If it is determined that it is not 4n, then step SOG
Then, it is determined whether the contents of the rDTJ register 136 are "3" or not. Here, rDTJ register 136
If it is determined that the content of is not "3", it means that the number of operations of the date key 113 is 2 or 1, and the data of "year", "January", and "mill" are omitted and "hour" is written. ” Only the “minute” data was entered, and in this case it is determined to be an input error.

Further, if it is determined in step 81G that the content of the rDTJ register 136 is °3', the date key 11
3 has been operated three times, so the key human power section 11
Now, the "year" and "month" data have been omitted as the schedule time, and the "day" data has been entered in order, followed by the "hour" and "minute" data, so the process proceeds to step 811.

In step S11, it is determined whether the input "day", "hour", and "minute" data are for this month. That is, the input “day” data of the rDaJ register 133 of the CP tJ 13 and the rXcaJ of the clock circuit 15
This is to compare the current "day" data stored in the register 153. If the "day" data in the rDaJ register 133 is
If the value of the data is greater than or equal to that of the rXcoJ register 153, it is determined that the input "day", "hour", and "minute" data are for this month, so in the following step S12, the clock circuit 15 The current "month" data stored in the rXcxJ register 152 of the rDIJ register 132
After writing the current "year" stored in the "xD" register 151 of the clock circuit 15, the process proceeds to step 808.
Write data to rYJ register 131. Thereafter, data input processing to the time register of the memory 14 in step S05 is performed. In the above step S11, the "day" data of the rDaJ register 133 is changed to the rXcoJ register 1.
If the data is smaller than the "day" data of 53, it is determined that the input "day j""hour""minute" data is for the next month, and the process proceeds to step 813. This step 813
In °, based on the current "month" data stored in the rXcxJ register 152, it is determined whether this month is December. This is because when the next month is the next year, different processing must be performed than for other months.If this month is December, then step 814 is performed. rDt J register 132 as shown in
Enter the data for January in .

Then, in step 309, the current year J data stored in the "XD" register 151 is incremented by "+1" and written to the rYJ register 131, and then in step 805, the data is input to the time register of the memory 14. Process. Also, in step S13 above, rXc

In step 8, the specified address of the CPU 13 to the memory 14 is updated, and this process is ended.

Next, a detailed schedule setting method of the above embodiment will be explained with reference to FIG. The current date in the diagram is 198
This figure shows schedule setting operations for each schedule time on November 15, 2015. First of all, if the schedule time is 9:00 on November 17, 1985, the schedule time and the current time are in the same year and month, so the schedule setting operation is as follows: ``Year J data and ``month'' data are omitted. be able to. Therefore, after inputting "17" using the numeric keys 111 as "day J data" and operating the date key 113, the numeric keys 111 input "hour" and "minute" data as "9 o'clock (00 minutes)".
When the user inputs r9J and operates the date key 113 twice, the schedule setting operation is completed. Then, by operating the schedule key 114, steps S01 to 804 and 806 are executed as shown in FIG. 2 above.
．． 510 to 812.808.805, the data of the schedule time "November 17, 1985 9:00 (00 minutes)" is input and set to the time register of the memory 14.

Next, if the schedule time is 10:00 on December 4, 1985, the "year" data can be omitted in the schedule setting operation because the schedule time and the current time are in the same year. Therefore, "moon""
Date" data is "12" in the numeric key 111, date key 113, "4" in the numeric key 111, date key 11
After operating 3, the "hour" and "minute" data "10 o'clock (
00 minutes)", input "10" using the numeric key 111 and operate the date key 113 twice, the schedule setting operation ends.

Then, by operating the schedule key 114, step 5 (11) is performed as shown in FIG. 2 above.
~304.506~808.305, the data of the schedule time "December 4, 1985, 10:00 (00 minutes)" is input and set in the time register of the memory 14.

If the schedule time is 8:00 on November 9, 1986, the schedule time and the current time are not in the same year, but the "month" and "day" data of the schedule time are earlier than the current time. Therefore, the "year" data can be omitted in the schedule setting operation. Therefore, as "month" and "day" data, the numeric key 111
"11" with the date key 113, "9" with the numeric key 111
”, and the date key 113, enter “8” with the numeric key 111 as the “hour” and “minute” data “8 o’clock (00 minutes) J”, and operate the date key 113 twice.
The schedule setting operation ends. Then, by operating the schedule key 114, the second
As shown in the figure, steps S01 to 804.306, S
via 07.809.805, schedule time r 1
The data of "November 9, 1986 8:00 (00 minutes)" is input and set in the time register of the memory 14.

And finally, the schedule time is November 1, 1986.
If it is 9 o'clock on the 1st, the schedule time and the current time are not in the same year, but the "month" and "day" of the schedule time.
Since this data is later than that of the current time, the schedule setting operation must be input in order starting from the first "year" data. Therefore, "Year""Month"
As the “day” data, use the numeric key 111 to select “1986J”.
, date key 113, numeric key 111 to ``11'', date key 113, numeric key 111 to ``17'', date key 113, then the hour and minute data ``9 o'clock (00 minutes)'' ”, input “9” using the numeric key 111 and operate the date key 113 twice, the schedule setting operation ends. Then, by operating the schedule key 114 after that, the schedule time r is passed through steps 301 to S05 as shown in FIG. 2 above.
The data of "November 17, 1986 9:00 (00 minutes)" is input and set in the time register of the memory 14.

In the above embodiment, by inputting data in units of month, day, and time, or inputting data in units of day and time, data can be input in units of time for the year or in units of time between year and month. Although the present application is not limited to this, for example, by only inputting data in units of time, data in units of time for year, month, and day can also be set. Good too.

[Effects of the Invention] As described above, according to the present invention, when setting the time data to be stored, it is possible to make maximum use of the current date and time data measured by the clock circuit.
It is not necessary to input data in all time units of the time data to be stored, and the time data can be set with a minimum number of data input operations, and the time data setting operation can be extremely simplified.
