Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a keyboard-equipped watch whose time is adjusted using a numeric keypad.

The present invention provides a watch with a keyport that prevents erroneous time adjustment.

Furthermore, the present invention provides a calculator watch that is combined with a calculator.

With the development of electronic technology, calculations have become commonplace.

Calculator watches that combine such a calculator and a clock are now being considered. The calculator has a keyboard that includes tick keys and function keys, and when the time on a clock is adjusted using this keyboard, the time can be adjusted more easily than with conventional adjustment methods. However, all digits of a computer can be 0 to 9.

When correcting the time, there are digits that can be used for numbers 0 to 9 and digits that are limited to a certain number, so if you use the negative number circuit of your computer, the time that is not displayed on the clock will be displayed.
Times that are not displayed as a clock include minutes and seconds (60 to 9
9), hour and month (00.13-99), but hour is in 12-hour system, day (00.32-99), etc.

The present invention detects when a time that is not displayed on the clock is set, prevents the time from being erroneously adjusted, and notifies the user to adjust the time to the correct time.

The present invention will be explained below based on examples. FIG. 1 shows a block diagram of a computer watch using the present invention.

Negative number circuit converts to D signal, 4 is a keyboard, consisting of a numeric keypad, function keys, and a control switch.The control switch is normally in the normal state a, and each time it is pressed, it changes the calculation display and the calculation display if it is a clock display. If so, the display will switch to the clock display.

The state of this pressed control switch is b. Regulation?
When the switch is placed in the unlocked state (d), the time can be adjusted using the keyboard. 5 is a register gate, 6 is a register Xl7, and register Yl8 is a register Z.

2 timing signal system? The gate is controlled by a control switch on the keyboard 1 board 3, and when the clock is displayed, the timing signal is prohibited from being input to the arithmetic circuits (5 to 10, 12).

As a result, when a C-MOS is used in the arithmetic circuit, the power consumption is fixed at "L" or "L", so power consumption can be extremely reduced. As a result, even if a battery is used as a power source for the computer-equipped watch, the power consumption is low, making it possible to provide a computer-equipped watch that can be used for a long time. FIG. 2 is a waveform diagram of timing signals generated by a timing signal generation circuit and used in various parts of the present invention. FIG. 3 shows the digit signal Dn, calculation information and time information stored in the register.

The time information is added and held by an adder 81.

In a normal state, the operation is the same as that of a conventional circuit, so a detailed explanation will be omitted.

However, in order to make the clock display easier to understand by separating the minute and second digits and the hour and minute digits, the corresponding registers and carry signals are different. With reference to FIGS. 4, 5, and 6, the function of correcting the set time when a time that is not displayed as a clock is set using the numeric keypad will be explained.

Figure 6a shows the clock display (7:56:43) and the calculation display (7:56:43).
12345678), and either display is selected and displayed.

The process of adjusting the time from 7:56:43 to 12:34:00 will be explained.

When the control switch on the keyboard is set to the unlocked state, all digits start flashing as shown in Figure 6b.

This is because the OR gate 36 shown in FIG. 5 works and sends an all-digit flashing signal to the AND gate 49. In this state,
Digit designation key D? When the button is pressed, the seconds F.F33 is set, and the OR gate 44 sends a seconds flashing signal to the AND gate 49, causing the seconds digit to flash as shown in Figure 6C. In this state, when the number reaches 00 seconds, the numeral 16 is entered, and the AND gate 37 generates a 00 second regulation signal E, which is sent to the AND gate 24 in FIG. And gate 24 is 3
This is a gate that judges 0 seconds or more, and in this case it is 44 seconds, so it judges 30 seconds or more and sends a signal to F-F25.
F-F25 sends a reset signal to the OR gate 26 and a carry signal to the OR gate 32. The AND gate 28 inhibits second information from the shift register 18 by the OR gate 26 reset signal, so the contents of the second become 00 and are sent to the shift register 19. Further, a carry signal from the OR gate 32 causes a dot 1 to be applied to the minute digit. F-F39 is set by the l word signal of AND gate 45 in FIG. 5, and the output is sent to F-F42. Since the F-F42 beam set signal is sent to the F-Fs 33, 34, 35, 39, 4O, and 4l, the OR gate 36 moves and sends an all-digit flashing signal to the AND gate 49. The display section at this time is shown in FIG. 6d. Second correction is 10, like 00, 10...40, 50.
It can be corrected in seconds. In the state shown in FIG. 6d, when the digit designation key [F] 0 is pressed, the minute F-F34 is set, and the minute flashes as shown in FIG. 6e.

In this state, when the number 1 (3) is entered, the or gate 50 creates a number entry with the content of 3, and the AND gate 47 takes the timing and enters the or gate 2 in Figure 4.
9 inputs 3 into the 10th minute digit. An l word signal is generated by the AND gate 45 in FIG. 5, and F-F4O is set, so that the blinking signal changes and the display becomes as shown in FIG. 6f. In this state, if you enter the number on the numeric keypad (4), 4 will be input in the same way and the display will become as shown in FIG. 6g.
In this state, when the digit designation key [ is pressed, the hour F-F 35 is set, and the OR gate 36 is activated so that the hour digit blinks as shown in FIG. 6h.

In this state, if 1 is input in the same way as when entering the number key (1), the AND gate 23 in FIG. 4 becomes 17.
The time is detected and a signal is sent to F-F25, and F-F25 sends a set signal to OR gate 26, a set signal to AND gate 27, and a carry signal to OR gate 32. These signals cause the AND gate 28 to reset the 1 o'clock digit, and the OR gate 29 sets it to 1. The carry signal is 1
This is inhibited by the H correction signal G and the l word delay signal F of the AND gate 46 in FIG. The display section at this time is as shown in FIG. 6. In this state, when the numeric key (2) is entered, 2 is entered in the 1 o'clock digit in the same way, F-F4l is set, a set signal is sent to each F-F by F-F42, and the OR gate is set. 36 works and all digits flashing signal is AND gate 4
9 and the display section becomes as shown in FIG. 6j. Now that the time adjustment is complete, return the control switch to the normal state and the result will be as shown in Figure 6k. In the state shown in FIG. 6c, when keys 6 to (9) are entered, the contents of the entered keys are input to the shift register 19 through the AND gate 47 and the OR gate 29 in FIG.

Then, AND gate 21 operates and sends a signal to F-F25. F-F25 Sends set signal and carry signal. Therefore, the contents of seconds become 00. The carry signal is inhibited by the one-word delay signal F, as shown in FIG. 6d'. Further, in the state shown in FIG. 6e, when numerals 6 to 9 are entered, they are input to the shift register 19 in the same manner.

Then, AND Gate 21 works. The rest is the same as the second, and the display section looks like the one shown in FIG. 6 f'. Furthermore, in the state shown in FIG. 6h, when numeric keys 2 to (9) are entered, they are input to the shift register 19 in the same manner.

Then, AND gate 22 operates and sends a signal to F-F 25. F-F25 Sends set signal and carry signal. Therefore, the content at 10 o'clock becomes O. Since the carry signal is inhibited by the one word delay signal F, the display section becomes as shown in FIG. 6, 1'. Furthermore, in the state shown in FIG.
3) When the numbers .about.n are entered, they are input to the shift register 19 in FIG. 4 in the same manner.

Then, AND gate 23 operates and sends a signal to F-F 25. F-F25 sends a set signal, a carry signal, and a set signal. Therefore, the content of the 1 o'clock digit becomes O by the reset signal, becomes L by the set signal, and is input to the shift register 19. The carry signal is inhibited by the 1H correction signal G and the one word delay signal, and the display content is 11 o'clock. Furthermore, in the state shown in Fig. 6g, when ten key U is set twice, F-F3O and 3l both detect O and send a set signal to AND gate 27, so that The digit is set to the content of l and the display content becomes 01 o'clock.

As described above, in the conventional correction method in which the correction is made by adding l at a time, the AND gate 21 judges the contents of 6, the AND gate 22 judges the contents of 2, and the AND gate 23 judges the contents of 13. I should have configured it.

However, when making corrections using a numeric keypad, if a conventional correction circuit is configured, the time may be corrected to a time that is not displayed as a clock, such as 93 minutes. The present invention
The AND gate 21 is configured to judge 6 or more, the AND gate 22 judges 2 or more, and the AND gate 23 judges 13 or more, so that when the time is adjusted to a time that is not displayed as a clock, it is displayed as a previously set clock. It is automatically adjusted to the displayed time.

In addition, if ANDGATE 20 makes a judgment of 10 or more, there will be no problem when carrying or editing, but when the power is turned on, the content may be 10 or more, so it was configured to make a judgment of 10 or more. . FIG. 7 is an embodiment of the present invention, and shows a clock circuit of a computer watch that has a function of prohibiting time adjustment when a time that is not displayed on a clock is entered on the numeric keypad. FIG. 8 shows the modified control circuit of FIG.

FIG. 9 shows the display contents of the display section in the embodiment shown in FIGS. 7 and 8. Under normal conditions, time information is
Information is stored in a circular loop consisting of a shift register 51, AND gates 54, 55, an OR gate 56, and a shift register 57, and the other configurations are the same as the conventional correction method by adding 1 at a time. Explanation will be omitted.

However, in order to make the clock display easier to understand by separating the minute and second digits and the hour and minute digits, the configurations of the corresponding registers and carry signals are different. When a time that is not displayed as a clock is set on the numeric keypad according to Figures 7, 8, and 9,
Explain the function that prohibits time adjustment.

Figure 9a shows the clock display (7:56:43) and the calculation display (
12345678), and either display is selected and displayed.

The process of adjusting the time from 7:56:43 to 12:34:00 will be explained.

When the control switch of the keyboard is set to the unlocked state, all the digits start blinking as shown in Fig. 9b.

This is because the OR gate 61 in FIG. 8 works and sends a blinking signal for all digits to the OR gate JMoV. In this state, is the digit specified key date? Press the button to set seconds F-F58,
A second digit flashing signal is sent to the or gate JMoV. The display section in this state is shown in FIG. 9c. In this state, 00
When it reaches the second, if you enter the numeral number n, then the AND gate 6
2, a 00 second regulation signal L is generated, and in the same manner as in FIG. 4, it is determined whether the time is 30 seconds or more, and a reset signal and a carry signal are sent. The reset signal inhibits the second alarm from AND gate 54 by AND gate 55 in FIG. Also, the AND gate 75 is activated by the signal from the AND gate 63 in FIG. 8, and sends a shift control signal K to the AND gate 54 in FIG.
Second information sent from the shift register 51 is prohibited. When numeric keys 1 to (5) are entered, the second information sent from the shift register 51 is similarly prohibited, and the contents of the entered keys are changed to OR gate 68 and AND gate 7.
4 and is sent to the shift register 57 from the OR gate 56 in FIG. 7 as the input number H. In this way, corrections can be made in 10 second increments. When ten key is placed once, F-F
64 is set and sends a signal to F-F67
Transmit the beam set signal to F-F58, 59, 6O, 64, 65
, 66. As a result, the OR gate 61 is activated and sends a blinking signal for all digits to the OR gate JMOV, so that the display section becomes as shown in FIG. 9d. In this state, when the digit designation key E is pressed, the minute FF59 is set and a minute digit blinking signal is sent to the OR gate JMOV, and the minute digit starts blinking as shown in Figure 9e.

In this state, when the numeral numeral (3) is entered, information on the minute digit is prohibited by the AND gate 54 in FIG. It is sent to register 57. 8F-F65 is set, so the display section becomes as shown in FIG. 9f. In this state, in the same way as if you set the number one (4),
FIG. 7 AND gate 54 inhibits information on the minute digit, and OR gate 56 sends the contents of 4 to the one minute digit to shift register 57. At this time, the 4-bit shift register 52 contains the contents of 3 previously input, and the AND gate 76 in FIG.
Send it to the figure AND gate 53. As a result, the contents of 3 are sent to the shift register 57 through the AND gate 53.
As a result, 34 minutes of information is sent to the shift register 57. When a group of ten keys is set, F-F66 is set and sends a signal to F-F67, and F-F67 sends a reset signal in the same way as for seconds, so OR gate 61 works and sends a flashing signal for all digits to OR gate J. The display section will appear as shown in Figure 9g. In this state, when the counter designation key [=] field is pressed, the hour F-F6O is set and the hour digit starts blinking as shown in FIG. 9h. In this state, if the numeral 1 (1) is placed, the display will appear as shown in Figure 9 (1) in the same way as the minutes, and if the 1 (2) is placed, the display will appear as shown in Figure 9 (j). become. Now that the time adjustment is complete, return the control switch to the normal state and the result will be as shown in Figure 9k. In the state shown in FIG. 9c, when numerals 6 to (9) are entered, the AND gate 70 operates and prohibits the one-word signal for correction (generated by the AND gate 80), so that the time is corrected. is prohibited.

Since F-F64 is set, the display section looks like d'0 in FIG. 9. In the state shown in Figure 9e, ten keys 6 to (9)
When is entered, the contents of the entered key are input, and the display section becomes as shown in FIG.
F73 is set.

In this state, if numeric key is entered once to n, F-F
73, the l word signal for correction is prohibited, and therefore time correction is prohibited. Since F-F66 is set, the display becomes as shown in Fig. 9 f''. In the state shown in Fig. 9 h, when numeric keys 1 (2) to 9 are entered, the AND gate 7
1 works and sets F-F73, so the contents of the display section become as shown in Figure 9 I. Next, when numeric keys 6 to (9) are set, the l word signal for correction is inhibited. Therefore, time adjustment is prohibited and the display section becomes as shown in FIG. 91''.

In the state shown in FIG.
Since the word signal is prohibited, time adjustment is prohibited and all digits start flashing as shown in Figure 9j. In the state shown in Figure 9h,
When numeral → 6 is entered, AND gate 78 works,
Since the 1-word signal for correction is prohibited, 0 time correction is prohibited.

As mentioned above, we judge whether the time entered by the numeric keypad is displayed as a clock and input it to the shift register.
When a time that is not displayed as a clock is entered, input to the shift register is prohibited.

Also, when a time that is not displayed as a clock is entered,
Using the signal of F-F73 and the signal of OR gate 79,
It is desirable to provide a means for notifying the user that a time that is not displayed on the clock has been set.

For example, in a watch with a calculator, an (error) display of calculation display E is displayed. Alternatively, a dedicated display may be provided.
Furthermore, a warning means such as a buzzer may be used.

In the example, only hours, minutes, and seconds were explained, but
The same applies to the day of the week, date, month, year, etc. In addition, when a time that is not displayed as a clock is set using the numeric keypad, in the method of correcting the set time, in the embodiment, the set time is set as seconds, minutes as 0, and hours as 1. However, it is not limited to this. Further, the correction method is not limited to the order of seconds, minutes, hours, and so on, and since there are digit designation keys corresponding to the correction digits, the correction order can be changed freely. Further, the present invention is not limited to a computer watch, but can also be used for an alarm watch, a stopwatch, etc. that have a keyboard. As described above, the present invention is capable of correct time adjustment by detecting when a time that is not displayed as a clock is set on the numeric keypad and correcting it to the set time, or prohibiting the correction. To provide a clock with a keyboard that can be easily and clearly corrected.
