Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic watch that can tell the age of a user or a specific person.

Recently, electronic watches have become more and more multi-functional. For example, some electronic watches are equipped with a calendar alarm function that allows a specific date to be set in advance and notifies the user of the arrival of the specific date by display or sound. One way to use this calendar alarm function is to set a specific person's birthday in advance and have the person be notified when the birthday has arrived. However, when a birthday is set, even if it is possible to know by notification that it is the birthday of the person, it is difficult to know how old the person is without calculating it. At the same time, I had to remember my current age, and I sometimes made mistakes in counting.

An object of the present invention is to provide an electronic timepiece that can accurately display how old a person is without having to perform calculations.

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings. In the figure, reference numeral 1 denotes an oscillator circuit for obtaining a reference clock signal.

FIGS. 2 1 and 2 show the configuration of the two-layer liquid crystal display device, FIG. 2 1 shows the configuration of the upper display section 6, and FIG. 2 2 shows the configuration of the lower display section 20. be. The two-layer liquid crystal display device is constructed by stacking three substrates at intervals and filling liquid crystal between the substrates to provide two liquid crystal layers. In the upper display section 6, a clock information display section 6a
consists of a four-digit time display arranged horizontally, a date display arranged vertically with two digits each, and a PM display. In addition, □1 to □3 display body 6
b, 6c, 6d, the date information of the date counting circuit 3b is stored in the first to third specific person information storage circuits 14 to 16 corresponding to the □1 to □3 display bodies 6b, 6c, and 6d. This is to clearly indicate that you have reached your birthday. Further, in the lower display section 20, the specific person information display section 20a includes an 8-digit name display that displays the specific person's name in alpha alphabets, the specific person's age,
It is composed of a 6-digit age and birthday display that numerically displays the date of birth, and the numeric display section 20b displays the specific person information displayed on the digital display section 20a as the first to third specific person information. It clearly indicates in which of the memory circuits 14 to 16 the data has been stored, and is constituted by a one-digit Japanese character display.

Next, the operation of the above embodiment will be explained with reference to display examples shown in FIGS. 3 and 4. usually,
Since a signal of "1" is output from the side output terminal of the binary flip-flop 9, the gate of the AND circuit 4 is released. Therefore, the counting circuit 3
The time and date information obtained by the time counting circuit 3a and the date counting circuit 3b are decoded by the decoder 5 and then sent to the clock information display section 6a of the upper display section 6. As a result, the current date and time, for example, "October 15th 3:25 a.m." as shown in FIG. , it is specified that it is in the afternoon.

Next, when the display switching switch _S1 is operated, the operation signal of this switch _S1 is applied to the one-shot circuit 7, which causes the one-shot circuit 7 to output one pulse signal. As a result, the output state of the binary flip-flop 9 is inverted, a signal of "1" is output from its Q-side output terminal, and the gates of the AND circuits 18 and 21 are released. At this time, when the content of the selection circuit 11 is set to, for example, "1", the name, age, and birthday information stored in the first specific person information storage circuit 14 is sent from the display switching control circuit 17. It is output and sent to the decoder 19 via the AND circuit 18, and after being disconnected there, it is given to the specific person information display section 20a of the lower display section 20, and the contents of the selection circuit 11 are sent to the AND circuit 21. The signal is sent to the decoder 22 via the decoder 22, where it is decoded, and then provided to the numeric display section 20b of the lower display section 20. As a result, in the lower display section 20, the digital display section 20a displays the specific person information stored in the first specific person information storage circuit 14, for example, the name "SUZUKI" as shown in FIG. 3B. ”, age “20”, birthday “October”
20th" is displayed. The number display section 20b also shows the number "1" which clearly indicates that the specific person information displayed on the specific person information display section 20a is stored in the first specific person information storage circuit 14. is displayed.

Therefore, when the selection switch _S2 is operated while the binary flip-flop 9 is set to the specific person information display mode, this switch
The operation signal of _S2 is given to the one shot circuit 8,
This one shot circuit 8 outputs one pulse signal. This pulse signal is transmitted to the AND circuit 10
The content of the selection circuit 11 is incremented through the ``1'' to ``2''. As a result, the output information of the second specific person information storage circuit 15 is sent from the display switching control circuit 17 and given to the specific person information display section 20b of the lower display section 20. Therefore, the digital display section 20b displays specific person information, for example, as shown in FIG. 3C, the name "SATO", the age "23", and the date of birth "November 10". Further, the content "2" of the selection circuit 11 is displayed on the numeric display section 20b. Similarly, when you operate selection switch _S2 , specific person information display section 2
0b displays the contents of the third specific person information storage circuit 16, and the number display section 20b displays the number "3".

For example, when the current date and time are displayed as "October 15th, 3:25 p.m.", as shown in Figure 4A, 5 days have passed since "October 15th". When "October 20th" has passed, the matching circuit 23 stores the information in the first specific person information storage unit 1.
A match between the birthday information of No. 4 and the date information of the date counting circuit 3b is detected, and a match signal _f1 is output. By outputting this coincidence signal _f1 , flip-flop 2
6 is set, and its Q side output signal becomes "1". Since this Q side output signal is applied to the □1 display of the upper display section 6, □1 is displayed on the upper display section 6 as shown in FIG. 4B. Thereby, it is notified that "October 20th", that is, today is the birthday of the person stored in the first specific person information storage circuit 14. In addition, due to the output of the coincidence signal f ₁ , the age information (20) stored in the age storage section 14b of the first specific person information storage circuit 14 becomes +
At the same time, the selection circuit 11 is preset to "1".

In this situation, the display switching switch
_S1 is operated to invert the output state of the binary flip-flop 9, and the mode is switched to a specific person information display mode in which the Q side output signal becomes "1". Since the content of the selection circuit 11 is set to "1", the content of the first specific person information storage circuit 14 is sent from the display switching control circuit 17, and after being disconnected by the decoder 19. , is sent to the specific person information display section 20 of the lower display section 20. Also, selection circuit 1
After the contents of 1 are decoded by the decoder 22,
It is sent to the number display section 20b of the lower display section 20.
As a result, the digital display section 20a of the lower display section 20 displays the name "SUZUKI", age "21", and birthday "October 20th", as shown in FIG. The number “1” is displayed on the number display section 20b.
is displayed, and it is clearly shown that the specific person information displayed on the specific person information display section 20a is stored in the first specific person information storage circuit 14. Through this display, it is possible to know that Mr. "SUZUKI" turned "21" years old today, "October 20th." When a carry signal is output from the time counting circuit 3a and the contents of the date counting circuit 3b are updated to "October 21st", the flip-flop 26 is reset by the carry signal from the time counting circuit 3a. . Therefore, in the normal timekeeping information display mode, the driving of the □1 display body 6b is stopped, and the display of □1 is turned off.

At the same time, the second specific person information storage circuit 15
"SATO"'s birthday remembered on "November 10th"
When the match signal f ₂ is reached from the match circuit 24,
is output, and the content "23" of the age storage section 15b becomes +
1 and updated to "24", and the selection circuit 1
"2" is preset to "1". Then, when the display switching switch _S1 is operated, the age "24" is displayed along with the name and birthday. The same applies when the birthday of the person stored in the third specific person information storage circuit 16 is reached. In this way, by looking at the displayed specific person information, it is possible to know how old that person is.

In the above embodiment, only the age is displayed, but the age and month, that is, the age and month, may also be displayed, and the age information is also displayed together with the name and birthday information. However, if it is possible to specify whose age the user is, there is no need to input the name, and the number of switches in the input section can be reduced.

Further, the present invention can be applied to various electronic clocks such as a desk calculator with a clock.

As explained in detail above, with this invention, if you set the birthday and age of a specific person, the age will be automatically incremented by 1 when the birthday is reached, thereby eliminating the troublesome age calculation. Even if you don't do it, you can easily know the person's exact age just by looking at the display, and there is no need to perform troublesome calculations like in the past.
