Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a telephone number storage device having a function of storing names and their telephone numbers.

[Conventional technology]

Conventional electronic telephone number storage devices can only store multiple names and their telephone numbers, and when a desired name is entered, the telephone number corresponding to the name is displayed.

[Problems with conventional technology]

However, with the conventional devices mentioned above, if you make a call overseas without checking the local time,
There was a fear that I would cause trouble to the other party, or that I would be absent. Furthermore, even if the above device is incorporated into an electronic watch with a world time function, it is cumbersome to operate to check the local time, and it is difficult to confirm the local time in which time zone the local time is located. There was also the trouble of having to check the details one after another.

[Purpose of invention]

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, it is an object of the present invention to provide a telephone number storage device that allows you to instantly know the local time even when calling overseas.

[Key points of the idea]

In order to achieve the above object, the present invention enables place name data such as city or country name to be stored for each telephone number data, and allows local time to be displayed based on the place name data.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is an external view of an electronic wristwatch to which an embodiment of the present invention is applied. In the figure, a watch main body 1 includes a display section 2 consisting of a liquid crystal display or the like, and various key switches _S1 to _S5 .

FIG. 1 is a block diagram showing the configuration of the internal circuit of the electronic wristwatch, and FIG. 3 is a diagram showing various display examples on the display section 2 in FIG. 1. Second
In the figure, display section 2 and key switches S ₁ to _{S 5}
is the same as shown in FIG.

The key switch _S1 is a switch for changing the display mode, and the output state of the flip-flop 3 is changed according to whether it is turned on or off.
When the output of flip-flop 3 is at H (high) level, gate _g1 is open. The high frequency clock signal output from the oscillator 4 is frequency-divided by the frequency divider circuit 5, and further converted into time data such as hours, minutes, seconds, etc. by the counter circuit 6, and this time data is sent to the gate _g1. The image is displayed on the display section 2 by the display drive section 7 via the display drive section 7.

If you operate key switch _S1 again while the flip-flop 3 output is at H level, the output will go to L level.
(low) level, and the Q output becomes H level. Then, gate _g1 closes and gate _g2 opens via AND circuit _A1 , and the telephone number data stored in RAM 8 is read out from the address specified by RAM control section 9, and gate g2 is opened via AND circuit A1. ₂ is displayed on the display section 2 by the display drive section 7. That is, by operating the key switch _S1 , the display mode of the display unit 2 changes to the timetable mode _m1.
This will switch to the phone number data display mode _m2 .

The RAM 8 is composed of a name storage section 8a, a telephone number storage section 8b, a place name code storage section 8c, etc., and each data is read and written by address designation from the RAM control section 9. It's becoming like that.

Key switch _S2 is a step switch, and when it is operated while the Q output of flip-flop 3 is at H level, the number of operations is determined by the AND circuit.
It is counted by the RAM control unit 9 via _A2 , and addresses of the RAM 8 are sequentially specified according to the count value. Then, the telephone number data stored in the area specified by the address is displayed on the display section 2. That is, as shown in FIG. 3, in the telephone number data display mode _m2 ,
By sequentially operating the key switch _S2 , a plurality of telephone number data stored in the RAM 8 are sequentially switched and displayed.

Key switches S ₄ and S ₅ are switches for setting and changing data in the RAM 8. With the Q output of flip-flop 3 at H level, after specifying the desired area of RAM 8 with key switch S ₂ , the key switches S ₄ and S ₅ assign a name to the above area of RAM 8 via AND circuits A ₃ and A ₄ . ,
You can write your phone number and place name code. The place name code is a numerical code provided in advance corresponding to the name of each place, and is set, for example, as "0" for Tokyo, "1" for Paris, and "2" for New York.

Key switch _S3 is a switch for displaying the local time, and when it is turned on, the output of inverter circuit _I1 will be at L level only while it is on, and at the same time, the output of AND circuit _A1 will also be at L level. So gate g ₂ closes. Then, the telephone number data being read out from the RAM 8 is stopped at the gate _g2 , and instead, the place name code corresponding to the above telephone number is read out from a predetermined address in the place name code storage section 8c and sent to the time difference calculation section 10. Sent. The time difference calculation unit 10 stores the time difference between the local time and the domestic time corresponding to each name code, and adds (or subtracts) the time difference to the current time obtained by the clock counting circuit 6. , the local time is calculated. This local time is displayed on the display section 2 by the display drive section 7 via the gate _g3 , together with the place name. That is, as shown in Figure 3,
If the key switch _S3 is operated in the telephone number data display mode _m2 , the mode switches to the local time display mode _m3 only during that operation.

As described above, in this embodiment, in addition to the name and telephone number, the place name and local time are also displayed, so that the user can make a call at the appropriate local time. For example, in the example in Figure 3, the domestic time is 10 a.m.
It is 50 minutes, which is the appropriate time to call "AOKI" in "TOKYO", but "PARIS"
If you try to call "BILLY" in , you will immediately know that the local time is 2:50 a.m. in the middle of the night. Therefore, it can be easily determined that making a call now would be a great nuisance to the other party, and the user will not make a mistake in making a call.

In addition, instead of entering the place name code into RAM8, you may enter the above time difference directly using the keypad.
If the time difference calculation unit 10 stores the time difference of each place in advance as in the above embodiment, key operations will be easier.

Furthermore, the present invention is applicable not only to the above-mentioned electronic wristwatches, but also to various electronic devices such as small electronic calculators, and can even be manufactured as a dedicated device with a telephone number storage function. You can also do that.

[Effects of the invention] As explained above, according to the invention, even when making a call overseas, the local time can be immediately known, and therefore it is possible to avoid accidentally calling at an inappropriate local time. You no longer have to worry about losing money.
