  By the way, an analog clock is actually mounted on a portable device that is a host device, and the time is displayed on the analog clock portion. In order to synchronize the time of the portable device and the time of the analog clock, When the time is counted separately for each device, and the synchronization is established and synchronized as a result, when the time of the analog clock must be delayed, it is necessary to reverse the motor that moves the hands. In order to reversely rotate the motor that moves the hands, the analog timepiece requires a motor reverse drive circuit, which increases the circuit size of the analog timepiece, and the analog timepiece is set to the correct time or hand position from the portable device.

A pointer driving signal is input to the pointer driving control means, and it is possible to switch between performing control for moving the hands of the analog timepiece based on the pointer driving signal.

  According to the present invention, when the portable information device is approaching a state where the portable information device itself cannot operate, the pointer drive control means itself performs control to move the hands of the analog timepiece, When the operation of the information device itself is sufficiently possible, the pointer drive signal output from the portable information device is input to the pointer drive control means, and the hand of the analog timepiece is changed based on the pointer drive signal. It is characterized by performing a moving control.

  In the present invention, the pointer drive signal is output when the pointer drive signal output from the portable information device is input to the pointer drive control means and the pointer of the analog timepiece is controlled to move based on the pointer drive signal. When the signal is not input for a predetermined time, the hand drive control means performs switching so that the hand drive control means itself performs control to move the hand of the analog timepiece.

Then, the pointer drive control unit 11 outputs the information on the read driving pulse for driving to the motor drive circuit 12. In response to this, the motor drive circuit 12 sets the driving pulse for driving to be output to the motor 13 based on the information on the driving pulse for driving outputted from the pointer drive control unit. When the pointer driving signal is output to the motor driving circuit 12 by this setting, the set driving pulse for driving is given to the motor 13, and for example, the second hand moves for one second.

  Next, the pointer drive control unit 11 outputs a pointer drive signal to the motor drive circuit 12 every time a hand movement timing signal output from the oscillation circuit 16 is output. In response to this, the motor drive circuit 12 outputs the previously set driving pulse for driving to the motor 13. As a result, the motor 13 is rotated, and the rotation operation of the rotating shaft of the motor 13 is transmitted to the pointer 10 via the wheel train 14, and the pointer 10 moves.

  Next, with reference to FIG. 2, the operation | movement which synchronizes the time display of the analog timepiece 1 shown in FIG. 1 and the portable information device 2 is demonstrated.

It is assumed that the control switching information storage unit 18 stores information indicating that the hand movement is performed based on the hand movement instruction information output from the portable information device 2. First, the control unit 21 updates time information by counting signals output from the oscillation circuit 26 (step S1). Then, the control unit 21 determines whether it is time to drive the pointer 10 (1 second if a second hand is provided, or 1 minute if a second hand is not provided and only a minute hand and an hour hand). Is determined (step S2). As a result of the determination, if it is not time to drive the pointer 10, the process returns to step S1. On the other hand, when it is time to drive the hands 10, the control unit 21 outputs a hand drive signal to the analog timepiece 1 via the communication unit 27 (step S 3) and hands to the storage unit 25. The position information (pointing time information) is stored (step S4).

  On the other hand, the pointer drive control unit 11 determines whether or not a pointer drive signal is output from the portable information device 2 (step S5). If the result of this determination is that the pointer drive signal has not been output, it waits until it is output. When the pointer drive signal is input to the pointer drive control unit 11 via the communication unit 19, the pointer drive control unit 11 outputs the pointer drive signal to the motor drive circuit 12 (step S6). In response to this, the motor drive circuit 12 outputs the previously set driving pulse for driving to the motor 13. As a result, the motor 13 is rotated, and the rotation operation of the rotating shaft of the motor 13 is transmitted to the pointer 10 via the wheel train 14, and the pointer 10 moves.

As a result of this determination, if the information indicating that the pointer control is switched is not output, the normal operation shown in FIG. 2 is continued. On the other hand, when information indicating that the pointer control is switched is output from the portable information device 2, the pointer drive control unit 11 inputs the needle position information output from the portable information device 2 via the communication unit 19. In step S15, the input hand position information is stored in the storage unit 17, and information indicating that the analog timepiece 1 itself controls the hand movement is stored in the control switching information storage unit 18.

  The pointer drive control unit 11 updates the time information by counting the signals output from the oscillation circuit 16 (step S16). Then, the pointer drive control unit 11 determines whether or not it is time to drive the pointer 10 (step S17). As a result of this determination, if it is not time to drive the pointer 10, the process returns to step S16. On the other hand, when it is time to drive the pointer 10, the pointer drive control unit 11 outputs a pointer drive signal to the motor drive circuit 12 (step S18). In response to this, the motor drive circuit 12 outputs the previously set driving pulse for driving to the motor 13. As a result, the motor 13 is rotated, and the rotation operation of the rotating shaft of the motor 13 is transmitted to the pointer 10 via the wheel train 14, and the pointer 10 moves. Subsequently, the pointer drive control unit 11 stores the needle position information in the storage unit 17 (step S19).

  Next, with reference to FIG. 4, an operation for switching the hand movement control when the time display of the analog timepiece 1 and the portable information device 2 shown in FIG. 1 is synchronized will be described. FIG. 4 is a flowchart showing an operation for switching the hand movement control when the time display of the analog timepiece 1 and the portable information device 2 shown in FIG. 1 is synchronized. First, the control unit 21 detects the voltage of the power supply 24, and when the power supply voltage becomes equal to or higher than a predetermined value (for example, the lowest voltage at which the portable information device can operate) (step S21), the control unit 21 performs analog processing via the communication unit 27. Information indicating that the pointer control is switched to the portable information device 2 is output to the timepiece 1 (step S22). And the control part 21 inputs the hand position information output from the analog timepiece 1 via the communication part 27 (step S23), memorize | stores it in the memory | storage part 25, and returns to normal operation | movement shown in FIG.

  On the other hand, the pointer drive control unit 11 performs control switching when the pointer control shifts to the portable information device 2 based on whether or not information indicating that the pointer control is switched is output from the portable information device 2 (step S24). Information indicating that the portable information device 2 controls the hand movement is stored in the information storage unit 18.

First, referring to FIG. 5, an operation for switching the hand movement control when the time display of the analog timepiece 1 and the portable information device 2 shown in FIG. 1 is synchronized will be described. FIG. 5 is a flowchart showing an operation for switching the hand movement control when the time display of the analog timepiece 1 and the portable information device 2 shown in FIG. 1 is synchronized. First, the control unit 21 detects the voltage of the power supply 24 and determines whether or not the power supply voltage has become equal to or lower than a predetermined value (for example, the lowest voltage at which the portable information device can operate) (step S31). If the result of this determination is not less than or equal to the predetermined value, the normal operation shown in FIG. 2 is continued. On the other hand, when the power supply voltage is equal to or lower than the predetermined value, the control unit 21 outputs information indicating that the hand control is switched to the analog timepiece 1 to the analog timepiece 1 via the communication unit 27 (step S32).

  The pointer drive control unit 11 determines whether or not the pointer control has shifted to the analog timepiece 1 based on whether or not information indicating that the switching of the pointer control is performed from the portable information device 2 (Step S33). ). As a result of the determination, if information indicating that the pointer control is switched is not output, the normal operation shown in FIG. 2 is continued. On the other hand, when the information indicating that the pointer control is switched is output from the portable information device 2, the pointer drive control unit 11 indicates that the analog timepiece 1 itself controls the hand movement in the control switching information storage unit 18. Store information.

  Next, the pointer drive control unit 11 updates the time information by counting the signals output from the oscillation circuit 16 (step S34). Then, the pointer drive control unit 11 determines whether or not it is time to drive the pointer 10 (step S35). If the result of this determination is that it is not time to drive the pointer 10, the process returns to step S34. On the other hand, when it is time to drive the pointer 10, the pointer drive control unit 11 outputs a pointer drive signal to the motor drive circuit 12 (step S36). In response to this, the motor drive circuit 12 outputs the previously set driving pulse for driving to the motor 13. As a result, the motor 13 is rotated, and the rotation operation of the rotating shaft of the motor 13 is transmitted to the pointer 10 via the wheel train 14, and the pointer 10 moves. Subsequently, the pointer drive control unit 11 increments the number of hand movement steps of the pointer 10 stored in the storage unit 17 (the number of times of hand movement, which corresponds to the number of seconds if the hand is moved for 1 second). Update (step S37). As a result, the storage unit 17 stores the number of hand movement steps that have progressed to the elapsed time during which the pointer control is shifted to the analog timepiece 1 (the elapsed time is expressed in seconds if the hand is one second). Will be remembered.

  Next, with reference to FIG. 6, an operation for switching the hand movement control when the time display of the analog timepiece 1 and the portable information device 2 shown in FIG. 1 is synchronized will be described. FIG. 6 is a flowchart showing an operation of switching the hand movement control when the time display of the analog timepiece 1 and the portable information device 2 shown in FIG. 1 is synchronized. First, the control unit 21 detects the voltage of the power supply 24, and when the power supply voltage becomes equal to or higher than a predetermined value (for example, the lowest voltage at which the portable information device can operate) (step S41), the control unit 21 performs analog processing via the communication unit 27. Information indicating that the pointer control is switched to the portable information device 2 is output to the timepiece 1 (step S42). And the control part 21 inputs the information of the hand movement step number output from the analog timepiece 1 via the communication part 27 (step S43), and with respect to the hand position information memorize | stored in the memory | storage part 25, a hand movement step The number is added to update the current needle position information, and the operation returns to the normal operation shown in FIG.

  On the other hand, when the pointer control is transferred to the portable information device 2 based on whether or not the information indicating that the switching of the pointer control is performed is output from the portable information device 2 (step S44), the pointer drive control unit 11 performs the control switching. Information indicating that the portable information device 2 controls the hand movement is stored in the information storage unit 18. The pointer drive control unit 11 outputs the information on the number of steps of the needle 10 stored in the storage unit 17 to the portable information device 2 via the communication unit 19 (step S45), and performs the normal operation shown in FIG.

  In the first and second embodiments, the power supply 15 shown in FIG. 1 is not necessarily provided. The power of the power supply 24 is supplied to the analog timepiece 1, and the power supply of the analog timepiece 1 and the portable information device 2 is shared. It may be a power source of

<Third Embodiment>
Next, a portable information device including an analog timepiece according to the third embodiment of the present invention will be described. Since the configuration of the portable information device provided with the analog timepiece in the third embodiment is the same as the configuration shown in FIG. 1, the detailed description of the configuration is omitted. Referring to FIG. 7, when synchronizing the time display of the analog timepiece 1 and the portable information device 2 shown in FIG. 1, the analog timepiece 1 automatically performs the pointer control when the pointer driving signal is not output for some reason. The operation for switching will be described. FIG. 7 is a flowchart showing an operation in which the analog timepiece 1 automatically switches the pointer control when the time display of the analog timepiece 1 and the portable information device 2 shown in FIG. 1 is synchronized.

  First, the pointer drive control unit 11 determines whether a pointer drive signal is output from the portable information device 2 (step S51). When the pointer driving signal is input via the communication unit 19, the pointer driving control unit 11 outputs the pointer driving signal to the motor driving circuit 12 (step S52). In response to this, the motor drive circuit 12 outputs the previously set driving pulse for driving to the motor 13. As a result, the motor 13 is rotated, and the rotation operation of the rotating shaft of the motor 13 is transmitted to the pointer 10 via the wheel train 14, and the pointer 10 moves.

  On the other hand, when the pointer drive signal is not input, the pointer drive control unit 11 determines whether or not the continuation time during which the pointer drive signal is not input has reached a predetermined time (for example, 1 second) or more (step S53). When the continuation time during which no is input becomes equal to or longer than a predetermined time, information indicating that the analog timepiece 1 controls the hand movement is stored in the control switching information storage unit 18 and the hand control is switched to the analog timepiece 1 itself ( Step S54).

  Next, the pointer drive control unit 11 updates the time information by counting the signal output from the oscillation circuit 16 (step S55). Then, the pointer drive control unit 11 determines whether or not it is time to drive the pointer 10 (step S56). As a result of this determination, if it is not time to drive the pointer 10, the process returns to step S55. On the other hand, when it is time to drive the pointer 10, the pointer drive control unit 11 outputs a pointer drive signal to the motor drive circuit 12 (step S57).

  In response to this, the motor drive circuit 12 outputs the previously set driving pulse for driving to the motor 13. As a result, the motor 13 is rotated, and the rotation operation of the rotating shaft of the motor 13 is transmitted to the pointer 10 via the wheel train 14, and the pointer 10 moves. Subsequently, the pointer drive control unit 11 increments and updates the number of hand movement steps of the pointer 10 stored in the storage unit 17 (the number of times of one-second hand movement corresponds to the number of seconds) (step S58). ). As a result, the storage unit 17 stores the value expressed in seconds while the pointer control is shifted to the analog timepiece 1 side. Then, when the pointer driving signal is normally input, the processing operation of steps S42 to S45 shown in FIG. 6 is executed, and then the operation returns to the normal operation.

  As described above in the first to third embodiments, in the electric analog timepiece, it is possible to select whether the analog timepiece itself performs control for moving the hands or the portable information device via communication. Therefore, when the power source of the portable information device 2 is a voltage sufficient for operation, the portable information device controls the pointer 10 of the analog timepiece 1 via communication, and the power source voltage becomes such that the portable information device 2 cannot operate. The analog timepiece 1 itself can be switched so as to control the hands 10, and the operation of the analog timepiece can be continued without stopping. In addition, when the portable information device 2 switches from the state in which the handheld information device 2 controls the hand 10 to the state in which the analog timepiece 1 controls the hand 10, the hand position information is notified from the portable information device 2 to the analog timepiece 1. The display time of the portable information device 2 and the analog timepiece 1 can be completely matched.

  Further, when the portable information device 2 returns to an operable power supply voltage, the portable information device 2 is switched again to perform the pointer control of the analog timepiece 1, so that the portable information device 2 and the analog timepiece 1 are switched. Display time lag can be minimized. At this time, since the hand position information of the analog timepiece 1 is notified to the portable information device 2, the display time can be completely matched between the portable information device 2 and the analog timepiece 1.

  In addition, when the pointer driving signal is not output from the portable information device 2 for some reason, the analog timepiece 1 itself automatically switches the pointer control. Can be prevented from being displayed.

  Further, when the analog timepiece 1 itself controls the hand 10, the oscillation circuit 16 of the analog timepiece 1 operates, and when controlled by the portable information device 2, the operation of the oscillation circuit 16 can be stopped. Therefore, the power consumed by the analog timepiece 1 can be reduced. Further, since the analog timepiece 1 and the portable information device 2 are provided with different power sources, the analog timepiece 1 can continue to operate even when the power supply of the portable information device is disconnected.

  A program for realizing the functions of the pointer drive control unit 11 and the control unit 21 shown in FIGS. 1, 2, and 3 is recorded on a computer-readable recording medium, and the program recorded on the recording medium is stored in a computer system.
