Description

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

Conventionally, there are 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 turn on only when you want to see the display, especially mobile watches. well known.

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 certain period of time, the hours and minutes will be displayed. ” time display.

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 automatically continuing the display state shown in Figure 2 for a certain 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 considering the battery life statistically and considering the automatic continuation time that is 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, and by setting the external operating member, the display lighting or display switching state is automatically continued for a certain period of time. Provided is an all-electronic timepiece, characterized in that the automatic duration time is changed in accordance with the length of time for which the external operating member is held set. to do (has two purposes)

This will be explained below with reference to the drawings.

Figure 3 shows the 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 is a decoder circuit, 5 is a display gate circuit, 6 is a display drive circuit, 7 is a charging display device made of a light emitting diode or liquid crystal, etc., 8 is a display control circuit including a timer circuit, and 9 is an external operation means.

FIG. 4 shows an embodiment of a circuit block constituting the display control circuit 8 and external operation means 9 shown in FIG. 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 it is synchronized with the frequency-divided signal. The signal is waveform-shaped and transmitted to the display control circuit 8 via the line 17.

This display control circuit 8 includes a gate circuit I 23, a counting circuit 11. It is composed of a decoder circuit 12, a gate circuit I113, and a timer circuit 14, and the gate circuit I23 is
The gate is opened and closed by the signal transmitted through the line 17, and the divided signal transmitted from the frequency dividing circuit 2 through the line 21d is transmitted to the next one through the line 24 depending on the opening and closing of the gate. It may or may not be transmitted to the counting circuit 11.

The counting circuit 11 counts the number of signals of the frequency-divided signal that is transmitted, and transmits a signal corresponding to the counted content to the decoder circuit 12 via the line 18. The gate circuit 13 receives several frequency-divided signals with different frequencies from the frequency divider circuit 2 via the line 21 and opens a specific gate of the gate circuit 13. and the decoder circuit 12
Through a particular gate opened by the output signal of
transmitted to.

Further, when the line 24 becomes H, this timer circuit 14 is set, and the output line 80 from this 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 the line 80 becomes L. At the same time, 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 operation member 15, the output line 80 of the timer circuit 14 becomes H, and until it becomes L again, the AND gate 26 of the display gate circuit 5 is opened, and the data is transmitted from the decoder circuit 4 via the line 40. The incoming segment signal is transmitted to the display drive circuit 6 via the line 50, and the display is turned on.

Moreover, while the external operating member 15 is set and held, the gate of the gate circuit I23 is open, and during that time the frequency-divided signal is transmitted to the counting circuit 11 and counted. Since the frequencies of the divided signals transmitted to the timer circuit 14 are different, the output line 80 of the timer circuit 14
The duration of the H state is different, and it is possible to create a continuous lighting state of the display corresponding to the length of the set holding time.

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 signal of the circuit of FIG. 5, and when the external operation member 15 is set and the signal 61 of FIG. A signal 63 synchronized with the frequency-divided signal 61 is generated on the output line 17 of the DATE-TYPE flip-flop forming the circuit 10.

When this signal 63 is H, the gate of the gate circuit I 23 is opened and a signal 66 appears on the output line 24 of this gate circuit I 23.

At this time, the signals 64 and 65 are sent to the flip-flops FF1 . Each output line 18- of FF2
a, the signal appearing at 18-b.

As shown in FIG. 5, if the frequency of the signal f4 inputted to the gate circuit I 23 via the line 21-d is set to two, the length of the setting holding time of the external operating member 15 will be 0.5 seconds. In the following cases, the output line 18-a of flip-flop FF1
is H, the flip-flop line 18-b is L, and when the time is less than 1 second, the output line 18-a of the flip-flop FF1 is L, and the flip-flop FF2 is low.
When the output line 18-b is H, and 1.5 seconds or less, both output lines 18-a and 18-b are H.

Open/close states of gates 27, 28, 29 of decoder circuit 12 for each set holding time, gate circuit I11
FIG. 7 shows the open/closed states of the gates 31, 32, and 33, the signal appearing on the line 25, and the display lighting time at that time.

I would like to add some additional explanation regarding the display lighting duration time.
From the time the timer circuit 14 is set, fl.

The time it takes for the output line 80 of the timer circuit to become L after the f2 and f3 signals are input manually is 1 second and 2 seconds, respectively.
seconds and 4 seconds, but when the fz' and f3 signals are input, the set holding time from the start of setting of the external operating member 15 is added, so the time becomes as shown in Fig. 7. There is.

That is, when the setting holding time of the external operating member is 0.5 seconds or less, the f1 signal is input to the timer circuit 14, but when the setting holding time exceeds 0.5 seconds, the signal 66 becomes H again. Flip-flop FF of timer circuit 14
3. FF4. FF5. Set all FF6 and press f
The display control circuit 8 is configured such that when the 2 signal is input and the set holding time further exceeds 1 second, the signal 66 becomes H again, the timer circuit 14 is set, and the f3 signal is input. Therefore, the display lighting duration time is like this.

Also, if the display gate circuit 5 in FIG. 4 is configured as shown in FIG. 8, when the line 80 is L, the hour and minute segment signals are passed through the line 40-b, and when the line 80 is H, the hour and minute segment signals are sent through the line 40-b. , line 40
-b, the month and day segment signals are transmitted to the display drive circuit 6 through the line 50, respectively, and the display changes from hour to month and day from L to H on line 80, so this is the case. In this configuration, the duration of the display switching state is changed in accordance with the set holding time of the external operating member 15.

In the case of an all-electronic portable watch with a light emitting diode display, the display becomes difficult to read in bright surroundings, so it may be possible to lengthen the setting hold time and the display lighting duration.

On the other hand, with all-electronic mobile watches with liquid crystal or electrochromic displays, 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.

Figure 9 shows another embodiment of the present invention, the drawings are shown in Figures 3 and 4.
Based on the figure, the gate circuit I23-a shown in FIG. 5 is replaced with a gate circuit I23-a, and an operating means 34 for controlling the gate circuit I23-a is provided.

Under normal conditions, this switch 34 is open, so
Gates 1 to 35 open, gate 36 closes, and at this time the fifth gate
It works exactly the same as the figure.

Therefore, the lighting duration of the display changes depending on the setting holding time of the external operating member 15, but when this switch 34 is closed, the gate '35 is closed and the gate 136 is opened, so the external operating member 15 The signal from the 15 set operations is
The number signal is transmitted directly to the line 24 via the Noah gate 37, and the number signal generated by the set operation of the external operating member 15 is directly transmitted to the counting circuit 11. Since the information is transmitted to the timer circuit 14, the lighting duration of the display changes in accordance with the number of times the external operation member 15 is set.

With this configuration, the user can freely select and control the display lighting duration time using the external operating member 15 by switching the operating means 34.

Alternatively, the watch store or manufacturer can determine whether the operation method is based on the set holding time or the number of times the watch is set.

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 and the user's time and place of use, making it easier to use. At the same time, it is now possible to perform displays that match the characteristics of the display elements for emitting and receiving light.

Also, f,, f2. The illustrative example of f3 in FIG. 7 is just one example, and the numerical values are not limited thereto.
