Description

The present invention relates to an analog electronic timepiece, an analog electronic timepiece control method, and an analog electronic timepiece control program.

Analog electronic watches are known in which the hour and minute hands have the function of displaying information other than time. Conventionally, such analog electronic watches have adopted a user interface in which functions are sequentially changed by operating a switch. With conventional user interfaces, when multiple functions that require two or more time hands to display information (e.g. calendar display function, dual time display function, etc.) are installed, it is difficult to identify each function. It may cause misreading. When functions that require one stitch or multiple stitches to display information are mixed, it becomes even more difficult to identify the functions.

For example, in the analog electronic watch described in Patent Document 1, information other than time is displayed by driving the hour hand and minute hand to selectively overlap the angular position corresponding to information other than time. In this case, the longer the number of characters or the greater the number of functions, the more content must be written on the dial plate, which not only reduces the size of the characters and impairs visibility, but also reduces the degree of freedom in design.

In an analog electronic watch whose hour and minute hands have the function of displaying information other than time, if multiple switches correspond to the operation of switching to a different function, when a certain function is being executed, If an operation to be performed corresponds to multiple switches, the function may switch to a different function.

The communication start function is a function for starting wireless communication by the communication unit 20.

Regardless of which function is the active function that is currently being executed, if switch C is pressed for a predetermined period of time (for example, 2 seconds) or more, the active function is switched to the automatic time synchronization function. The automatic time synchronization function is a function that turns on and off the process of acquiring time information from an external device and performing time synchronization. Wireless communication with external devices is performed via the communication unit 20 as described above.

Next, with reference to FIG. 4, details of the process in which the active function is switched and each function is executed will be described. FIG. 4 is a diagram showing an example of processing by the function management unit 145 according to the present embodiment. The process shown in FIG. 4 by the function management unit 145 is repeatedly executed at predetermined intervals. The predetermined period is, for example, the number of clocks of a CPU (Central Processing Unit) provided in the control circuit 14.

The function management unit 145 determines whether the active function is not a time display function (step S10). When determining that the active function is the time display function (step S10; YES), the function management unit 145 executes the process of step S20. On the other hand, if it is determined that the active function is not the time display function (step S10; NO), the process of step S30 is executed.

The function management unit 145 determines whether a predetermined time has not elapsed since any one of switch A, switch B, and switch C was operated (step S20). Here, the time management section 149 measures the time that has passed since the function management section 145 received the operation signal from the input circuit 13 . The function management unit 145 acquires the time measured by the time management unit 149 and makes a determination based on the acquired time.
If the function management unit 145 determines that a predetermined time has passed since the switch was operated (step S20; YES), it executes the process of step S30. On the other hand, if the function management unit 145 determines that the predetermined time has not passed since the switch was operated (step S20; NO), it executes the process of step S40.

The function management unit 145 determines whether a predetermined operation has been performed on any one of switch A, switch B, and switch C (step S30). The predetermined operation is an operation in which a switch is pressed for a predetermined time (for example, 2 seconds) or less. The function management unit 145 makes a determination based on the operation signal received from the input circuit 13.

If the function management unit 145 determines that a predetermined operation has been performed on the switch (step S30; YES), it executes the process of step S50. On the other hand, when the function management unit 145 determines that the predetermined operation is not performed on the switch (step S30; NO), the function management unit 145 ends the process.

The function management unit 145 switches the active function to the time display function (step S40). In other words, when a predetermined period of time has elapsed since switching the active function to the function associated with the switch on which the predetermined operation was performed, the function management unit 145 switches the active function from the function to the time display function. .
After that, the function management unit 145 ends the process.

The function management unit 145 determines whether the operated switch is a switch associated with an active function (step S50). That is, for example, when the active function is a time display function, the function management unit 145 determines whether switch B corresponding to the time display function has been operated. When the function management unit 145 determines that the operated switch is not a switch associated with an active function (step S50; NO), the function management unit 145 performs one of step S70, step S80, and step S90 depending on the operated switch. This process is caused to be executed by one of the time display function section 146, calendar display function section 147, and dual time display function section 148.
On the other hand, when the function management unit 145 determines that the operated switch is a switch associated with an active function (step S50; YES), it executes the process of step S60.

The function management unit 145 switches the active function to the function corresponding to the operated switch (step S60). For example, when the active function is a time display function and switch B is operated, if the current display is hour/minute display, the display is switched to minute/second display. On the other hand, if the current display is minutes/seconds, the display is switched to hours/minutes. After that, the process ends.
Note that the processes in step S50 and step S60 may be omitted. In that case, if it is determined in step S30 that a predetermined operation has been performed on any one of switch A, switch B, and switch C, the function management unit 145 performs step S70 according to the operated switch. , step S80, and step S90 are caused to be executed by one of the time display function section 146, calendar display function section 147, and dual time display function section 148.

[Time display function]
When switch B is operated, the function management unit 145 causes the time display function unit 146 to execute the time display function (step S70). When the time display function section 146 starts the time display function, it switches the display to hour/minute display. The time display function unit 146 switches the display to minutes/seconds when the current display is hours/minutes, and switches the display to hours/minutes when the current display is minutes/seconds. Switch to. That is, the time display function section 146 alternately switches between hour/minute display and minute/second display each time switch B is operated in a predetermined manner. In the hour/minute display, the hour and minute of the current time are indicated by an hour hand 191 and a minute hand 192, respectively. In the minute/second display, the minutes and seconds of the current time are indicated by an hour hand 191 and a minute hand 192, respectively.

[Calendar display function]
When switch A is operated, the function management unit 145 causes the calendar display function unit 147 to execute the calendar display function (step S80). When the calendar display function section 147 starts the calendar display function, it switches the display to month/day display. The calendar display function unit 147 switches the display to the day/day of the week display when the current display is the month/day display, and switches the display to the month/day display when the current display is the day/day of the week display. Switch to. That is, the calendar display function section 147 alternately switches between month/day display and day/day of the week display each time switch A is operated in a predetermined manner. In the month/day display, the month and date are indicated by an hour hand 191 and a minute hand 192, respectively. In the day/day of the week display, the date and day of the week are indicated by an hour hand 191 and a minute hand 192, respectively.

[Dual time display function]
When the switch C is operated, the function management unit 145 causes the dual time display function unit 148 to execute the dual time display function (step S90). When the dual time display function section 148 starts the dual time display function, it switches the display to the first city display. The dual time display function unit 148 switches the display to the second city display when the current display is the first city display, and switches the display to the first city display when the current display is the second city display. Switch to display. That is, the dual time display function section 148 alternately switches between the first city display and the second city display each time switch C is operated in a predetermined manner. Here, in the first city display, the time of the first city (or region) is indicated by an hour hand 191 and a minute hand 192. In the second city display, the time of the second city (or region) is indicated by an hour hand 191 and a minute hand 192.
With this, the function management unit 145 ends the process.

As described above, the operation regarding the time display function is performed by switch B, which is a switch associated with the time display function. Operations regarding the calendar display function are performed by switch A, which is a switch associated with the calendar display function. The dual time display function is operated by switch C, which is a switch associated with the dual time display function.
In other words, the operation for the first function of displaying information using both the hour hand 191 and the minute hand 192 is performed by the switch associated with the first function among the plurality of switches.

Note that if the switch associated with the function is operated after switching the active function to the function associated with the switch, the function management unit 145 extends the predetermined time determined in step S20. You can. In that case, the function management unit 145 extends the predetermined time by 10 seconds, for example.

Note that in step 30, when the active function is a time setting function, if switch A and switch C are pressed simultaneously for a predetermined period of time or more (for example, 10 seconds), the function management unit 145 sets the active function to the time setting function. Switch to the settings function. Further, in step 30, the function management unit 145 switches the active function to the calendar setting function when the active function is the calendar display function. Further, in step 30, the function management unit 145 switches the active function to the dual time time difference setting function when the active function is the dual time display function.
In other words, when two switches are operated at the same time, the function management unit 145 switches the active function to a function that performs settings for the function associated with the switch.

Note that the analog electronic watch 1 may have other functions instead of the dual time display function. For example, the analog electronic watch 1 may have any one of a timer function, an alarm function, and a stopwatch function instead of the dual time display function. In the following, a case will be described in which the analog electronic watch 1 has a timer function, an alarm function, and a stopwatch function.

[Timer function]
When the analog electronic watch 1 includes a timer function, for example, in the control circuit 14 shown in FIG. 1, the power source control section 143 includes a timer function section 148a instead of the dual time display function section 148. The timer function section 148a executes control regarding the timer function.

In the process shown in FIG. 4, when switch C is operated in step S30, the function management unit 145 causes the timer function unit 148a to execute the timer function in step S90. When the timer function section 148a starts the timer function, the timer function section 148a starts counting by the timer. In this timer function, for example, a down count is performed in which the value of the timer decreases over time. The timer function unit 148a stops counting if the timer is currently counting, and starts counting by the timer if the counting is currently stopped. That is, the timer function unit 148a alternately starts and stops counting by the timer every time the switch C is operated in a predetermined manner.

Note that the timer function by the timer function section 148a is not limited to the above-mentioned one. As another example, when the timer function unit 148a starts the timer function, it sets the timer value to an initial value (for example, 3 minutes) and waits. The timer function unit 148a starts counting by the timer when the second predetermined operation is performed on the switch C after starting the timer function. The timer function unit 148a stops counting when the third predetermined operation is performed on the switch C after starting the timer function. The timer function unit 148a restarts counting by the timer when the fourth predetermined operation is performed on the switch C after starting the timer function. Note that the timer function unit 148a may reset the timer count when the fourth predetermined operation is performed on the switch C after starting the timer function.

When a predetermined period of time (for example, 10 seconds) elapses while the timer is stopped, the active function is switched to the time display function. Furthermore, when a predetermined period of time (for example, 10 seconds) has elapsed after the timer count reaches 0 seconds, the active function is switched to the time display function.

Note that when switch A and switch C are pressed down simultaneously for a predetermined period of time (for example, 2 seconds) or more, the active function is switched to the timer setting function. The timer setting function is a function for setting the initial value of the timer. The initial value of the timer may be set by being operated from an external device through wireless communication by the communication unit 20.

[Alarm function]
When the analog electronic timepiece 1 includes an alarm function, for example, in the control circuit 14 shown in FIG. 1, the power source control section 143 includes an alarm function section 148b instead of the dual time display function section 148. The alarm function section 148b executes control regarding the alarm function. Note that when the analog electronic timepiece 1 is provided with an alarm function, the analog electronic timepiece 1 is provided with a speaker and sound source data for producing an alarm sound or the like.

In the process shown in FIG. 4, when switch C is operated in step S30, the function management section 145 causes the alarm function section 148b to execute the alarm function in step S90. When the alarm function section 148b starts the alarm function, it turns on the alarm. The alarm function unit 148b turns off the alarm when the alarm is currently on, and turns on the alarm when the alarm is currently off. That is, the alarm function section 148b alternately switches the alarm on and off every time the switch C is operated in a predetermined manner.

Note that the alarm function by the alarm function section 148b is not limited to the above-mentioned one. As another example, when the alarm function is started, the alarm function section 148b displays the distinction between AM and PM, and when a predetermined time (for example, 1 second) has elapsed, displays the time set as the alarm time. do. Note that the alarm function unit 148b displays the distinction between alarm on and off before displaying the distinction between AM and PM, and after a predetermined time (for example, 1 second) has elapsed, the alarm function section 148b displays the distinction between AM and PM. You may also indicate the distinction between The alarm function unit 148b switches the alarm between on and off when the second predetermined operation is performed on the switch C after starting the alarm function.

When a predetermined period of time (for example, 10 seconds) has elapsed since the active function was switched to the alarm function, the active function is switched to the time display function.

In addition, when displaying the distinction between alarm on and off, the alarm function unit 148b, for example, overlaps the hour hand 191 and the minute hand 192 and displays the characters "ON" or "OFF" on the dial BD. You can give instructions or make sounds.

Note that when switch A and switch C are pressed down simultaneously for a predetermined period of time (for example, 2 seconds) or more, the active function is switched to the alarm setting function. The alarm setting function is a function for setting an alarm time. The alarm time may be set by being operated from an external device through wireless communication by the communication unit 20.

[Stopwatch function]
When the analog electronic timepiece 1 includes a stopwatch function, for example, in the control circuit 14 shown in FIG. 1, the power source control section 143 includes a stopwatch function section 148c instead of the dual time display function section 148. The stopwatch function unit 148c executes control regarding the stopwatch function.

In the process shown in FIG. 4, when switch C is operated in step S30, the function management unit 145 causes the stopwatch function unit 148c to execute the stopwatch function in step S90. When the stopwatch function section 148c starts the stopwatch function, it starts measuring time. The stopwatch function unit 148c stops timekeeping when timekeeping is in progress, and starts timekeeping when timekeeping is stopped. In other words, the stopwatch function section 148c alternately starts and stops timekeeping using the stopwatch function each time the switch C is operated in a predetermined manner.

Note that the stopwatch function by the stopwatch function section 148c is not limited to that described above. As another example, when the stopwatch function unit 148c starts the stopwatch function, the stopwatch function unit 148c moves the hour hand 191 and the minute hand 192 to an initial position (for example, the 12 o'clock position) so that they overlap. When the second predetermined operation is performed on switch C after starting the stopwatch function, the stopwatch function section 148c moves the minute hand 192 every 1 second and moves the hour hand 191 every 60 seconds. move it to That is, the minute hand 192 and the hour hand 191 correspond to seconds and minutes, respectively. The stopwatch function unit 148c stops timing when the third predetermined operation is performed on switch C after starting the stopwatch function. The stopwatch function unit 148c restarts timekeeping when the fourth predetermined operation is performed on switch C after starting the stopwatch function. Note that the stopwatch function unit 148c may reset the time count when the fourth predetermined operation is performed on the switch C after starting the stopwatch function.

In the stopwatch function, when 60 minutes have elapsed since timekeeping started, the active function is switched to the time display function. Further, when the time measurement is stopped and a predetermined period of time (for example, 10 seconds) has elapsed, the active function is switched to the time display function.

As explained above, the analog electronic watch 1 according to the present embodiment is an analog electronic watch that displays a plurality of pieces of information based on the angular position using only the hour hand 191 and the minute hand 192, and includes a plurality of switches (as described above). (in the embodiment, switch A, switch B, and switch C), and a control unit (function management unit 145 in the above-described embodiment). The plurality of switches are respectively associated with a plurality of functions for displaying information indicated by the hour hand 191 and the minute hand 192. When a predetermined operation is performed on the switch (in the above-described embodiment, the switch is pressed for 2 seconds or less), the control unit activates the current function (in the above-described embodiment, the active function) which is the function to be currently executed. to the function associated with the switch.
The functions include a plurality of first functions (in the embodiments described above, a time display function, a calendar display function, a dual time display function, a timer function, and an alarm function) that display information using both the hour hand 191 and the minute hand 192. and a stopwatch function), and the number of the plurality of switches is equal to the number of the plurality of first functions. The operation regarding the first function is performed by a switch associated with the function among the plurality of switches.

With this configuration, the analog electronic watch 1 according to the present embodiment has the same number of switches and the same number of functions when each of the plurality of switches corresponds to an operation of switching to a different function. Since a function can be operated using a switch associated with the function, switching to another function while one function is being executed can be suppressed.

Note that all or part of the functions of the analog electronic timepiece 1 described above may be recorded as a program on a computer-readable recording medium, and this program may be executed by a computer system. It is assumed that the computer system includes hardware such as peripheral devices.
Computer-readable recording media include, for example, portable media such as flexible disks, magneto-optical disks, ROMs (Read Only Memory), and CD-ROMs, storage devices such as hard disks built into computer systems, and storage devices such as the Internet. This is volatile memory (Random Access Memory: RAM) provided in servers and the like on a network. Note that volatile memory is an example of a recording medium that retains a program for a certain period of time.

Further, the above-mentioned program may be transmitted to another computer system via a transmission medium, for example, a network such as the Internet, or a communication line such as a telephone line.
Furthermore, the program may be a program that implements all or part of the functions described above. Note that the program that implements some of the above-mentioned functions may be a so-called difference program, which is a program that can implement the above-mentioned functions in combination with a program recorded in advance in the computer system.
