FIG.

Next, the operation of the timepiece of this embodiment will be explained.

However, the circuit shown in FIG. 2 operates with positive logic, and when it is simply written as H, it means that the logic level is in the H state, and when it is simply written as L, it means that the logic level is in the H state. Each indicates that the logic level is in the L state.

The watch of this embodiment is configured to enter the time display mode when both FF 21 and FF 22 constituting the above-mentioned functional mode selection circuit 11 are in the reset state.

Therefore, in this state, among the AND circuits 23 to 26, only the output of the AND circuit 23 is in the H state, and as a result, the display selection circuit 13 selects the display device 1.
5 is controlled to be in the time display mode as shown in FIG. 3a.

In this state, the AND circuit 34 of the AND circuits 34 to 37 constituting the correction control circuit 12 described above is
Since only ? is in the ON state, the correction digit selection switch? By operating the switch S3 and the correction signal manual switch S4, time corrections such as hour correction, minute correction, and second zero setting can be performed.

Next, from the above-mentioned time display mode, select the function selection switch S.
Once 1 is closed, 1 formed by the differentiating circuit 20
FF21 is in the set state and FF22 is in the set state by
is in a reset state.

As a result, among AND circuits 23 to 26, AND circuit 2
4 becomes the H state, and the display device 15 enters the calendar display mode as shown in FIG.

In this state, only the AND circuit 34 among the AND circuits 34 to 37 is in the ON state, so that if the correction digit selection switch S3 and the correction signal input switch S4 are operated, the month of the calendar can be changed. You can make corrections and date corrections.

Furthermore, when the function selection switch S1 is closed again from the above-mentioned calendar display mode, the FF 21 goes into the reset state and the FF 22 goes into the set state. As a result, only the AND circuit 24 among the AND circuits 23 to 26 goes into the H state, and the clock Shift to chronograph mode.

In this state, among the AND circuits 34 to 3γ, A
Since only the ND circuit 36 is in the ON state, when the correction digit selection switch S3 is closed, one pulse formed by the differentiating circuit 32 is sent to the FF 43 via the AND circuit 36 and the OR circuit 42. It will be input to the set terminal S.

As a result, the FF 43 is set, the AND circuit 45 is turned on, and the 100 Hz chronograph signal Φ generated by the chronograph signal forming circuit 8 is generated via the AND circuit 45.

is input to the chronograph system counter 6, and the counter 6 starts counting, and the chronograph starts.

That is, the correction digit selection switch S3 is configured to also function as a chronograph start switch, while the FF 43 serves as a counting operation control means for controlling the start of counting operation of the chronograph counter 6. It fulfills the following.

Furthermore, when the correction signal manual switch S4 is closed from the chronograph start state, one pulse formed by the differentiating circuit 33 is manually applied to the reset terminal R of the FF 43, so the FF 43 enters the reset state and the AND circuit 44 is activated. , is in the ON state, and the AND circuit 45 is in the OF state.
It becomes F state.

As a result, the chronograph signal ΦC is no longer manually applied to the chronograph system counter 6, and the chronograph is in a stopped state.

Also, from this state, once again change the correction signal input switch S4.
When the chronograph system counter 6 is closed, one pulse formed by the differentiating circuit 33 is sent to the reset terminal 6r provided in the chronograph system counter 6 via the AND circuit 44 which is in the ON state.
3C, the chronograph is in the zero set state and the display 15 is in the state shown in FIG. 3C.

That is, the correction signal manual switch S4 is configured to double as a chronograph stop switch and a zero set switch.

Also, from the aforementioned chronograph mode, if you close the function selection switch S1 again, FF21 and FF
22 are both in the set state, AND circuits 23 to 26
Of these, only the AND circuit 26 is in the H state.

As a result, the time becomes the alarm setting mode, and the display device 15 enters the alarm setting time display state, as shown in FIG. 3e.

In this state, among the AND circuits 34 to 3γ, A
Since only the ND circuit 37 is in the H state, the alarm time can be set by appropriately operating the correction digit selection switch S3 and the correction signal manual switch S4.

On the other hand, in this alarm setting mode, since the AND circuit 26 is in the H state as described above, the AND circuit 28 is also in the ON state.

Therefore, in this state, when the program alarm setting switch S2 is closed one delay, one pulse formed by the differentiating circuit 27 is manually inputted to the toggle terminal T of the FF 29 via the AND circuit 28. Become,
The FF 29 alternately repeats a set state and a reset state.

When the FF 29 is in the reset state, the clock corresponds to a normal alarm setting state and can be used in the same manner as a conventional alarm clock.

On the other hand, if the FF29 is selected to be set by the program alarm setting switch S2,
The clock enters the program alarm setting state and display device 1
5 is in a state as shown in FIG. 3f.

That is, the program alarm setting switches S2 and F
F29 etc. are provided as an additional function operation mode setting means for selectively setting an additional function continuous operation mode (program alarm) in which the operation of the chronograph is triggered according to the operation of the alarm function section, Further, the second display section 15a of the display device 15 is configured to also serve as an identification display section for identifying the setting state of the additional function operation mode.

In addition, if a program alarm is set, the F
Since F29 is in the set state, the AND circuit 30
is kept in the ON state.

Therefore, when the clock time coincides with the alarm setting time, the alarm coincidence signal Φ outputted from the minus number output circuit 8 is input to the differentiation circuit 31 via the AND circuit 30.

As a result, one pulse formed by the differentiating circuit 31 is input to the reset terminal R of the FF 21 and the set terminal S of the FF 22, and is also input to the FF 43 via the OR circuit 42 in the chronograph control circuit 40. It will also be input to the set terminal S.

That is, the AND circuit 30 applies the function of controlling the FF 43 and the function of controlling the FF 43 to the coincidence signal φA only when the additional function continuous operation mode (program alarm) is set.
This is provided as a manual control means to provide a function of forcibly shifting the F21 and F22 to chronograph mode.

Therefore, at the same time as the above-mentioned alarm coincidence signal Φ rises, FF21 goes into the reset state and FF22 goes into the set state, the watch is forcibly shifted to the chronograph mode, and FF43 goes into the set state, so that the chronograph also goes into the set state. At the same time, it becomes a start state.

In other words, the watch of this embodiment is configured such that when the program alarm function is set, the watch shifts to the chronograph mode and starts the chronograph at the same time as the alarm time arrives. ing.

Therefore, if you set the alarm time to the start time of a sports match such as soccer in the program alarm setting mode, you will be able to know the start time of the match by the sound of the piezoelectric buzzer 10, and at the same time, you will be able to know the start time of the match. Since the elapsed time can be measured without any additional operations, it can be used very effectively when refereeing matches, etc.

In addition, when a car race, marathon, etc. starts at a predetermined time, or when a scientist starts an experiment, it is necessary to indicate the start time with a buzzer and measure the elapsed time. can be used effectively.

Further, if the function selection switch S1 is closed one more time from the alarm setting mode, both FF21 and FF22 are reset, and the watch returns to the time display mode.

The watch of this embodiment has only one alarm memory, but if it has multiple alarm memories, only one of them can be set to the program alarm function. may be configured.

For example, if you have two alarm modes: daily alarm and temporary alarm,
It is sufficient to configure the system so that only the alarm can be set to the program alarm function.

Furthermore, in the watch of this embodiment, the program alarm setting switch S2 also serves as a switch for lighting the lamp LA for illuminating the display device 15, but the switch S2 is also used to stop the buzzer sound. It is also possible to use it as a switch.

Furthermore, in the above embodiment, as shown in FIGS. 3a-f, the seconds display section 15a of the display device 15 also serves as a selection confirmation display for each function mode, etc. For example, there is no need to provide a separate display section to display the function name.

As described above, according to the present invention, the alarm function section provided as the first additional function section and the elapsed time measurement function section such as a chronograph or timer provided as the second additional function section are independently provided. Of course, by using the plurality of additional functions described above in combination in a systematic manner, it is possible to provide a multifunctional electronic timepiece with even higher utility value.
