In so-called analog electronic clocks, it has been proposed to correct the position of the time hand by receiving an accurate time by electrical communication to adjust the time.

For example, in Patent Document 1 below, a comparison result of a time adjustment instruction device for transmitting reference time data and instruction time data indicated by a pointer of a pointer-type clock to a pointer-type clock and received reference time data and instruction time data is provided. Based on this, a time adjustment system including a pointer type clock that corrects the instruction of the pointer to the reference time data is described.

Japanese Patent No. 4200835

The analog electronic clock drives the time hand by electric power such as a stepping motor. Therefore, if the rotation position of the time hand at a certain time is known, the position of the time hand can be known by counting the amount of rotation of the time hand driven.

Here, consider a case where the time of the analog electronic clock is adjusted by the user's operation. In an analog electronic watch, a method of electronically performing time adjustment by a user's operation-that is, a rotation correction amount of the time hand received by an operation of a crown, a push button, etc. is once accepted as an electric command value, and such a command is given. A method of aligning the time hand by driving electrical power based on the value-and a method of mechanically-that is, the train wheel that drives the time hand is mechanically engaged with the winding stem to make the crown There are two methods of directly rotating the time hand to adjust the position while being separated from the electrical power by turning it. In the former, the amount of rotation of the time hand can be tracked electronically or electrically. , The position of the time hand is not lost, but in the latter case, the current position of the time hand is lost after the time adjustment operation because the amount of rotation by the user's operation is unknown.

When the time adjustment operation depends only on the user's operation, the user must operate at the right time while observing the accurate time shown on the clock prepared separately, and there is an error of about 1 second. It is difficult to set the time accurately because it is unavoidable. Therefore, in recent years, even in analog electronic watches, attempts have been made to receive time information from mobile terminals such as so-called smartphones to perform accurate time adjustment, but the rotation position of the time hand is known for such time adjustment. It is premised that there is, and it cannot be applied to the above-mentioned analog electronic clock in which the time is set mechanically by the operation of the user. It is considered that the invention described in the above-mentioned Cited Document 1 may be applicable to an analog electronic clock of this type, but the position of the time hand that changes from moment to moment of the analog electronic clock being driven is accurate. It is hard to say that it can be easily used by the user because it needs to be read by the user and a dedicated time adjustment device is required.

The present invention has been made in view of such circumstances, and an object of the present invention is a computer and a time adjustment system capable of accurately adjusting the time even when the position of the time hand is unknown in an analog electronic clock. Is to provide.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view showing an example of the appearance of the analog electronic wristwatch 1 according to the embodiment of the present invention. The analog electronic wristwatch 1 according to the present embodiment has the appearance of a general analog clock, and one or more time hands, here, the hour hand 22, the minute hand 23, and the second hand 21 are electrically powered, here by a stepping motor. It is driven to rotate and displays the time. The time hand is an analog display member for pointing to some time, and a typical one is a pointer, but as a special one, a rotating disk, a retrograde, or the like can be included in the time hand. In the present embodiment, the hour hand 22, the minute hand 23, and the second hand 21, which are three time hands, are interlocked with each other by a train wheel, and all three time hands are driven by one stepping motor. .. The drive state in which the time hand dynamically displays the current time, which changes from moment to moment, is referred to as normal drive.

The crown 2 is an operating member that adjusts the time hand position-that is, time adjustment-by the operation. The operation method of the crown 2 is the same as that of a general analog wristwatch. The crown 2 is pulled out and rotated to manually rotate the time hand, and when the desired position is reached, the crown 2 is pushed in. Is. In the present embodiment, by pulling out the crown 2, the train wheel that drives the hour hand 22 and the minute hand 23 and the winding stem to which the crown 2 is attached are mechanically engaged, and when the crown 2 is turned, it is hung. The hour hand 22 and the minute hand 23 are designed to rotate in conjunction with each other. At this time, the power train between the hour hand 22 and the minute hand 23 and the stepping motor is disconnected. On the other hand, the second hand 21 does not engage with the winding stem and does not rotate depending on the operation of the crown 2. At this time, since the second hand 21 remains engaged with the stepping motor, if the stepping motor rotates, the second hand 21 also rotates in conjunction with it. However, in the analog electronic watch 1, the crown 2 is pulled out. In this state, the normal drive is stopped and the rotation of the stepping motor is stopped, so that the second hand 21 is stopped at the same position.

Further, the analog electronic wristwatch 1 has a function of performing short-range wireless communication with the mobile terminal 30 which is a computer. The communication circuit and antenna for short-range wireless communication are housed in the body, which is the exterior (watch case). The standard for short-range wireless communication is not particularly limited, and may be any known standard. Further, the analog electronic wristwatch 1 may have an appropriate design as needed. For example, it may have a pointer other than the time hand illustrated here, a date, a day of the week display, a digital display, or other display member. Further, the design such as the arrangement of the dial 10 and the time hand is an example, and may be any design. Further, the hour hand 22, the minute hand 23, and the second hand 21 do not all have to rotate in conjunction with each other. For example, only the hour hand 22 and the minute hand 23 are interlocked, and the second hand 21 is independently driven by a stepping motor provided separately. It may be what is done. Further, when the crown 2 is operated, it is necessary that the normal drive is stopped, but it is not always necessary that the winding stem and the time hand are mechanically engaged with each other. However, if the time hands rotate in conjunction with each other, the number of stepping motors is small, and the mechanism by which the winding stem, the hour hand 22 and the minute hand 23 are mechanically engaged is a general analog electron. It is widely used as a watch, has a simple and low-cost structure, and has the advantage of high reliability.

In the analog electronic wristwatch 1, a windshield made of a transparent material such as glass is attached to the body so as to cover the dial 10. A back cover is attached to the body on the opposite side of the windshield. Hereinafter, in the present specification, the direction in which the windshield of the electronic wristwatch 1 is arranged (the front side of the paper surface in FIG. 1) is referred to as the front side, and the direction in which the back cover is arranged (the back side of the paper surface in FIG. 1) is referred to as the back side.

FIG. 2 is a functional block diagram of the time adjustment system 100 according to the first embodiment of the present invention. The time adjustment system 100 is a system that includes a mobile terminal 30 and an analog electronic wristwatch 1 to adjust the time of the electronic wristwatch 1. In each block shown in the figure, attention is paid to the functions realized by software by a program executed on a general-purpose information processing circuit such as a processor mounted on the mobile terminal 30 and the electronic wristwatch 1. It includes things and does not necessarily require the physical configuration corresponding to each block.

In the present embodiment, the mobile terminal 30 is illustrated as a computer that communicates with the analog electronic wristwatch 1. The mobile terminal 30 is a portable computer such as a smartphone or tablet PC, and can acquire accurate time information by being connected to an external line such as the Internet. Of course, the computer is not limited to the mobile terminal 30, and may be a type that is not suitable for carrying, such as a stationary type. The mobile terminal 30 has an operation reception unit 31, a terminal communication unit 32, a reference time determination unit 33, a current time acquisition unit 34, a difference information generation unit 35, and a display unit 36. The operation reception unit 31 receives an operation for rotating the second hand 21 of the electronic wristwatch 1. As described above, in the present embodiment, in the state where the crown 2 of the analog electronic wristwatch 1 is pulled out, the second hand 21 cannot be rotated by the operation of the crown 2, while the second hand 21 remains engaged with the stepping motor. Therefore, by driving the stepping motor, the second hand 21 can be independently rotated for alignment. When the operation is accepted by the operation reception unit 31 of the mobile terminal 30, the mobile terminal 30 notifies the analog electronic wristwatch 1 of the second hand operation information, which is a command to rotate the second hand 21, as will be described later.

The terminal communication unit 32 includes a terminal transmission unit 32a and a terminal reception unit 32b, and performs wireless communication with the clock communication unit 41. Specifically, the terminal communication unit 32 and the clock communication unit 41 communicate by short-range wireless communication. The terminal transmission unit 32a transmits difference information that specifies the difference between the reference time to be pointed by the time hand 43 and the current time. The terminal receiving unit 32b receives from the analog electronic wristwatch 1 a notification indicating that the operation of the crown 2 for aligning the time hand 43 has started and a notification indicating that the operation of the crown 2 has been completed.

The reference time determination unit 33 determines the reference time to be pointed to by the time hand 43 at the end of the operation of the crown 2. The reference time determination unit 33 may determine a position where at least one time hand 43 is in the hour direction as a reference time. In the present embodiment, since the time hand 43 includes an hour hand 22 and a minute hand 23 that rotate in conjunction with each other, the reference time is the time at which the minute hand 23 points to each hourly direction, such as 0 minutes and 5 minutes per hour.・ ・, It will be one of the times in 5/55 minute increments. Further, the reference time determination unit 33 may determine a time earlier than the current time as a reference time.

The current time acquisition unit 34 acquires the current time through an external line. The current time acquisition unit 34 may acquire an accurate current time from a so-called time server, for example, through an Internet line, or may use the GPS (Global Positioning System) function of the mobile terminal 30 to obtain time difference information and daylight saving time. Information may be acquired to acquire the current time according to the current position.

The difference information generation unit 35 generates difference information that specifies the difference between the reference time pointed to by the time hand 43 at the end of the operation of the crown 2 and the current time. The difference information may include information indicating the reference time and information indicating the current time, or may include information indicating the time difference between the reference time and the current time. The information indicating the reference time may be the reference time itself, the position of the time hand 43 indicating the reference time, or any other information capable of specifying the reference time. The same applies to the information indicating the current time. The information indicating the time difference may be the time difference itself, or the difference in the position corresponding to the time difference and the number of counts on the time hand 43, that is, the stepping required to advance the time hand 43 by the amount corresponding to the time difference. It may be any information that can specify the number of steps of the motor or other time difference.

The display unit 36 displays a reference time, which is a target time for aligning the time hand 43 of the analog electronic wristwatch 1. Here, the display format of the reference time is not particularly limited, but in the present embodiment, for the user's intuitive understanding, an image in which the time hand 43 of the analog electronic wristwatch 1 points to the reference time is displayed. It has become so. The reference time is a specific time that does not change, unlike the current time that changes from moment to moment.

The analog electronic wristwatch 1 includes a clock communication unit 41, a crown 2, a time adjustment unit 42, a time hand 43, and a second hand 21.

The clock communication unit 41 includes a clock transmission unit 41a and a clock reception unit 41b, and communicates with the terminal communication unit 32 of the mobile terminal 30 by short-range wireless communication. The clock transmission unit 41a notifies the mobile terminal 30 that the operation of the crown 2 has started when the operation of the crown 2 is started, and when the operation of the crown 2 is completed, the operation of the crown 2 is completed for the mobile terminal 30. Notify that. The watch receiving unit 41b receives the difference information for specifying the difference between the reference time, which is the time indicated by the time hand 43 at the end of the operation of the crown 2, and the current time, from the mobile terminal 30.

The crown 2 is as shown in FIG. 1, and is a member operated when aligning the time hand 43. The operation of the crown 2 is started by pulling it in the 3 o'clock direction, and ends by pushing it in the 9 o'clock direction. The clock communication unit 41 notifies the mobile terminal 30 of the start and end of the operation of the crown 2.

The time adjustment unit 42 adjusts the position of the time hand 43 to the position indicating the current time based on the difference information received from the mobile terminal 30. In addition, the second hand 21 is aligned according to the command received from the mobile terminal 30.

In the present embodiment, the time hand 43 includes an hour hand 22 and a minute hand 23. Then, as described above, the hour hand 22 and the minute hand 23 rotate in conjunction with each other, and when the minute hand rotates once, the hour hand 22 rotates 1/12 in conjunction with each other. The time hand 43 is aligned by the user by turning the crown 2 to position the time hand at a position indicating the reference time, and by the time setting unit 42 by fast-forwarding the time hand 43 to automatically point the current time. It is performed in two cases of the operation of aligning with.

FIG. 3 is a flowchart showing an example of the time adjustment process executed in the time adjustment system 100 according to the embodiment of the present invention. The time adjustment process begins when the user pulls out the crown 2 of the analog electronic wristwatch 1 (S1). Further, by pulling out the crown 2, the normal drive of the time hand 43 is stopped.

When the crown 2 is pulled, the watch transmission unit 41a notifies the mobile terminal 30 that the operation of the crown 2 has started (S2). The notification is received by the terminal receiving unit 32b of the mobile terminal 30 (S3), and the time setting application is started on the mobile terminal 30. When the terminal receiving unit 32b receives the notification that the operation of the crown 2 has started, the mobile terminal 30 may display a message calling for the user to start the time adjustment application, and the user who confirmed the message may display the message. May launch a time adjustment application.

The time adjustment application displays the reference time to be pointed to by the time hand 43 of the analog electronic wristwatch 1 on the display unit 36 (S4). Further, the second hand operation information is received and the second hand operation information is transmitted to the analog electronic wristwatch 1 (S5).

FIG. 4 is a diagram showing an example of an image showing a reference time displayed on the mobile terminal 30 according to the embodiment of the present invention. The figure shows an example of a screen displayed on the display unit 36, and includes a reference time display 36a, a reference time explanation 36b, a second hand reversal button 36c, and a second hand forward rotation button 36d.

The reference time display 36a illustrates how the time hand 43 points to the reference time. Further, the reference time explanation sentence 36b is composed of the characters "The reference time is" 15:00:00 "", and explains the reference time to the user. The reference time is determined by the reference time determination unit 33 of the mobile terminal 30.

The user confirms the reference time display 36a and the reference time description 36b displayed on the display unit 36, manually rotates the crown 2, and causes the time hand 43, here, the hour hand 22 and the minute hand 23 to indicate the reference time. Align. Further, since the position of the second hand 21 cannot be adjusted by the operation of the crown 2, the user selects the second hand reverse rotation button 36c and the second hand forward rotation button 36d displayed on the display unit 36, and the analog electronic wristwatch 1 is used. The second hand 21 is rotated forward or reverse, and is aligned so as to indicate the reference time. Every time the second hand reverse rotation button 36c and the second hand forward rotation button 36d are selected, the second hand operation information is transmitted from the mobile terminal 30 to the electronic wristwatch 1, and a drive pulse is applied to the stepping motor by the time adjustment unit 42 of the electronic wristwatch 1. The second hand 21 rotates forward or reverse for one second. When the second hand reverse rotation button 36c and the second hand forward rotation button 36d are long-pressed, the second hand 21 may be continuously operated. In the case of this example, the user operates the crown 2, the second hand reversal button 36c, and the second hand forward rotation button 36d to align the second hand 21, the hour hand 22, and the minute hand 23 of the analog electronic wristwatch 1 with the positions of 15:00:00. ..

Returning to FIG. 3, when the clock receiving unit 41b of the analog electronic wristwatch 1 receives the second hand operation information from the mobile terminal 30 (S6), the time setting unit 42 aligns the second hand 21 (S7). Further, the hour hand 22 and the minute hand 23 are aligned by the operation of the crown 2 by the user (S8). After that, when the crown 2 is pushed in the 9 o'clock direction by the user and the operation of the crown 2 is completed (S9), the normal drive is restarted, and the clock transmission unit 41a operates the crown 2 with respect to the mobile terminal 30. It is notified that it has finished (S10).

When the mobile terminal 30 receives that the operation of the crown 2 is completed (S11), the current time acquisition unit 34 acquires the current time (S12). When the mobile terminal 30 is equipped with a camera, when the terminal receiving unit 32b receives a notification that the operation of the crown 2 is completed, the user is instructed to take a picture of the analog electronic wristwatch 1 from the front side by the camera. You may. Then, the image of the analog electronic wristwatch 1 taken by the camera may be analyzed to determine whether the second hand 21, the hour hand 22, and the minute hand 23 are aligned with the positions indicating the reference time. Here, if it is determined that the alignment is correct, the current time acquisition unit 34 acquires the current time, and if it is determined that the alignment is not correct, a message prompting the user to correct is displayed. The processing after S4 may be performed. After the current time is acquired by the current time acquisition unit 34, the difference information generation unit 35 generates difference information for specifying the difference between the reference time and the acquired current time (S13). The generated difference information is transmitted to the analog electronic wristwatch 1 by the terminal transmission unit 32a (S14).

The analog electronic wristwatch 1 receives the difference information by the clock receiving unit 41b (S15), and the time setting unit 42 automatically adjusts the position of the time hand 43 to the position indicating the current time based on the received difference information. (S17). In this alignment, when the received difference information is, for example, the time difference between the reference time and the current time, the count number that is the movement amount of the time hand 43 corresponding to the time difference is obtained, and the count number is equal to the count number. This can be easily performed by fast-forwarding the time hand 43. At this time, since the fast-forward is performed at the same time as the normal drive, the aligned time does not shift as the time advances during the fast-forward.

Here, it takes only a very short time from the user pushing the crown 2 in step S9 to receiving the difference information in step S15. Therefore, the time lag between the user pushing the crown 2 and the analog electronic wristwatch 1 receiving the difference information is ignored because it is considered that it has almost no effect on the time adjustment, but the step is performed on the analog electronic wristwatch 1 side. The time from when the user pushes the crown 2 in S9 until the difference information is received in step S15 is measured, and the time is added to the received difference information so that more accurate time adjustment can be performed. You may.

According to the time adjustment system 100 according to the present embodiment, even when the position of the time hand 43 is unknown from the analog electronic wristwatch, a dedicated time is used by using a general-purpose computer such as a mobile terminal 30. Accurate time adjustment can be performed without the need for a correction device.

Here, in the present embodiment, the analog electronic wristwatch 1 is of a type in which the time hand 43 is mechanically aligned by the crown 2. Therefore, when the user pulls out the crown 2, the hour hand 22 and the minute hand 23 are separated from the power train and can rotate freely, so that the position is lost from the analog electronic wristwatch 1 and becomes unknown. However, the time adjustment system 100 according to the present embodiment should not be applied only to the analog electronic wristwatch 1 of this type, and the time hand of the analog electronic wristwatch of the type that electronically adjusts the time. It can be effectively used when the position of is unknown. In such cases, for example, the function temporarily stops due to a drop in the power supply voltage or battery replacement, and the position of the time hand is lost, or the position of the time hand shifts due to an external impact, etc. Can be considered.

FIG. 5 is a diagram showing a first example (first difference information 50a) of difference information transmitted from the mobile terminal 30 according to the embodiment of the present invention. The first difference information 50a includes the reference time information 51 indicating the reference time and the current time information 52 indicating the current time. The reference time information 51 indicates that the reference time is 15:00:00. Further, the current time information indicates that the current time is 15:10:05. The analog electronic wristwatch 1 that has received the first difference information 50a aligns the time hand 43 on the premise that the time hand 43 is aligned with the position indicating the reference time by the user. In the case of this example, the analog electronic wristwatch 1 calculates the difference between the reference time and the current time based on the first difference information 50a, and fast-forwards the time hand 43 in the forward rotation direction by an angle corresponding to 10 minutes and 5 seconds. To do.

The difference information is not limited to the model shown in FIG. 5 (first difference information 50a). FIG. 6 is a diagram showing a second example (second difference information 50b) of the difference information transmitted from the mobile terminal 30 according to the embodiment of the present invention. The second difference information 50b includes time difference information 53 indicating a time difference between the reference time and the current time. The time difference information 53 indicates that the time difference between the reference time and the current time is 10 minutes and 5 seconds. The analog electronic wristwatch 1 that has received the second difference information 50b assumes that the time hand 43 is aligned with the position indicating the reference time by the user, and the position of the time hand 43 is based on the time difference information 53. Make a match. In the case of this example, the analog electronic wristwatch 1 fast-forwards the time hand 43 in the forward rotation direction by an angle corresponding to 10 minutes and 5 seconds according to the time difference information 53.

In the above-described embodiment, the time adjustment system 100 starts the time adjustment process by the operation of pulling out the crown 2 of the analog electronic wristwatch 1, but the time adjustment process is not limited to this, and other operations such as, for example, after the crown 2 is pulled out. The time adjustment process may be started by rotation or an operation of a push button or the like separately provided on the analog electronic wristwatch 1, or as described later, the time adjustment process is started by an operation on the mobile terminal 30. You may. Further, the end of the time adjustment operation, that is, the timing at which the operation end information is generated is not limited to the time when the crown 2 is pushed in, and the time adjustment operation is ended by an arbitrary operation on the analog electronic wristwatch 1 or the mobile terminal 30. It may be a thing. At this time, the normal drive of the analog electronic wristwatch 1 may be restarted from the end of the time adjustment operation.

Further, as in the example shown in FIG. 4, the mobile terminal 30 according to the present embodiment displays on the display unit 36 the time when at least one time hand 43 is positioned in the hour direction as the reference time. Normally, an hour letter is provided at the position of the dial 10 of the analog electronic wristwatch 1 in the hourly direction, which serves as a mark for alignment. Therefore, the user operates the crown 2 to align the time hand 43. It is easy to align easily and accurately. Therefore, if the reference time determination unit 33 sets the time at which at least one time hand 43 is in the hourly direction as the reference time, the user can easily and accurately set the time.

Further, the mobile terminal 30 according to the present embodiment displays a time earlier than the current time on the display unit 36 as a reference time. For example, as shown in FIG. 5, the current time is around 15:10, while the reference time is 15:00:00. When the reference time is earlier than the current time, when the time setting unit 42 aligns the time hand 43 in step S16 of FIG. 3, the fast-forwarding direction of the time hand 43 advances the indicated time, that is, forward rotation. It becomes the direction. Generally, the step motor used to drive the time hand 43 in the analog electronic watch 1 has a feature that the rotation speed in the forward rotation direction is faster than the rotation speed in the reverse rotation direction. By setting the time before the current time, the fast-forward rotation direction at the time of automatic alignment of the time hand 43 can be set to the high-speed forward rotation direction, and the time required for alignment can be shortened. The reference time determination unit 33 may determine the time before the current time, which is the closest to the current time, at which at least one time hand 43 is located in the hour direction as the reference time.

FIG. 7 is a flowchart showing a modified example of the time adjustment process executed in the time adjustment system 100 according to the embodiment of the present invention. The time adjustment process of this modification is different from the time adjustment process example shown in FIG. 3 in that the start method of the time adjustment process is different. Specifically, in this modification, the user operates the mobile terminal 30 to start the time adjustment application (or performs a predetermined operation on the time adjustment application, for example, selecting a button), so that the time adjustment is performed. The process is started, whereas the example shown in FIG. 3 is different in that the time adjustment process is started when the user pulls the crown 2 of the electronic wristwatch 1.

The time adjustment process according to this modification starts when the user operates the mobile terminal 30 to start the time adjustment application. When the time adjustment application is activated, the mobile terminal 30 transmits hand movement stop information to the analog electronic wristwatch 1 (S20). The hand movement stop information may be automatically transmitted when the user starts the time adjustment application, or may be transmitted by an explicit command from the user.

When the hand movement stop information is received by the clock receiving unit 41b of the analog electronic wristwatch 1 (S21), the normal drive is stopped by the time setting unit 42 (S22). As a result, the movement of the time hand 43 and the second hand 21 is stopped. On the other hand, the reference time is displayed on the display unit 36 of the mobile terminal 30 (S23). The time adjustment application receives the second hand operation by the user and transmits the second hand operation information to the analog electronic wristwatch 1 (S24). The reference time may be displayed and the second hand operation may be received after the hand movement stop information is transmitted, and the reference time may be displayed at the same time as the hand movement stop information is transmitted.

When the clock receiving unit 41b of the analog electronic wristwatch 1 receives the second hand operation information from the mobile terminal 30 (S25), the time adjusting unit 42 aligns the second hand 21 (S26). Further, the crown 2 is pulled in the 3 o'clock direction by the user (S27), and the hour hand 22 and the minute hand 23 are aligned by operating the crown 2 (S28). After that, when the crown 2 is pushed in the 9 o'clock direction by the user and the operation of the crown 2 is completed (S29), the clock transmission unit 41a notifies the mobile terminal 30 that the operation of the crown 2 is completed (S29). S30).

When the mobile terminal 30 receives that the operation of the crown 2 is completed (S31), the current time acquisition unit 34 acquires the current time (S32). Then, the difference information generation unit 35 generates difference information for specifying the difference between the reference time and the current time based on the determined reference time and the acquired current time (S33). The generated difference information is transmitted to the analog electronic wristwatch 1 by the terminal transmission unit 32a (S34).

The analog electronic wristwatch 1 receives the difference information by the clock receiving unit 41b (S35), and the time setting unit 42 automatically adjusts the position of the time hand 43 to the position indicating the current time based on the received difference information. To do. (S36). This alignment method may be the same as that shown in the previous example.

According to the time adjustment process according to this modification, when the short-range wireless communication between the mobile terminal 30 and the analog electronic wristwatch 1 cannot be used, such as when moving by an aircraft, or when the power of the mobile terminal 30 is not turned on, the time adjustment is performed. If this is not possible, it is possible to prevent a situation in which the analog electronic wristwatch 1 is accidentally operated and the time displayed on the analog electronic wristwatch 1 is rather deviated.

FIG. 8 is a flowchart showing a preprocessing executed in the time adjustment system 100 according to the embodiment of the present invention. The figure shows a process performed in the electronic wristwatch 1 when the communication between the electronic wristwatch 1 and the mobile terminal 30 is not always established.

This process starts with determining whether or not the crown operation information is stored (S40). Here, the crown operation information is information indicating that the crown 2 which is an operation member has been operated by the user. The timing of storing the crown operation information will be described in detail later.

When the crown operation information is not stored, it is determined whether or not the crown 2 is pulled (S41). If the crown 2 is not pulled, the preprocessing ends. When the crown 2 is pulled, it is determined whether or not the connection between the watch communication unit 41 and the mobile communication unit 32 is established (S42). Here, when it is determined that the connection has been established, information instructing the start-up of the time adjustment application is transmitted from the electronic wristwatch 1 to the mobile terminal 30 (S43). Here, the information instructing the start of the time adjustment application may be a command for automatically starting the time adjustment application, or a display command for an instruction screen prompting the user to start the time adjustment application. .. The process to be performed after that may be the process after S3 in FIG. 3 or the process after S20 in FIG. 7.

When it is determined that the connection with the mobile terminal 30 is not established, the watch communication unit 41 tries to connect with the mobile communication unit 32 (S44). After the trial, the connection state with the mobile terminal 30 is determined again (S45), and if the connection is established, the information instructing the start-up of the time adjustment application is transmitted (S43). On the other hand, when communication with the mobile terminal 30 is not established, the crown operation information is stored (S46). The electronic wristwatch 1 is provided with a detection mechanism for detecting the pulling out or rotation of the crown 2, and may automatically store the crown operation information based on the detection information from the detection mechanism, or the user can operate the operation member. The crown operation information may be stored based on the above.

Returning to the beginning of the flowchart shown in FIG. 8, when the crown operation information is stored (S40: Y), an irregular hand movement is performed to urge the user to try to connect to the electronic wristwatch 1 from the mobile terminal 30 (S47). .. The irregular hand movement may be any movement other than the normal timekeeping operation, and may be, for example, a hand movement in which the second hand 21 is rotated counterclockwise for several seconds.

After that, the connection state with the mobile terminal 30 is determined (S45), and if the connection is established, the crown operation information is reset (S49), and the information instructing the start of the time adjustment application is transmitted (S). S43). On the other hand, if communication with the mobile terminal 30 is not established, the process ends. The determination of the connection state with the mobile terminal 30 may be performed for a certain period of time after the irregular hand movement is performed.

According to this process, even when the mobile terminal 30 and the electronic wristwatch 1 cannot be connected to each other, such as when the power of the mobile terminal 30 is turned off, the user is urged to operate the mobile terminal 30 and the mobile terminal 30 is operated. The connection between the 30 and the electronic wristwatch 1 can be established, and the time adjustment process can be performed.

Although the embodiment according to the present invention has been described above, the specific configuration shown in this embodiment is shown as an example, and it is not intended to limit the technical scope of the present invention to this.

For example, in the above-described embodiment, the second hand 21 has been described as being aligned by the operation received by the operation reception unit 31 of the mobile terminal 30, but instead of this, a push button separately provided on the analog electronic wristwatch 1 or the like is used. Alignment may be performed using an operating member other than the crown 2. Alternatively, the crown 2 may be pulled out in two stages, and by further pulling out the crown 2, the second hand 21 may be aligned by the rotation of the crown 2. Further, some pointers such as the second hand 21 are provided with a mechanism for detecting the position, and only the pointer whose position can be detected is operated by the time adjustment unit 42 without requesting the adjustment by the user. Automatic alignment may be performed. An example of such a position detection mechanism is a disk with a slit (or hole) that rotates in conjunction with the second hand 21 and a photoelectric sensor that detects that the second hand 21 is in the 0 second position. Can be mentioned.
