Description

The present invention relates to an electronic clock that displays a time using a pointer.

Conventionally, there are electronic clocks capable of displaying and operating various functions in addition to displaying the time. Functions other than the time display include, for example, an alarm notification function and a setting display of the notification time, a stopwatch function, a timer function, a physical quantity measurement by various measurement sensors, a calculation and its display function, and a function acquired from an external device. Examples include a notification function based on schedule information and status information.

It is often difficult to set a separate pointer for each function in an electronic watch such as a wristwatch, which has a small display screen, or an electronic watch that has an upper limit on the number of motors (stepping motors) that operate the pointer. Therefore, conventionally, the display related to a plurality of functions is switched and performed according to a common guideline. In addition, when it is difficult to perform the pointer operation and the operation related to other functions at the same time due to the influence on the operation of the stepping motor or the power limitation, some of the pointers are operating related to the other functions. There is a technique to interrupt the pointer operation by displaying a message indicating that.

However, there is a problem that if the time is not displayed at all while the pointer used for displaying the time is used for the display related to the function other than the time display function, the user cannot know the current time during that time. .. In Patent Document 1, while receiving a radio wave (standard radio wave) for acquiring current time information from the outside, the second hand is stopped at a predetermined position indicating that the standard radio wave is being received, while the second hand is more than the second hand. A technique for continuing to display the time by other pointers such as an hour hand and a minute hand, which are infrequently operated, is disclosed.

Japanese Unexamined Patent Publication No. 2008-170459

However, in an electronic clock that displays the time using a pointer that rotates in conjunction with it, the display state is temporarily changed so that the display other than the time is performed by some pointers and the display of the time is continued by other pointers. When switching, the display other than the time is temporarily interrupted in conjunction with this update operation while the display of the time continued by another pointer is updated. Therefore, if the time display is updated uniformly and periodically, there is a problem that the user may easily have a problem in visually recognizing the display other than the time.

An object of the present invention is to provide an electronic timepiece capable of more appropriately achieving both a time display and a non-time display.

In order to achieve the above object, the present invention
The first pointer rotatably provided and
A second pointer that rotates in conjunction with the rotation of the first pointer,
A control unit that controls the rotation of the first pointer and the second pointer,
Equipped with
The control unit
At the time of executing the predetermined functional operation, the first pointer is rotated clockwise to move it to the display position corresponding to the state related to the predetermined functional operation.
If the first pointer is delayed by a predetermined first reference time or more from the current time while the first pointer indicates the display position according to the state related to the predetermined functional operation, the first guideline is described. To change the position indicated by the second pointer,
The predetermined first reference time is determined according to the angle difference between the display position and the predetermined reference position according to the state.
When the first pointer is rotated clockwise to move to the display position according to the state related to the predetermined functional operation, the first pointer has passed the predetermined reference position and the case where the first pointer has passed the predetermined reference position. The predetermined first reference time differs depending on whether or not the time is present.
It is an electronic clock characterized by this.

According to the present invention, there is an effect that the display of the time and the display other than the time can be more appropriately compatible with each other in the electronic timepiece.

Indicates the communication connection status.

FIG. 2 is a block diagram showing a functional configuration of the electronic clock 1 of the present embodiment.
The electronic clock 1 of the present embodiment has a train wheel mechanism in addition to the above-mentioned hour hand 2, minute hand 3, second hand 4, day wheel 5, small hour hand 6 and small minute hand 7 (hereinafter collectively referred to as pointers 2 to 7 and the like). 71 to 73, stepping motors 81 to 83, drive circuit 51, CPU 41 (Central Processing Unit) as a control unit (processor), ROM 42 (Read Only Memory), RAM 43 (Random Access Memory), and oscillation circuit. It includes a frequency dividing circuit 45, a time measuring circuit 46 as a time measuring unit, a notification operation unit 47, an operation receiving unit 48, a wireless communication unit 49, an antenna 50, a power supply unit 52, and the like.

The CPU 41 performs various arithmetic processes and collectively controls the overall operation of the electronic clock 1. Further, the CPU 41 outputs a control signal for moving the pointers 2 to 7 to the drive circuit 51, respectively.

The ROM 42 stores various programs executed by the CPU 41 and initial setting data used in the various programs. These programs and initial setting data are read out by the CPU 41 at the time of starting the electronic clock 1 or at any time as needed, and are executed and used.
The ROM 42 may be various non-volatile memories such as a flash memory that is partially or completely rewritable or an EEPROM (Electrically Erasable and Programmable Read Only Memory).
The RAM 43 provides a working memory space to the CPU 41 and stores temporary data. The temporary data includes connection destination information 43a for communication by the wireless communication unit 49, setting information 43b acquired from the connection destination, and the like.

FIG. 3 is a chart showing an example of setting information 43b that can be set in the electronic clock 1 of the present embodiment.
Here, alarm notification, local time setting, schedule notification, and communication setting can be set and stored.
The alarm notification setting includes information on whether or not an alarm notification operation is performed at a set time and information on the alarm notification setting time. When the alarm notification operation is set to on, the alarm notification operation is performed at the set time.

The local time setting is the setting of the local time (basic clock) of the current location displayed using the pointers 2 to 5, and the setting of the local time (world clock) of any region of the world displayed using the pointers 6 and 7. And, including.
The setting contents include information on the time zones of the basic clock and the world clock, whether or not daylight saving time is implemented, the implementation period when it is implemented, and the shift time at the time of implementation. The time displayed as the world clock is not particularly limited, but for example, the time difference between the basic clock and the world clock is calculated in advance based on these local time settings, and the time is set to the counted basic clock time. On the other hand, it is calculated by applying this time difference.

The schedule notification setting includes a notification on / off setting and a notification type setting for performing a predetermined notification operation at a predetermined time on a set day. As the notification date, for example, a date on which the notification operation is to be performed can be simply set. Further, as the notification type, it is possible to determine the types of various notification operations that can be executed by the notification operation unit 47 and the pointers 2 to 7.

The communication setting includes setting the timing of making a communication connection with the electronic device in order to automatically acquire the date and time information for adjusting the date and time of the electronic clock 1 from the external electronic device. For example, when making a communication connection four times a day every six hours, the first communication connection timing can be set at 1:00 am. Alternatively, the communication connection at midnight can be omitted and set at 7:00, 12:00, 17:00, 23:00, etc., respectively. Further, the acquisition timing of the setting information can be set at the same time as the communication connection at 7 o'clock related to the acquisition of the date and time information, for example. Alternatively, the acquisition timing of the setting information may be set separately from the acquisition timing of the date and time information, for example, at 9:30.

The power supply unit 52 supplies electric power necessary for operation to each unit of the CPU 41 and the electronic clock 1. The power supply unit 52 is not particularly limited, but for example, it holds a solar panel and a secondary battery in combination as a battery, and enables long-term and stable power supply from the battery.

The oscillation circuit 44 generates a predetermined frequency signal and outputs it to the frequency dividing circuit 45. The frequency dividing circuit 45 divides the frequency signal input from the oscillation circuit 44, generates a signal of the frequency set by the control signal from the CPU 41, and outputs the signal to the CPU 41. Further, the frequency dividing circuit 45 generates a predetermined frequency signal (for example, a 1-second signal) and outputs it to the time measuring circuit 46.

The timekeeping circuit 46 is a counter that counts the input frequency signal and counts the date and time. This counter is not limited to the counter circuit as a hardware configuration, and may be a RAM or the like that stores the date and time counted by software by the CPU 41. When the time display operation by the pointers 2 to 7 or a part thereof is executed, these pointers 2 to 7 are moved to the display position of the time corresponding to the current time counted by the clock circuit 46.

The notification operation unit 47 performs a predetermined notification operation according to the control signal from the CPU 41.
The notification operation unit 47 is not particularly limited, but includes, for example, a beep sound generation unit having a piezoelectric element that generates a beep sound, a vibration generation unit having a weighted motor that generates vibration, and the like.

The operation reception unit 48 receives an operation from the outside by the user, converts it into an electric signal, and outputs it to the CPU 41 as an input signal. The operation receiving unit 48 includes the above-mentioned push button switches B2 and B3 crown C1. The CPU 41 switches the display contents by the pointers 2 to 7, for example, the basic clock display by the pointers 2 to 5 and the pointers 6 and 7 according to the operation contents from the outside to the push button switches B2, B3 and the crown C1. The world clock display can be replaced with the world clock display by, the alarm notification setting time can be displayed by the pointers 6 and 7, and the daylight saving time implementation of the basic clock and the world clock can be switched. You can make changes.

The wireless communication unit 49 relates to proximity wireless communication with an external electronic device via an antenna 50 based on the control of the CPU 41, and here, transmission and reception of predetermined information by Bluetooth (registered trademark: Bluetooth). Do the action. The wireless communication unit 49 of the present embodiment may be configured such that the power supply is controlled independently of the other parts of the electronic clock 1 and the power supply is not received during the period when the wireless communication unit 49 is not operated. .. Further, a communication connection is made between the electronic clock 1 and an external electronic device only when information is transmitted / received or when the user manually performs an input operation related to a connection command, and a communication connection is usually made. Has been released. Therefore, the duration of the communication connection state by the wireless communication unit 49 in the electronic clock 1 of the present embodiment is not limited to the configuration upper limit of the electronic clock 1, but is usually assumed to be about several minutes or less.

The stepping motors 81 to 83 are step-driven based on the voltage waveform of the drive pulse input from the drive circuit 51, for example, the rotor is rotated 180 degrees with respect to the stator, and the corresponding pointers 2 to 7 are rotated forward. It is possible to rotate and move by a predetermined angle in the direction or the reverse direction. The stepping motors 81 to 83 of the present embodiment are capable of fast-forward rotation of up to 80 pps (Pulse per Second) in the forward rotation direction (direction in which the time advances), and are capable of fast-forward rotation in the reverse rotation direction (direction opposite to the forward rotation direction). ), Fast forward rotation of up to 32 pps is possible.

The train wheel mechanism 71 to 73 is a gear train that transmits the rotational operation of the stepping motors 81 to 83 to the corresponding pointers 2 to 7, respectively, to rotate the stepping motors 81 to 83 by a predetermined angle. The train wheel mechanism 71 transmits the rotational operation of the stepping motor 81 to the second hand 4 and the minute hand 3. The train wheel mechanism 72 transmits the rotational operation of the stepping motor 82 to the hour hand 2 and the date wheel 5. The train wheel mechanism 73 transmits the rotational operation of the stepping motor 83 to the hour hand 6 and the minute hand 7.

In the electronic clock 1 of the present embodiment, the second hand 4 rotates by 6 degrees (the angle of rotation of the first pointer) every time the stepping motor 81 is driven by one step, and the minute hand 3 rotates in conjunction with this by 6 degrees (the angle of rotation of the first pointer). It rotates by 1/10 degree (rotation angle of the second pointer) smaller than the rotation angle of 4. Therefore, when the time display operation is executed, the second hand 4 is moved every second and rotates 360 degrees in 1 minute, and the minute hand 3 rotates 6 degrees in 1 minute and 360 degrees in 1 hour. ..
Further, each time the stepping motor 82 is driven by one step, the hour hand 2 rotates by 0.5 degrees. Every time the hour hand 2 makes two rounds, the date wheel 5 rotates by 3/62 degrees in conjunction with the rotation of the hour hand 2 from the 10 o'clock position to the 2 o'clock position. Therefore, the hour hand 2 is moved every minute when the time display operation is executed, rotates 30 degrees in 1 hour, and rotates 360 degrees in 12 hours. Along with this, the date wheel 5 moves by 240 steps 360/31 degrees in 4 hours from 22:00 to 2:00, that is, by rotating the angle according to the interval of the date sign.
Further, each time the stepping motor 83 is driven by one step, the minute hand 7 rotates by 6 degrees, and in conjunction with this, the minute hand 6 rotates by 0.5 degrees. Therefore, when the minute hand 7 is executed (including the world clock display), the minute hand 7 is moved every minute and rotates 360 degrees in one hour, and the minute hand 6 is moved by 30 degrees in one hour. It rotates 360 degrees in 12 hours.

The drive circuit 51 outputs drive pulses to the stepping motors 81 to 83 based on the control signal input from the CPU 41. When a control signal for operating a plurality of stepping motors 81 to 83 is acquired from the CPU 41 at the same time, the drive circuit 51 appropriately adjusts the timing, and adjusts the peak voltage of the drive pulse and the pulse width of the peak voltage output. It can be adjusted.

Next, the functional operation in the electronic clock 1 of the present embodiment will be described.
In the electronic clock 1 of the present embodiment, it is set by the corresponding application program (hereinafter referred to as an application) in the communication connection destination electronic device (here, mainly a smartphone is assumed) set as the connection destination information 43a. The setting information related to the set operation setting is received and acquired and held as the setting information 43b. Then, at the timing set in the setting information 43b, the operation set in association with the timing is performed by a part or all of the notification operation unit 47 and the pointers 2 to 7.

Further, in the electronic clock 1, similarly, the communication setting set by using the application in the electronic device of the communication connection destination is acquired and held as the setting information 43b. Then, a communication connection is made with the electronic device at the acquisition timing of the date and time information defined in this communication setting, and the date and time information acquisition operation for acquiring the date and time information from the electronic device is performed. Further, in the electronic clock 1, a date / time correction operation is performed in which the date / time of the timekeeping circuit 46 is corrected according to the date / time information acquired in this date / time information acquisition operation, and the time displayed by the pointer is corrected.

Further, there is a terminal search operation as a function operation separate from the function operation set as the setting information 43b and the date / time correction operation.
In the terminal search operation (also referred to as Find Me operation), a communication connection is made with an electronic device preset as a communication connection destination of the electronic clock 1 in the connection destination information 43a, and a predetermined notification operation is performed to the electronic device, here. , Notifies the location of the electronic device to the user, mainly by outputting voice.

In the electronic clock 1, when a communication connection with an electronic device by short-range wireless communication is performed according to a function operation different from these time display operations or its setting, the state in which the communication connection is attempted or the communication connection is performed. A communication connection status notification operation indicating that the status is established is performed. Here, this notification operation is performed by instructing the character signs "R", "F", and "C" (display positions according to the state) shown in FIG. 1 by the second hand 4. The character sign "R" is instructed between the reception of the instruction for the communication connection operation and the establishment of the connection. The character sign "F" is instructed between the start of the communication connection related to the terminal search operation and the establishment of the connection. The character sign "C" is instructed between the establishment of the communication connection and the disconnection of the communication connection. That is, here, the character signs corresponding to two or three (two or more predetermined number) states are sequentially instructed between the reception of the instruction for the communication connection operation and the cancellation of the communication connection.

FIG. 4 is a chart showing the types of communication connections in the electronic clock 1 of the present embodiment.
In this electronic clock 1, the above-mentioned date and time information acquisition operation, setting information acquisition operation, terminal search operation, and manual connection operation can be executed.
In the date / time information acquisition operation, processing is automatically started at a preset timing to establish a communication connection, and the communication connection is canceled as soon as the date / time information is acquired. The date and time information can be acquired manually, and can also be acquired when another type of communication connection is made.

In the setting information acquisition operation, the process is automatically started at a preset timing to establish the communication connection, and the communication connection is canceled as soon as the setting information is acquired and the setting information 43b is updated. It should be noted that this setting information acquisition operation may be performed together with the date / time information acquisition operation. For example, in one of the four date / time information acquisition operations, both the date / time information and the setting information are acquired. Is also good. Further, the acquisition of the setting information may be performed by transmitting from the electronic device based on the operation of the user in the electronic device when the manual connection operation is performed.

The terminal search operation is started by the user pressing a predetermined push button switch, here, the push button switch B3 continuously for a predetermined time (3 seconds) to establish a communication connection, and the communication connected electronic device. To perform a predetermined notification operation. The communication connection with the electronic device is automatically performed after a predetermined time after the communication connection is established, for example, 30 seconds later, or when the user manually cancels the communication connection with the electronic clock 1 or the electronic device. Will be released.

The manual connection operation is started by the user continuously pressing the push button switch B3 for a predetermined time (1.5 seconds or more and less than 3 seconds) to establish a communication connection. When the electronic clock 1 and the electronic device are connected by communication by the manual connection operation, the electronic clock 1 automatically performs the date and time information acquisition operation. In addition, various operations can be performed by causing the user to perform an executable command using a predetermined application installed in the electronic device. Examples of the instructions that can be executed by the application include transmission of the above-mentioned setting information, acquisition of the battery state of the electronic clock 1, correction setting of the pointer position of the electronic clock 1, and the like. The communication connection in this case is maintained until the user cancels the communication connection with the electronic clock 1 or the electronic device. If there is no communication from the electronic clock 1 or the electronic device for a predetermined time or more, the communication connection may be automatically disconnected.

In the electronic clock 1, the hour and minute of the current time can be displayed by the hour hand 2 and the minute hand 3 even while the second hand 4 is displaying the communication state. However, in this electronic clock 1, since the second hand 4 and the minute hand 3 rotate in conjunction with each other due to the operation of the stepping motor 81, it is necessary to operate the second hand 4 at the same time in order to move the minute hand 3. In the electronic clock 1, when the current time becomes 0 seconds of each hour and minute (here, the 0 second position is set as a predetermined reference position) and the minute value (minute value) of the time changes during communication connection. In order not to change the position indicated by the second hand 4, the second hand 4 is moved once orbit (circumferential operation) to advance the minute and second values (minute and second values) indicated by the minute hand 3 by one minute.
That is, when the character sign "C" is instructed, the time corresponding to the position indicated by the minute hand 3 (corresponding to 28 seconds for each minute) is 32 seconds from the current time (first reference time, 0 seconds). (Corresponding to 192 degrees due to the difference in angle from the position) The time corresponding to the position indicated by the minute hand 3 (corresponding to 18 seconds for each minute) when delayed or when the character sign "R" is indicated. If it is 42 seconds behind the current time (corresponding to 252 degrees due to the angle difference from the 0 second position), the indicated position of the minute hand 3 is changed.

In the electronic clock 1 of the present embodiment, as described above, the duration of the communication connection state is expected to be about several minutes at the longest, but the duration of the communication connection state is undefined depending on the type of connection operation, and in particular. , When the communication connection is established by the manual connection operation, it is not possible to know the time until the connection is released in advance and optimize the processing. Therefore, in the electronic clock 1, when the second hand 4 is moved from the position of the second value (second value) of the time to the position of the character sign indicating the reception state, it is always fast-forwarded clockwise in the forward rotation direction. As a result, if the current time counted by the timekeeping circuit 46 is originally correct, the hour hand 2 and the minute hand 3 are displayed with a substantially accurate time with a progress of less than 1 minute, and from the reception of the instruction for the communication connection operation to the cancellation of the communication connection. If the required time is less than 42 seconds, the lap fast-forward operation of the second hand 4 is not performed in the middle, and if the required time is less than 1 minute 42 seconds, the lap fast-forward operation of the second hand 4 is required in the middle. Will be reduced.

Similarly, when changing the instruction position of the second hand 4 from the character sign "R" to another character sign "F" or "C", or when changing the instruction position of the second hand 4 from the character sign "F" to the character sign "C". Even when changing, the pointer is always rotated in the forward rotation direction so that the time displayed by the minute hand 3 is not delayed as much as possible from the current time.
Since the duration indicating the character sign "R" is usually assumed to be several seconds or less, the time is assumed to be sufficiently shorter than the time display accuracy (second reference time) or less. May be set so that the lap fast-forward operation of the second hand 4 is not performed from the beginning. The second reference time is appropriately determined and may be shorter or longer than the above-mentioned first reference time.

5 and 6 are diagrams showing display examples of pointers 2 to 4 during a communication connection operation.
Here, the display of the guidelines 5 to 7 is omitted.

As shown in FIG. 5A, when the communication connection command is received at 10:05:10, the second hand 4 moves to the 18-second position (the position of the character sign “R”) in the forward rotation. , 10:05:18 is displayed as shown in FIG. 5 (b). When the communication connection is established at 10:05:14, the second hand 4 moves in the normal direction to the 28-second position (position of the character sign "C"), and as shown in FIG. 5 (c), it moves to 10 o'clock. Display 5 minutes and 28 seconds. After that, when 46 seconds have passed while the communication connection is maintained and the current time reaches 10:06:00, the second hand 4 is fast-forwarded in a forward rotation around the circumference, and at 10:06 as shown in FIG. 5 (d). Display 28 seconds.

On the other hand, as shown in FIG. 6A, when the communication connection command is received at 10:05:24, the second hand 4 moves to the 18-second position (position of the character sign “R”) in the forward rotation. As a result, as shown in FIG. 6B, 10:06:18 is displayed with a progress of 54 seconds. After that, when the communication connection is established at 10:05:28, the second hand 4 is moved to the 28-second position (position of the character sign "C") in the normal rotation, and as shown in FIG. 6 (c). 10:06:28 is displayed with a progress of exactly 1 minute. When 32 seconds have passed while the communication connection is maintained and the current time reaches 10:06: 0, the minute hand 3 is already at the 6-minute position, so that the second hand 4 is not rotated forward and fast-forwarded. .. Then, when another minute has passed while the communication connection is maintained and the current time reaches 10:07:00, the second hand 4 is fast-forwarded in the forward rotation for the first time, as shown in FIG. 6 (d). 10:07:28 is displayed at.

FIG. 7 is a flowchart showing a control procedure by the CPU 41 of the communication connection control process executed by the electronic clock 1 of the present embodiment.
In this communication connection control process, when the CPU 41 requires a communication connection with an electronic device in the control process related to various function operations and its setting operations, and when the user presses a predetermined push button switch B3, the communication connection is made. Triggered when an instruction is detected.

When the communication connection control process is started, the CPU 41 outputs a control signal to the drive circuit 51, fast-forwards the second hand 4 in the forward rotation direction at the fastest speed, and moves the second hand 4 to the position of the character sign "R" (step S101). .. The CPU 41 determines whether or not the communication connection control process is automatically started regardless of the manual input operation (step S102). If it is determined that the startup is automatic (“YES” in step S102), the processing of the CPU 41 proceeds to step S103.

If it is determined that it was not started automatically, that is, it was started by the user's manual input operation (“NO” in step S102), the CPU 41 sets the communication connection to the automatic disconnect mode (step S111). ), It is determined whether or not the pressing operation of the push button switch B3 by the user is completed (step S112). If it is determined that the process has been completed (“YES” in step S112), the processing of the CPU 41 proceeds to step S103.

If it is determined that the push button switch B3 has not been pressed by the user, that is, it is still continued (“NO” in step S112), the CPU 41 has 3 seconds after the push operation is started. Is determined (step S113). If it is determined that 3 seconds have not elapsed (“NO” in step S113), the CPU 41 determines whether or not 1.5 seconds have elapsed since the pressing operation was started (step S114). .. If it is determined that 1.5 seconds have not elapsed (“NO” in step S114), the processing of the CPU 41 returns to step S112.

If it is determined that 1.5 seconds have elapsed (“YES” in step S114), the CPU 41 changes the communication connection to the manual release mode. Further, the CPU 41 outputs a control signal to the drive circuit 51, and causes the second hand 4 at the position of the character sign “R” to perform a predetermined vibration operation (step S115). For example, the CPU 41 fast-forwards the second hand 4 in the forward rotation direction by 3 steps, then fast-forwards the second hand 4 in the reverse rotation direction by 6 steps, and finally fast-forwards the second hand 4 in the forward rotation direction by 3 steps. At this time, if there is play (backlash) in the train wheel mechanism 71 that transmits the rotational operation of the stepping motor 81 to the second hand 4 and the minute hand 3, the CPU 41 is operated by an extra number of steps corresponding to the play to appear. Make sure that the number of upper movement steps does not decrease, and finally that there is no play left for rotation in the forward rotation direction. Then, the process of the CPU 41 returns to step S112.

If it is determined in the determination process of step S113 that 3.0 seconds have passed since the push button switch B3 was pressed (“YES” in step S113), the CPU 41 has set the communication connection in step S115. The manual release mode is further shifted to the terminal search mode, that is, a mode in which both automatic release and manual release are possible, a control signal is output to the drive circuit 51, and the second hand 4 is set to the position of the character sign "F". The fast forward movement is performed (step S116). Then, the process of the CPU 41 proceeds to step S103.

When the process of steps S102, S112, and S116 shifts to the process of step S103, the CPU 41 refers to the connection destination information 43a and acquires the information of the connection destination electronic device by Bluetooth (step S103). The CPU 41 outputs a communication connection request to the electronic device for which the setting has been acquired, and performs an operation of establishing a communication connection with the electronic device (step S114). The CPU 41 determines whether or not the communication connection has been established (step S105), and if it is determined that the communication connection has not been established (“NO” in step S105), repeats the process of step S104. If the time-out time is set and the communication connection is not established for the time-out time or longer, the communication connection can be abandoned and the processing by the CPU 41 can be terminated.

When it is determined that the communication connection has been established (“YES” in step S105), the CPU 41 outputs a control signal to the drive circuit 51 and moves the second hand 4 to the position of the character sign “C” in forward rotation and fast forward. (Step S106). The CPU 41 executes the operation command every time an operation command such as setting update is input from the electronic device connected to the communication, and determines whether or not the communication connection is set to the manual release mode (step). S107).

If it is determined that the manual release mode is set (“YES” in step S107), the CPU 41 determines whether or not the input operation related to the release of the communication connection is accepted and detected (step S121). ). If it is determined that the detection has been detected (“YES” in step S121), the processing of the CPU 41 proceeds to step S142. In this case, the detected input operation may be an operation of pressing a predetermined push button switch in the electronic clock 1, or may be an operation of disconnecting the connection in the connected electronic device.

When it is determined that the input operation related to the disconnection of the communication connection has not been detected (“NO” in step S121), the CPU 41 acquires the current time, the current time is 0 seconds per minute, and the current time is 0 seconds. It is determined whether or not the minute value indicated by the position of the minute hand 3 and the minute value of the current time deviate from each other (step S122). If it is not 0 seconds, or if it is determined that the position of the minute hand 3 and the minute value of the current time do not deviate (match) (“NO” in step S122), the processing of the CPU 41 is performed in step S121. return. If it is 0 seconds and it is determined that the position of the minute hand 3 and the minute value of the current time deviate from each other (“YES” in step S122), the CPU 41 outputs a control signal to the drive circuit 51. The position of the minute hand 3 is advanced by 1 minute by advancing the second hand 4 in the forward rotation direction for one round at the fastest speed (step S123). Then, the process of the CPU 41 returns to step S121.

When it is determined in the determination process of step S107 that the communication connection is not in the manual release mode (“NO” in step S107), the CPU 41 determines whether or not the communication connection is in the terminal search mode (step S108). .. When it is determined that the terminal search mode is set (“YES” in step S108), the CPU 41 transmits an instruction to cause the electronic device to perform a predetermined notification operation via the wireless communication unit 49 (step S131). The CPU 41 determines whether 30 seconds have passed since the communication connection was established, or whether the input operation related to the disconnection of the communication connection is detected (step S132). If it is determined that any of them has been detected (“YES” in step S132), the processing of the CPU 41 proceeds to step S142. In this case as well, the detected input operation may be an operation of pressing a predetermined push button switch in the electronic clock 1, or may be an operation of disconnecting the connection in the connected electronic device.

If it is determined that 30 seconds have not passed since the communication connection was established and the input operation related to the disconnection of the communication connection has not been detected (“NO” in step S132), the CPU 41 is currently The time is acquired, and it is determined whether or not the current time is 0 seconds per minute and the minute value indicated by the position of the minute hand 3 and the minute value of the current time deviate from each other (step S133). If it is not 0 seconds, or if it is determined that the position of the minute hand 3 and the minute value of the current time do not deviate (match) (“NO” in step S133), the processing of the CPU 41 is performed in step S132. return. If it is 0 seconds and it is determined that the position of the minute hand 3 and the minute value of the current time deviate from each other (“YES” in step S133), the CPU 41 outputs a control signal to the drive circuit 51. The position of the minute hand 3 is advanced by 1 minute by advancing the second hand 4 in the forward rotation direction for one round at the fastest speed (step S134). Then, the process of the CPU 41 returns to step S132.

If it is determined in the determination process of step S108 that the mode is not the terminal search mode (“NO” in step S108), the CPU 41 acquires necessary information according to the operation mode (step S141). In this case, the operation of the electronic clock 1 is a time information acquisition operation or a setting information acquisition operation for acquiring predetermined setting information 43b, both of which are automatic release modes in which the communication connection is automatically released. Then, the process of the CPU 41 proceeds to step S142.

When the process shifts from any of the processes of steps S121, S132, and S141 to the process of step S142, the CPU 41 transmits a request for disconnecting the communication connection to the electronic device communicated and connected via the wireless communication unit 49. , Cancel the communication connection (step S142). The CPU 41 acquires the current time, outputs a control signal to the drive circuit 51, and moves the pointers 2 to 7 to positions corresponding to the current time (step S143). Then, the CPU 41 ends the communication connection control process.

FIG. 8 is a diagram showing an example of changes in the indicated states of the minute hand and the second hand at the time of communication connection for each type of communication connection.

As shown in FIG. 8A, at the time of automatic communication connection related to the date / time information acquisition operation and the setting information acquisition operation, the second hand 4 rotates in the normal direction at the timing t10 for starting the communication connection, and the position of the character sign “R”. Is moved to (step S101). Then, in this automatic connection (“YES” in step S102), the connection destination information is acquired while the second hand 4 is maintained at the position of the character sign “R” (step S103), and the communication connection with the electronic device is started. (Step S104). Then, at the timing t20 when the communication connection is established (“YES” in step S105), the second hand 4 is moved to the position of the character sign “C” by normal rotation (step S106).

It branches to "NO" in step S107, further branches to "NO" in the determination process of step S108, and the communication connection is disconnected at the timing t30 (step S141) when the acquisition of the date and time information and the setting information is completed. At the same time (step S142), the minute hand 3 and the second hand 4 are fast-forwarded to the normal current time display position (step S143). Acquisition and updating of date and time information and setting information usually ends in a short time, for example, in a few seconds or less. Therefore, in this electronic clock 1, communication is performed until the minute value of the time indicated by the minute hand 3 becomes smaller than the minute value of the current time. It is highly unlikely that the connection will be maintained, and even if the minute value of the time indicated by the minute hand 3 is smaller than the minute value of the current time, it is not expected that this situation will continue for more than a few seconds. Therefore, here, the second hand 4 is stopped at the position of the character sign "C" while the communication connection is maintained.

As shown in FIG. 8B, when the date and time information acquisition operation is manually performed, the second hand 4 is moved to the position of the character sign “R” by the forward rotation at the pressing timing t11 of the push button switch B3 (). Step S101). In this case, since it is not an automatic connection, it branches to "NO" in step S102 and the automatic release mode is set (step S111). When the push button switch B3 is pressed within 1.5 seconds (“NO” in step S113, “NO” in step S114, “YES” in step S112), the second hand 4 is placed at the position of the character sign “R”. While maintaining the connection destination information, the connection destination information is acquired (step S103), and the communication connection with the electronic device is started (step S104).

When the communication connection is established (“YES” in step S105), the second hand 4 is moved to the position of the character sign “C” by fast-forwarding in the forward rotation direction (step S106). After branching to "NO" in step S107 according to the automatic release mode setting in step S111 and branching to "NO" in step S108, at the timing t30 when the acquisition of the date and time information is completed (step S141), the electronic device is connected. The communication connection is disconnected (step S142), and the minute hand 3 and the second hand 4 are fast-forwarded to the normal current time display position (step S143).

As shown in FIG. 8C, during the manual connection operation, the second hand 4 is moved to the position of the character sign “R” in the forward rotation at the pressing timing t11 of the push button switch B3 (“NO” in step S101 and step S102. ), The pressed state is maintained as it is (“NO” in step S111 and step S112). At the timing t12 in which the pressed state is continued for 1.5 seconds (“NO” in step S113, “YES” in step S114), the second hand 4 is vibrated near the character sign “R” and the communication connection is manually performed. The mode shifts to the release mode (step S115), and then, at the timing t19 when the pressed state is released (“YES” in step S112), after the connection destination information is acquired (step S103), the communication connection is started (step S103). S104).

At the timing t20 when the communication connection is established (“YES” in step S105), the second hand 4 is moved in the normal direction to the position of the character sign “C” (step S106). In the manual disconnection mode (“YES” in step S107), the communication connection state is maintained until the disconnection operation is input (“NO” in step S121), and the current time counted by the timekeeping circuit 46 is 0 per minute. At the timing of seconds, the new minute value of the current time is compared with the minute value indicated by the minute hand 3. If the compared minute values are different from each other (“YES” in step S122), the second hand 4 is rotated in the forward rotation direction at this timing t22, and the minute value of the time displayed by the minute hand 3 is advanced by 1 minute. The second hand 4 is made to indicate the position of the character sign "C" again (step S123).

At the timing t31 when the disconnection operation is input (“YES” in step S121), the communication connection is disconnected (step S142), and the minute hand 3 and the second hand 4 are fast-forwarded to the current time display position (step S143). ).

As shown in FIG. 8D, during the terminal search operation, the second hand 4 is moved to the position of the character sign “R” in the forward rotation at the pressing timing t11 of the push button switch B3 (“NO” in step S101 and step S102. ), The pressed state is maintained as it is (“NO” in step S111 and step S112). At the timing t12 in which the pressed state is continued for 1.5 seconds (“NO” in step S113, “YES” in step S114), the second hand 4 is vibrated near the character sign “R” and the communication connection is manually performed. The mode shifts to the release mode (step S115).

Further, the pressed state is maintained (“NO” in step S112, “YES” in step S113 at the timing t13 when the pressing duration is 3 seconds or more), and the second hand shifts from the manual release mode to the terminal search mode. 4 is moved to the position of the character sign "F" (step S116). In this case, the communication connection is made after the acquisition of the connection destination information (step S103) regardless of whether or not the pressed state is further continued. It is started (step S104). Even in this case, the communication connection operation may not be started until the pressed state is completed.

At the timing t20 when the communication connection is established (“YES” in step S105), the second hand 4 is moved in the normal direction to the position of the character sign “C” (step S106). In the manual disconnection mode and the terminal search mode (“NO” in step S107, “YES” in step S108), after transmitting a command to cause the electronic device to perform a predetermined notification operation (step S131), the connection disconnection operation is input. The communication connection state is maintained until 30 seconds have elapsed from the establishment of the connection (“NO” in step S132). At the timing when the current time counted by the clock circuit 46 becomes 0 seconds per minute, the new minute value of the current time and the minute value indicated by the minute hand 3 are compared (step S133), but in the present embodiment. In the electronic clock 1, the position of the character marker "R" is the position of 18 seconds, the position of the character marker "C" is the position of 28 seconds, and the character markers "R", "F", are always fast forwarded in the forward direction. Since it is moved to the "C" position in order, the connection is maintained for up to 30 seconds from the establishment of the connection unless the time from the start of the communication connection to the establishment of the connection is longer than usual (within a few seconds) (10 seconds or more). During the period, the minute value indicated by the minute hand 3 is not smaller than the minute value of the current time (“NO” in step S133), and the indicated state of the character sign “C” by the second hand 4 is maintained.

At the timing t31 when the disconnection operation is input or at the timing t30 when 30 seconds have passed from the establishment of the connection (“YES” in step S132), the communication connection is disconnected (step S142), and the minute hand 3 and the second hand 4 are set. It is fast-forwarded to the current time display position (step S143).

Next, the world clock display setting operation will be described. In this world clock display setting operation, the user operates the operation reception unit 48 separately from the case where the time zone and the summer time implementation information of the world clock are acquired as the setting information from the electronic device. It is performed based on the input operation of.

FIG. 9 is a flowchart showing a control procedure by the CPU 41 of the world clock display setting process.
This world clock display setting process is started, for example, by pulling out the crown C1 by one step.

When the world clock display setting process is started, the CPU 41 outputs a control signal to the drive circuit 51 as necessary, and moves the hour hand 6 and the minute hand 7 to positions corresponding to the world clock time (step S301). .. This process is not necessary when the world clock time is displayed from the beginning.
The CPU 41 outputs a control signal to the drive circuit 51, and moves the second hand 4 to a position indicating either the character sign "A" or "P" according to the morning and afternoon of the world clock time (step S302).

The CPU 41 determines whether or not the push-back operation of the crown C1 has been detected (step S303). If it is determined that it has not been detected (“NO” in step S303), then the CPU 41 determines whether or not the rotation operation of the crown C1 has been detected (step S304). If it is determined that it has not been detected (“NO” in step S304), the processing of the CPU 41 proceeds to step S306.

If it is determined that it has been detected (“YES” in step S304), the CPU 41 corrects the counting time according to the detected rotation amount (for example, in units of 15 minutes), and causes the drive circuit 51 to perform the counting time. A control signal is output, and the minute hand 6, the minute hand 7, and the second hand 4 are moved to positions corresponding to the corrected time (step S305). Then, the process of the CPU 41 proceeds to step S306.

When the process proceeds to step S306, the CPU 41 determines whether or not the current time counted by the timekeeping circuit 46 is 0 seconds of each hour and minute, and the minute value indicated by the minute hand 3 deviates from the minute value of the current time. (Step S306). Alternatively, the CPU 41 indicates whether the time corresponding to the position indicated by the minute hand 3 is delayed by 13 seconds or more from the current time when the second hand 4 indicates the character sign "A", or the second hand 4 indicates the character sign "P". Is indicated, it is detected whether the time corresponding to the position indicated by the minute hand 3 is delayed by 8 seconds or more from the current time. If it is not 0 seconds for each hour and minute, or if it is determined that the minute value of the current time and the minute value indicated by the minute hand 3 do not deviate (“NO” in step S306), the processing of the CPU 41 is a step. Return to S303. When it is determined that the deviation is made (“YES” in step S306), the CPU 41 outputs a control signal to the drive circuit 51 and causes the second hand 4 to fast forward in the forward rotation direction at the fastest speed in one round (step S307). .. At this time, the CPU 41 may advance the time indicated by the minute hand 6 and the minute hand 7 by one minute. Then, the processing of the CPU 41 returns to step S303.

When it is determined that the push-back operation of the crown C1 is detected in the determination process of step S303 (“YES” in step S303), the CPU 41 calculates the time difference between the basic clock time and the world clock time, and the world clock time is calculated. It is stored in the RAM 43 as a clock display setting (step S311). Then, the CPU 41 outputs a control signal to the drive circuit 51, and fast-forwards the second hand 4 and the minute hand 3 to a position corresponding to the minute and second of the basic clock (step S312). Then, the CPU 41 ends the world clock display setting process.

As described above, the electronic clock 1 of the present embodiment is interlocked with the rotation of the time counting circuit 46 for counting the current time, the second hand 4 rotatably provided, and the second hand 4, and the rotation of the second hand 4 is performed. A minute hand 3 provided to rotate a rotation angle (6 degrees) smaller than the rotation angle (for example, 360 degrees) with respect to an angle, and a control unit (processor) for controlling the rotation of the second hand 4 and the minute hand 3. ), And when the time display operation is executed, the CPU 41 moves the second hand 4 and the minute hand 3 to a position corresponding to the current time counted by the time counting circuit 46, and has a predetermined function different from the time display operation. At the time of execution of the operation, the second hand 4 is rotated clockwise to move to the position of the character sign corresponding to the state related to the predetermined functional operation, and the second hand 4 changes the display position according to the state related to the predetermined functional operation. While instructing, if the time indicated by the minute hand 3 is delayed from the current time by a predetermined first reference time, for example, 32 seconds or more with respect to the position of the character sign "C", the second hand 4 is rotated. Operate to change the position indicated by the minute hand 3.
As a result, the display time does not lag behind the current time even if the second hand 4 is rotated around for a while after the start of the function operation and the position of the minute hand 3 is not advanced, which causes a problem in the user's time knowledge. While reducing the possibility, the state display related to the function display can be shown without interruption at the beginning of the state. Therefore, the electronic clock 1 can more appropriately balance the display of the time and the display other than the time.
In addition, by aligning the movement of the character sign to the forward rotation (clockwise) fast forward, the user can be informed that the display is changed to the display related to other functional operations or the display is changed to the display related to the other functional operation. It can be shown in an easy-to-understand manner.

Further, the predetermined first reference time is set for each position of the character sign corresponding to each of a plurality of states related to the functional operation. As a result, the timing for changing the value of the minute digit indicated by the minute hand 3 can be aligned or appropriately shifted depending on the position of the character sign.

In particular, the predetermined first reference time depends on the position of the character sign by being determined according to the angle difference between the position of the character sign according to the state and the 0 minute 0 second position of the minute hand 3 and the second hand 4 on the dial 11. Instead, the value of the minute digit indicated by the minute hand 3 can be changed at an appropriate timing according to the current time.

In addition, by appropriately arranging the time display and the status display related to other functional operations by the second hand 4 and the minute hand 3 that rotate in conjunction with each other, the user can be reasonably and appropriately aware of any display. Can be done.

Further, in particular, the predetermined first reference time is determined according to the angle difference between the position of the character sign according to the state of the functional operation and the position where 0 second is indicated by the second hand 4, so that the predetermined first reference time does not depend on the position of the character sign. , The value of the minute digit indicated by the minute hand 3 can be changed at an appropriate timing according to the current time.

Further, the wireless communication unit 49 for transmitting and receiving information to and from an external electronic device is provided, and the predetermined functional operation is at least one of the transmission and reception of the predetermined information by the wireless communication unit 49, and the CPU 41 is a device. The second hand 4 indicates the communication connection state of the wireless communication unit 49 with the electronic device.
As described above, by causing the CPU 41 to perform the above-mentioned control operation for the display of the communication connection operation in the electronic clock 1 which usually has an operation time of about several minutes or less and is hardly expected to continue for a long time. It is possible to effectively maintain and show the user a substantially accurate time display with an error of about 1 minute by the minute hand 3 and a status display of the functional operation by the second hand 4.

Further, when the duration of the state indicated by the second hand 4 is assumed to be equal to or less than a predetermined second reference time, the CPU 41 does not change the position indicated by the minute hand 3 during the state.
That is, if the time lag displayed by the minute hand 3 does not increase during the status display, the process can be simplified by not performing the discrimination process in consideration of the lag from the current time in the first place. In addition, when the function operation ends during the orbital operation of the second hand 4 or immediately after the end of the orbiting operation, the trouble of unnecessarily dividing the fast-forward process is saved, and the timing indicating the end of the function operation is performed. It can be less likely to cause the need to delay.

Further, a predetermined number of states related to a predetermined functional operation are determined, and the CPU 41 rotates the second hand 4 clockwise in response to a change in the state to indicate a position corresponding to the new state. .. That is, the electronic clock 1 is unified by always indicating the state change by fast-forwarding the second hand 4 in the forward rotation direction, and more easily and accurately notifies the user of the functional operation. It is possible to display a substantially accurate time together with the above.

The present invention is not limited to the above embodiment, and various modifications can be made.
For example, in the above embodiment, whether or not the current time is 0 seconds is included in the determination condition, and at the timing of the 0 seconds, it is determined whether or not the second hand 4 is rotated or the position of the minute hand 3 is changed. However, as described above, the condition for making this determination is the time difference between the position (minute / second value) indicated by the minute hand 3 and the current time (minute / second value), that is, the position (minute / second value) indicated by the minute hand 3. Any method can be used as long as the magnitude relationship between the delay of the second value from the current time (minute and second value) and the predetermined reference time can be identified, and it can be either an angle difference or a difference in the number of steps. It may be done on the basis.

Further, in the above embodiment, the case where the time display of the minute hand 3 is continued while the second hand 3 rotating in conjunction with the minute hand 3 displays the state related to the functional operation has been described, but other than this, such as the minute hand and the hour hand. It may be a combination of. Further, three or more pointers may be rotated in conjunction with each other.

Further, in the above embodiment, the case where it is used for displaying the communication connection status related to wireless communication and the case where it is used for displaying the morning and afternoon of the world clock and the alarm notification set time have been described as examples, but the present invention is limited to these. I can't. Further, the number of displayed states is arbitrary, and may be one or more. Further, the positions of the character signs related to these status displays can be arbitrarily arranged, and may be located at positions separated from the dial 11 in the forward rotation direction (clockwise direction) by half a circumference or more. Further, the state display does not have to be indicated by a character sign, and may be a graphic sign, or the hour character used for the time display may be used as a number as it is. Furthermore, even if the watch is not provided with a dial, the directions are fixed with respect to, for example, the push button switches B2, B3 crown C1, and the band for attaching the arm (not shown), and the pointers 2 to 7 are set. It suffices if the position pointed to by can be identified.

Further, in the above embodiment, the second hand 4 is rotated around the timing when the current time reaches 0 seconds to advance the position of the minute hand 3, but the present invention is not limited to this. The timing may be another second value, or the second hand 4 may be rotated 30 seconds after the time (second value) corresponding to the position of each character sign. That is, the second hand 4 may be rotated and the minute hand 3 may be moved at different timings according to the position of the designated character sign.

Further, in the above embodiment, when the position of the character sign "R" is instructed, it has been described that the second hand 4 is not fast-forwarded from the beginning. If it takes time to capture or establish a communication connection, and if a predetermined delay time occurs at the time indicated by the position indicated by the minute hand 3 with respect to the current time with the character sign "R", the same applies. The second hand 4 may be fast-forwarded around. Further, the second hand 4 may be fast-forwarded around at the timing when a predetermined delay time occurs uniformly, regardless of the instructed character sign.

Further, in the above embodiment, the CPU 41 is used to perform all operations as a control unit (processor), but processing by a hardware circuit such as a dedicated logic circuit may be included.

Further, in the above embodiment, the case of communication connection by Bluetooth has been described as an example, but the same operation is performed in the electronic clock 1 when communication connection is made with an external electronic device using another communication protocol. Can be done. Further, the present invention can be similarly applied not only to the transmission and reception of information but also to an electronic clock that unilaterally receives a transmission radio wave and acquires necessary information.
In addition, specific details such as the configuration, control procedure, and display example shown in the above embodiment can be appropriately changed without departing from the spirit of the present invention.

Although some embodiments of the present invention have been described, the scope of the present invention is not limited to the above-described embodiments, but includes the scope of the invention described in the claims and the equivalent scope thereof.
