Description

  The present invention relates to an electronic timepiece that corrects display information by operating an operation member.

  2. Description of the Related Art Conventionally, an electronic timepiece that corrects display information using an electronic crown is known (see, for example, Patent Document 1).

The electronic timepiece disclosed in Patent Document 1 displays display information such as time on display means such as hands on a dial, and correction of the display information can be performed by an electronic crown.
In the electronic timepiece of Patent Document 1, when the display information is corrected by the electronic crown, the measurement condition of the rotation signal when the crown is rotated is changed according to the pull-out position of the crown in the axial direction. Based on this, the correction amount of the information to be corrected is varied.
By varying the amount of correction in this manner, the disadvantage of the crown that the operability differs depending on the operation position of the crown is compensated, and the correction operation by the crown is facilitated.

JP 2008-134129 A

  However, when it is necessary to switch the information to be corrected not by the position of the crown in the axial direction but by a button operation, the electronic timepiece of Patent Document 1 described above measures the rotation signal when the crown is rotated. There is a problem that the conditions and the amount of correction cannot be changed, and detailed correction according to the user's intention cannot be made.

For example, an electronic timepiece with three chronograph hands, a 1/5 second chronograph hand, a minute chronograph hand, and an hour chronograph hand, and a chronograph function capable of measuring up to 6 hours There is a case where the mode is shifted to a mode for correcting the reference position (0 position) of the chronograph hand by pulling out two stages, and the correction target is selected from the three types of chronograph hands by button operation.
In the electronic timepiece of Patent Document 1, assuming that the reference position of such a chronograph hand is corrected, the pull-out position of the crown is not changed. Therefore, even if the correction target is changed by a button operation, the measurement condition of the rotation signal The amount of correction cannot be changed. For this reason, when the normal correction mode (single correction mode) in which the pointer is moved step by step and the continuous correction mode in which the pointer is continuously moved in a plurality of steps can be selected, the correction amount of the continuous correction mode is also determined by the pulling position of the crown. If they are the same, the correction amount is the same.

For this reason, if a setting suitable for correction of one of the chronograph hands is performed, there is a problem that correction of other chronograph hands becomes inconvenient.
For example, when the reference position (0 position) of the 1/5 second chronograph hand is corrected with the crown, the total number of correction amounts of the 1/5 second chronograph hand is as large as 300 (0 to 299). Therefore, when the crown is pulled out to the second position, the correction amount in the normal correction mode is “1”, and the correction amount in the continuous correction mode is “300”. Easy to operate.
However, with the hour chronograph hand, the total number of corrections is as small as 6 (0 to 5), so an operation of correcting the hands one step at a time is sufficient, and an operation of continuously correcting is difficult to match the intended scale. That is, when the continuous correction amount is 300 and if the mode is unintentionally shifted to the continuous correction mode, a correction amount that is 50 times the total correction amount (6) is input, and the hour chronograph hand is moved a plurality of times. Rotating, there is a problem that it becomes difficult to adjust the hour chronograph hand to the reference position.
Such a problem is not limited to the pointer, and is a problem common to a case where display means such as a calendar car is corrected by a rotation operation of an operation member such as a crown.

  An object of the present invention is to provide an electronic timepiece capable of improving the operability when correcting the display means by rotating the operation member.

  The electronic timepiece of the invention includes a display unit that displays display information, a drive mechanism that drives the display unit, an operation member that can be rotated, and the display unit that is displayed by the rotation operation of the operation member. Control means for correcting display information, and the control means has a single correction mode and a continuous correction mode selected by a rotating operation of the operation member, and the single correction mode is simply connected to the drive mechanism. A correction signal is output to correct the display means with a single correction amount. In the continuous correction mode, a continuous correction signal is output to the drive mechanism to correct the display means with a continuous correction amount. Is set according to the type of the display information corrected in the continuous correction mode.

In the present invention, the display information includes, for example, current time information, date and day of the week, chronograph timing information, current position acquired by receiving satellite signals, a time zone selected based on the current position, The time (home time) of a different time zone is exemplified. Examples of the display means include a pointer, a display car such as a calendar car, and the like. A crown can be used as the operation member.
In the present invention, display information is displayed by the display means. The display information on the display means can be corrected by rotating the operation member. At this time, the control means selects the single correction mode or the continuous correction mode by rotating the operation member.
In the single correction mode, the control means outputs a single correction signal to the drive mechanism each time a rotation operation of the operation member is detected, and corrects the display means such as the pointer with a single correction amount. For this reason, the display means such as the pointer can correct the display information to be corrected for each scale, and can perform fine settings.

  In the continuous correction mode, a continuous correction signal is output to the drive mechanism to correct display means such as a pointer with a continuous correction amount. This continuous correction amount is set according to display information to be corrected. While the continuous correction signal is output, the display unit is continuously corrected without operating the operation member. Therefore, the display unit can be fast-forwarded and a quick correction operation can be performed. it can. In addition, by performing rotation operation with the operation member during continuous correction, it is configured so that continuous correction can be stopped, so that continuous correction stops near the correction position intended by the user during continuous correction, and single correction mode Since it is possible to move to the correction position, it is possible to save the correction operation rather than repeating the single correction operation.

In the present invention, the number of continuous correction amounts in the continuous correction mode is set by the control means in accordance with the type of display information. Thereby, since the continuous correction amount can be made variable according to the type of information, fine correction can be made according to the total number of correction amounts of the display information.
For example, when the total correction amount of the display information is as small as 2 to 60, or when the correction time for the total correction amount is as short as 4 seconds or less, when the continuous correction operation is performed, until the correction of the display means is completed Since the time is short, it often passes the correction position intended by the user.
On the other hand, when the total correction amount of the display information is as large as 60 to 720, or when the correction time for the total correction amount is long as 5 seconds or more, continuous correction suitable for information with a small total correction amount If the correction is performed by the amount, the correction amount may not be sufficient for one continuous correction operation, and a plurality of continuous correction operations must be performed.
Thus, in any case, it is necessary to repeat the correction operation with the operation member, and the correction operability is lowered.

  On the other hand, in the present invention, since the continuous correction amount is set according to the type of display information corrected in the continuous correction mode, for example, the continuous correction amount that matches the total number of correction amounts for each display information is set. Can be set. Therefore, even in the continuous correction mode, it is easy to correct the scale intended by the user, and the operability when correcting the display means can be improved.

In the electronic timepiece according to the aspect of the invention, when the operation member rotates a predetermined angle, a rotation operation is detected. When the rotation operation is detected once within a predetermined time, the control unit selects the single correction mode, It is preferable to select the continuous correction mode when a rotation operation in the same direction is detected a plurality of times in a time.
In the present invention, the user can select the single correction mode or the continuous correction mode only by changing the rotation operation amount of the operation member within a predetermined time. Therefore, the operability at the time of correcting the display means can be improved as compared with the case where each mode is selected by button operation or the like.

In the electronic timepiece according to the aspect of the invention, it is preferable that the control unit sets the continuous correction amount to the same correction amount as the total correction amount of the display information corrected in the continuous correction mode.
Here, the total number of correction amounts of the display information is the correction amount until the display means such as the pointer returns to the original position where the correction is started, that is, until the same information is displayed. For example, in the case of a pointer indicating the same second when rotating once (360 degrees) like a second hand, the total number of correction amounts means a correction amount necessary to rotate the pointer once.

  In the present invention, since the continuous correction amount is the same correction amount as the total correction amount of the display information, even if the user who tried to perform the correction operation in the single correction mode erroneously performs the continuous correction operation, the display means Goes around and returns to its original position. Therefore, even if the continuous correction operation is mistakenly performed, there is no significant deviation from the correction position intended by the user. Therefore, the correction operation in the single correction mode is continuously performed, so that the correction position intended by the user can be easily corrected.

In the electronic timepiece according to the aspect of the invention, when the driving mechanism is capable of only correcting the forward direction or the backward direction of the display unit, the control unit sets the continuous correction amount as the single correction amount. The same correction amount is preferable.
Some display means change only in one direction. For example, when a thick hand is attached to the watch, a motor that rotates only in one direction must be used due to limitations in the specifications of the motor that drives the hands (limitation of the operating voltage of the watch, etc.). It may be unidirectional (forward direction only).

In such a one-way display information correction operation, if the amount of correction by the continuous correction operation is large, there is a high possibility that the correction position intended by the user will be passed if the continuous correction operation is mistakenly performed. .
In order to recover from such overshoot, the reverse operation is optimal. However, as described above, the display information whose display means changes only in one direction cannot be operated to return in the reverse direction. For this reason, it is necessary to move the display means to the intended position by a single correction operation, and the correction operation becomes complicated.
On the other hand, in the present invention, since the continuous correction amount is the same as the single correction amount, even if the continuous correction operation is mistakenly performed, the movement is limited to the single correction amount. It is possible to prevent the intended correction position from going too far and improve the correction operability.

In the electronic timepiece according to the aspect of the invention, it is preferable that the control unit sets the continuous correction amount to the same correction amount as the single correction amount when the total correction amount of the display information is equal to or less than a preset setting value. .
If the total amount of corrections in the display information is small, increasing the continuous correction amount is likely to pass the correction position intended by the user if the continuous correction operation is mistakenly performed.
On the other hand, in the present invention, since the continuous correction amount is the same as the single correction amount, even if the continuous correction operation is mistakenly performed, the movement is limited to the single correction amount. It is possible to prevent the intended correction position from going too far and improve the correction operability.
Furthermore, since the total number of correction amounts of the display information is small, even if the continuous correction amount is the same as the single correction amount, the burden of the user's correction operation is not increased, and a reduction in correction operability can be prevented.

In the electronic timepiece according to the aspect of the invention, when the required time when the total number of correction amounts of the display information is continuously corrected is equal to or less than a preset time, the control unit sets the continuous correction amount to the single correction amount. The correction amount is preferably the same as the correction amount.
When the display means corrects the total correction amount, that is, when the display means makes a round (the time it takes for the display means to go around and return to the original position) (for example, the driving frequency of the pointer indicating the display information) Can be easily corrected by a single correction operation alone, or when the total amount of correction of display information is small.

In addition, when the user has instructed the continuous correction operation by mistake, if the continuous correction amount is large, the display means makes a round in a short time, so that it is difficult to adjust the correction position intended by the user.
On the other hand, in the present invention, since the continuous correction amount is the same as the single correction amount, even if the continuous correction operation is mistakenly performed, the movement is limited to the single correction amount. It is possible to prevent the intended correction position from going too far and improve the correction operability.
Furthermore, since the total number of correction amounts of the display information is small, even if the continuous correction amount is the same as the single correction amount, the burden of the user's correction operation is not increased, and a reduction in correction operability can be prevented.

In the electronic timepiece of the invention, the control means displays the display information on information set by receiving a satellite signal, information on the amount of movement of the display means at the time of correction not being fixed, and display on the display means at the time of correction. When the displayed information is any information that does not have continuity, the continuous correction amount is preferably set to the same correction amount as the single correction amount.
Information set by receiving a satellite signal includes, for example, time zone information. As information that the amount of movement of the display means at the time of correction is not constant, for example, when the day of the week is displayed in a fan shape and the pointer is moved in one direction from the reference position, the scale moves on each day and moves to the end Is information that moves to the reference position at once. Information that is not continuous in the display information displayed on the display means at the time of correction includes time zone information that is corrected from -12 hours to 0 hours after being corrected from 0 hours to +14 hours.

  In the present invention, since the correction amount of the display information is not constant, it may be difficult to correct the position intended by the user if the continuous correction amount is increased. On the other hand, in the present invention, since the continuous correction amount is the same as the single correction amount, even if the continuous correction operation is mistakenly performed, the movement is limited to the single correction amount. It is possible to prevent the intended correction position from going too far and improve the correction operability.

Thereby, the circuit board 120 and the antenna body 110 inside the storage space are connected by the antenna connection pins 115.

[Rotation detector]
The circuit board 120 is provided with a rotation detector 59 that detects the rotation of the crown 50.
The rotation detector 59 detects the direction and amount of rotation when the crown 50 is rotated.
As shown in FIG. 4, the crown 50 includes a winding stem 51 and a switch wheel 52 whose center is fixed to the winding stem 51. The switch wheel 52 is provided with a plurality of teeth (three in this embodiment having an interval of 120 degrees) on the outer peripheral edge.

As shown in FIG. 4, the rotation detector 59 includes a moving body 58, a contact spring 57 having contacts 57A and 57B, a first switch 56A, and a second switch 56B.
The moving body 58 is provided so as to be movable in the tangential direction of the outer peripheral edge of the switch wheel 52 on the moving path of the teeth 53 of the switch wheel 52. When the teeth 53 of the switch wheel 52 come into contact with each other, the moving body 58 moves in the rotation direction of the switch wheel 52 (the rotation operation direction of the crown 50) as shown in FIG.

  The contact spring 57 is fixed to the moving body 58 and biases the moving body 58 toward the initial position (position shown in FIG. 4A) on the moving path of the teeth 53. Therefore, when the crown 50 is rotated (right rotation, normal rotation direction), the moving body 58 is moved by the teeth 53 as shown in FIG. Further, when the crown 50 is rotated in the same direction, the moving body 58 is moved by the teeth 53, so that the contact spring 57 is bent and the teeth 53 move over the moving body 58. And if the tooth | gear 53 leaves | separates from the moving body 58, the moving body 58 will return to an initial position with the urging | biasing force of the contact point spring 57. FIG.

The contact spring 57 is connected to a control device 150 (see FIG. 5), which will be described later, and is applied with a predetermined power supply voltage (VDD). Therefore, when the moving body 58 moves to the first switch 56A side, one contact 57A of the contact spring 57 contacts the first switch 56A. When the moving body 58 moves to the second switch 56B side, the other contact 57B of the contact spring 57 contacts the second switch 56B.
The first switch 56A and the second switch 56B are respectively connected to the control device 150, and the control device 150 can detect that the contact spring 57 has also contacted the first switch 56A and the second switch 56B.

In such a rotation detector 59, when the crown 50 is rotated to the right, the contact 57A and the first switch 56A come into contact with each other, whereby the first switch 56A is turned on, and the contact spring via the first switch 56A. The voltage signal (VDD) 57 is input to the control device 150 as a detection signal.
Similarly, when the crown 50 is rotated in the reverse direction (counterclockwise), the contact 57B and the second switch 56B come into contact with each other, so that the second switch 56B is turned on, and the contact is made via the second switch 56B. The voltage signal (VDD) of the spring 57 is input to the control device 150 as a detection signal.
Therefore, it is possible to detect the rotation direction of the crown 50 by determining whether the first switch 56A is turned on or the second switch 56B is turned on.
In the present embodiment, as described above, since the teeth 53 are arranged at intervals of 120 degrees, the rotation detection unit 59 outputs a detection signal to the control device 150 every time the crown 50 is rotated 120 degrees.

The crown 50 is configured to be movable in three stages of 0 to 2 stages in the axial direction of the winding stem 51. The rotation detection unit 59 includes a third switch 55A (see FIG. 5) and a fourth switch 55B (see FIG. 5) that output a signal corresponding to the number of stages from which the crown 50 has been pulled out to the control device 150.
The third switch 55A outputs a drawing detection signal to the control device 150 when the crown 50 is pulled out by one stage. The fourth switch 55B outputs a drawer detection signal to the control device 150 when the crown 50 is pulled out by two stages.
The control device 150 can determine the number of extraction stages of the crown 50 by determining the switch from which the extraction detection signal is output.

As shown in FIG. 2, the outermost periphery of the dial 11 has a scale that divides the outer periphery into 60 divisions and a 1/5 scale that divides the scale into 5 divisions. Using this scale, the hand 21 displays “second” of the chronograph function, the hand 22 displays “minute” of the internal clock, and the hand 23 displays “hour” of the internal clock. The chronograph function can be used by operating any one of the A button 61, the B button 62, the C button 63, and the D button 64.

On the outer periphery of the circular first small window 70 provided on the dial 11, a scale that divides the outer periphery into 60 divisions and numbers in increments of 10 from “10” to “60” are written. The pointer 71 displays “minute” of the chronograph function using this scale.
On the outer periphery of the circular second small window 80 provided on the dial 11, a scale that divides the outer periphery into 60 divisions and numbers from “0” to “11” are written. The pointer 81 displays “second” of the internal clock using this scale.

The alphabet “Y” is written at the 52 second position of the second small window 80, and the alphabet “N” is written at the 38 second position. This alphabetic character corresponds to a display indicating the information acquisition result provided in the small window, and the acquisition result (Y: successful reception (acquisition) of various information (first information and second information) based on the satellite signal received from the satellite, N: reception (acquisition failure)) and automatic reception of satellite signals (Y: automatic reception ON, N: automatic reception OFF).
When the user shifts to the information acquisition result display mode by operating the B button 62, the pointer 81 indicates either “Y” or “N”, and the first information and the second information based on the satellite signal are displayed. Displays the acquisition result of. Further, the user can set ON / OFF of automatic reception of satellite signals by operating the A button 61 and the B button 62 and setting the pointer 81 to “Y” or “N”.

The second small window 80 is located in the left half region of the dial 11 when viewed from the top, that is, when the dial 11 is viewed from the front side. Therefore, the alphabets “Y” and “N” can be easily recognized even when the wide pointers 22 and 23 are positioned so as to overlap the second small window 80. The second small window 80 is disposed in the vicinity of the outer edge of the left half region.
In this embodiment, the notation “Y” is provided at the position of 52 seconds and the notation “N” is provided at the position of 38 seconds. However, the present invention is not limited to this. The notation “Y” and “N” is preferably provided at a position where it can be easily seen according to the position where other small windows such as a reception result display are provided. For example, when the second small window 80 is located in the right half area of the dial 11, the alphabets “Y” and “N” are arranged near the outer edge of the right half area of the second small window 80. You may do it.

The outer periphery of the circular third small window 90 provided on the dial 11 will be described. In the following description of the outer peripheral range, “n-hour direction” (n is an arbitrary natural number) is the direction when the circular outer periphery is viewed from the center of the third small window 90.
On the outer periphery of the range from the 12 o'clock direction to the 6 o'clock direction of the third small window 90, a scale that divides this range into 6 and numbers from “0” to “5” are written. The pointer 91 displays “hour” of the chronograph function using this scale. In the chronograph function, it is possible to measure time up to 5 hours 59 minutes 59 seconds using the hands 21, 71, 91.

  On the outer periphery of the third small window 90 in the range from 6 o'clock to 7 o'clock, the letter “DST” and the symbol “◯” are written. DST (daylight saving time) means daylight saving time. These letters and symbols represent the setting of daylight saving time (DST: daylight saving time ON, ○: daylight saving time OFF). When the user operates the crown 50 and the B button 62 and sets the hands 91 to “DST” or “◯”, the electronic timepiece 10 can be set to ON / OFF for daylight saving time.

  On the outer periphery of the third small window 90 in the range from 7 o'clock to 9 o'clock, a crescent sickle-shaped symbol 92 is formed along the circumference, with the base end in the 9 o'clock direction being thick and the tip in the 7 o'clock direction being thin. It is written. The symbol 92 is a power indicator of the secondary battery 130 (see FIG. 3), and the pointer 91 indicates one of the base end, the tip end, and the middle according to the remaining battery level. The pointer 91 indicates the power indicator when the electronic timepiece 10 displays the normal time or when the time is manually adjusted.

  On the outer periphery of the third small window 90 in the range from 9 o'clock to 10 o'clock, an airplane-shaped symbol 93 is written. This symbol represents the airplane mode. When aircraft take off and landing, the reception of satellite signals is prohibited by the Aviation Law. The user can stop the reception of the satellite signal of the electronic timepiece 10 by operating the A button 61 and selecting the symbol 93 (in-flight mode) with the hands 91.

On the outer periphery of the third small window 90 in the range from the 10 o'clock direction to the 12 o'clock direction, a number “1” and a symbol “4+” are written. These numbers and symbols represent the contents (reception mode) of satellite signal reception. “1” receives GPS time information and the internal time is corrected (time measurement mode), “4+” receives GPS time information and orbit information, and the internal time and the time zone described later are corrected. (Positioning mode).
In addition, the electronic timepiece 10 performs a reception operation when the user presses the B button 62, and sets the reception mode according to the time for which the B button 62 is pressed.

  When the B button 62 is pressed for a first set time (for example, 3 seconds to less than 6 seconds) during normal time display, the electronic timepiece 10 sets the pointer (second hand) 81 for indicating the time by the drive mechanism 140 to 0. Driving to the second position, the pointer 91 is driven to the position “1” in FIG. When the B button 62 that has been pressed for 3 seconds or more is released within the first set time (less than 6 seconds after starting to be pressed), the electronic timepiece 10 executes reception processing in the timekeeping mode.

On the other hand, when the B button 62 is kept pressed within the first set time without being released, the electronic timepiece 10 is at the 0 second position when the first set time is exceeded (when 6 seconds have elapsed). The pointer 81 is driven forward to the 30-second position, and the pointer 91 is driven to the “4+” position in FIG. Then, the electronic timepiece 10 executes reception processing in the positioning mode.
Furthermore, when the B button 62 is pressed for a third set time (for example, less than 3 seconds) during normal time display, the electronic timepiece 10 displays the reception result of the satellite signal received immediately before, as will be described later.

  The calendar small window 15 is provided in the opening part which opened the dial 11 in the rectangular shape, and the number printed on the calendar wheel 16 can be visually recognized from the opening part. This number represents the “day” of the date.

Here, the relationship among Coordinated Universal Time (UTC), time difference, standard time, and time zone will be described.
A time zone is an area that uses a common standard time, and currently there are 40 types of time zones. Each time zone is distinguished by a time difference between standard time and UTC. For example, Japan belongs to a time zone of +9 hours using standard time which is 9 hours ahead of UTC. The standard time used in each time zone can be obtained from UTC and the time difference between UTC.

  As described above, the dial 11 is engraved with a scale indicating 60 minutes and seconds, and the dial ring 40 surrounding the outer periphery of the dial 11 has a coordinated universal time ( Time difference information 45 representing the time difference from UTC is represented by a number and a symbol “·” other than a number. The numerical time difference information 45 is an integer time difference, and the time difference information 45 of the symbol “·” represents a time difference other than an integer. For example, “·” between “3” and “4” indicates that the time difference is “3:30”. Two “•” are set between “5” and “6”, and the time differences indicate “5:30” and “5:45”, respectively. In this embodiment, it is set so that a total of 40 time zones can be selected.

The time difference between the internal time displayed by the hands 22, 23, 81 and UTC can be confirmed by the time difference information 45 indicated by the hands 21 by operating the crown 50.
The bezel 32 provided around the dial ring 40 has city information 35 representing the representative city name of the time zone using the standard time corresponding to the time difference of the time difference information 45 written on the dial ring 40. Is also written in the time difference information 45. Here, the notation of the time difference information 45 and the city information 35 is referred to as a time zone display 46. In this embodiment, a time zone display 46 equal to the number of time zones used all over the world is shown.

[Circuit configuration of electronic watch]
FIG. 5 is a block diagram showing a circuit configuration of the electronic timepiece 10.
The electronic timepiece 10 includes the display device 20, the input device 69, the reception device 122, and the control device 150 described above, and also includes a timer device 159 and a storage device 160.

[Receiver]
The receiving device 122 is a load driven by the electric power stored in the secondary battery 130. When driven by the control device 150, the receiving device 122 receives a satellite signal transmitted from the GPS satellite 8 through the antenna body 110. Then, when receiving the satellite signal is successful, the receiving device 122 transmits information such as the acquired orbit information and GPS time information to the control device 150. On the other hand, when the reception of the satellite signal fails, the receiving device 122 transmits information to that effect to the control device 150. Note that the configuration of the receiving device 122 is the same as the configuration of a known GPS receiving circuit, and a description thereof will be omitted.

[Time measuring device]
The time measuring device 159 includes a crystal resonator driven by the electric power stored in the secondary battery 130, and updates time data using a reference signal based on an oscillation signal of the crystal resonator.

[Storage device]
As illustrated in FIG. 6, the storage device 160 includes a time data storage unit 161, a time zone data storage unit 167, a scheduled reception time storage unit 168, and a display correction data storage unit 169.

  The time data storage unit 161 stores reception time data 162, leap second update data 163, internal time data 164, clock display time data 165, and time zone data 166.

  The reception time data 162 stores time information (GPS time) acquired from satellite signals. The reception time data 162 is normally updated every second by the timing device 159, and is corrected by the acquired time information (GPS time) when a satellite signal is received.

  The leap second update data 163 stores at least current leap second data. That is, “subframe 4, page 18” of the satellite signal includes “current leap second”, “leap second update week”, “leap second update date”, “updated leap second” as data relating to leap seconds. Each data of “second” is included. Among these, in the present embodiment, at least “current leap second” data is stored in the leap second update data 163.

  The internal time data 164 stores internal time information. This internal time information is updated by the GPS time stored in the reception time data 162 and the “current leap second” stored in the leap second update data 163. That is, the internal time data 164 stores UTC (Coordinated Universal Time). When the reception time data 162 is updated by the timing device 159, the internal time information is also updated.

  The clock display time data 165 stores time data obtained by adding the time zone data (time zone information, time difference information) of the time zone data 166 to the internal time information of the internal time data 164. The time zone data 166 is set with position information obtained when received in the positioning mode. The time zone data 166 can also be set manually by rotating the crown 50, as will be described later.

  The time zone data storage unit 167 stores position information (latitude, longitude) and time zone information (time difference information) in association with each other. Therefore, when the position information is acquired in the positioning mode, the control device 150 can acquire time zone data based on the position information (latitude, longitude).

  The time zone data storage unit 167 further stores a city name and time zone data in association with each other. For this reason, when the pointer 21 is moved by operating the input device 69 and the user selects a city name to know the local time, the control device 150 sets the city name set by the user to the time zone data storage unit 167. The time zone data corresponding to the city name may be retrieved and set in the time zone data 166.

  The scheduled reception time storage unit 168 stores the scheduled reception time for executing the scheduled reception process in the timing unit 151. As this scheduled reception time, the time when the forced reception succeeded last time is stored.

[Display correction data storage section of storage device]
The display correction data storage unit 169 stores display correction data used for operations in the display correction unit 155 of the control device 150 described later.
As shown in FIG. 7, the display correction data storage unit 169 has a single correction amount 169B, which is a correction amount in a single correction operation, for each display correction mode 169A, that is, for each display information to be corrected. A continuous correction amount 169C, which is a correction amount, a crown stage number 169D for selecting a display correction mode, and a button operation 169E are stored.

  Here, the single correction amount 169B is a single correction amount, that is, “1”. Note that “1” of the single correction amount 169B is the minimum correction amount of each display information. For example, as shown in FIG. 2, since the time zone information 45 of the dial ring 40 is set with the above-mentioned total 40 time zones, the total number of correction amounts is “40”, and the single correction amount “ “1” is for one time zone. Since the display positions of the time zones on the dial ring 40 are not equally spaced, the hand movement angle of the pointer 21 by a single correction signal with a single correction amount is not constant. For example, the hand movement angle of the pointer 21 when moving from the time zone “2” to “3” (the number of driving steps of the 5-second chronograph hand motor 144) and the next “•”, that is, “3:30” from “3”. ”Is different from the hand movement angle of the pointer 21 (the number of driving steps of the 5-second chronograph hand motor 144) when moving to“ ”.

  If the display correction mode 169A is the “time zone selection mode”, the single correction amount 169B is “1” and the continuous correction amount 169C is “1”. The operation for selecting the “time zone selection mode” is “1” in the crown stage number 169D and “none” in the button operation 169E.

Of the items stored in the display correction data storage unit 169, the single correction amount 169B is basically a single correction, so “1” is basically set.
On the other hand, the continuous correction amount 169C is set based on the correction target of each display correction mode 169A and the total number of correction amounts. Here, the total number of correction amounts is the amount of correction until the hands 21, 22, 23, 71, 81, 91 and the calendar wheel 16 as display means return to their original positions.

For example, in the “1/5 second chronograph hand correction mode”, the total correction amount “300” of the pointer 21 to be corrected is set as the continuous correction amount 169C.
Similarly, in the “date correction mode”, the total correction amount “31” of the calendar wheel 16 to be corrected is set as the continuous correction amount 169C.

On the other hand, some display correction modes are corrected with the same correction amount as the single correction mode even if the continuous correction operation is performed, and as a result, the continuous correction is not executed.
For example, in the “time zone selection mode”, “1”, which is the same as the single correction amount 169B, is set as the continuous correction amount 169C.
This is a time zone display 46 (see FIG. 2) on the dial ring 40 indicated by the pointer 21 to be corrected in the “time zone selection mode”. Based on the presence of discontinuous parts (between “−4” and “−5”, between “5” and “6”, etc.).
Such exclusion of the continuous correction operation includes 1) information set by receiving satellite signals (for example, time zone information), and 2) information in which the amount of movement of the display means at the time of correction is not constant (for example, time zone) Information or day-of-week information indicated by a pointer arranged in a fan shape and reciprocating) 3) Information that is not continuously displayed on the display means (time zone information is +12 hours followed by -12 hours) Are performed in the same manner.

[Control device]
The control device 150 is a control unit, and includes a CPU that controls the electronic timepiece 10 as shown in FIG.
The control device 150 includes a time measuring unit 151, a positioning unit 152, an automatic time correcting unit 153, a time zone correcting unit 154, a display correcting unit 155, a crown step number determining unit 156, and a crown rotation operation determining unit 170. .

[Timekeeping section]
The time measurement unit 151 operates the reception device 122 to perform reception processing in the time measurement mode.
In the reception process in the time measurement mode, the time measurement unit 151 acquires at least one GPS satellite 8 by the receiving device 122, receives a satellite signal transmitted from the GPS satellite 8, and acquires time information.
In the present embodiment, the time measurement unit 151 performs reception processing in the time measurement mode in automatic reception processing and manual reception processing.

There are two types of automatic reception processing: scheduled automatic reception processing and optical automatic reception processing. In other words, the time measuring unit 151 operates the receiving device 122 when the internal time data 164 being timed is the scheduled reception time stored in the scheduled reception time storage unit 168, so that the scheduled time in the time measurement mode is reached. Performs automatic reception processing.
In addition, the time measuring unit 151 operates the receiving device 122 to measure the time when the generated voltage or generated current of the solar panel 135 exceeds the set value and it can be determined that the solar panel 135 is irradiated with sunlight outdoors. Performs automatic optical reception in mode. Note that the number of processes for operating the receiving device 122 in the power generation state of the solar panel 135 may be limited to once a day.
As described above, the manual reception process is executed by the user performing the forced reception operation by pressing the B button 62 of the input device 69 for the first set time, and the time measurement unit 151 operates the reception device 122 to operate the time measurement mode. Perform manual reception processing at.

[Positioning unit]
As described above, the positioning unit 152 operates the receiving device 122 to perform the receiving process in the positioning mode when the user performs the forced receiving operation by pressing the B button 62 of the input device 69 for the second set time.
The time measurement mode, positioning mode, and leap second reception mode may be selected and set in advance, and the reception process may be performed in the set mode during the automatic reception process (scheduled automatic reception process or optical automatic reception process). .

  When the positioning unit 152 starts reception processing in the positioning mode, the receiving device 122 captures at least three, preferably four or more GPS satellites 8 and receives satellite signals transmitted from the respective GPS satellites 8. Calculate and acquire location information. The positioning unit 152 can also acquire time information at the same time when receiving a satellite signal.

[Automatic time correction section]
The automatic time correction unit 153 corrects the reception time data 162 with the acquired time information when the time information is successfully acquired in the reception processing of the time measurement unit 151 or the positioning unit 152. By correcting the reception time data 162, the internal time data 164 and the clock display time data 165 are also corrected. When the clock display time data 165 is corrected, the current time display on the display device 20 synchronized with the clock display time data 165 is also corrected by the hand position detection means.

[Time zone correction section]
When the positioning unit 152 calculates the position information and succeeds in acquisition, the time zone correction unit 154 sets time zone data based on the acquired position information (latitude, longitude). Specifically, time zone data (time zone information, that is, time difference information) corresponding to the position information is selected and acquired from the time zone data storage unit 167 and stored in the time zone data 166.
For example, since Japan Standard Time (JST) is a time (UTC + 9) that is 9 hours ahead of UTC, if the location information acquired by the positioning unit 152 is Japan, the time zone correction unit 154 Time difference information (+9 hours) in Japan standard time is read from the data storage unit 167 and stored in the time zone data 166.

  After setting the time zone information, the time zone correction unit 154 corrects the clock display time data 165 using the time zone data. Therefore, the clock display time data 165 is a time obtained by adding the time zone data to the internal time data 164 which is UTC.

[Display correction section]
The display correction unit 155 drives the drive mechanism 140 separately from the normal operation according to the operation of the crown 50 by the user, and corrects the display of the display device 20 (steps S85 to S88 in FIG. Abbreviated as “S”).
For example, when the time of the clock display time data 165 stored in the storage device 160 is different from the display time of the hands 22 and 23 on the display device 20 for some reason, it is driven according to the operation of the crown 50. The hour / minute hand motor 142 of the mechanism 140 is driven to set the hands 22 and 23 to the reference position (0: 0 position). When the crown 50 is pushed into the 0th stage to cancel the reference position alignment mode, the hands 22 and 23 are automatically corrected to the position indicating the time of the time data 165 for clock display.

When correcting the display, the display correcting unit 155 changes the display position of one of the pointers and the like of the display device 20 as a display correction operation mode by unit of the crown 50 as a display correction operation mode. “Correction mode” and “continuous correction mode” in which the display position is continuously changed and stopped at an arbitrary display position by the operation of the crown 50.
In the “single correction mode”, the display correction unit 155 outputs a single correction signal to the drive mechanism 140 to correct the display device 20 by a single correction amount (one unit).
In the “continuous correction mode”, the display correction unit 155 outputs a continuous correction signal to the drive mechanism 140 to correct the display device 20 with the continuous correction amount.

In order to perform such a display correction operation, in the control device 150, the crown stage number determination unit 156 and the crown rotation operation determination unit 170 detect a user operation on the crown 50 (S81 to S90 in FIG. 8 described later).
In control device 150 (display correction unit 155, crown step number determination unit 156 and crown rotation operation determination unit 170), “initial mode”, “fast forward determination mode”, and “fast forward stop determination mode” are used as signal determination modes. "Is set.

The “initial mode” is a mode executed when the rotation operation of the crown 50 is not detected. When the first rotation operation of the crown 50 is detected in the “initial mode”, the process proceeds to the “fast turn determination mode”.
The “fast turn determination mode” is a mode for detecting whether or not the crown 50 has been continuously rotated. When the continuous rotation operation of the crown 50 in the “fast turn determination mode”, that is, a plurality of continuous rotation operations in the same direction within a predetermined time, is detected, the “continuous correction mode” is set as the display correction operation mode. The Further, the signal determination mode shifts to the “fast-turn stop determination mode” in order to detect whether the stop operation during the continuous correction has been performed.

On the other hand, when a plurality of continuous rotation operations in the same direction are not detected within a predetermined time in the “fast rotation determination mode”, that is, when one rotation operation is detected, the display correction operation mode includes “ "Single correction mode" is set. Further, the signal determination mode shifts to the “initial mode”.
Therefore, the “continuous correction mode” and “single correction mode” that are display correction operations are performed during the execution of the “fast-forward determination mode” and “fast-forward determination mode” for any correction target of the display device 20. The These specific operations will be described later.

[Crown stage number determination unit]
The crown stage number determination unit 156 determines whether or not the crown 50 has been pulled out based on a pull-out detection signal from the third switch 55A or the fourth switch 55B in the rotation detection unit 59.
When the crown 50 is not pulled out, both the third switch 55A and the fourth switch 55B are turned off. In this case, the crown stage number determination unit 156 determines that the crown 50 has not been pulled out (the number of drawer stages is “0”).

When the crown 50 is pulled out by one stage, the third switch 55A is turned on, the fourth switch 55B is turned off, and a drawer detection signal is input from the third switch 55A to the control device 150. In this case, the crown stage number determination unit 156 determines that the pull-out stage number of the crown 50 is “1”.
When the crown 50 is pulled out by two stages, the third switch 55A is turned off, the fourth switch 55B is turned on, and a drawer detection signal is input from the fourth switch 55B to the control device 150. In this case, the crown stage number determination unit 156 determines that the pull-out stage number of the crown 50 is “2”.

[Crown rotation operation determination unit]
The crown rotation operation determination unit 170 includes a fast rotation determination timer 171, a continuous correction counter 172, and a signal determination unit 173.
The signal determination unit 173 determines whether the current signal determination mode in the control device 150 is any one of “initial mode”, “fast-forward determination mode”, and “fast-forward stop determination mode”.

The fast-turn determination timer 171 counts down according to the passage of time until the count value becomes 0 from a preset initial value.
The fast-turn determination timer 171 starts counting down when the first detection signal (first detection signal) is input from the rotation detection unit 59 to the control device 150 when the signal determination mode is “initial mode”. (See FIG. 10 described later).
The initial value of the fast-forward determination timer 171 is set to a preset fast-rotation determination time (for example, 160 ms).

The second detection signal (second detection signal) is input from the rotation detection unit 59 to the control device 150 until the countdown of the fast-forwarding determination timer 171 reaches the count value 0, and is continuously performed twice in the same direction. When a rotation operation is detected, it is determined that a continuous rotation operation (fast-forward operation) of the crown 50 has been performed. For this reason, the fast-forwarding determination timer 171 stops the countdown (S119 in FIG. 11 described later). At this time, the fast-forwarding determination timer 171 resets the counter value (returns to the initial value of 160 ms).
On the other hand, when the time for fast-turn determination elapses (counter value becomes 0) without detecting the second detection signal from the detection of the first detection signal, one operation (single-turn operation) of the crown 50 is performed. Since it has been determined that it has been performed, the fast-forwarding determination timer 171 stops counting and resets the counter value (returns to the initial value of 160 ms).

The continuous correction counter 172 sets a correction amount in the continuous correction mode, and the display correction unit 155 performs display correction (S85 to S88 in FIG. 8 described later) until the count value becomes 0 from the preset initial value. Is counted down (see S89 in FIG. 8 described later).
The continuous correction counter 172 receives the second detection signal (second detection signal) from the rotation detection unit 59 to the control device 150 and continues in the same direction when the signal determination mode is the “fast rotation determination mode”. When the number of rotation operations is detected, a continuous correction amount corresponding to the type of information to be corrected is set as an initial value (see FIG. 11 described later).
The initial value of the continuous correction counter 172 is set with reference to the continuous correction amount 169C in FIG.

[Basic operation of control device]
In the electronic timepiece 10, when the user manually operates the input device 69 (the crown 50 and the buttons 61 to 64), the control device 150 executes processing according to the operation.
For example, when the crown 50 is operated, a manual correction process for correcting the display time according to the operation is performed. Further, when the B button 62 is pressed for the first set time, the manual reception process in the timekeeping mode is executed, and when the B button 62 is pressed for the second set time, the manual reception process in the positioning mode is executed.

[Display correction operation]
Based on the flowchart of FIG. 8, the display correction process of the display device 20 executed by the user performing an operation of pulling out the crown 50 to the first stage or the second stage will be described.
In FIG. 8, the display correction unit 155 of the control device 150 monitors the output of the crown stage determination unit 156, and if the crown 50 is not “1” or “2” (if the drawer stage number is “0”). Monitoring) is continued (S81). On the other hand, when the pull-out stage number of the crown 50 becomes “1” or “2” (Yes in S81), the display correction process after S82 is started.

In FIG. 8, when the crown 50 is pulled out to the first stage or the second stage, a change in the number of stages is detected by the crown stage number determination unit 156, and it is determined Yes in S81. For this reason, the control device 150 sets the signal determination mode to “initial mode” (S82), and instructs the drive mechanism 140 to stop driving the pointer (S83).
The control device 150 confirms whether the crown 50 has been returned to the 0th stage (S84), and if it has been returned to the 0th stage (Yes in S84), the normal movement by the drive mechanism 140 is resumed (S80). . On the other hand, if not returned to the 0th stage, the control device 150 causes the crown rotation operation determination unit 170 to execute the rotation operation determination processing of the crown 50 (S90).

[Crown rotation operation determination processing]
As shown in FIG. 9, the crown rotation operation determination process S90 executed by the crown rotation operation determination unit 170 branches to a process corresponding to each mode according to the current signal determination mode.
If the current signal determination mode is “initial mode” (Yes in S91), an initial mode signal determination process S100 (see FIG. 10) is executed.
If the current signal determination mode is “fast-forward determination mode” (Yes in S92), fast-forward determination mode signal determination processing S110 (see FIG. 11) is executed.
If the current signal determination mode is other than that, that is, the “fast-turn stop determination mode” (No in S91 and S92), the fast-turn stop determination mode signal determination process S120 (see FIG. 12) is executed.

[Initial mode signal judgment processing]
In the initial mode signal determination process S100, as shown in FIG. 10, the control device 150 first determines whether or not the first switch 56A is “ON” (S101).
If the first switch 56A is “ON” (Yes in S101), it is determined that there is a rotation operation of the crown 50 (first detection signal) and the rotation direction is “right” (S102).

On the other hand, when it determines with No by S101, the control apparatus 150 determines whether the 2nd switch 56B is "ON" (S105). If the second switch 56B is “ON” (Yes in S105), it is determined that there is a rotation operation of the crown 50 and the rotation direction is “left” (S106).
In this embodiment, when the crown is rotated to the right, the display device 20 such as the pointer is corrected in the normal rotation direction, and when it is rotated in the left direction, it is set to be corrected in the reverse rotation direction.

Then, after the processing of S102 and S106, the signal determination mode is set to “fast rotation determination mode” (S103), and the fast rotation determination timer 171 is started (S104).
If No in S105, neither switch 56A, 56B is input, so the initial mode signal determination process S100 is terminated and the process returns to the process of FIG. Then, the crown rotation operation determination process S90 of FIG. 9 is also ended, and the process returns to the process of FIG.

[Judgment processing of correction command]
In FIG. 8, when returning from the crown rotation operation determination process S90, the control device 150 determines whether there is a single correction command or a continuous correction command (S85). Here, through the crown rotation operation determination process S90 and the initial mode signal determination process S100, either of the switches 56A and 56B remains in the “initial mode”, or one of the switches 56A and 56B is input once. Is detected and is changed to the “fast turn determination mode”, and since there is neither a single correction command nor a continuous correction command, it is determined No in S85.
For this reason, the processing from S84 (confirmation of whether crown 50 has been returned to the 0th stage) is repeated without executing S86 to S89 described later.

  Then, when the crown rotation operation determination process S90 is executed again, if the “early rotation determination mode” is set in the previous initial mode signal determination process S100 (see FIG. 10), it is determined No in S91. Since it is determined Yes in S92, the fast rotation determination mode signal determination process S110 (see FIG. 11) is executed.

[Fast rotation judgment mode signal judgment processing (for single correction operation)]
In the fast-forwarding determination mode signal determination process S110, as shown in FIG. 11, first, it is determined whether the fast-forwarding determination timer 171 started in S104 of the initial mode signal determination process S100 has timed out (S111).
If the fast-turn determination timer 171 has timed out (Yes in S111), the rotation direction of the crown 50 is determined from the first switch 56A and the second switch 56B in the same manner as S101 and S105 described above (S112), and the rotation direction Is “right” (Yes in S112), “forward rotation / single correction command” is set (S113), and if the rotation direction is “left” (No in S112), “reverse rotation / single correction command”. Is set (S114).
Then, the signal determination mode is returned to the “initial mode” (S115), the determination mode signal determination process S110 is terminated, and the process returns to the process of FIG. Then, the crown rotation operation determination process S90 in FIG. 9 is also ended, and the process returns to S85 in FIG.

[Correction command judgment processing (for single correction operation)]
In FIG. 8, the control device 150 determines whether there is a single correction command or a continuous correction command (S85). Here, since the “forward rotation direction / single correction command” or “reverse rotation direction / single correction command” is set by the fast-forwarding determination mode signal determination processing S110, it is determined Yes in S85.
Subsequently, it is determined whether forward rotation or reverse rotation (S86), and in the case of normal rotation (Yes in S86), a single correction signal for normal rotation is output to a motor that drives the display device 20 such as a pointer to be corrected. The pointer or the like is moved to the next display position (S87). Also. In the case of reverse rotation (No in S86), a single correction signal for reverse rotation is output to the motor that drives the display device 20 such as the pointer to be corrected, and the pointer is moved to the previous display position (S88). At this time, since the correction amount of the single correction signal is a single correction amount, the display device 20 such as a pointer is corrected to move to the next scale.

  Thereafter, the continuous correction counter 172 is set to “−1” (S89). Since the continuous correction counter 172 is used for control during the continuous correction operation, it is not directly related to the single correction operation. Thereafter, the processing from S84 is repeated.

[Fast rotation judgment mode signal judgment processing (for continuous correction operation)]
Returning to FIG. 11, if the fast-forwarding determination timer 171 has not timed out, the control device 150 determines whether or not the first switch 56A is ON (S116).

[For right-side continuous correction operation]
If the first switch 56A is “ON”, it means that there has been an additional operation of the crown 50 (second detection signal), and the rotation direction of the operation is determined to be “right”.
Here, the control device 150 checks the rotation direction (S102 or S106) of the first detection signal and determines whether the rotation direction of the first detection signal is “right” (S117).
If the rotation direction of the first detection signal is not “right” (No in S117), the rotation direction of the crown 50 is different between the previous time and the current time. In the state where the first detection signal is turned on by the rotation operation, the process returns to S102 of the initial mode signal determination process S100 (see FIG. 10), and the fast-turn determination mode signal determination process S110 is performed again.

  When the rotation direction of the first detection signal is “right”, the rotation operation of the crown 50 in the right direction has been input twice in succession. Command "is set (S118), and the fast-turn determination timer 171 is stopped (S119). Then, a continuous correction amount corresponding to the current correction target is set in the continuous correction counter 172 (S11A).

Specifically, the display correction unit 155 selects the current correction target from the display correction mode 169A of the display correction data storage unit 169 (see FIG. 7) stored in the storage device 160, and performs continuous correction corresponding to the mode. The quantity 169C is read and set in the continuous correction counter 172. For example, if the display correction mode 169A is the time zone selection mode, the continuous correction amount “1” is set in the continuous correction counter 172. In the 1/5 second chronograph hand correction mode, the continuous correction amount “300” is set in the continuous correction counter 172.
Next, the control device 150 sets the signal determination mode to “fast-turn stop determination mode” (S11B), and ends the fast-turn determination mode signal determination processing S110.

[For continuous correction operation in the left direction]
On the other hand, if it is determined No in S116, it is determined whether the second switch 56B is ON (S11C).
If the second switch 56B is “ON”, the controller 150 determines that the user has added an operation to the crown 50 (second detection signal), and the rotation direction of the operation is “left”.
Here, the control device 150 checks the rotation direction (S102 or S106) of the first detection signal and determines whether the rotation direction of the first detection signal is “left” (S11D).
If the rotation direction of the first detection signal is not “left” (No in S11D), the rotation direction of the crown 50 is different between the previous time and the current time. As a state in which the second detection signal is turned on by the rotation operation, the process returns to S106 of the initial mode signal determination process S100 (see FIG. 10), and the fast turn determination mode signal determination process S110 is performed again.

  When the rotation direction of the first detection signal is “left”, the rotation operation of the crown 50 in the left direction is input twice in succession. Is set (S11E), and the fast-turn determination timer 171 is stopped (S119). Then, as in the case where the clockwise rotation operation of the crown 50 is continuously input twice, the continuous correction amount corresponding to the current correction target is set in the continuous correction counter 172 (S11A), and the signal determination mode is set. The “fast-turn stop determination mode” is set (S11B), and the fast-turn determination mode signal determination process S110 ends.

  When the determination mode signal determination process S110 ends, the process returns to FIG. 9, and the initial mode signal determination process S100 also ends, so the process returns to S85 in FIG. For this reason, it is determined in S85 that there is a continuous correction operation (Yes in S85), the display object is driven in either the forward or reverse direction in S86 to S88, the continuous correction counter 172 is decremented by "-1" in S89, and S84. The process from is continued.

  By repeating the processing from S84, the display device 20 is continuously corrected for each single correction amount. If the “fast rotation stop determination mode” is set in the fast rotation determination mode signal determination process S110 (see FIG. 11), in the crown rotation operation determination process S90 (see FIG. 9) during the continuous correction, S91 and S92. Since both are determined to be No, the fast-turn stop determination mode signal determination process S120 (see FIG. 12) is executed.

[Stop judgment mode signal judgment processing]
In FIG. 12, the crown rotation operation determination unit 170 first determines whether the first switch 56A or the second switch 56B is turned on, that is, whether the rotation operation of the crown 50 has been detected (S121). If there is no rotation operation (No in S121), it is determined whether the continuous correction counter 172 (started in S11A) is “0” (S122).

  If the continuous correction counter 172 is not “0” (No in S122), the fast-turn stop determination mode signal determination process S120 is terminated, and the process returns to the process of FIG. The control device 150 repeats the process of driving the correction target (S86 to S88) and the process of setting the continuous correction counter 172 to “−1” (S89).

[Continuous correction completion operation]
If the continuous correction counter 172 is “0” (Yes in S122), the control device 150 issues a pointer stop command (S123), returns the signal determination mode to the “initial mode”, and quickly turns to the stop determination mode signal determination process. S120 is ended, and the process returns to the process of FIG.
Since the control device 150 has returned to the initial mode, S86 to S88 and S89 that sets the continuous correction counter 172 to “−1” are not performed.

As a result, the continuous correction counter 172 ends the continuous correction operation. As described above, the state of the display device 20 is as follows until the continuous correction counter 172 becomes 0, that is, when the amount of correction set by the continuous correction amount 169C in FIG. 7 is performed.
That is, the display information to be corrected includes a pointer 21 that is a 1/5 second chronograph hand, a pointer 71 that is a minute chronograph hand, a pointer 91 that is an hour chronograph hand, a pointer 81 that is a second hand, and a pointer that is an hour and minute hand. In the case of 22 and 23 and the calendar wheel 16, the continuous correction amount is set to the total number of correction amounts, and thus the continuous correction is performed until each of the rounds returns to the original position.
On the other hand, in the time zone selection mode, the continuous correction amount of the pointer 21 is “1”, which is the same as the single correction amount. Therefore, even when the continuous correction counter 172 becomes zero, the pointer 21 is one step, that is, the next correction amount. It moves only to the position indicating the time zone.

[Continuous correction stop processing]
On the other hand, if there has been an operation on the crown 50 during continuous correction, it is determined Yes in S121, and the control device 150 issues a pointer stop command (S123), returns the signal determination mode to the “initial mode”, stops quickly, and stops. The determination mode signal determination process S120 ends, and the process returns to the process of FIG. Since the control device 150 has returned to the initial mode, the processing of S86 to S88 and the processing of setting the continuous correction counter 172 to “−1” (S89) are not performed.
Thereby, the continuous correction operation by the operation of the crown 50 is interrupted.

[Specific examples of display correction operations]
In the present embodiment, the display correction operation performed according to the processing procedure of FIGS. 8 to 12 described above is executed in the display correction mode of each item in the display correction mode 169A of FIG. 7 described above. Hereinafter, the specific operation example is demonstrated using the schematic diagram of the electronic timepiece 10. FIG.

[Time zone selection mode]
In FIG. 13A, the electronic timepiece 10 of the present embodiment has hands 21, 22, 23, 71, 81, 91 and a calendar wheel 16 as the display device 20, and a crown 50 and an A button 61 as the input device 69. , B button 62, C button 63, and D button 64.
The time zone is set by pointing the relevant part of the time zone display 46 with the pointer 21. Accordingly, the display position of the pointer 21 is changed in the time zone selection mode.

  First, the crown 50 is pulled by one stage in the state of FIG. As a result, the control device 150 enters the “time zone selection mode”. In the display correction data of FIG. 7, the “time zone selection mode” is selected in the display correction mode 169A, the single correction amount 169B is set to “1”, and the continuous correction amount 169C is set to “1”.

In this state, when the crown 50 is operated once (one click) in the right direction (in the direction of the arrow in FIG. 13B), the control device 150 performs the single correction mode in the forward rotation direction based on the flow in FIGS. Execute the correction process.
As a result, as shown in FIG. 13B, the pointer 21 moves in the forward direction by the correction amount “1”, and designates the next time zone in the + direction.
When the pointer 21 is simply corrected in the forward direction and the time zone is changed, the control device 150 changes the current display time according to the selected time zone.
As a result, as shown in FIG. 13C, the hands 22, 23, 81 for displaying the current time are moved to the current time according to the newly selected time zone.

On the other hand, when the crown 50 is operated to the right twice or more (two clicks or more), the control device 150 executes the correction processing in the continuous correction mode in the normal rotation direction based on the flow of FIGS.
However, in the “time zone selection mode”, since the continuous correction amount is “1” and the continuous correction counter 172 immediately becomes “0”, the fast-forward mode is not entered, and the same operation as the single correction operation is performed. Further, when the continuous correction counter 172 becomes “0”, it returns to the “initial mode”, so that the pointer 21 moves by the correction amount “1” even if a plurality of operations have been input so far.
As a result, as shown in FIG. 14 (A), the hand 21 indicates the next time zone in the + direction, and as shown in FIG. 14 (B), the hands 71, 22, and 23 for displaying the current time are It is moved to the current time according to the newly selected time zone.

When the desired time zone is selected, the crown 50 is returned to the normal position (0 stage).
As a result, the time zone selection mode is canceled, and the normal operation of the hands 81, 22, and 23 is resumed with the current time in the newly selected time zone displayed as shown in FIG. 14C.

[Chronograph hand reference alignment mode]
In FIG. 15A, the chronograph function is displayed on the display device 20 with the pointer 21 as a 1/5 second chronograph hand, the pointer 71 as a chronograph minute hand, and the pointer 91 as a chronograph hour hand.
First, as shown in FIG. 15B, the crown 50 is pulled by two steps, and the C button 63 is continuously pressed for 3 seconds or more. As a result, the control device 150 enters the “1/5 second chronograph hand mode”.
In the display correction data of FIG. 7, “1/5 second chronograph hand mode” is selected in the display correction mode 169A, the single correction amount 169B is set to “1”, and the continuous correction amount 169C is set to “300”. .

In this state, as shown in FIG. 16A, when the crown 50 is operated once to the right (for one click), the control device 150 is in the single correction mode in the normal rotation direction based on the flow of FIGS. Perform the correction process. As a result, the pointer 21 moves by the correction amount “1” in the forward rotation direction. Specifically, it moves by the scale of 1/5 second.
On the other hand, if the crown 50 is operated to the right twice or more (two clicks or more) when the pointer 21 is largely deviated from the reference position as shown in FIG. Based on this flow, correction processing in the continuous correction mode in the normal rotation direction is executed. In this case, the pointer 21 is fast-forwarded in the forward direction, and moves until the total number of correction amounts “300”, that is, one rotation. If the crown 50 is rotated during the movement, the fast-forwarding of the hands 21 is stopped. By further performing a simple correction operation from this stop position, the pointer 21 can be moved to a predetermined reference position (0 second position).

When the pointer 21 moves to the reference position, the C button 63 is pressed as shown in FIG. As a result, the control device 150 shifts to the “minute chronograph hand correction mode”.
In the display correction data of FIG. 7, the “minute chronograph hand mode” is selected in the display correction mode 169A, the single correction amount 169B is set to “1”, and the continuous correction amount 169C is set to “60”.

  In this state, when the crown 50 is operated once to the right (for one click) as shown in FIG. 17A, the control device 150 is in the single correction mode in the forward rotation direction based on the flow of FIGS. Perform the correction process. As a result, the pointer 81 moves by the correction amount “1” in the forward rotation direction. Specifically, it moves by the scale of 1 minute.

  On the other hand, as shown in FIG. 17B, when the pointer 71 is greatly deviated from the reference position, if the crown 50 is operated twice or more (two clicks or more) to the right, the control device 150 causes the control device 150 to operate as shown in FIGS. Based on this flow, correction processing in the continuous correction mode in the normal rotation direction is executed. In this case, the pointer 71 is fast-forwarded in the forward direction, and moves until the total number of correction amounts “60”, that is, one rotation. If the crown 50 is rotated during the movement, the fast-forwarding of the hands 71 is stopped. By further performing a single correction operation from this stop position, the pointer 71 can be moved to the intended reference position (0 minute position).

When the pointer 81 moves to the reference position, the C button 63 is pressed as shown in FIG. As a result, the control device 150 shifts to the “hour chronograph hand correction mode”.
In the display correction data of FIG. 7, the “hour chronograph hand mode” is selected in the display correction mode 169A, the single correction amount 169B is set to “1”, and the continuous correction amount 169C is set to “60”.

  In this state, as shown in FIG. 18A, when the crown 50 is operated once to the right (for one click), the control device 150 is in the single correction mode in the forward rotation direction based on the flow of FIGS. Perform the correction process. As a result, the pointer 91 moves by the correction amount “1” in the forward rotation direction. Specifically, it moves for 0.2 hours.

  On the other hand, as shown in FIG. 18B, when the pointer 91 is largely deviated from the reference position, if the crown 50 is operated to the right two times or more (two clicks or more), the control device 150 causes the control device 150 to operate as shown in FIGS. Based on this flow, correction processing in the continuous correction mode in the normal rotation direction is executed. In this case, the pointer 91 is fast-forwarded in the forward rotation direction, and moves until the total correction amount “60”, that is, one rotation. If the crown 50 is rotated during the movement, the fast-forwarding of the hands 91 is stopped. By further performing a single correction operation from this stop position, the pointer 91 can be moved to the intended reference position (0 o'clock position).

As described above, when the hands 21, 71, 91 can be corrected to the reference positions, the crown 50 is returned to the normal position (0 stage) as shown in FIG.
As a result, the reference positioning mode for the chronograph hands is canceled, and the normal operation of the hands 22, 23, 81 indicating the current time is resumed.

[Date correction mode]
In FIG. 19A, the date display function of the electronic timepiece 10 is displayed by the calendar wheel 16 in the display device 20.
First, as shown in FIG. 19B, when the date correction mode is selected such that the crown 50 is pulled down by one step and the C button 63 is continuously pressed for 3 seconds or longer, the control device 150 changes to “date correction mode”. Become.
In the display correction data of FIG. 7, the “date correction mode” is selected in the display correction mode 169A, the single correction amount 169B is set to “1”, and the continuous correction amount 169C is set to “31”.

  In this state, as shown in FIG. 20A, when the crown 50 is operated once to the right (for one click), the control device 150 is in the single correction mode in the forward rotation direction based on the flow of FIGS. Perform the correction process. As a result, the calendar wheel 16 moves in the forward direction by the correction amount “1”. Specifically, it moves only for one day.

  On the other hand, as shown in FIG. 20B, when the crown 50 is operated to the right twice or more (two clicks or more), the control device 150 performs the normal rotation direction continuous correction mode based on the flow of FIGS. Perform the correction process. In this case, the calendar wheel 16 is fast-forwarded in the forward rotation direction and moves until the correction amount “31”, that is, one rotation. If the crown 50 is rotated during the movement, the fast-forwarding of the calendar wheel 16 is stopped. By further performing a simple correction operation from this stop position, the calendar wheel 16 can be moved to the intended display position.

As described above, when the calendar wheel 16 can be corrected to the intended display position, the crown 50 is returned to the normal position (0 stage) as shown in FIG.
As a result, the date correction mode is canceled, and normal operation of the hands 22, 23, 81 indicating the current time is resumed.

In the description of the single correction operation and the continuous correction operation of the present embodiment, the normal rotation direction has been described. However, in the present embodiment, the single correction operation and the continuous correction operation can be similarly performed in the reverse direction. At this time, the rotation direction of the correction operation depends on the rotation direction of the crown 50.
The correction modes of the hands 22 and 23 that are the minute hand and the hour hand, and the correction mode of the hand 81 that is the second hand are omitted, but the outline is as follows. When the crown 50 is pulled out to the second position, a correction standby state is established. Here, if the C button 63 is kept pressed for 3 seconds or more, the mode shifts to the above-mentioned chronograph function pointer correction mode. On the other hand, when the A button 61 is pressed in the standby state, the pointer correction mode at the current time is entered, the pointer 81 as the second hand rotates forward and stops at the 0 second position, and the hands 22 and 23 as the hour / minute hands rotate forward. Stop at the indicated position for the next minute. By operating the crown 50 in this state, the hands 22 and 23 can be corrected to the current time. Thereafter, the crown 50 is pushed back to the 0 stage position in accordance with the timing of the minute in accordance with the time signal or the like, so that each pointer returns to the normal hand movement.

[Effect of the first embodiment]
According to the present embodiment, display information on the display device 20 can be corrected by a rotation operation of the crown 50 that is an operation member. At this time, the single correction mode or the continuous correction mode can be selected by operating the crown 50. Therefore, if the single correction mode is selected, the display device 20 can be moved for each single correction amount, which is the minimum correction unit for each display information in the display device 20, so that fine settings can be made. Moreover, if the continuous correction amount is set to, for example, the total number of correction amounts in the continuous correction mode, the fast-forward correction of the display device 20 can be performed, and a quick correction operation can be performed.

  In the present embodiment, the control device 150 can set the continuous correction amount 169C according to the display correction mode 169A by referring to the display correction data. As a result, the amount of correction can be made variable according to the type of display information, and fine correction can be made according to the total number of correction amounts.

In particular, when the continuous correction amount 169C is set to the total of the correction amounts as in the time zone selection mode, there is a high possibility that the pointer 21 will move to an unintended position when the continuous correction operation is mistakenly performed. In addition, the continuous correction amount 169C can be made the same as the single correction amount 169B.
In this way, by allowing the continuous correction amount 169C to be set according to the type of display information, it is possible to provide the electronic timepiece 10 in which the display device 20 can be easily corrected at the position intended by the user.

  Further, in the present embodiment, it is possible to determine whether the single correction mode or the continuous correction mode is selected based on whether or not there are a plurality of rotation operations of the crown 50 within a predetermined time. For this reason, the user can easily select one of the modes simply by adjusting the operation of the crown 50 when correcting the display.

In the present embodiment, the continuous correction amount 169C other than the time zone selection mode is set to the same correction amount as the total correction amount for each display information in the display device 20. For this reason, even if the continuous correction operation is mistakenly performed, by not performing an operation for stopping the operation of the continuous correction halfway, the corresponding display device 20 makes a round and returns to the original position. For example, with the pointer 21 or the like, it goes around on the dial 11 and stops at the same position as before the operation.
Therefore, even if the continuous correction operation is mistakenly performed, there is no significant deviation from the correction position intended by the user. Therefore, the correction operation in the single correction mode is continuously performed, so that the correction position intended by the user can be easily corrected.

  Furthermore, in the present embodiment, the continuous correction amount 169C is set to the same correction amount as the single correction amount 169B for the display of the time zone that does not become a value that makes a round at regular intervals as the display information. Even in such a case, since the movement is limited to a single correction amount, it is possible to prevent the display means from going too far over the intended correction position, thereby improving the correction operability.

[Second Embodiment]
21 to 24 show a second embodiment of the present invention.
The electronic timepiece 10A of the present embodiment differs from the electronic timepiece 10 of the first embodiment described above in that there is no chronograph function and there is a day of the week display.
However, the basic configuration other than the display device 20, the input device 69, and the control device 150 related to the above-described differences is the same as that of the electronic timepiece 10 of the first embodiment described above, and the same components are denoted by the same reference numerals. In addition, overlapping explanation is omitted.

In FIG. 22A, an electronic timepiece 10A of the present embodiment includes hands 21, 22, 23, 81 and a calendar wheel 16 as a display device 20A. The hands 21, 22, and 23 respectively display the current time seconds, minutes, and hours that are display items. The hands 81 display the day of the week in this embodiment. The calendar car 16 displays the date.
In the electronic timepiece 10A, the input device 69 includes a crown 50 as an operation means, an A button 61A, and a B button 62A.

FIG. 21 shows display correction data in the present embodiment. Similar to the first embodiment described above, the display correction data is stored in the display correction data storage unit 169 (see FIG. 5).
Of the modes set in the display correction mode 169A, the “time zone selection mode”, “current time / second correction mode”, “current time / hour correction mode”, and “date correction mode” are the same as those in the first embodiment. It is the same. However, the activation button operation in the “date correction mode” is changed to “AB button 6 seconds or more”, and subsequently, “day correction mode” that can be shifted by the A button is set. This “day of the week correction mode” is for correcting the day of the week display by the hands 81 of the display device 20A.

The display correction of the date and day of the week is performed in the following procedure.
In FIG. 22B, the crown 50 is pulled one step, and both the A button 61A and the B button 62A are continuously pressed for 6 seconds or more. As a result, the control device of the electronic timepiece 10A enters the “date correction mode”.
In the display correction data of FIG. 21, the “date correction mode” is selected in the display correction mode 169A, the single correction amount 169B is set to “1”, and the continuous correction amount 169C is set to “31”.

  In this state, as shown in FIG. 23A, when the crown 50 is operated once (to the right) (for one click), the electronic timepiece 10A executes the correction process in the single correction mode in the forward rotation direction. As a result, the calendar wheel 16 moves in the forward direction by the correction amount “1”.

On the other hand, as shown in FIG. 23B, when the crown 50 is operated to “left” twice or more (two clicks or more), the electronic timepiece 10A executes the correction process in the continuous correction mode in the reverse rotation direction. In this case, the calendar wheel 16 is fast-forwarded in the reverse rotation direction, and moves to the correction amount “31”, that is, to the position where it makes one rotation. If the crown 50 is operated during the movement, the fast-forwarding of the calendar wheel 16 is stopped. By further performing a simple correction operation from this stop position, the calendar wheel 16 moves to the expected display position.
When the crown 50 is continuously corrected in the right direction, the calendar wheel 16 is fast-forwarded in the forward rotation direction, and when the crown 50 is single-corrected in the left direction, the calendar wheel 16 is corrected in the reverse direction by the correction amount “1”. "And move back one day.

As described above, when the calendar wheel 16 can be corrected to the intended display position, the A button 61A is pressed as shown in FIG. As a result, the electronic timepiece 10A shifts to the “day correction mode”.
In the display correction data of FIG. 21, the “day correction mode” is selected in the display correction mode 169A, the single correction amount 169B is set to “1”, and the continuous correction amount 169C is set to “1”.

  Here, the total correction amount in the “day correction mode” is normally “7”, and the continuous correction amount 169C may be “7”. However, when the total number of corrections is small (for example, less than 10), even if the continuous correction operation is executed, the entire display returns to the original display position in a very short time, and the stop operation on the way is difficult. For example, it is difficult to obtain the benefits of continuous correction operations. Therefore, in this embodiment, the continuous correction amount 169C in the “day of the week correction mode” is set to “1”, which is the same as the single correction amount 169B.

  In this state, as shown in FIG. 24A, when the crown 50 is operated once (to the right) (for one click), the electronic timepiece 10A executes the correction process in the single correction mode in the forward rotation direction. As a result, the pointer 81 moves by the correction amount “1” in the forward rotation direction.

On the other hand, as shown in FIG. 24B, when the crown 50 is operated to “left” at least twice (two clicks or more), the electronic timepiece 10A executes the correction process in the continuous correction mode in the reverse rotation direction. As a result, the pointer 81 is fast-forwarded in the reverse direction, but the continuous correction amount 169C is “1”, and the pointer 81 moves in the reverse direction by the correction amount “1”. Therefore, the operation is the same as the single correction operation in the reverse direction.
Even when the crown 50 is continuously corrected in the right direction, the pointer 81 moves by the correction amount “1” in the forward rotation direction. When the crown 50 is single-corrected in the left direction, the pointer 81 moves by the correction amount “1” in the reverse direction.

When the display positions of the calendar wheel 16 and the hands 81 can be corrected as described above, the crown 50 is returned to the normal position (0 stage) as shown in FIG.
Thereby, the normal operation of the hands 21, 22, and 23 indicating the current time is resumed.

According to the present embodiment as described above, in the date correction mode, the user can switch and execute a single correction operation and a continuous correction operation, and the same effects as those of the first embodiment described above can be obtained.
Furthermore, in the present embodiment, the continuous correction amount 169C in the “day of the week correction mode” is set to “1”, which is the same as the single correction amount 169B. It is possible to avoid inconveniences such as returning to the position and making stopping operation in the middle difficult.

[Other Embodiments]
In each correction mode (except for the time zone selection mode) of the first embodiment described above, the total correction amount (a numerical value of 10 or more) of each display item is set as the continuous correction amount 169C (see FIG. 7), and the normal rotation It was possible to make one rotation in the direction (forward direction) or one rotation in the reverse direction (reverse direction). However, in the present invention, embodiments with different settings may be used.

For example, the continuous correction amount 169C may be the same as the single correction amount 169B for display information that can only be corrected in either the forward direction or the reverse direction.
For example, when a thick pointer member is used as the pointer 23 for displaying the current time in the first embodiment, the hour and minute hand motor 142 may be limited in specifications (such as a clock operating voltage). In some cases, the rotation direction of 23 is unidirectional (only the forward rotation direction). In such a one-way display information correction operation, if the continuous correction amount 169C is large, the correction position intended by the user may be passed.

On the other hand, if the continuous correction amount 169C is the same as the single correction amount 169B, the correction amount is the same as the single correction operation even if the continuous correction operation is mistakenly performed. There is no deviation, and it is easy to recover erroneous operations.
When the display information is information that can be corrected only in the forward rotation direction, when the crown 50 is rotated in the reverse rotation direction, the rotation operation is invalidated and the display device 20 to be corrected may not be moved.

In the second embodiment described above, in the day correction mode, when the total number “7” of display information correction amounts is equal to or less than a preset reference value (for example, less than 10), the continuous correction amount 169C is changed to the single correction amount 169B. And the same.
On the other hand, considering not the total number of corrections but the required time for the display information to make a round by correction, the same processing is performed when the required time is equal to or shorter than a preset time (less than the round time). May be.

Even in such an embodiment, even if the continuous correction operation is executed, it is possible to avoid inconveniences such as one round, that is, returning to the original display position in a very short time, and it is difficult to stop the operation in the middle. .
FIG. 25 shows an example of the time required for such display information to make a round by correction.

In FIG. 25, the number of steps indicates the total number of correction amounts for each correction target.
Here, when looking at the pointers to be corrected and the time taken for the date wheel to go around, items marked with “*”, that is, “second hand” (pointer 81 in the first embodiment), “chronograph second hand” (Direction 21), “chronograph minute hand” (the same pointer 71), “chronograph hour hand” (the same hand 91) during normal rotation is 4 seconds or less. Among these, other than the “chronograph second hand” (the pointer 21), it is further 2 seconds or less.

Therefore, it is difficult to stop the display information that goes around in such a short time in the middle of the continuous correction operation, and if the continuous correction amount is the total number of correction amounts as in the first embodiment. Instead, as described in the column of the other embodiment of FIG. 25, the same “1” as the single correction amount may be used.
However, the “chronograph second hand” takes about 3 seconds or more to make a round, and the number of steps is as many as “300”. For this reason, the continuous correction amount of the “second hand”, “chronograph minute hand”, and “chronograph hour hand” is set to “1”, which is the same as the single correction amount, and the continuous correction amount of the “chronograph second hand” is the same as in the first embodiment. It is good also as "300".
As described above, when setting the continuous correction amount, it is desirable to set it appropriately in consideration of the user's operational feeling in consideration of the preconditions (drive frequency, number of steps, etc.) for each display item such as a guideline. .

In addition, the present invention is not limited to the above-described embodiments, and modifications and the like within a scope that can achieve the object of the present invention are included in the present invention.
The continuous correction operation is not limited to the above embodiment, and a specific rotation operation of the crown 50 or an operation of adding a button operation to the rotation operation of the crown 50 may be a continuous correction operation. For example, the continuous correction operation may be performed when the crown 50 is rotated forward, reverse, and forward within a predetermined time.
Further, the continuous correction amount is not limited to the total number of correction amounts of the display information or the same number as the single correction amount, and may be set to, for example, half the total number of correction amounts.
Furthermore, when the drive mechanism can only correct in one direction, the continuous correction amount may be set to the total number of correction amounts of the display information or a half of the total number.
