By the way, the exercise time (for example, the time during jogging) is measured by the stopwatch function or the subtraction timer function of the multifunctional pointer type electronic wrist watch as described above. In this case, it is preferable to use it with the upper case closed, considering the convenience of carrying it during exercise. However, prior to measuring the exercise time, if you had adopted a function such as the data bank function to open the upper case and use the display on the lower surface, inadvertently open the upper case and operate the switch to start the measurement. In such a case, the upper case is hurriedly closed after that, and then the exercise is started. Therefore, in such a case, the measurement start time and the exercise start time are slightly deviated from each other, and the measured exercise time becomes inaccurate. The present invention is
This is done in view of the circumstances as described above, and after closing the upper case, the measurement start operation is performed at the place where the measurement start operation should be started in accordance with the start of the measurement target motion. After the measurement start operation, the upper case is closed to start the measurement target operation. An object of the present invention is to provide an electronic device with a freely openable / closable case that can avoid an error in the measurement result due to the above.

[0004]

According to the invention of claim 1, when a measurement start operation is performed while the upper case is open, the measurement is started after a lapse of a predetermined time from the time of the operation. In the invention of claim 2, when the measurement start operation is performed while the upper case is opened, the measurement is started when the upper case is closed thereafter.

FIG. 3 is a flow chart showing the operation of this embodiment. Hereinafter, with reference to this flow chart,
The operation in various states will be described. (A) Operation when the upper case 31 is opened and the timer mode is set and the timer time is set When the upper case 31 is opened and the timer mode is set, the second liquid crystal display panel 35 of the second display unit 20 is operated. The mode switch SM of the second switch section 16 is operated until the timer time is displayed. At this time, the following operation is performed every time the operation is performed. That is, the value of the measuring flag FS is not 1 in step S1 and the subtraction timer 12 is still in use.
It is judged that the measurement by is not started, and the step S
2, the value of the standby flag FA is not 1 and it is determined that the start / stop switch S1 is not operated, and the process proceeds to step S20. In step S20, it is determined that the output of the optical sensor 14 is at the H level instead of the L level, and the upper case 31 is in the open state. Then, the process proceeds to step S45, where the value of the open state flag FT is not 0 but 1 31 determines that it is open, and step S55
Then, it is determined that there is no switch input signal from the first switch section 15, and the process proceeds to step S62. This step S
In 62, it is detected that there is a switch input signal from the second switch section 16, in the next step S63 it is determined that the mode switch SM is operated, and in step S64 the mode is changed, Go to S50,
The value of the second display unit mode register LM is 1 and it is determined whether the timer mode is set. When the timer mode is set, the second liquid crystal display panel 35 of the second display unit 20 is set in step S51.
The timer time is displayed at (however, at this time, 0 hours 00 minutes is displayed because the timer time has not been set yet), and the process returns to step S1.

In order to set the timer time in the subtraction timer 12 after setting the timer mode in this way, the second switch section 16, that is, the ten-key pad of the key arranging section 36 is operated.
At this time, the following operations are performed each time the ten key is operated. That is, the same operation as described above is performed, it is detected in step S62 that there is a switch input signal from the second switch section 16, and it is determined in step S63 that the mode switch SM has not been operated. In S65, it is determined that the value of the second display mode register LM has already become 1 and the timer mode is set. Then, in Step S66, a process of setting the timer time in the subtraction timer 12 is executed. Next, in step S50, it is confirmed again that the value of the second display mode register LM is 1 and the timer mode is set, and the timer time set in the next step S51 is displayed on the second liquid crystal display panel 35. Then, the process returns to step S1.

(B) Operation when the subtraction timer 12 is operated to switch the measurement with the upper case 31 opened The timer mode is set with the upper case 31 open as described above, and further movements to be performed When the start / stop switch S1 is operated to instruct the subtraction timer 12 to start the subtraction timer operation without closing the upper case 31 after setting the exercise time (for example, jogging) as the timer time in the subtraction timer 12. , It is detected in step S56, the process proceeds to step S57, the value of the in-measuring flag FS is 0, it is judged that the measurement operation by the subtraction timer 12 is not yet started, and it is set in the subtraction timer 12 in step S58. Timer time is 0 hours 0
Make sure it's not 0 minutes. Then, step S59
Then, the value of the standby flag FA is set to 1 and the fact that the above measurement is not started for 10 seconds thereafter is stored. After that,
The process returns to step S1 through steps S62, S50 and S51.

Then, for the next 10 seconds, the following operation is repeated to wait for the start of measurement by the subtraction timer 12. That is, in step S1, it is confirmed that the value of the in-measuring flag FS has not become 1 yet and the measurement is not started at 0, and the process proceeds to step S2, in which the value of the waiting flag FA is 1 and the above-mentioned 10 seconds. After confirming that it is waiting, the process proceeds to the next step S3. In step S3, it is judged whether or not it is the sounding timing for every one second, and if it is not this timing, the process proceeds to step S20, but at this timing, the process proceeds to step S4 and a signal is sent to the sounding device 21. For 1 second, a notification sound is generated. Next, in step S5, it is determined whether or not 10 seconds have elapsed from the operation of the start / stop switch S1, but if it has not elapsed, the process proceeds to step S20 and subsequent steps. That is, when the upper case 31 has not been closed yet, the process returns from step S20 to steps S45, S55, S62, S50, S51 and back to step S1. While such an operation is repeated several times, the user of the present embodiment closes the upper case 31 for convenience of carrying during exercise, but thereafter, the above steps S1 to S5 are performed. After the processing, the process proceeds to step S20, where it is detected that the output of the optical sensor 14 is at the L level, and the process proceeds to step S21 and subsequent steps. That is, in step S21, the value of the open state flag FT is 1 instead of 0, and it is determined that the upper case 31 was open until immediately before, and then the value of the open state flag FT is set to 0 in step S41. It is remembered that the case 31 is closed. Next, in step S42, the display operation in the second display unit 20 is stopped and the display operation in the first display unit drive circuit 17 is started, and the process proceeds to step S29 to determine whether the value of the first display unit mode register UM is 0. , 0, the process proceeds to step S31 and the time counting circuit 8
The current time from is displayed on the first liquid crystal display panel 32a of the first display unit 18, but when it is 1, the timer time set in the subtraction timer 12 is displayed on the first liquid crystal display panel 32a. After that, the process returns to step S1. After that, steps S1 to S5, S20 to S22, S29 to S3
The process of 1 and S1 is repeated.

The above 10 seconds elapse while the above operation is repeated. In that case, the fact is detected in step S5, and the process proceeds to step S6.
Then, in step S6, the timer time is 0 hour 00.
After confirming that the count is not reached, the process proceeds to step S7, and the fact that the measurement is started with the value of the measurement flag FS set to 1 is stored, and the RS flip-flop 10 is set to the set state in step S8 to be measured by the subtraction timer 12. Actually start. Next, in step S9, 1 is set in the first display unit mode register UM to automatically set the first timer mode, and even if the current time is displayed on the first liquid crystal display panel 32a of the first display unit 18, it is forced. The timer time display. In the next step S10, the value of the standby flag FA is set to 0, and the fact that the standby for 10 seconds is completed is stored. Then, in step S11, the above-mentioned waiting for 10 seconds is completed, and the fact that the subtraction timer 12 has actually started measuring the remaining time is notified, and a sound is issued to prompt the user to start exercise (for example, jogging start). A signal is sent to the device 21 to generate a start sound (that is, the user starts the exercise in accordance with the start sound, so that the subtraction timer 12 can start measuring the remaining time and the start of the exercise). .

After the exercise of the user and the measurement of the remaining time by the subtraction timer 12 are started as described above, the processes of steps S20 to S22, S29 and S30 are executed and the process returns to step S1. Then, in step S1, the value of the in-measuring flag FS is already 1, and the subtraction timer 1
It is determined that the measurement of the remaining time by 2 is started, and in step S15, it is determined whether or not the timer time of the subtraction timer 12, that is, the remaining time is 0, and when it is not 0, step S20 ~ S22, S29,
The operation of returning to step S1 via S30 is repeated.

The above is the operation when the exercise is started at the end of the waiting time of 10 seconds, but the exercise is started before the end of the waiting time and the counting operation of the subtraction timer 12 is performed in accordance with this. To forcibly start the operation, operate the start / stop switch S1. At this time, the operation is detected in step S23, it is confirmed in step S26 that the value of the measuring flag FS is 0, and it is further determined in step S35 that the timer time of the subtraction timer 12 is not 0 hour 00 minute. Then, in step S36, the value of the measuring flag FS is set to 1, the RS flip-flop 10 is set to the set state in step S37, the subtraction timer 12 is caused to start measuring the remaining time, and the value of the first display mode register UM is set to 1. In the 1-timer mode, the value of the standby flag FA is set to 0 in step S39 to suspend the standby, the process returns to step S1 through steps S29 and S30, and the same operation as that described above (steps S1, S15, S20-
S22, S29, S30, S31).

As described above, while exercising while measuring the remaining time by the subtraction timer 12,
When it is desired to check the current time, the switch S2 is operated. At this time, the operation is detected in step S24, and the value of the first display mode register UM is changed from 1 to 0 in step S25, that is, the first time display mode is set.
In step 29, it is confirmed that the value of the first display mode register UM is already 0, and in step S31 the current time from the time counting circuit 8 is displayed on the first liquid crystal display panel 32a, and in step S1. Return. Further, in order to return from this state to the display state of the remaining time of the subtraction timer 12, that is, the first timer mode, the switch S2 is operated again, but also in this case, the operation is detected in step S24, and step S25 is executed.
Then, the value of the first display mode register UM is set to 1, and the first liquid crystal display panel 3 is processed in step S30 through step S29.
The remaining time of the subtraction timer 12 is displayed on 2a, and the process returns to step S1.

Further, after the subtraction timer 12 starts counting the remaining time as described above and before the remaining time becomes 0,
To forcibly stop this counting, the start / stop switch S1 is operated. At this time, the operation is performed in step S2
3, the value of the measuring flag FS is 1 instead of 0 in step S26, and it is confirmed that the counting is currently being performed, and then the value of the measuring flag FS is set in step S27. It is set to 0 and the fact that the above counting is stopped is stored. Next, at step S28, the RS flip-flop 1
The count by the subtraction timer 12 is stopped by setting 0 to the reset state, and the remaining time at that time is displayed on the first liquid crystal display panel 32a of the first display unit 18 in step S30 after step S29, and the process returns to step S1. .

The measurement of the remaining time by the subtraction timer 12 is continued without interrupting the measurement as described above, and when the remaining time becomes 0, it is detected in step S15, and in the next step S16. The value of the in-measuring flag FS is set to 0 and the fact that the measurement is stopped is stored. Then, in step S17, the RS flip-flop 10 is reset and the subtraction timer 12 is set.
Measurement operation is stopped, and in step S18, the alarm device 21
Is sent to generate a notification sound indicating that the remaining time of the subtraction timer 12 has reached 0, but the user recognizes that the time corresponding to the timer time set in the subtraction timer 12 has elapsed. , Will stop the exercise.

(C) When the measurement start switch is operated after the upper case 31 is closed: When the upper case 31 is closed after the timer time is set in the subtraction timer 12 as described above, it is set in step S20. In step S21, it is determined that the value of the open state flag FT is not 0. Then, in step S41, the value of the open state flag FT is set to 0, and the upper case 31 is closed. The display is started by the first display unit 18, and the display by the second display unit 20 is stopped in step S42. Then, the process proceeds to steps S29 to S31, and the first display mode register UM is operated according to the value of the first display mode register UM.
The timer time or the current time is displayed on the first liquid crystal display panel 32a of the display unit 18, and the process returns to step S1.

In 42b, the value of the in-measuring flag FS is set to 1 and the start of the measurement by the subtraction timer 12 is stored, and the next step S42c
Then, the value of the standby flag FA is returned from 1 to 0, and it is stored that the standby state is finished.
6, the RS flip-flop 10 is set to the set state in step S37, the first timer mode is set in step S38, and the first timer mode is set in step S30 via step S29.
The remaining time of the subtraction timer 12 is displayed on the liquid crystal display panel 32a, and the process returns to step S1. After that, steps S15, S20 to S22, S29, and S3 are performed as in the first embodiment.
0, S1 operation is repeated until the remaining time of the subtraction timer 12 becomes 0
Will be waiting for.

As described above, in this embodiment, the upper case 31
When the start / stop switch S1 is operated to instruct the start of the measurement by the subtraction timer 12 before closing, the measurement by the subtraction timer 12 is actually started after the upper case 31 is closed. Therefore, in accordance with the fact that the user closes the upper case 31,
All you have to do is start exercise.

As described above, the operation when the remaining time of the subtraction timer 12 becomes 0 after the measurement by the subtraction timer 12 is started is the same as that of the first embodiment as described above. It is similar.

The present invention is not limited to the above embodiments, and various modifications and applications are possible without departing from the scope of the present invention. For example, in both the first and second embodiments, when the start / stop switch S1 is operated with the upper case 31 open, the upper case 31 is then closed and the subtraction timer function is used. Of course, this is not limited to the subtraction timer function and may be a stopwatch function.
