When the mode is specified so that the device operates as an arithmetic circuit, the function keys 2mB to 2q operate with the functions of ÷, ×, 1, 10, and =, which are provided in a normal electronic desk calculator; On the other hand, when the device displays the time, it operates with the function of specifying the time elements of hour, minute, day, A/P, and week. That is, the function keys 2m to 2q are provided for both a clock circuit and an arithmetic circuit. Incidentally, which function the function keys 2m to 2q are operated with is determined by switching a first switch S, which will be described later. The remaining touch electrodes 2r are electrodes that work effectively only in the watch mode, and their operation will be described later. In addition to the 18 touch electrodes mentioned above, case la has
A first mechanical switch S for switching between a computer and a clock function, and a second mechanical switch S2 for switching between a correction mode and a non-correction mode of the clock are provided to constitute the switch group of this device. The central part of the device 1 has 6 lights such as LCD, LED or electrochromic.
A display 3 consisting of digits displays the time or a calculated value based on the designation of the switch group.

Days of the week are displayed as dots. FIG. 3 shows a block diagram of an electronic wristwatch with a watch strap according to the present invention.

In FIG. 3, 5 is CMOS 1, which has the clock and computer functions built into one semiconductor chip as an LSI. 2 is the touch switch group mentioned above, which is the input key of the calculator,

The above oscillation circuit is used both for the source oscillation of the clock (oscillation frequency 32768 Hz) and for the control clock of the computer. Next, the above I circuit 5 will be explained using the block of FIG. 4.

The GI circuit 5 is provided with a control clock generator 51 that generates the clock's original oscillation and all the control clock signals of the computer based on the vibration output of the crystal oscillator 6, and also corresponds to the operation of the key electrode group. an input section 52 for forming an input signal;
A control section 53 that inputs key signals of the input section 52 and signals from the control clock generation section 51, a calculation section 54, a clock register 55 that counts and stores time signals, and a time signal or calculation signal that is sent to the display 3. It is composed of an output section 56 and the like that converts the signal into a signal suitable for transfer.

An overview of the operation will be explained using the above block diagram. usually,
When operating as a clock, the control clock generator 51 adds 1 to the contents of the second register every second via the control section 53 and the calculation section 54, and the clock register 55 adds 1 to the contents of the seconds register. The register 55 displays the time measurement contents on the display section 3 via the output section 56 while storing it. When setting the time on the clock, set the time signal mode using the first and second switches S and S2, and then input the contents to be set using the function keys and numeric keys on the control unit 5.
An input signal is sent to the controller 53, and this input signal causes the controller 53 to
The calculation unit 64 transfers the numerical value to be set to a predetermined digit of the clock register 55. The contents set in the clock register are displayed on the display section via the output section, as in the case of normal clock operation. When operating as a calculator, input signals are sent from the function keys and numerical keys to the control section 53, the arithmetic section executes a predetermined operation in response to a control command, and the content of the operation is displayed on the display section 3 via the output section.

FIG. 5 shows the input section 52 and control section 53 of the above-mentioned I circuit together with the types of input/output signals.

Among the signals given from the input section 52, the first switch S,
The signals from the second switch S2 and the second switch S2 are input to the mode setting circuit 531, and the clock mode signal T, computer mode signal T, and time correction mode signal T2 are generated in response to the operation of each switch.
and outputs the unmodified mode signal L to the display control circuit 532 and the function selection circuit 533. The display control circuit 532 further receives a signal from the touch electrode 2r that is effective only in the clock mode, and generates a first display signal t that displays six digits of hours, minutes, and seconds, or a second display that displays days and weeks. The signal t is output to the function selection circuit 532. The function selection circuit 533 receives signals from the touch electrodes 2a to 2q as well as output signals from the mode setting circuit 531 and display control circuit 532, and outputs numerical signals and various function signals. Here, TW is the week adjustment signal that can also be used in time adjustment mode, TD is the day adjustment signal, and T
H is an hour correction signal and TM is a minute correction signal. FIG. 6 is a detailed circuit diagram of the mode setting circuit of FIG. 5.

In the figure, a first switch S is a switch for switching between a clock mode and a computer mode, and a second switch S2 is a switch for switching between a clock correction mode and a non-correction mode. A circuit consisting of flip-flops F, , F2 and an AND gate Q constitutes a single pulse generating circuit, and the first switch S. Generates one pulse each time you press .

When S is pressed once when the device is in the clock non-correction mode T,,T2, one pulse is inputted to the input of flip-flop F5 through AND gate G4, the state of F5 is reversed, and the computer mode signal T, Output.

When the clock is in the correction mode T,,T2, even if S is pressed, the gate of G4 is closed, so F5 cannot be inverted. Conversely, when in the computer mode, G4 is always in the open state, so when S is pressed once, F5 is inverted and outputs the clock mode signal T. Similarly, flip-flops F3 and F4 and AND gate ○5 constitute a single pulse generation circuit, and each time S2 is pressed, one pulse is output from the G5 output.

AND gate G6 is open only in clock mode T, and if you press S2 in this state, F6 will open every time you press S2.
is inverted and outputs a modified mode signal T2 or a non-modified mode signal T2. AND gates G7 and ○8 output clock correction mode signals T,
, T2, and generate clock non-correction mode signals T,, T2. FIG. 7 is a detailed diagram of the display control circuit 532 of FIG.

When the watch is in the non-correction mode, the signals T, , T2 are in the "1" state. If there is no input from the touch electrode 2r in this state, the AND gate G9 output is ``0'', and the inverter G
,. The output becomes "1", the outputs of the AND gates ○, 2 and the AD gates G, 3 also become "1", and the hour, minute, second first display signal t becomes "1". Next, when the touch electrode 2r is input, the G9 output becomes ``1'', G,.The output becomes ``0'',
G,2, G,3 output becomes "0", and inverter G,4
The output becomes "1". Therefore, while input is being made to the touch electrode 2r, the day/week second display signal t becomes "1". That is, when the watch is in the non-correction mode, the touch electrode 2
If the r input is not input, the display unit 3 will display (hours, minutes, seconds), and if the touch electrode 2r is input, the display unit 3 will display (hour, minute, second) while the input is being made.
day, week). Next, when the clock is in the correction mode, the signals T, , T2 become "1", and the AND gates G, . is open. When the touch electrode 2r is input in this state,
Since the state of flip-flop F7 is inverted every time G, . The output inverts from "1" to "0" or from "0" to "1" every time one input is made to the touch electrode 2r, and the G and 3 outputs similarly change from "1" to "0" or " Change the state from "0" to "1". In other words, when the clock is in correction mode, when 2r is input, the display changes from (hours, minutes, seconds) to (days, weeks) every time 2r is input.
Yes, or vice versa, switching the display from (day, week) display to (hour, minute, second) display. Moreover, due to G9, public input is only possible when the clock mode signal T is "1" (hours, minutes, seconds), (day,
week) display control is possible. Further, the A and P displays indicating AM and PM are displayed only when the clock is in the correction mode, that is, when the G7 output in FIG. 6 is "1", and are not displayed in the non-correction mode of the clock.

A circuit block 533 in FIG. 5 is a function selection circuit, and is composed of a group of selection gates.

Among the function inputs of the touch electrode group, ten (A/P), one (day), and
× (minutes), ÷ (hours) and = (weeks) are in calculator mode (T,
When is 1), the functions 10, 1×, ÷, and = are selected and the commands necessary for calculation are sent. Next, when the clock is in correction mode (T,, T2 is 1), (A/P), (day), (
The following functions are selected: (minutes), (hours), and (weeks).

Moreover, when (hours, minutes, seconds) is displayed (t is 1), (
Only hours), (minutes), and (A/P) are selected, and TH, TM, and A/P signals are output to the selection gate outputs, respectively. Similarly, when the (day, week) display state (t is 1),
Only (day) and (week) are selected and TD and TW signals are output to the selection gate outputs, respectively. Next, calendar number key 2
When inputting c (L), lamp lighting signal L is selected only when the clock is in non-correction mode (T,, T2 is 1), and when the clock is in correction mode (T,, T2 is 1), it is a numerical value. Signal 2 is output from the selection gate.

C/CE and dot (・) are computer mode (T2 is 1)
C/C is selected only when the selected gate output is selected.
E, - A signal is output. 0, 1, 3, ..., 8, 9 are in computer mode (L is 1) or clock correction mode (T
,, is selected only when T2 is 1), and outputs a numerical input signal from the selection gate output.

Therefore, when setting the time of the clock by operating the switch S and the switch S2, first input the function to be set, and then the signal TD,
TH or TM is sent to the control unit 53 shown in FIG. 4, and thereby the contents of the "day" register, "hour" register, "minute" register, etc. provided in the clock register 55 are cleared and output. The cleared content "00" is displayed on the display section 3 via the section 56 in the corresponding display digit.

Next, when a numerical value to be set is input, the numerical value is entered into the register of the calculation unit 54 and then transferred to the corresponding digit of the clock register 55 to set the time. Regarding week setting, each time a TW signal is sent in pulse form, the contents of the week register in the clock register are counted up by one. The contents of the week register are displayed on the display section via the output section 56 at the 4.several point positions. The display section 3 is provided with seven dot positions corresponding to six digits, and each dot position serves as a decimal point in the case of a calculator, and displays the day of the week in the case of a clock. The mode switching operation of the electronic wristwatch with calculator constructed from the above circuit will be explained. First, to switch between watch mode and computer mode, use the first switch S.
As is clear from FIG. 6 in the clock non-correction mode, the first switch S is switched alternately each time the first switch S is operated.

At the same time, the display switches alternately between a clock display (hours, minutes, and seconds) and a calculator display, but in the case of the calculator display, it is automatically cleared and the first digit is clearly different from the time display, with a zero and a dot (0 .) is displayed to indicate that the switching operation has been performed. It goes without saying that even if the above switching is performed by the switch S, the clock circuit section continues to perform normal clock operation. Note that the gate G4 causes the switch SS. Even if you operate , switching to computer mode will not occur.

Switching between the non-correction mode and the correction mode in the clock mode is performed by the second switch S2, and when the second switch S2 is operated once from the non-correction state, the correction mode is switched.
A or P will be displayed on the right shoulder of the display to indicate that the correction mode has failed.

This display of A or P is also performed when the display is in the day or week display state. In either case, A and P light up when in the correction mode state. When A or P is displayed, time can be set using the touch electrode. Even in the correction mode, the normal clock operation continues unless the time is set. When the second switch S2 is operated once in the correction mode, hours, minutes, and seconds are displayed in the non-correction mode.

When setting the time in the above correction mode, when the touch electrode 2n ("hour" key) is touched when the hours, minutes, and seconds are displayed, the time display digits are cleared to "00" at the same time.

Next, the numerical value of the time to be set is transmitted to the calendar number touch electrodes 2a to 2.
If you select from j and touch it, the value set in the time digit will be displayed. A and P are alternately switched each time the touch electrode 2P is touched once. The counterfeit touch electrode and the touch electrode 2P can be operated in any order.
When the second switch S2 is operated again after setting the "hour", the mode returns from the correction mode to the non-correction mode, the A and P displays disappear and the hours, minutes and seconds are displayed. Next, when setting the "minute" digit in the correction mode, if you touch the touch electrode 2n, the "minute" digit and "second" digit of the clock register will be reset at the same time as this contact, and will become "00" minutes, "00" seconds, and " Counting operation will stop until the count exceeds the number of seconds. Next, when you touch the numerical electrode to be set, the set value will be displayed in the "minute" digit. This operation completes the "minute" setting, but the second count remains reset while in the correction mode after correcting the "minute", and the reset state is canceled at the same time as operating the second switch S2 in time with the time signal. It returns to non-correction mode and starts normal clocking operation. Function keys 20 and 2q do not work when hours, minutes, and seconds are set. "Day"
When making settings, the touch electrode 2r is connected to display the hours, minutes, and seconds in the correction mode, and the display is first switched to the day and week display.

In this state, when the touch electrode 20 is touched, the "day" digit is reset and "00" is displayed. Next, operate the touch electrodes for the desired number of layers to set and display a numerical value in the "day" digit. After setting, when the second switch S2 is operated, the mode returns to the non-correction mode and hours, minutes, and seconds are displayed. The “Week” setting is “
Same as the "day" setting, when the touch electrode 2q is touched, the week display dot shifts to the right by one each time the touch electrode 2q is touched, and when the dot appears on the day of the week to be set, the setting is completed, and the setting is completed by operating the second switch S2. Return to correction mode. Function keys 2m and 2n do not work in the day/week setting state. In the non-correction mode of the watch, as is clear from Fig. 7, the days and weeks are displayed during the period in which the touch electrode 2r is in contact, and as soon as the touch is released, the hours, minutes, and seconds are automatically displayed. to return to. On the other hand, in the correction mode, touch electrode 2r
Each time you touch the button, the hour, minute, second display and day/week display will alternate, and the display will not change to the other until the next touch. Note that the touch electrode 2r only works in the watch mode, and does not work in the computer mode. As described above, the present invention is an electronic device having a clock function and a computer function, in which the time of the clock function section can be easily adjusted, and a complex electronic device with high practical value can be provided.
