As described above, the first method is the down key
The month information is updated when the 13b and the up key 13c are operated independently, and the year information is updated when operated in combination with the function shift key 13e.

Therefore, not only when the calendar after several years or before is displayed but also when the calendar after 11 months is desired to be displayed, the down key 13b is not operated 11 times in succession, but the function shift key is used. By operating the 13e and the down key 13b to display the calendar one year later, and then operating the up key 13c to display the calendar one month ago, a desired calendar can be displayed. The operation can be greatly simplified.

Next, the second method will be described with reference to FIGS. FIG. 4 shows the contents of processing by the CPU 11 after operating the “calendar” key 13a which partially overlaps with FIG. 2, and as shown in FIG. 7A, the “calendar” key

The calendar of will be displayed.

Further, as shown in FIG. 7 (4), the function shift key 13e, the numeric keypad 13d "6" and the down key 13b.
When is operated, the first operation of the function shift key 13e is judged in the step B3, and then the numerical value "6" inputted by the ten key 13d is held in the Z register 14a of the RAM 14 (step B4).

Thereafter, it is judged whether or not the numerical value held in the Z register 14a is less than or equal to a preset value "5" (step B5). Here, it is judged that the numerical value is larger than "5", and then the numerical value is exceeded. It is determined whether the down key 13b or the up key 13c is operated subsequent to (step B
Ten).

Since the down key 13b is operated here, the input numerical value "6" held in the Z register 14a is used to calculate X year Y month after "6" months (step B11). ).

FIG. 5 is a subroutine showing the detailed processing contents of this step B11.
The month information "4" held in 14c is added to the input numerical value "6" held in the Z register 14a, and the obtained addition value "10" is RA.
It is held in the B register 14e of M14 (step C1).

Next, the value "9" obtained by adding "-1" to the value "10" held in the B register 14e is held in the C register 14f (step C2), and the value "9" held in the C register 14f is set. The division is performed by the constant "12", and the quotient "0" is held in the D register 14g and the remainder "9" is held in the E register 14h (step C3).

Then, the year information "1995" held in the X register 14b is incremented by the numerical value "0" held in the D register 14g, while the numerical value "9" held in the E register 14h is incremented by "+1". "10" is set in the Y register 14c (step C4), and this subroutine is completed and the process returns to the process shown in FIG.

In FIG. 4, the X register 14b, Y
Calendar RO using the year and month information in register 14c
M12 is accessed, the calendar information is calculated and read out and displayed on the display unit 16 (step B8), and the process is once ended. Here, as shown in FIG. 7 (4), the calendar of "October 1995" six months after the state of "April 1995" shown in FIG. 7 (3) is displayed. .

If it is determined in step B6 that the up key 13c is operated, the year information stored in the X register 14b of the RAM 14 is subtracted from the input numerical value stored in the Z register 14a and set ( In step B9), next, in step B8, a calendar display is performed based on the date information held in the X register 14b and the Y register 14c.

In step B10, the function shift key is pressed.
When it is determined that the up key 13c has been operated following the numerical input by the 13e and the numeric keypad 13d, the input numerical value Z held in the Z register 14a is used next and the X number of Z months before is input.
The year Y month is calculated (step B12).

FIG. 6 is a subroutine showing the detailed processing contents of step B12. First, the Y register of the RAM 14 will be described.
The input numerical value stored in the Z register 14a is subtracted from the month information stored in 14c, and the obtained subtracted value is stored in the B register 14 of the RAM 14.
It is held in e (step D1).

Then, it is judged whether or not the value held in the B register 14e is negative (step D2). If negative, the absolute value of the negative value held in the B register 14e is set to a constant "12". Divide by and divide the quotient value (integer) into D register 14
g is made to hold the remainder value in the E register 14h (step D3).

Then, the numerical value held in the D register 14g is subtracted from the year information held in the X register 14b, and the value "-1" is held and set in the X register 14b.
The subtraction value obtained by subtracting the numerical value held in the E register 14h from the constant "12" is set in the Y register 14c (step D4
), The subroutine is finished as described above, and the process returns to the process shown in FIG.

In step D2, the B register 14e
If it is determined that the value stored in the register is not negative, it is then determined whether the value stored in the B register 14e is "0" (step D5). To the processing of. Furthermore, if it is determined that the value held in the B register 14e in step D5 is not "0", that is, it is a positive value, the B register
The value held in 14e is transferred and set to the Y register 14c as it is (step D6), and the above subroutine is finished to return to the processing of FIG.

In FIG. 4, the X register 14b, Y
Calendar RO using the year and month information in register 14c
M12 is accessed, the calendar information is calculated and read out and displayed on the display unit 16 (step B8), and the process is once ended.

In FIG. 4, it is determined whether or not the numerical value input by the ten-key pad 13d is equal to or less than the constant "5", that is, the updated value of the month information which is the updated value of the year information. However, it goes without saying that the numerical value is not limited to "5".

As described above, according to the second method, the updated value of the month information, which is the updated value of the year information, is determined depending on whether the numerical value input by the numeric keypad is larger or smaller than the preset value. It is possible to automatically determine whether or not the update is executed.

Next, the third method will be described with reference to FIGS. FIG. 8 shows the contents of processing by the CPU 11 after operating the "calendar" key 13a which partially overlaps with FIG. 2 and FIG. 4, and as shown in FIG. 8 (1), "calendar".
When the key 13a is operated, the process of FIG. 8 is started, and RA
The year information and month information held in the X register 14b and Y register 14c of M14 are read (step E1).

When the "Calendar" key 13a is operated,
The clock circuit (not shown) in the CPU 11 sets the current year information and month information in the X register 14b and the Y register 14c. For example, if the current time is "May 1993", the X register 14b Is "1993",
Therefore, "5" is held in the Y register 14c. CPU 11 that has read out these year information and month information
Accesses the calendar ROM 12 based on these information, reads the calendar information of "May 1993", and displays it on the display unit 16 as shown in FIG. 9 (1) (step E2).

Then, it is determined whether the function shift lock key 13f is operated (step E3). Here, when the down key 13b is operated as shown in FIG. 9 (2), it is determined that the function shift lock key 13f is not the operation key, and the down key 13b or the up key 13c is operated next. It is judged (step E9).

When it is determined that the down key 13b is pressed, it is determined whether the value held in the F register 14d at that time is "1" (step E10). The F register 14d is set so that the value is inverted between two values "0" and "1" by operating the function shift lock key 13f. At this point, the function shift lock key 13f has not been operated and the initial value is set. Since it is "0", this is judged and the processing from step A9 in FIG. 2 described above, that is, the processing for calendar display one month later is executed. Therefore, here, as shown in FIG. 9 (2), the calendar of "June 1993" is displayed on the display unit 16.

Thereafter, as shown in FIG. 9C, when the function shift lock key 13f, the numeric keypad 13d "3" and the down key 13b are operated, the first function shift lock key is pressed.

It is judged whether or not the value held in the F register 14d is "1" (step E4).

Since it is "0" as described above, "1" is set again in the F register 14d again (step E6), and then the numerical value "3" input by the ten-key 13d.
Is held in the Z register 14a of the RAM 14 (step B
Four ).

At this point, the X register 14b, Y of the RAM 14
Calendar RO using the date information stored in register 14c
Although the calendar information is read from M12 and displayed on the display unit 16 (step E11), the X register 14b and the Y register 14 are used.
Since the content of c has not changed from the state of FIG. 9 (2), the display unit 16 does not change apparently.

Then, when the down key 13b is operated, this is the function shift lock key 13 in step E3.
If it is determined that it is not f and that the down key 13b is operated in step E9, it is determined whether the value held in the F register 14d at that time is "1" (step E10). ). Since the F register 14d is "1" here, the CPU 11 judges this and adds the numerical value by the operation of the ten key 13d held in the Z register 14a to the year information held in the X register 14b. Then, the added value is updated and set in the X register 14b (step E1
1). Here, as shown in FIG.
The calendar of "June 1996" three years after the state of "June 1993" shown in (2) will be displayed.

Thereafter, when the down key 13b is further operated as shown in FIG. 9 (4), the steps E3, E9, E10 are performed in the same manner as the operation of the down key 13b in FIG. 9 (3).
Then, in step E11, the numerical value by the operation of the ten-key 13d held in the Z register 14a again is stored in the X register.
The year information held in 14b is added, and the added value is updated and set in the X register 14b. Here, as shown in FIG. 9 (4), the calendar of "June 1999" three years after the state of "June 1996" shown in FIG. 9 (3) is displayed. .

As described above, by operating the down key 13b or the up key 13c, the year information can be easily updated and set by the value held in the Z register 14a. Then, as shown in FIG. 9 (5), the function shift lock key is pressed again.
When 13f is operated and then the up key 13c is operated, first, when the function shift lock key 13f is operated, this is judged in step E3, and in the next step E4, the value held in the F register 14d is "1". It is determined to be. Therefore, the value held in the F register 14d is inverted to "0" (step E5), and the X register 14b, Y at this time is set.
Calendar RO using the date information stored in register 14c
Although the calendar information is read from M12 and displayed on the display unit 16 (step E11), the X register 14b and the Y register 14 are used.
Since the contents of c have not changed from the state of FIG. 9 (4), the display unit 16 does not change apparently.

Then, when the up key 13c is operated, this is the function shift lock key 13 in step E3.
If it is not f, and it is determined that the up key 13c was operated in step E9, it is then determined whether the value held in the F register 14d at that time is "1" (step E12). ). Since the F register 14d is "0" in this case, the CPU 11 judges this and the above-mentioned FIG.
The process from step A13, that is, the process for displaying the calendar one month before is executed. Therefore, here, as shown in FIG. 9 (5), the calendar of "May 1999" one month before the state of "June 1999" shown in FIG. 9 (4) should be displayed. Becomes

In FIGS. 8 and 9, the year information held in the X register 14b is updated and set by using the numerical value input with the ten key 13d in combination with the function shift lock key 13f. It goes without saying that the month information held in the Y register 14c may be updated. As described above, in the third method, by using the function shift lock key 13f and the ten-key 13d together, it is possible to set an arbitrary update width and execute the update.
