In addition to the calculation control function for executing normal calculations including the four arithmetic operations, the calculation control unit 13 also performs day calculation based on the input date information and day calculation based on the result of the day calculation. The means for calculating the number of days and the day of the week will be explained with reference to the drawings.

First, it is necessary to calculate the number of days by taking into account leap years and the difference in the number of l months, so the following calculation format is calculated.
That is, as the starting date, for example, date data of March 1, 2006 (Monday) is stored in advance in the fixed storage unit of the calculation control unit 13, and this is used as the starting date. Therefore, when calculating the number of days until day b, month c, year a in the Rooster Calendar, if b > 3, if b minus 3, then (however, in formulas 1 and 2, the year term is rounded down to the decimal point, The term is rounded off to the nearest whole number.

Furthermore, by correcting the calculation result value of the above formula 1 or 2 by +1, the number of days information for the set year and month can be obtained. At this time, the date information (year a, month b, day c) can be set by operating the number keys NK provided on the input section 11.
This is done by operating the date key DATE once each time each unit numerical information shown in b) and c) is entered, and the output of the counter 12 indicates that the date key DATE has been operated three times. is sent to the calculation control unit 13, so that the calculation control unit 13 outputs the above formula 1 or 2.
Various control command signals are outputted to execute the calculations of the equations. Furthermore, at this time, the code generator 15 generates the "36
5.25], "30.6", "9", "3", "1", etc. This numerical code and the above date information are used as operand data in formula 1 or 2 above. The expression's operation is performed. FIG. 2 shows the flow of calculating the number of days in this case, and in the figure, AReg is the register 16A. BRe
g indicates register 16B. When the number of days information is determined based on the above calculation flow, the calculation control section 13 then outputs a calculation control command to determine the day of the week corresponding to the set value from the number of days information. This day of the week calculation divides the number of days information obtained by the above days calculation by "7" and uses the remainder as the Yukuta information. The relationship between the remainder number and the day of the week is [remainder 0
→ Sunday", "Remainder 1 → Monday", ... "Remainder 6 → Saturday". Here, set the date to 1976.
FIG. 3 shows an example of the calculation results when January 20th is set. In this case, the day number calculation result value is "722000" after +1 correction, and by dividing this by "7" to obtain a remainder "6", this remainder "6" becomes the day of the day E]-information indicating Saturday. . After this day of the week calculation is automatically executed,
By operating the numeric key NK and time key Hms on the input unit 11, time information (in the embodiment, only "hour" and "minute" information) is set and the knob is turned. It is shown in Figure 4.

In addition, when setting the date mentioned above, enter only the lower two digits of the year using keys, and enter the upper two digits of the year.
The functional configuration is such that the digit year information is automatically added as unchangeable information by a command from the calculation control unit 13 when calculating the number of days.

In addition, the day sign information is recognized and displayed using a decimal point display segment provided for each digit (e.g., 8 digit configuration) of the display section 22, and a panel surface section corresponding to the decimal point display segment of each digit. Add characters to indicate the day of the week information (for example, Sun, Mon...Sat, or SUN, MON...SAT, etc.), and when displaying clock information, set the decimal point display segment to the day of the week information. The day of the week is recognized and displayed by lighting up to the number based on the number. Here, to describe the operation with reference to FIG. 5, when setting clock information, first set the mode setting switch MSW provided in the input section 11 to the clock mode (Time), and then set the mode setting switch MSW provided in the input section 11 to the clock mode (Time). Date (year, month, day) information is set by alternately operating the provided number key NK and date key DATE as described above.

That is, if the setting date is November 20, 1976, first, as shown in Figure 5a, the lower two digits of the year information "
76". As a result, the key common signal of the numeric key NK output from the input unit 11 is sent to the arithmetic control unit 13. Based on this, a command from the arithmetic control unit 13 causes the numeric code “76” to be sent to the input control gate circuit 21. are stored in the first digit (LSD) and second digit of register 16X. Further, the code data "76" stored in the register 16X is sent to the display section 22, decoded and displayed as the fifth
It is recognized and displayed as shown in Figure a. Next, by operating the date key DATE once as shown in FIG. In response to a command from the calculation control unit 13, the code data "76" stored in the register 16X is transferred to the first and second digits of the register 16A, and the contents of the register 16X are carried up by three digits. Therefore, the display state of the display section 22 becomes as shown in FIG. 5b.Next, when month information "11" is entered as shown in FIG. It is stored in the first and second digits and is recognized and displayed as shown in FIG. 5c.

Next, as shown in Figure 5d, the date key DATE is set to 1 again.
By operating the counter 12 times, the contents of the counter 12 are incremented by +1 and become [2], and the code data "11" stored in the lower two digits (first and second digits) of the register 16X is added.
'' is transferred to the first and second digits of register 16B, and the contents of register 16X are further carried up by three digits. Therefore, the display state of the display section 22 is as shown in FIG. 5d. Next, as shown in FIG. 5e, when mark information "20" is entered, this number code "20" becomes
It is stored in the second digit, and the display state of the display section 22 is as shown in Fig. 5e.
It will be as follows. Next, as shown in FIG. 5f, when the date key DATE is operated for the third time, the counter 12
The content of ``3'' is sent to the calculation control unit 13, and the calculation control unit 13 outputs this count as ``3''.
When it is determined that the number of date information has been set, various control commands are outputted to execute the number of days calculation and the day of the week calculation as described above. Based on this control command, the code generator 15 obtains "365.25", "
The selector gate circuit 1 uses various unique numerical codes such as ``30.6'', ``9'', ``3'', and ``1'' and the year, month, and day numerical codes stored in registers 16A, 16B, and 16C.
7 and are sequentially supplied to the calculation section 18, where the number of days calculation is executed according to the calculation mode shown in FIG. 2 above. When the number of days calculation result is further determined, the number of days calculation result and the unique numerical code "7" newly output from the code generator 15 are sent via the selector gate circuit 17 according to a command from the calculation control unit 13 again. The data is sent to the calculation unit 18, and a day of the week calculation is performed using the day number calculation result value as the dividend and the numerical code [7] as the divisor to find the remainder. Then, when the Yoda information, that is, the remainder number (see Fig. 3) is obtained by this day-of-the-week calculation, once the contents of the registers 16A, 16B, and 16C are cleared, the calculation unit 18 can obtain the Yoda information. Day of the week information, ie, the remainder number, is stored in a predetermined digit (for example, the 10th digit) of the registers 16B and 16C via the input control gate circuit 21. Furthermore, the arithmetic control unit 13 refers to the remainder stored in the register 16 and sets the value in the register 16.
From the 8th digit of A to the lower digits") number code "14"
'' is issued, and a predetermined number of decimal point codes ``14'' are stored sequentially from the 8th digit to the lower digits of the register 16A by arithmetic control operations based on this instruction. That is, every time the decimal point code "14" is stored in the register 16A from the 8th digit, the register 16A
The remainder number stored in register 16C is subtracted by -1 by the calculation unit 18, and until the calculation unit 18 outputs the BORO-1 signal, that is, the remainder number stored in register 16C becomes [-0].
Decimal point code [14'' to register 16A until
. . . writing is executed. Therefore, if the remainder number calculated by the day of the week calculation is "6" (Saturday),
The decimal point code is written in the second to eighth digits of register 16A.
14]... is written. Therefore, register 16
The decimal point code "14" stored in A is sent to the display unit 22 along with the setting year, month and ten information stored in the register 16X, and therefore the display unit 22 shows the information shown in FIG. 5f. Thus, the set date information and the day of the week information corresponding to the set date are recognized and displayed using decimal points. In this way, the day of the week information is automatically set based on the date setting information and is recognized and displayed. After the day of the week information is automatically set, time (hours, minutes) information is set by operating the numeric keys NK and time keys 11IT]S. That is, when the set time is 8:30 (am), the hour information "8" is first set as shown in FIG. 5g. As a result, the key common signal of the numeric key NK is sent to the calculation control unit 13, and according to the control command at this time, the date information stored in the register 16X is transferred to the register 16B, and
Time information "8" is stored in the first digit of the register 16X which is in the clear state. The numeric code "8" stored in this register 16X is sent to the display section 22, and the time information "8" to be set is recognized and displayed as shown in FIG. 5g. Next, by operating the time key Hms once as shown in FIG. The contents of register 16X are carried up by three digits, and the date information "20" stored in the first and second digits of register 16B is transferred to the seventh and eighth digits of register 16X. The contents of this register 16X and the day of the week display information stored in register 16A,
