction signal instruction data, the pulse generation circuit 412 outputs a fast-forwarding pulse to the stepping motor 33, and the stepping motor 33 fast-forwards the pointer 16.
[0090]
The time correction control circuit 511 writes the date of the reference date and time among the data received by the external signal detection circuit 43 to the calendar counter 422, and sends a correction instruction signal to the date indicator driving unit 35. The date indicator 17 is fast-forwarded by the piezoelectric actuator 34 based on the correction instruction signal. At this time, the date feed detection circuit 351 detects the driving of the date dial 17. Since the date indicator 17 is set to be fast-forwarded by the date indicator driving unit 35, when the value of the instruction date data is larger than the value of the reference date data, the date written in the calendar counter 422 is Set as the previous month of the specified date / time data. With such a setting, it is not necessary for the operator to determine the previous month input, and workability can be improved.
[0091]
10 and 11 are flowcharts showing the procedure of date correction.
First, the watch store worker removes the back cover of the watch 50, takes out the primary battery from the inside, and replaces the battery with a new battery (step S101). Simultaneously with the battery replacement, the current time counter 421 and the calendar counter 422 are reset (process S102), and the timepiece 50 starts moving hands every second as usual (process S103).
[0092]
Next, when the operator installs the clock 50 on the clock setting table 24 and activates the date / time correction program of the correction instruction device 20 (processing S104), the correction instruction device 20 starts from the clock setting table 24 which is a communication means. A date / time correction start signal is transmitted to the clock 50 (step S105). On the other hand, in the timepiece 50, after the date and time correction start signal is received by the external signal detection circuit 43 (process S106), the hand movement is stopped and the frequency dividing circuit 411 that counts 1 Hz is reset (process S107). .
[0093]
Next, the correction instruction device 60 displays “Please input the time and date displayed on the clock” on the monitor 23 (step S108). On the other hand, the operator inputs instruction time data (hours, minutes and seconds) which is the display time of the clock 50 and instruction date data (display information) which is the display date from the keyboard 21 (time input procedure).
[0094]
Next, in the correction instruction device 60, the indication time data (hour / minute / second) and indication date data (day) of the clock 50 input from the keyboard 21, and the date and time of the reference date / time data counted by the timer unit 221 are displayed.

Thereafter, in the clock 50, the time correction control circuit 511 sets the instruction time data (hour minute second) in the current time counter 421, and the instruction date data (day) and the reference year / month data (year / month) are stored in the calendar counter 422. It is set (processing S112).
[0096]
Next, in the timepiece 50, the time correction control circuit 511 starts the frequency dividing circuit 411 that counts 1 Hz (seconds), and synchronizes the second count-up timing with the correction instruction device 60. Note that the current time counter 421 does not count up (processing S113).
[0097]
In the correction instruction device 60, the coincidence circuit 442 compares the reference date / time data of the timekeeping unit 221 with the instruction date / time data of the hand position counter 441, and the comparison result is obtained via the I / F circuit 223 and the clock setting table 24. A pulse (piezoelectric actuator drive pulse output command) for driving the piezoelectric actuator 34, which is a correction instruction signal based on the above, is transmitted to the external signal detection circuit 43 of the timepiece 50, and at the same time, the day counter 441D is counted up (processing S114: comparison) Procedure, communication procedure). This operation is repeated until the value of the day counter 441D of the hand position counter 441 coincides with the date value of the reference date / time data measured by the timer unit 221 (process S115).
[0098]
In the timepiece 50, the piezoelectric actuator drive pulse output command is received by the motor coil 331 of the stepping motor 33 and the external signal detection circuit 43 (process S116: reception procedure). At this time, the time correction control circuit 511 outputs the received piezoelectric actuator drive pulse output command to the date indicator driving unit 35, and the date indicator driving unit 35 drives the piezoelectric actuator 34 to send the date indicator 17. At the same time, the day counter 422A of the calendar counter 422 is sent for one day (process S117: correction procedure). These operations are performed every time a piezoelectric actuator drive pulse output command is received (step S118).
[0099]
Next, in the correction instruction device 60, the coincidence circuit 442 compares the reference time data of the time measuring unit 221 with the instruction time data of the hand position counter 441, and the I / F circuit 223 and the clock setting table 24 are used. A pulse for driving the stepping motor 33 (motor fast-forward pulse output command), which is a correction instruction signal based on the comparison result, is transmitted to the external signal detection circuit 43 of the timepiece 50 (processing S119: comparison procedure, communication procedure). This operation is repeated until the values of the second counter 441A, minute counter 441B, and hour counter 441C of the hand position counter 441 coincide with the value of the reference time counted by the timer unit 221 (process S120).
[0100]
In the timepiece 50, the motor fast feed pulse output command is received by the motor coil 331 of the stepping motor 33 and the external signal detection circuit 43 (processing S121: reception procedure). At this time, the time correction control circuit 511 outputs the received motor fast-forwarding pulse output command to the pulse generating circuit 412, and the pulse generating circuit 412 drives the stepping motor 33 to fast-forward the pointer 16. At the same time, the second counter 421A of the current time counter 421 is sent for one second (process S122: correction procedure). These operations are performed every time a motor fast-forward pulse output command is received (processing S123).
[0101]
Next, when the transmission of the motor fast-forward pulse output command is completed, the correction instruction device 60 transmits a date / time correction processing end signal to the clock 50 (processing S124). At this time, the clock 50 receives this date / time correction end signal (process S125), and starts counting the current time counter 421 based on the normal hand movement state, that is, the 1 Hz pulse output from the frequency dividing circuit 411. (S126). As described above, in the clock 50, the correction of the time and the calendar ends (processing S127).
On the other hand, in the correction instruction device 60, after the date / time correction processing end signal is transmitted to the clock 50, “correction to the current time is completed” is displayed on the monitor 23 (processing S128), and the time correction program ends. (Processing S129). Finally, the operator releases the timepiece 10 from the communication state of the timepiece setting table 24, sets the next timepiece on the timepiece setting table 24, and subsequently corrects the time and date. Note that the procedure executed by the timepiece 50 or the correction instruction device 60 is configured as a program to be executed by a computer.
[0102]
According to the present embodiment, the following effects can be obtained in addition to substantially the same effects as (1) to (5) of the first embodiment.
(6) Since the hand position counter 441 is provided on the correction instruction device 60 side, the timepiece 50 itself can be manufactured at a low cost without hindering the reduction in size and weight of the timepiece 50.
[0103]
(7) In the pointer-type timepiece 50, data is received by the motor coil 331 of the stepping motor 33, and the correction means is incorporated into the IC portion of the timepiece 50, so that it is not necessary to incorporate new parts and the increase in the number of parts is suppressed. Thus, the watch 50 can be manufactured at a low cost.
[0104]
In addition, this invention is not limited to the said embodiment, Other structures etc. which can achieve the objective of this invention are included, The deformation | transformation etc. which are shown below are also contained in this invention.

Moreover, you may utilize the time information service of the internet which the communication research institute provides information about Japanese standard time information.
Furthermore, although the reference time is obtained by connecting a telephone line, if the operator can directly correct the time of the correction instruction device, it is not necessary to connect the telephone line, and the calendar can be corrected.
[0106]
In each of the above embodiments, a hand-held timepiece having a date display function using a date wheel is adopted, but the present invention is not limited to this. Can be adopted. Note that a date display function that does not depend on the date wheel, for example, a clock having a pointer and a liquid crystal screen is also included in the scope of the present invention. A timepiece having no second hand is also included in the scope of the present invention. Furthermore, as a hand such as an hour hand or a minute hand, a disc-shaped one with a scale can be employed.
[0107]
In each of the above embodiments, a primary battery is used for power supply. For example, a secondary power source (secondary battery) such as a solar charging method, an automatic winding power generation method, an external charging method such as guiding power from a correction instruction device, etc. ) May be adopted. In this case, since there is no need to replace the battery 31, there is an advantage that the work efficiency can be improved without opening the back cover.
[0108]
For the communication between the timepiece and the correction instruction device, electromagnetic induction is adopted. However, the present invention is not limited to this, and other communication means such as optical communication and ultrasonic communication can also be adopted. In the former case, for example, if a solar type is used to secure electric power, a solar cell can be used for this optical sensor, and it is not necessary to provide a new sensor in the watch, so that downsizing and the like are not hindered. In the latter case, there is an advantage that the driving detection terminal of the piezoelectric actuator for driving the date dial can be used as a sensor. Note that sound waves other than ultrasonic waves may be used, and in this case, a timepiece with a buzzer can be configured.
In addition, the computer main body and the watch mounting base are electrically connected. For this connection, for example, an existing USB connection, a SCSI connection, or the like can be employed, and a wireless connection or other connection of infrared communication can be employed.
[0109]
In each of the above embodiments, the data signal is transmitted in one direction from the correction instruction device to the timepiece. However, the present invention is not limited to this. For example, a function for transmitting data from the timepiece to the correction instruction device may be provided. . In this case, it can be transmitted to the correction instructing device that the time adjustment of the clock has been completed, or the value of the current time counter in the clock can be directly read, so that there is an advantage that the time can be corrected more reliably. .
[0110]
In the present invention, the time and date input means is not limited to the keyboard, but may be a camera that recognizes the hour / minute hands and date indicated by the clock. For example, a camera for recognizing the pointer of a clock is provided on the clock mounting base, the clock is picked up by the camera, the time and date indicated by the clock are recognized by image recognition, and this is used as instruction time data for time correction control. By using such means, it is not necessary for the operator to input the designated time, so that the time adjustment work of the clock can be performed more easily, the work efficiency is improved, and the usability as the time adjustment system is improved. .
[0111]
Specifically, for example, as shown in FIG. 13, a camera 70 using a CCD (Charge Coupled Device) is attached to a camera support base 71 so as to be movable up and down. ) The clock 80 installed at 72 is imaged, and image data at the time of imaging is transmitted to a computer main body (not shown) and processed by an image processing program, and the second, minute, hour, and date indicated by the clock 80 are recognized. In this image recognition, the direction of the dial can be determined from the position of the pointer, typesetting, and scale as well as the position of the pointer, typesetting, and scale according to the brightness of the time display section. ) Can also be specified.
[0112]
Further, as shown in FIG. 14, a plurality of installation marks 73 corresponding to the outer shape of the watch may be provided on the watch setting base 72, or a plurality of groove-shaped stepped portions 74 as shown in FIG. As a result, even when a watch having a different size is installed, the direction of the dial is always the same and the center of the dial is at the same position, so that the accuracy of recognizing the hands and the date is improved. In addition, as shown in FIG. 16, a pressing mechanism 75 that can hold the band portion of the timepiece 80 from both sides with the same pressing force may be provided. -It can be installed with the 6 o'clock direction always aligned, which also improves recognition accuracy.
[0113]
When such a camera is used, in order to read the time, it is necessary to know the direction of the dial and the angle of each pointer. In either case, it is necessary to know the center of the dial first, but this can be easily recognized from the image data by finding the intersection of three or two hands (when there is no second hand).
Next, it is the 12 o'clock direction. This is because the timepiece is installed at a substantially fixed position by using the timepiece setting table 72 shown in FIGS. Alternatively, the center of the scale may be determined as the 12 o'clock position. That is, as shown in FIG. 17, even when the actual twelve o'clock position θ0 is deviated from the ideal twelve o'clock position on the watch setting stand, the center of the nearest scale 83 is recognized by image processing. By doing so, the actual 12 o'clock position θ0 can be reliably identified.
Next, the type of the pointer is recognized. In FIG. 17, in the case of the three-needle type, the second hand 85 and the minute hand are arranged in the order from the length L1 to L3 from the center C of the dial 84 (intersection point of the pointer) to the tip of the pointer. 86 and hour hand 87 may be discriminated. As described above, the time can be specified by reading the angle θ1 from the 12 o'clock position θ0 to the second hand 85, the angle θ2 to the minute hand 86, and the angle θ3 to the hour hand 87.

The date can be read by reading the characters at 3 o'clock or 6 o'clock. However, since the date may be displayed at other positions, for example, as shown in FIG. 18, the date wheel 88 on which the date is printed is displayed at a position lower than the dial 84 (further away from the camera 70). By utilizing this, the display position of the date portion can be recognized based on the difference in the focus position when the camera is picked up by changing the focus position.

Furthermore, a watch with a specially designed display may not be recognized by the above recognition algorithm (image processing program). In this case, a recognition algorithm dedicated to the watch may be prepared. The recognition algorithm may be automatically switched by inputting the model name (so-called reference number).
In addition, if an invisible paint such as infrared paint is applied and marked at the 12 o'clock position of the dial, part of the pointer, date display part, etc., the appearance design can be made even for watches with special display parts. The position of each part can be reliably recognized without damaging and without switching the recognition algorithm.

If the hour hand and the minute hand overlap and it is difficult to recognize the short hour hand, it may be determined that the hour hand overlaps the minute hand by being able to recognize only the minute hand. By determining that the angle θ3≈θ2 shown in FIG. 17, the time can be specified without any problem. At this time, there may be some error in the position recognition of the hour hand, but since the hour hand indicates the same time in a large indication range of 5 degrees, there is no problem in accuracy in the actual position recognition. Of course, if it can be recognized that they overlap each other, the position of the hour hand can be accurately obtained from the position of the overlapping minute hands by calculation.
