Japanese Unexamined Patent Publication No. 2016-065825

The pointers such as the hour hand and the minute hand of the analog clock are adjusted so that the current time held internally by the clock and the time actually pointed by the pointer coincide with each other, for example, at the 0 o'clock position as a reference position. However, when an impact is applied to the clock, for example, when the current time coincides with the time corresponding to the reference position (for example, 0 seconds, 0 minutes, etc.), there is a deviation between the position actually pointed by the pointer and the reference position. May occur. If such a deviation occurs, the accurate time cannot be displayed, and the function display for notifying the user of information other than the time (for example, receiving an e-mail) at the position of the pointer cannot be performed. Needs to correct it. In order to improve the convenience of the user, it is desirable that such correction can be easily performed by using a terminal device such as a widely used mobile terminal.

Further, in general, the pointer of the timepiece is driven by a step motor, and the pointer and the step motor are connected by a gear. The angle at which the pointer rotates in one step of the step motor is small, and the gears have backlash (a gap intentionally provided in the direction of rotation between the gears to improve the rotation of the gears). In order to accurately correct the deviation of the pointer from the reference position, it is necessary to take the backlash into consideration. The time correction system of Patent Document 1 corrects the position indicated by the pointer by operating an electronic device, but since the above backlash is not taken into consideration, there is room for improvement in the accuracy of the correction.

Therefore, an object of the present invention is to reduce the burden on the user when correcting the deviation of the pointer of the timepiece with respect to the reference position, and to improve the accuracy of the correction.

It is a system for correcting the deviation of the pointer of the clock from the reference position. The time is displayed by rotating the pointer with the terminal device and the gear, and the gear is rotated according to the instruction from the terminal device to rotate the pointer. The terminal device has a clock for correcting the position, and the terminal device relates to a first instruction unit that outputs a first instruction to rotate the pointer from the position at the start of correction to the reference position to the clock, and a position actually pointed by the pointer. A second instruction that outputs to the clock a second instruction to rotate the pointer according to the amount of deviation between the input unit that accepts the input of the position information and the position indicated by the position information after the rotation according to the first instruction and the reference position. The instruction unit and the third instruction to correct the position of the pointer after rotation by the first or second instruction to the reference position by rotating the gear in a predetermined drive unit according to the input operation of the user, the clock. A system is provided that comprises a third indicator that outputs to.

The third instruction is an instruction to rotate the gear in the forward direction or the reverse direction, and as drive units, the first drive unit when the gear is rotated in the forward direction and the third instruction when the gear is rotated in the opposite direction. Two drive units are set, and it is preferable that the second drive unit is larger than the first drive unit.

As the first drive unit, a plurality of drive units that are smaller than the second drive unit and have different sizes are set, and the input unit can be used as an input operation by any of the plurality of drive units. It is preferable to accept the operation of selecting the rotation of the forward direction or the rotation of the second drive unit in the reverse direction.

When the position of the pointer after rotation by the first or second instruction is advanced with respect to the reference position, the third instruction reverse-rotates the gear to a position lagging behind the reference position in the second drive unit. Then, it is preferable that the instruction is to rotate in the positive direction in the first drive unit.

When the position of the pointer after rotation according to the first instruction is not within the predetermined range, the second instruction unit preferably outputs an instruction to rotate the pointer so as to be included in the predetermined range.

It is preferable that the clock has an hour hand and a minute hand as a pointer, and the third indicator outputs a third instruction when correcting the position of at least one of the hour hand and the minute hand.

The watch has a first pointer and a second pointer as pointers, and the position of the first pointer is corrected according to at least one of the first to third instructions regarding the first pointer. Later, it is preferable to rotate the first pointer to a position other than the reference position and then correct the position of the second pointer according to at least one instruction regarding the second pointer.

The clock has a first pointer and a second pointer as pointers, and the position of the first pointer is corrected according to at least one of the first to third instructions regarding the first pointer. Later, with the first pointer in place at the reference position, it is preferred to correct the position of the second pointer in response to at least one instruction about the second pointer.

The clock has a second hand, a minute hand and an hour hand as pointers, the second hand is thinner than the minute hand and the hour hand, and the clock is the position of the second hand according to at least one of the first to third instructions about the second hand. Then, after correcting the position of the minute hand according to at least one instruction about the minute hand, the minute hand is rotated to a position other than the reference position, and the second hand is placed at the reference position. It is preferable to correct the position of the hour hand according to at least one instruction.

The clock holds the time information indicating the current date and time inside, has an hour hand as a pointer, and further displays the date by rotating the date plate in conjunction with the hour hand with a gear, and the input unit displays the date plate. Further accepting the input of date information regarding the date actually indicated by the terminal device, the terminal device corrects the position of the hour hand according to at least one of the first to third instructions regarding the hour hand. It is preferable that the fourth indicator further includes a fourth indicator for outputting the instruction to the clock, and the fourth instruction is an instruction to rotate the date plate so that the date indicated by the date information matches the date indicated by the time information.

After correcting the position of the hour hand and before outputting the fourth instruction, the fourth indicator rotates the gear in the opposite direction with a drive unit larger than that when correcting the position of the hour hand, and then positively. It is preferable to output an instruction to rotate in the direction to the clock.

The reference position is the midnight position, and the input unit selects whether one date or the part between two adjacent dates is displayed in the date display window of the date plate on the clock. If the user's operation is further accepted and it is selected that the part between the two dates is displayed, the date information is displayed after the clock advances the pointer until one date is displayed in the display window. It is preferable to accept the input of.

According to the above system, the burden on the user when correcting the deviation of the pointer of the timepiece with respect to the reference position is reduced, and the accuracy of the correction is improved.

Hereinafter, a system for correcting the deviation of the pointer of the clock with respect to the reference position will be described with reference to the drawings. However, it should be understood that the present invention is not limited to the drawings or embodiments described below.

FIG. 1 is a schematic block diagram of the adjustment system 1. The adjustment system 1 is an example of a system for correcting a deviation of a timepiece pointer with respect to a reference position, and includes a mobile terminal 2 and a timepiece 3. The adjustment system 1 makes it possible to easily correct the reference position of the pointer (second hand 41, minute hand 42, and hour hand 43) of the clock 3 by operating the mobile terminal 2. In the following, between the position actually pointed by the pointer when instructed to move to the reference position (for example, the 12 o'clock position) and the reference position recognized by the clock 3 (pointer control unit 32 described later). Correcting the deviation is called "adjustment of the reference position".

The mobile terminal 2 is an example of a terminal device, for example, a mobile phone or a smart phone, but the terminal device may be a PC or a tablet terminal, and is not particularly limited. The mobile terminal 2 is used for the user to input an instruction for adjusting the reference position of the pointer of the watch 3, and wirelessly communicates with the watch 3 by, for example, Bluetooth (registered trademark). As shown in FIG. 1, the mobile terminal 2 includes a terminal communication unit 11, a control unit 12, a storage unit 13, a display unit 14, and an input unit 15.

The terminal communication unit 11 is an interface for performing wireless communication with the clock 3. The control unit 12 is composed of a microcomputer including a CPU, a ROM, a RAM, and the like, and controls the operation of the mobile terminal 2. The storage unit 13 is composed of, for example, a semiconductor memory, and stores information necessary for the operation of the mobile terminal 2. The display unit 14 is, for example, a liquid crystal display, but any device may be used as long as it can display an image.

The input unit 15 is, for example, a touch panel or a key button, but may be a keyboard or a mouse. In the case of a touch panel, the input unit 15 may be integrated with the display unit 14 as a touch panel display. The input unit 15 receives input such as position information regarding the position pointed to by the pointer of the clock 3. For example, the user of the adjustment system 1 inputs a numerical value indicating the time actually pointed by the pointer of the clock 3 (currently, what hour, minute, and second) as position information via the input unit 15. do. Note that this position information may be input by the user tapping the position on the dial of the clock displayed on the touch panel display, and may be in any format as long as the position can be uniquely specified. It may be.

The clock 3 is a clock (that is, an analog clock) that displays the time (date and time) by rotating the pointer with a gear, and is a clock communication unit 31, a pointer control unit 32, a clock unit 33, a time display unit 34, and a drive unit. Has 35. The clock 3 is, for example, a wristwatch, but may be a table clock or the like, and is not particularly limited as long as it is an analog clock.

The watch communication unit 31 is an interface for performing wireless communication with the mobile terminal 2. When the pointer control unit 32 adjusts the reference position of the pointer, the pointer control unit 32 rotates the gear in the watch 3 in response to the instruction from the mobile terminal 2 to correct the position of the pointer. The time measuring unit 33 includes, for example, a clock unit that generates a clock signal by a crystal oscillator, a frequency dividing circuit unit that divides the clock signal to generate a frequency dividing signal, and time information indicating the current date and time from the divided signal. It is composed of a known clock circuit having a time generation unit for generating the above.

The time display unit 34 has a second hand 41, a minute hand 42, an hour hand 43, and a day plate 44. Reference numeral 45 is a display window of the date plate 44, and "31st day" is displayed in the example of FIG. By having the date plate 44, the clock 3 displays not only the time but also the date. The clock targeted by the adjustment system 1 is not limited to a clock having three pointers of a second hand, a minute hand, and an hour hand, and may have, for example, a clock having two pointers of a minute hand and an hour hand.

2 (A) to 2 (D) are schematic configuration diagrams of the time display unit 34 and the drive unit 35 of the clock 3. Of these, FIG. 2A is a schematic block diagram showing the relationship between the second hand 41, the minute hand 42, the hour hand 43, and the day plate 44, and the gear 51 and the motors 52, 53 for driving them. Further, FIG. 2B is a schematic configuration diagram of a portion connecting the second hand 41 and the minute hand 42 and the motor 52, and FIG. 2C is a portion connecting the hour hand 43, the day plate 44 and the motor 53. It is a schematic block diagram of.

The drive unit 35 includes a gear 51, motors 52, 53, and drive circuits 55, 56. In the clock 3, the second hand 41 and the minute hand 42 are connected to the motor 52 via a gear (wheel train) 51, and the hour hand 43 and the day plate 44 are connected to the motor 53 via another gear (wheel train) 51. ing. The motor 52 is a step motor for the second hand 41 and the minute hand 42, and the motor 53 is a step motor for the hour hand 43 and the day plate 44. The drive circuit 55 drives the motor 52, and the drive circuit 56 drives the motor 53. In the clock 3, the second hand 41 and the minute hand 42 rotate in conjunction with the common motor 52, and the hour hand 43 and the day plate 44 also rotate in conjunction with the common motor 53. For example, when the second hand 41 is rotated once by the motor 52, the minute hand 42 is advanced by 1 minute (6 degrees), and during that time, the hour hand 43 is rotated once by the motor 53. Since the hour hand 43 advances 30 degrees in 60 minutes, it advances 0.5 degrees in 1 minute. Further, the date plate 44 advances by one day when the hour hand 43 rotates twice.

As shown in FIG. 2D, the drive unit 35 may have three motors 52 to 54, and these motors may independently drive the second hand 41, the minute hand 42, and the hour hand 43, respectively. Alternatively, although not shown, two motors, one for driving the second hand 41 and one for driving the minute hand 42 and the hour hand 43, may be provided to link the rotation of the minute hand 42 and the hour hand 43.

Hereinafter, the reference positions of the second hand 41, the minute hand 42, and the hour hand 43 will be described as being at the 0 o'clock position (12 o'clock position). However, the reference position may be a position other than the 0 o'clock position, for example, the 3 o'clock position. For example, the reference position of the second hand 41 and the minute hand 42 is set to the 0 o'clock position, and the reference position of the hour hand 43 is set to the 3 o'clock position. Etc., it may be different for each guideline.

3A to 3E are diagrams for explaining the effect of backlash on the adjustment of the reference position. FIG. 3A shows a portion of the clock 3 with an hour hand 43 and two gears 51A and 51B for rotating the hour hand 43. 3 (B) and 3 (C) are enlarged views of the portions (connecting portions of gears 51A and 51B) indicated by reference numerals IIIB and IIIC in FIG. 3A. 3 (D) and 3 (E) are enlarged views of the portions (around the tip of the hour hand 43) indicated by reference numerals IIID and IIIE in FIG. 3 (A). FIG. 3 (D) shows the state of the hour hand 43 at the reference position (0 o'clock position) when the gear 51A is rotated in the forward direction (clockwise), and FIG. 3 (E) shows the state of the gear 51A in the reverse direction (counterclockwise). The state at the reference position (0 o'clock position) of the hour hand 43 when rotated to (clockwise) is shown.

FIG. 3B shows the meshing state of the gear 51A and the gear 51B when the hour hand 43 is rotated in the positive direction. Normally, in the clock 3, the gear 51A and the gear 51B mesh with each other so that the hour hand 43 rotates in the positive direction. Therefore, when the reference position is adjusted only by rotating in the positive direction, the watch 3 is not affected by backlash. In addition, as shown in FIG. 3D, the hour hand 43 can be set to the reference position O. On the other hand, FIG. 3C shows the meshing state of the gear 51A and the gear 51 when the hour hand 43 is rotated in the opposite direction. When the meshing state of the gear 51A and the gear 51B is changed from FIG. 3 (B) to FIG. 3 (C) in order to change the rotation direction of the hour hand 43 from the forward direction to the reverse direction, the backlash at the angle α is changed at that time. The amount of feed of the hour hand 43 in the opposite direction is reduced by the minute. Therefore, when the reference position is adjusted only by rotating in the opposite direction, a deviation occurs between the hour hand 43 and the reference position O as shown in FIG. 3 (E), and the adjustment accuracy is lowered.

To remove the effects of backlash, at least one forward rotation is required after the reverse rotation. For example, when moving the second hand from the 5 second position to the 0 second position in the reverse direction, it is necessary to rotate in the reverse direction for 6 seconds and then rotate in the forward direction for 1 second. That is, when rotating in the reverse direction for 1 second, rotation in the reverse direction for 2 seconds and rotation in the forward direction for 1 second are required, and rotation in the reverse direction for 10 seconds is required. In the case of performing the above, rotation in the reverse direction for 11 seconds and rotation in the forward direction for 1 second are required. As described above, the smaller the rotation speed in the reverse direction, the higher the ratio of the operations required to cope with the backlash, resulting in poor energy efficiency.

Therefore, in the adjustment system 1, when adjustment by rotation in the opposite direction is required (that is, when the position actually pointed by the pointer when instructed to move to the reference position is advanced with respect to the reference position). ), In order to eliminate the influence of such backlash, the gear 51 is once largely rotated in the reverse direction, and then the reference position is adjusted while being rotated little by little in the forward direction.

Hereinafter, the functional blocks of the control unit 12 shown in FIG. 1 will be described. The control unit 12 has a movement instruction unit 21, a pointer correction unit 22, a fine adjustment instruction unit 23, an overlap control unit 24, and a date correction unit 25 as functional blocks realized by the operation of the CPU. The reference position of the date plate 44 is adjusted.

In this adjustment process, the control unit 12 first moves the second hand 41 to the reference position by the movement instruction unit 21, and if the position of the second hand 41 after the movement is not the reference position, the pointer correction unit 22 refers to the second hand 41. Instruct the position adjustment. Subsequently, the control unit 12 moves the minute hand 42 to the reference position by the movement instruction unit 21, and if the position of the minute hand 42 after the movement is not the reference position, the pointer correction unit 22 adjusts the reference position of the minute hand 42. Instruct. Subsequently, the control unit 12 moves the hour hand 43 to the reference position by the movement instruction unit 21, and when the position of the hour hand 43 after the movement is not within the predetermined range, the pointer correction unit 22 moves the hour hand 43 to the predetermined position. Move within the range of. If the position of the hour hand 43 after movement by the movement instruction unit 21 or the pointer correction unit 22 is not the reference position, the control unit 12 instructs the fine adjustment instruction unit 23 to adjust the reference position of the hour hand 43. Finally, the control unit 12 instructs the date correction unit 25 to adjust the reference position of the date plate 44.

At the start of the adjustment process, the movement instruction unit 21 acquires information on the current time from the clock 3 via the terminal communication unit 11, and sets this as the adjustment start time. The movement instruction unit 21 is an example of the first instruction unit, and the pointer to be adjusted (for example, the second hand 41 when the second hand 41 is adjusted) is moved from the position corresponding to the adjustment start time to the reference position via the terminal communication unit 11. The instruction (first instruction) to rotate the clock 3 is output (transmitted) to the clock 3. That is, the movement instruction unit 21 drives the motors 52 and 53 so that the value of the time information held by the time measuring unit 33 of the clock 3 becomes the same value as the reference position, and moves the pointer to be adjusted to the reference position. .. For example, if the pointer is heavy and the pointer does not move even if a feed instruction is given by the step motor, or if an impact or the like is applied to the clock 3 and the pointer is misaligned, the movement instruction unit 21 moves the timepiece. The position of the pointer will deviate from the actual 0 second position.

The pointer correction unit 22 is an example of the second instruction unit, and the pointer is provided via the terminal communication unit 11 according to the amount of deviation between the position of the pointer after rotation and the reference position according to the instruction from the movement instruction unit 21. A further rotation instruction (second instruction) is output to the clock 3. This instruction includes information on the amount of deviation between the actual position of the pointer and the reference position, and the actual position of the pointer is given by the position information input by the user via the input unit 15. The pointer correction unit 22 converts the distance between the actual position of the pointer and the reference position into the number of steps of the motor 52 (or 53) required to move the pointer by that distance, and converts it into the number of steps of the motor 52 (or 53), which is the amount of deviation. Output as information. That is, the pointer correction unit 22 calculates the amount of deviation of the current pointer position with respect to the reference position, transmits the information to the clock 3, and adjusts the position of the pointer so that the deviation of the pointer from the reference position is canceled. Is a means for.

As information on the amount of deviation, the pointer correction unit 22 transmits information on the distance (for example, the number of seconds) between the actual position of the pointer and the reference position to the clock 3, and the pointer control unit 32 of the clock 3 transmits the information. The distance may be converted into the number of steps of the motor. However, in that case, since it is necessary to add the function of conversion to the number of steps to the clock 3, as described above, the pointer correction unit 22 converts the distance to the reference position into the number of steps of the motor and the clock 3. It is preferable to send to.

The fine adjustment instruction unit 23 is an example of a third instruction unit, and is an instruction (third) to correct the position of the pointer after rotation according to the instruction from the pointer correction unit 22 to the reference position via the terminal communication unit 11. The instruction and fine adjustment instruction) are output to the clock 3. The instruction output by the fine adjustment instruction unit 23 is an instruction to rotate the gear 51 in the forward or reverse direction (that is, the pointer clockwise or counterclockwise) in a predetermined drive unit according to the input operation of the user. Is. That is, when the fine adjustment instruction unit 23 has a slight deviation between the actual position of the pointer and the reference position even after the adjustment by the instruction from the movement instruction unit 21 or the pointer correction unit 22, the deviation is adjusted. It is a means for finely adjusting the position of the pointer by the user's manual operation so as to cancel it.

This drive unit is the number of steps of the motors 52 and 53, and is the number of steps when the gear 51 is rotated in the opposite direction (the first) rather than the number of steps when the gear 51 is rotated in the forward direction (first drive unit). (2 drive units) is set larger. Further, for rotation in the forward direction, a plurality of drive units having different sizes are set, and all of them are smaller than the number of steps of rotation in the opposite direction. For example, the drive unit for rotation in the forward direction is set to three stages of 1, 3, and 5 steps, and the drive unit for rotation in the reverse direction is set to 20 steps, which is larger than these. The fine adjustment instruction unit 23 causes the display unit 14 to display a screen for allowing the user to select which of these drive units to drive the motor 52 (or 53), and displays the motor in the drive unit selected by the user. The driving instruction is transmitted as a fine adjustment instruction.

As mentioned above, the drive unit in the reverse direction is larger than the drive unit in the forward direction. This is to make fine adjustments to the reference position while rotating in the positive direction. When the position of the pointer advances with respect to the reference position after the rotation instructed by the pointer correction unit 22, the user first selects, for example, one drive of 20 steps in the opposite direction once. Next, while confirming the position of the pointer of the clock 3, the drive in 1, 3 or 5 steps in the forward direction is selected once or a plurality of times. The fine adjustment instruction unit 23 transmits an instruction to drive the motor by the selected number of steps, and the pointer control unit 32 of the clock 3 rotates the gear 51 in the reverse direction and the forward direction in response to the instruction to provide a pointer. To move. That is, the rotation by the fine adjustment instruction unit 23 in a minute number of steps is not performed in the reverse direction, but is performed only in the forward direction.

On the other hand, if the position of the pointer is behind the reference position after the rotation instructed by the pointer correction unit 22, the user moves in the positive direction while checking the position of the pointer of the clock 3. Select drive in 1, 3 or 5 steps once or multiple times. The fine adjustment instruction unit 23 transmits an instruction to drive the motor by the selected number of steps, and the pointer control unit 32 of the clock 3 rotates the gear 51 in the positive direction in response to the instruction to move the pointer. By repeating this process, the position of the pointer can be accurately adjusted to the reference position.

If the position of the pointer after rotation according to the instruction from the movement instruction unit 21 is not within a predetermined range, the pointer correction unit 22 first gives an instruction to rotate the pointer so as to be included in the range. After that, the fine adjustment instruction unit 23 may output the fine adjustment instruction. This predetermined range is a section around the reference position, and may be, for example, a range of 60 degrees from 11:00 to 1:00. In this case, if the pointer is not within the range from 11:00 to 1:00, the fine adjustment instruction unit 23 may output the fine adjustment instruction after rotating the pointer within the range. In this way, by moving the pointer to be adjusted to the periphery of the reference position and then making fine adjustments, the burden on the user can be reduced and the time required for adjustment to the reference position can be shortened.

Further, the second hand 41 and the minute hand 42 may be adjusted only by the instructions from the movement instruction unit 21 and the pointer correction unit 22, and the fine adjustment instruction unit 23 may output the fine adjustment instruction only when the hour hand 43 is adjusted. .. This is because, for example, since the second hand 41 moves 6 degrees in one step, the effect ratio of backlash on the rotation angle for one step is small and the position adjustment is relatively easy, while the hour hand 43 is 30 for one hour. This is because the degree is moved in 60 steps, the rotation angle per step is small, and it is difficult to adjust the position. As for the minute hand 42, when the rotation angle per step is small, the influence ratio of backlash on the rotation angle for one step is large, so that the fine adjustment instruction unit 23 uses the minute hand 42 in addition to the hour hand 43. A fine adjustment instruction may be output at the time of adjustment. Alternatively, in some cases, the fine adjustment instruction unit 23 may output a fine adjustment instruction only when the minute hand 42 is adjusted.

The overlap control unit 24 controls the overlap state of the pointers during the adjustment process. Specifically, the overlap control unit 24 outputs an instruction to rotate the minute hand 42 to a position other than the reference position to the clock 3 after adjusting the reference position of the minute hand 42 via the terminal communication unit 11. As a result, the reference position of the hour hand 43 is adjusted in a state where the minute hand 42 is arranged at a position other than the reference position. Further, the reference positions of the minute hand 42 and the hour hand 43 are adjusted so as to overlap the second hand 41 with the second hand 41 arranged at the reference position. This is because, in general, the second hand 41 is thinner than the minute hand 42 and the hour hand 43, and the minute hand 42 has the same thickness as the hour hand 43. Therefore, if the minute hand 42 is in the reference position, it will be an obstacle when adjusting the hour hand 43. This is because when the second hand 41 is in the reference position, it can be used as a mark when adjusting the minute hand 42 and the hour hand 43.

The date correction unit 25 is an example of a fourth instruction unit, and outputs an instruction (fourth instruction) for adjusting the position of the date plate 44 to the clock 3 via the terminal communication unit 11. This instruction includes information on the amount of deviation between the date actually indicated by the date plate 44 and the date indicated by the time information of the time measuring unit 33, and the date actually indicated by the date plate 44 is used via the input unit 15. Given by the date information entered by the person. In response to an instruction from the date correction unit 25, the pointer control unit 32 of the clock 3 corrects the position of the hour hand 43 so that the date actually indicated by the day plate 44 matches the date indicated by the time information of the clock unit 33. Rotate the date plate 44. Since the day plate 44 rotates in conjunction with the hour hand 43, it is necessary to rotate the hour hand 43 for 24 hours x the number of days in order to align the daily position of the day plate 44 with the reference position, and the amount of rotation becomes enormous. .. Therefore, the date correction unit 25 may not adjust the position of the day on the date plate 44 to the reference position, but simply correct the deviation between the actual date and the date indicated by the time information.

4 and 5 (A) to 5 (K) are diagrams for explaining the flow of the adjustment process by the adjustment system 1. FIG. 6 is a flowchart showing an operation example of the mobile terminal 2. 4A and 4B show screens 101 to 112 displayed on the display unit 14 of the mobile terminal 2 during the adjustment process, and FIGS. 5A to 5K are pointers to the clock 3 in each step of the adjustment process. Indicates the arrangement of. In FIGS. 5A to 5K, the display window 45 (see FIG. 1) of the date plate 44 of the clock 3 is not shown for the sake of simplicity.

First, the control unit 12 of the mobile terminal 2 displays the screen 101 of FIG. 4 that allows the user to select the start of the adjustment process. When the start button 121 on the screen 101 is pressed, the movement instruction unit 21 acquires the current time of the clock 3 and sets this as the adjustment start time (S1). Then, the movement instruction unit 21 transmits an instruction to stop the hands of the clock to the clock 3 (S2).

Next, the movement instruction unit 21 transmits an instruction to move the second hand 41 of the clock 3 to the 0 second position to the clock 3 based on the adjustment start time acquired in S1 (S3). For example, if the adjustment start time is 1:15:40, the clock 3 advances the second hand 41 by 20 seconds. Then, the pointer correction unit 22 displays the screen 102 of FIG. 4 and confirms with the user whether or not the second hand 41 actually points to the 0 second position (S4).

When the second hand 41 of the adjustment start time is at the 40-second position as shown in FIG. 5 (A), the second hand 41 points to the 0-second position (Yes in S4). The process proceeds to S7. When the second hand 41 of the adjustment start time is not at the 40-second position, the second hand 41 does not point to the 0-second position (No in S4). Therefore, when the user presses the NG button 123, the pointer correction unit 22 displays the figure. The screen 103 of 4 is displayed, and the user is made to input the position actually pointed by the second hand 41 (S5). For example, as shown in FIG. 5B, assuming that the second hand 41 is actually in the 59 second position, on the screen 103, the UP button 124 and the DN button 125 allow the user to set the second hand 41 to currently 59 seconds. Enter what you are pointing to. The pointer correction unit 22 transmits an instruction to move the second hand 41 to the 0 second position to the clock 3 based on the input value (position information) (S6). As a result, as shown in FIG. 5C, the position of the second hand 41 is adjusted to the 0 second position.

Subsequently, the movement instruction unit 21 and the pointer correction unit 22 display the screens 104 and 105 similar to the screens 102 and 103 related to the second hand 41 on the minute hand 42, and perform the same processes S7 to S10 as S3 to S6. The minute hand 42 is moved to the 0 minute position. For example, when the movement instruction unit 21 moves the minute hand 42 to the 0 minute position (S7), the minute hand 42 actually points to the 1 minute position as shown in FIG. 5 (D) (in S8). No) and the pointer correction unit 22 let the user input that it is currently pointing to 1 minute (S9). As a result, as shown in FIG. 5 (E), the position of the minute hand 42 is adjusted to the 0 minute position (S10). Then, the overlap control unit 24 transmits an instruction to move the minute hand 42 to the 10-minute position to the clock 3 before starting the adjustment of the hour hand 43 (S11). As a result, as shown in FIG. 5 (F), the minute hand 42 moves to the 10-minute position while the second hand 41 is arranged at the 0-second position.

Subsequently, the movement instruction unit 21 transmits an instruction to move the hour hand 43 to the 0 o'clock position to the clock 3 based on the adjustment start time acquired in S1 (S12). Then, the pointer correction unit 22 displays the screen 106 of FIG. 4 and confirms with the user whether or not the hour hand 43 is between 11:00 and 1:00 (S13).

When the hour hand 43 is between 11:00 and 1 o'clock (Yes in S13), when the user presses the OK button 122, the process proceeds to S16. When the hour hand 43 is not between 11:00 and 1 o'clock (No in S13), when the user presses the NG button 123, the pointer correction unit 22 displays a screen 107 similar to the screen 103 related to the second hand 41, and S5. , S6 and the same processes S14 and S15 are performed. For example, as shown in FIG. 5 (G), assuming that the hour hand 43 is actually between 10 o'clock and 11 o'clock, the pointer correction unit 22 causes the user to input that it is currently pointing to 10 o'clock (S14). ). As a result, the pointer correction unit 22 moves the hour hand 43 to the 0 o'clock position as shown in FIG. 5 (H) (S15).

After that, the fine adjustment instruction unit 23 displays the screen 108 of FIG. 4 and confirms with the user whether or not the hour hand 43 points to the exact position at 0 o'clock (S16). In the case of exactly 0 o'clock (Yes in S16), when the user presses the OK button 122, the process proceeds to S18. If it is not exactly 0 o'clock (No in S16), when the user presses the NG button 123, the fine adjustment instruction unit 23 transmits a fine adjustment instruction to the clock 3 according to the input operation of the user (S17). ..

In S17, the fine adjustment instruction unit 23 displays the screen 109 of FIG. 4 including the buttons 131 to 134 for operating the motor 53 of the clock 3. Button 131 sends an instruction to advance one step in the forward direction, button 132 sends an instruction to advance three steps in the forward direction, button 133 sends an instruction to advance five steps in the forward direction, and button 134 sends an instruction to move back 20 steps in the reverse direction. It is a button to do. While checking the position of the hour hand 43 of the clock 3, the user operates those buttons so that the hour hand 43 is exactly at 0 o'clock, and the fine adjustment instruction unit 23 transmits a fine adjustment instruction according to the operation. Then, the pointer control unit 32 of the clock 3 is made to finely adjust the position of the hour hand 43. As a result, even if the hour hand 43 is actually slightly deviated from the 0 o'clock position (FIG. 5 (I)), the position of the hour hand 43 is adjusted to the 0 o'clock position (FIG. 5 (J)).

After S16 and S17, the date correction unit 25 displays the screen 110 of FIG. 4 and allows the user to select whether the display of the current date plate 44 corresponds to midnight or midnight ( S18). The date plate 44 is interlocked with the hour hand 43 and rotates for one day around midnight. Therefore, at midnight, as shown by reference numeral 141 in FIG. 4, the date number is next. It will be in a half-finished state while switching to the date of. On the other hand, in the case of midnight, as shown by reference numeral 142 in FIG. 4, any one of the numbers is displayed on the display window 45, and the display is not halfway. Therefore, in S18, in order for the date correction unit 25 to determine whether it is midnight or midnight, the date correction unit 25 is adjacent to one date in the display window 45 of the clock 3. Let the user choose which of the parts between the two dates is displayed.

When the halfway display state indicated by reference numeral 141 is selected (Yes in S18), the date correction unit 25 gives an instruction to advance the hour hand 43 by 3 hours to the clock 3 so that the date numbers can be easily read. Transmit (S19). That is, when the date correction unit 25 selects that the portion between the two dates is displayed, the date correction unit 25 sets the hour hand 43 to the 3 o'clock position so that only one date is displayed on the display window 45. Let it proceed (Fig. 5 (K)). On the other hand, when the non-halfway display state indicated by reference numeral 142 is selected (No in S18), S19 is not executed and the process proceeds to S20. Subsequently, the date correction unit 25 displays a screen 111 similar to the screen 103, causes the user to input the currently displayed date, and based on the input value (date information), the date plate 44 actually displays the date. The amount of deviation between the date shown in (S20) and the date indicated by the time information of the time measuring unit 33 is calculated (S20).

After that, the control unit 12 notifies the clock 3 of the current position (hand position) of each pointer (S21), and instructs the clock 3 to return to the normal hand movement operation (S22). When the date input in S20 and the date indicated by the time information of the time measuring unit 33 deviate from each other, the pointer control unit 32 of the clock 3 cancels the deviating time when returning to the normal hand movement operation. The date plate 44 is rotated so as to. Finally, the control unit 12 displays the screen 112 of FIG. 4 indicating that the adjustment process is completed, and ends the series of processes.

As described above, in the adjustment system 1, the adjustment load of the user is reduced and the usability is improved by adjusting each pointer of the clock 3 and the position of the date plate in cooperation with the mobile terminal 2. In particular, by displaying the screen 109 shown in FIG. 4 on the mobile terminal 2 and providing the user with means (buttons 131 to 134) for finely adjusting the position of the pointer, the user can adjust the position of the pointer. Easy to operate. Further, in the adjustment system 1, since the position adjustment is performed in consideration of the backlash of the gear in the timepiece 3, the adjustment accuracy of the reference position is improved. At that time, for example, when it is necessary to reverse one step, it is inefficient to move the hand by moving it back two steps and advancing it by one step. Since the reference position is adjusted while rotating little by little in the direction, it is possible to move the hands efficiently in consideration of backlash.

If the rotation position of the date plate 44 is deviated, the time at which the date display is switched deviates from midnight, so that the user may not be able to correctly select the date display on the screen 110 (S18 in FIG. 6). Therefore, the date correction unit 25 has adjusted the reference position of the hour hand 43 and immediately before the adjustment of the reference position of the date plate 44 so that the date display is switched at exactly midnight (S16 in FIG. 6). A process for removing the backlash deviation of the date plate 44 may be performed between 17 and S18).

In FIG. 2C, the gear that rotates the hour hand 43 and the gear that rotates the sun plate 44 are described as being in direct mesh with each other, but this is a simplified diagram, and in reality, the hour hand 43 is actually engaged. Gears are connected in many stages between the sun plate 44 and the sun plate 44. The gear for rotation of the day plate 44 has a larger reduction ratio and a larger backlash than the gear for rotation of the hour hand 43. It may not be possible to remove the backlash deviation by rotating it to. Therefore, the date correction unit 25, for example, rotates the hour hand 43 in the reverse direction (counterclockwise) by 2 hours and then rotates it in the forward direction (clockwise) by the same 2 hours. It is preferable to output to the clock 3 an instruction to rotate the gear 51 in the reverse direction and the forward direction in a drive unit larger than that when adjusting the position.

The reference position of the hour hand 43 may be the position after the date display on the date plate 44 is switched (for example, the 3 o'clock position). In this case, in S19 of FIG. 6, since the process of advancing the hour hand 43 for 3 hours is not required for adjusting the position of the date plate 44, the operation of adjusting the position of the date plate 44 is simplified.

7 (A) to 7 (D) are diagrams showing a modified example of the pointer arrangement pattern in the timepiece. FIG. 7A is a side view showing the arrangement of the pointer and the movement 36 of the clock 3 described above. In the clock 3, as shown in FIG. 7A, the pointers are arranged in the order of the hour hand 43, the minute hand 42, and the second hand 41 from the bottom (from the side of the movement 36). However, the order of arrangement of the pointers may be reversed, and as shown in FIG. 7B, the pointers may be arranged in the order of the second hand 41, the minute hand 42, and the hour hand 43 from the bottom. Alternatively, as shown in FIG. 7 (C), there is no second hand 41 and the minute hand 42 is arranged on the hour hand 43, or as shown in FIG. 7 (D), there is no second hand 41 and the minute hand 42. The hour hand 43 may be arranged on the top.

In the case of FIGS. 7A and 7C, the overlap control unit 24 may move the minute hand 42 to a position other than the reference position so that the minute hand 42 does not get in the way when adjusting the hour hand 43. good. In the case of FIGS. 7B and 7D, since the hour hand 43 is arranged above the minute hand 42, the minute hand 42 remains in the reference position even when the hour hand 43 is adjusted. The position of the hour hand 43 may be aligned on the top.
