Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvement of electronic watches. In conventional electronic watches, one input operation did not perform two or more functions at the same time. In recent years, electronic watches have become multi-functional. This has led to increasingly complex operation methods.
The number of input switches etc. may increase. This is not preferable because it causes trouble for the user of the electronic timepiece, and also because it is subject to design constraints and the sense of luxury is impaired.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an electronic timepiece that does not require a large number of inserts, has an excellent design, is easy to operate, is inexpensive, and has multiple functions. Aimed at 0 Hereinafter, the present invention will be described in detail.

FIG. 1 is a diagram showing one embodiment of the present invention, and shows an electronic stopwatch. The striker has a function that allows three types of measurements to be performed simultaneously: standard timing 1, split timing 2, and lap timing 3.

Here, sprint timing refers to the cumulative measured time from the beginning of measurement, and lap timing refers to the section measured time.

Now, when the ■ switch 4 is operated, the standard timer 1 starts operating. While the standard timer 1 is operating, when the switch 5 is operated, two types of timer, sprint timer 2 and lamp timer 3, are displayed at the same time. These are the second
To explain using the block diagram shown in the figure, first, when input 4 is received, the counting circuit 9 starts counting by the control circuit B, and the display device 11 through the display circuit 10
The standard time is displayed. 0 When there is the first input after that, the instantaneous count value of the counting circuit 9 is latched to the latch A by the control circuit B. The count value is displayed in the display circuit 1.
The 0 displayed by the display device 11 through 0 becomes the split clock 2.

The arithmetic circuit 14 subtracts the values of the latch A and the launch B, but in the first input, the count value is not latched in the latch B. Through 10, the display device 11 displays the same value as the split timer, but this is the first lamp timer, 0.Furthermore, when manual operation is performed again, the instantaneous count value of the counting circuit 9 enters the latch A, and The value that had been in latch A until then is transferred to latch B. The count value of latch A is displayed on the display device 11 through the display circuit 10 as the second split timing. The count values of latch A and latch B are calculated. Subtraction is performed by the circuit 14, and the result is displayed on the display device 11 through the display circuit 10 as the second lap time.
Two types of time measurement are performed: split time measurement and lap time measurement, each time you input the second time, fourth time, and so on. During this time, the standard time continues to be displayed on the display device 11 from the counter circuit 9 through the display circuit 10. Fig. 6 is a diagram showing another embodiment of the present invention, in which two subtractions and additions are performed.
This is an electronic clock that displays various timer functions at the same time.

First, by input 18, subtract timer 1 at the desired time.
6 is set, and then when the operation is started by input 17, the subtraction timer 16 and addition timer 15 start subtracting and adding, respectively. When the set time arrives, notification is given by an alarm or the like. In this way, two types of timers, subtraction and addition, can be performed by one input operation, and the remaining time and elapsed time of the timer can be known at the same time. FIG. 4 shows this in block diagram form. ■According to the input, a desired timer of one hour is stored in the memory circuit 25 through the control circuit 19, and then ■When the operation is started by the input, the counting circuit 2
2 is counted or added every moment, and the value is displayed on the display device 24 through the display circuit 26. The value that is subtracted moment by moment by the arithmetic circuit 26 that subtracts the value of the counting, that is, the value of the memory 25, is also displayed on the display device 24 through the display circuit 23. At this time, the arithmetic circuit 26 When the counted value, that is, the value to be added, matches the value in the storage circuit 25, the notification circuit 27 is activated and notification is performed by the notification device 2'8.

FIG. 5 shows yet another embodiment of the present invention, which is an electronic timepiece with an alarm. FIG. 5(a) is a diagram of the basic clock mode of the electronic watch with alarm, and FIG. 5(b) is a diagram of the basic clock mode of the electronic watch with alarm.
is a diagram of an alarm time correction mode. These two people are ■
It can be switched alternately by input 62. In the basic clock mode, a basic clock 29 and a calendar 60 are displayed. In the alarm time adjustment mode, the alarm ringing time 29' and the remaining time until the alarm rings 30'
is displayed. When the alarm ringing time 29' is corrected by the input in the alarm time correction mode, the remaining time display 60' changes accordingly. now,
In the example shown in FIG. 5, the basic clock 29 is 10:15 p.m.
Since the alarm ringing time 29' is 6:30 a.m., the remaining time display 30' is 8 hours and 15 minutes. FIG. 6 shows this in block diagram form.

When there is a mode switching input 32, the display circuit 37 switches the display contents through the control circuit 33 as shown in FIGS. 5(a) and 5(b). When the alarm time adjustment mode is entered, the alarm time 29' can be set by input. This value is entered into the memory circuit 39. Also, the difference between this value and the basic clock 29 is passed through the calculation circuit 40 to calculate the remaining time 3.
It is displayed by the display device 38 through the display circuit 37 as D'. In this way, the time from the current time to the alarm sounding time can be known at the same time as the alarm sounding time. It could be easily configured as C. Although these programs or circuits cannot be uniquely determined, they can be easily configured based on the above explanation.

As described above, in the electronic watch, by one input operation, the time measurement results or calculation results at the time of the input operation are simultaneously displayed as two or more different displays, so the operation method is simple and the advantages of multi-function are achieved. Furthermore, as can be seen from the respective drawings, the structure is simple, the cost is low, and the number of inserted inserts is small, making it possible to create an excellent design, so the present invention can be said to be significant.
