Next, the operation of the electronic timepiece having the above configuration will be explained. First, in the time display mode in which the function selection circuit 44 specifies the time terminals T and K, the display switching circuit 40 selects the signals from the information generation circuit 22 and the numeric signal generation circuit 36, as shown in FIG. A time counter 2 is provided on the first display section 3 of the electro-optical display device 2 shown in FIG.

Figure 3 shows this time display state.
12:35:20, October 21, 1982 MO (Monday), illuminance 500 LUX is displayed.

Next, the operation of correcting the above-mentioned time and calendar information by the correction signal generating circuit 35 will be explained. By operating the function selection switch 10' three times, the function selection circuit 44 generates a designation signal to the time correction terminal TC, and puts the information creation circuit 22, information digit designation circuit 45, and display switching circuit 40 into the correction operation state. At the same time, the sensitivity adjustment function provided in the numerical signal generating circuit 36 is controlled via the OR gate 52 to switch to increase the detection sensitivity, and at the same time, the signal output from the numerical signal generating circuit 36 is changed from the illuminance display signal. Switch to numerical display signal for correction.

The state of the illuminance display section 5 at this time is shown in FIG.
That is, by switching to the correction mode and increasing the detection sensitivity, the numerical signal generation circuit 36
At a light intensity of 500LUX, a signal is generated at the maximum output terminal _T9 , and only the number 9 is displayed as shown in Figure 4A.

In this state, by partially covering the solar cell 7 with your hand, the numerical signal generating circuit 36 generates numerical signals at each terminal T _N to _{T 9} according to the amount of light.
Only the number on the illuminance display section 5 corresponding to that number is displayed.

Figure 4 (b) shows the state in which the number 6 is displayed, and Figure 4 (c) shows the T _N
This shows the state in which the terminal is selected.

Next, the actual correction operation will be explained. First, when the switch 9' is operated once to set the information digit selection circuit 45 to the specified state of the seconds designation terminal S, the seconds digit on the first display section 3 starts flashing.

In this state, when the switch 8' is operated in accordance with the time signal, the write pulse P _r generated thereby is supplied to the information generating circuit 22, and the second digit is reset to zero.

Next, when the information digit designation circuit 45 is set to the designation state of the minute designation terminal M, the one-minute digit number in the minute information on the first display section 3 starts flashing.

In this state, by partially covering the solar cell 7 with the hand, a desired number is called up on the illuminance display section 5, and the switch 8' is operated.

The write pulse P _r generated by this operation writes the number displayed on the illuminance display section 5, that is, the correction number signal supplied from the number generation circuit 36, into the 1 minute digit of the time counter 23. Stop the flashing with , and at the same time start the 10-minute flashing.

Even in this state, the desired number can be written in the 10-minute digit using the same operation as for the 1-minute digit described above. The writing pulse P _r written to the 10-minute digit causes the flashing to move to the 1-minute digit, and thereafter, the flashing moves alternately between the 1-minute digit and the 10-minute digit with every write pulse.

Further, when this movement operation is performed in the N selection state shown in FIG. 4C, the number of the flushing digit is not changed and only the movement is performed.

Once the minute information has been corrected through the above operations, the information digit designation circuit 45 is shifted to the hour designation terminal selection state by operating the switch 9' again.
Correct the 1 o'clock digit and then the 10 o'clock digit in the same way as the minute information correction operation described above.

Below, the day information, month information, and year information can be corrected in the same manner.

Next, a description will be given of an operation for correcting day of the week information in which information is displayed in alphabetical characters. When the information digit designation circuit 45 designates the day-of-day designation terminal W, the two-digit day-of-day information on the second display section 4 starts flashing.

In this state, when the solar cell 7 is briefly covered with a hand, the change in the amount of light caused by the movement of the hand causes the correction pulse generation circuit 3 that constitutes the correction signal generation circuit 35 to change.
7 becomes the corrected pulse P _c , and the information creation circuit 2
2.

As a result, the day of the week information display section displays seven types of English letters: SA, MO, TU, WE, TH, FR,
SA is sequentially selected and displayed each time the correction pulse P _c is supplied.

When the desired day character is selected, the switch 8' is operated to supply a write pulse _Pr to write the day information.

The above is the correction operation of the information creation circuit 22 using the correction signal generation circuit 35, but the time setting for the alarm memory 26 in the alarm mode can also be performed in a similar manner.

Next, the memo mode will be explained. When the function selection circuit 44 is set to the memo mode by operating the function selection switch 10', a designation signal is generated at the memo terminal ME, the memo device 31 and the memo designation circuit 46 are put into operation, and the display switching circuit 40 is set to the memo mode. The display mode is switched to 31, and further switched to increase the detection sensitivity of the numeric signal generation circuit 36 via the OR gate 52.

FIG. 5 shows the display state in the memo mode. That is, the hour and minute display section of the first display section 3 shows the hour,
The minutes are displayed as they are, but the second display section of the first display section 3 displays the memo number designated by the memo designation terminals M _a to M _o , and the second display section 4 displays the memo number that was displayed. The contents of the memo counter 31a read into the rewriting circuit 32 of the memo device 31 in response to
It is displayed as a 10-digit number and 2-digit alphanumeric characters.
Furthermore, a memo mark ME is displayed on the function display section 6.

In other words, the above display content means that the phone number 0425.26.6152 of the person whose initial is TK is memorized in the memo counter 31a with memo number 1.

When the switch 9' is operated from this state, the designated terminal of the memo designating circuit 46 is switched from _M1 to _M2 , and the _M2 terminal of the display switching circuit 40 is designated, so that the seconds display part of the first display part 3 is changed. The memo number 2 is displayed, and by specifying the _M2 terminal of the memo device 31, the memo counter 31 is displayed in the rewriting circuit 32.
Since the contents of ``b'' are read, the initials and telephone number memorized in the memo counter 31b corresponding to memo number 2 are displayed on the second display section 4.

Thereafter, in the same manner, the contents of the memo counter corresponding to the memo number can be called up on the second display section and the second display section 4 in accordance with the operation of the switch 9'. That is, the telephone directory stored in the memo device 31 can be turned over by operating the switch 9'.

Next, the operation of writing information to each memo counter 31a to 31n constituting the memo device 31 will be explained.

First, a memo counter for writing is called up to the rewriting circuit 32 by operating the switch 9', thereby bringing it into a display state.

In this state, when switch 8' is operated once, the first write pulse P _r generated causes the second
The display digit at the left end of the display section 4 starts flashing.

The first digit of the phone number is written into this flashing display digit, but this writing method is
This is exactly the same as the writing method in the time adjustment mode, and by partially covering the solar cell 7, the specified number on the illuminance display section 5 is displayed on the switch 8'.
By operating , it is possible to write to the display digits on the right in sequence.

And the write pulse that wrote the 10th digit of the phone number
When the first digit of the initial starts flashing due to P _r , the correction pulse P generated by the method of correcting the day information in the time correction mode, that is, by simply covering the solar cell 7. By supplying _c to the writing circuit 32 of the memo device 31, alphabetic characters are called up cyclically to the flashing display digits, and a two-digit initial is written by operating the switch 8' to write the desired alphabetic character. Can be written.

Thereafter, in the same manner, the switch 9' is used to write to the write circuit 32.
You can correct or rewrite the phone number on the memo counter called up.

As mentioned above, in the present invention, by using the solar cells installed in small electronic devices such as electronic wristwatches for multiple purposes, it is possible to significantly improve the marketability and functionality. By applying the changes in numerals to the selection of numbers, it is possible to solve the troublesome operation associated with changing numeric information, which has traditionally been considered a weak point in small electronic devices.
