[Detailed description of the invention] This invention connects a timer circuit to an external operating member for controlling display lighting or display switching, and automatically controls display lighting or display switching for a fixed period of time by setting the external operating member. Concerning an all-electronic clock configured to last.

Conventionally, liquid crystal display watches that switch between displaying multiple pieces of information on the same display, and light-emitting diode display watches that are always off and only turn on when you want to see the display by external operation, especially mobile watches, are well known. It is being

Figures 1 and 2 show display examples of a liquid crystal display clock and a light emitting diode display clock, respectively. '', and when externally operated, the calendar time of ``month'' and ``day'' will be displayed as shown in Figure 1, and after automatically continuing the display state of Figure 1 for a fixed period of time, The time display returns to "minutes".

The light emitting diode display clock shown in Fig. 2 is normally in the display off state as shown in Fig. 2, but when operated externally, it displays the time in hours and minutes as shown in Fig. 2. After the display state shown in Figure 2 is automatically continued for one fixed period of time, the display turns off.

In such watches, a timer circuit is connected to an external operating member, and the timer circuit realizes automatic continuation and restoration of the display.

By the way, in conventional watches like this, the time of the timer circuit is set in advance to a constant value, taking into consideration the battery life and the automatic continuation time that is statistically considered to be the most appropriate.
The circuit has been designed and manufactured.

For this reason, the timer time cannot be changed depending on the user or the user's usage conditions (time, location).

Therefore, in the present invention, a timer circuit is connected to an external operating member for controlling display lighting or display switching, so that the display lighting or display switching state is automatically continued for one fixed period of time by setting the external operating member. An object of the present invention is to provide an all-electronic timepiece characterized in that the automatic duration time is changed in accordance with the number of times the external operating member is set. .

This will be explained below with reference to the drawings.

Figure 3 is a basic configuration diagram of the all-electronic watch according to the present invention.
This is an example.

1 is a reference signal generation circuit 2 is a frequency dividing circuit, 3 is a counting circuit, 4
5 is a decoder circuit, 5 is a display gate circuit, 6 is a display drive circuit, 7 is a photoelectric display device made of a light emitting diode or liquid crystal, etc., 8 is a surface area control circuit including a timer circuit, and 9 is external operation means.

FIG. 4 shows an embodiment of a circuit block configuring the display control circuit 8 and external operating means 9 shown in FIG. 1. The external operating means 9 is composed of an external operating member 15 and a waveform shaping circuit 10. Here, the signal created by the set operation of the external operating member 15 is transmitted from the line 16 to the waveform shaping circuit 10, and from the frequency dividing circuit 2 via the line 22, where the signal is waveform-shaped into a signal synchronized with the frequency-divided signal. It is transmitted to the display control circuit 8 via line 17.

This display control circuit 8 includes a counting circuit 11. Decoder circuit 1
2. It is composed of a gate circuit 13 and a timer circuit 14, and the counting circuit 11 counts the number of times the external operating member 15 is set based on the signal transmitted via the line 17, and sends an output signal corresponding to the number of sets to the line. 18 to the decoder circuit 12, and the decoder circuit 12 transmits a signal corresponding to the output signal via the line 19 to the gate circuit 13.
Open certain gates.

Several frequency-divided signals with different frequencies are transmitted from the frequency divider circuit 2 to this gate circuit 13 via a line 21, and a frequency-divided signal of a specific frequency is transmitted through a specific gate opened by the output signal of the coder circuit 12. It is transmitted to the timer circuit 14 via line 25.

When a set signal from the external operating member 15 is first transmitted via the line 17, the timer circuit 14 enters the set state, and the output line 80 from the timer circuit 14 becomes H.

A signal of a specific frequency is transmitted to this timer circuit 14 from a line 25, and after a certain period of time inversely proportional to the frequency of the transmitted signal, the output line 80 of the timer circuit 14 becomes L, and as the line 80 becomes L, , the counting circuit 11 is also reset, all gates of the gate circuit 13 are closed, and the frequency-divided signal is not transmitted to the timer circuit 14, so the output line 80 of the timer circuit 14 remains fixed at L.

By this setting operation of the external operating member 15, the output line 80 of the timer circuit 14 changes from H to L again. The segment signal is transmitted to the display drive circuit 6 via line 50 and the display is lit.

Moreover, since the frequency of the divided signal transmitted to the timer circuit 14 differs depending on the number of times the external operating member 15 is set, the duration of the H state of the output line 80 of the timer circuit 14 differs, and the display corresponding to the number of times the external operation member 15 is set is lit. It is now possible to create a continuous state.

FIG. 5 is a specific circuit example of the circuit block diagram shown in FIG. 4.

In a normal state, the switch of the external operation member 15 is open, and when set, it closes.

The timing chart of FIG. 6 shows the signals of the circuit of FIG. 5, and when the external operating member 15 is set and the signal 61 of FIG. A signal 63 synchronized with the frequency division signal 61 is sent to the output line 17 of the DATA-TYPE flip-flop constituting 10.
occurs.

At this time, flip-flops FF3 . FF4. FF5. FF6 is set and each output becomes H.

(1) Flip-flop FF1 constituting the counting circuit 11
．． The signal appearing on each output line of FF2 is signal 64
When the signal 65 is set and the number of times the external operating member 15 is set is 1, the flip-flop line 18-a becomes H, and the flip-flop force line 18-b
is low, so only the output line 19-a of the AND gate 27 of the coder circuit 12 becomes H, opening only the AND gate 31 of the gate circuit 13, and the f1 signal transmitted from the frequency dividing circuit 2 via the line 21-a is Timer circuit 14 via line 25
is transmitted to flip-flops FF3, FF4, FF
5. Change the output contents of FF6.

When the output line 80 of the flip-flop FF6 becomes L after one fixed time, the flip-flops FF1 and FF2 of the counting circuit 11
Both are reset, and the output lines 18a and 18-b both become L, so the ant-gauge of the coder circuit 12
Output lines 19-a, 19b, 1 of F27, 28, 29
9-C are all L, and the ant gate of the gate circuit 13
)-31, 32, and 33 are all closed, and the divided signals f1, f2, f3 are not transmitted to the timer circuit 14 via the line 25.

By the way, when the f1 signal is transmitted to the timer circuit 14 by the first setting operation of the external operating member 15, and the second setting operation is performed before the flip-flop of the timer circuit 14 is turned off, the timer circuit 14 is set. flip flop.

FF3, FF4, FF5, and FF6 are all set, and the flip-flops FF1 and FF6 of the counting circuit 11 are set.
The output lines 18-a and 18-b of the FF2 become L and 'H, and the output line 19-a of the AND gate 27 of the decoder circuit 12 becomes L, and the AND gate 2
Only the output line 19-b of No. 8 becomes H, and the AND gate 32 of the gate circuit 13 is opened.

As a result, the f2 signal is transmitted from the frequency dividing circuit 2 to the timer circuit 14 via the line 21-b, and the output line 80 of the flip-flop FF6 is changed from H to L again after one fixed period of time.

If the f2 signal, which has twice the frequency of the f1 signal, is transmitted to this timer circuit 14, the flip-flop FF3. FF4. FF5. The time from when FF6 is set until it becomes a flip-flop is doubled.

In addition, this f2 signal controls the external operation member 15 from the timer circuit 1.
4, and the third set operation is performed until the flip-flop line 80 changes from H to L. This time, the f3 signal is transmitted to the timer circuit 14, and the f3 signal is again inversely proportional to the frequency of the f3 signal. The output line 80 of the flip-flop FF6 continues to be in the H state.

With the above configuration, for example, f. , f2
, f3 are set in advance as 4f1 = 2f2 = f3, the display lighting time will be changed depending on the number of times the external operation member 15 is set. It is possible to perform control operations such as lighting twice as many times, or lighting twice as many times as three times.

Further, if the display gate circuit 5 in FIG. 4 is configured as shown in FIG. 7, when the line 80 is L, when the line 40-b is passed through,
When the minute segment signal is H on the line 80, the month and day segment signals are transmitted through the line 40-a to the display drive circuit 6 through the line 50, respectively. Therefore, in such a configuration, the duration of the display switching state is changed in accordance with the number of times the external operation member 15 is set.

For this reason, in the case of an all-electronic watch with a light emitting diode display, the display becomes difficult to read in bright surroundings.
It is conceivable to set a large number of external operation members 15 within one fixed period of time to lengthen the lighting duration of the display.

On the other hand, for all-electronic mobile watches with liquid crystal display or electromism display, the display becomes difficult to read in dark surroundings, so you may want to set the automatic continuation time of the switched display to a longer value.

As described above, the all-electronic watch according to the present invention can change the automatic duration of the above-mentioned display lighting and display switching depending on the user, time of use, and place of use, making it easier to use. Displays can be made that match the characteristics of the display elements for emitting and receiving light.

FIG. 8 is a partially improved view of the all-electronic timepiece according to the present invention shown in FIGS. When the output line 80 of the timer circuit 14 becomes H, the AND gate 3
7 is opened, and the frequency division signal is transmitted to the timer circuit 36 through the line 38, and the edge line 39 is set to H for a fixed period of time, and the gate 143 is closed.

Therefore, only the set signal generated by setting the external operating member 15 within one fixed time of the timer circuit 36 is sent to the timer circuit 14.
will be transmitted to.

Since the timer circuit 36 is reset when the line 80 becomes L, the gate 43 is open at that time.

With this configuration, the lighting of the display and the switching of the display can be automatically continued regardless of whether the setting operation is early or late depending on the number of times the external operation member 15 is set.
