DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a structure of a data table on a database in a schedule control device for performing setting for performing schedule control every other week. FIG. 1A shows a format for recording the month to be obtained and the day of the week of the month, and the data of the day of the week is sequentially updated each time after the designated day of the month.

FIG. 1B shows the format of a database for obtaining a date. The difference between the numbers assigned to the first day of the month and the designated day is the first byte data. , In the second to sixth bytes, dates are arranged in week order (first week, second week, ...).

FIG. 1C shows the format of a database for determining the day of the week of the next month. The first byte is the day of the week, and the second to 13th bytes are the day of the week of the next month. Are arranged in the order of months (January, February,...). These FIGS. 1B and 1C are respectively shown in FIGS.
It is configured based on FIG.

[0012] The schedule control device of this embodiment uses a matrix for bi-weekly schedules,
Easy to implement / update. Here, the matrix used has the following as a database. Obtain the difference between the numbers assigned to the day of the day and the specified day of the week. Obtain the day of the month from the difference between the numbers obtained and the specified week. Obtain the day of the week from the day of the day to the day of the next month. Obtain a date from the thing and update it by.

Next, the specific operation of this embodiment will be described with reference to a flowchart shown in FIG. 2 and data lists shown in FIGS.

Now, an example will be described in which the second and fourth Thursdays are set as bi-weekly schedule control setting dates. First, in the format shown in FIG.
The initial setting (for example, if one day is Sunday, the number is 0) based on the day number table shown in FIG.
Is input as the number of the designated day of the week (step S1).

Based on the day of the week (Sunday, the number is 0 because of Sunday) and the designated day of the week (Thursday, the number is 4) inputted in step S1, the difference between these assigned numbers is obtained, and FIG. (Step S2). In this case, according to FIG. 3, since Thursday → 4 and Saturday 1 → 0, the difference between the numbers is 4-0 = 4. When the difference between the numbers is obtained, if the result of the calculation is a negative number or a number of 7 or more, it is replaced as shown in FIG.

When the difference between the numbers is obtained, the date of each week is obtained based on FIG. 5 and stored as the date of each week in FIG. 1B. In this case, since the difference between the numbers is 4, the date of the first to fourth weeks is "5, 12, 1".
9, 26 "is stored (there is no fifth week).

Next, the date of the designated week is obtained by inputting the designated week (steps S3 and S4). That is, since the designated week is the second week, the date of the second Thursday = 12 days is obtained from the format shown in FIG.

If the current date has passed the date obtained in step S4, the fourth Thursday designated next is obtained (steps S5, S8, S2 to S4). On the other hand, if the current date does not exceed the date obtained in step S4, the date designation of the schedule control is rewritten (steps S5 and S6). That is, in the format of the schedule control shown in FIG.
Rewrite the date obtained in step 1.

If the date obtained in step S4 has passed (step S7), it is considered that the schedule control has been executed, and the date of the next designated week (in this case, the fourth Thursday) is set as described above. By performing the schedule control in the same manner as described above, the schedule control is performed every other week (steps S8, S2 to S7).

If there is no next designated week (step S8), the day of the week of the next month (for example, August 1) is obtained by referring to the data shown in FIG. 6 (step S8).
9). Here, FIG. 6 shows data of the shift of the day of the week from January to December from the next month, which is stored in the schedule control device. The shift indicates how much the day of the week of the next month is shifted from that month.

That is, the day of the first day of the following month is the first day of the month.
The number assigned to the day of the first day is determined and updated by adding a predetermined day shift from the next month. Now, assuming that July 1 is Wednesday, as shown in FIG. 7, the number assigned to Wednesday; 3 (FIG. 3) The difference between the days of July 1 and August 1; 3 (FIG. 6) Based on this, 3 + 3 = 6 is updated as the number of the day of the first day of the next month, and it is determined that it is Saturday.

Thereafter, this month is updated to August, Saturday is set as the day of the week (step S10), the contents of FIGS. 1A to 1C are rewritten, and the above steps S1 to S10 are repeatedly executed. Thus, the schedule control based on the designation of every other week is performed.

That is, in the flowchart shown in FIG. 2, steps S1 and S2 constitute a computing means for calculating the difference between the numbers assigned to the day of the first day of the month and the designated day of the week. S8 constitutes a rewriting means for obtaining the date of the specified month of the specified week based on the calculation result and rewriting the date specification in the date specification field.
An updating means is configured to add a shift of the day of the next month, which is set in advance, to the number assigned to the day of the first day, and obtain and update the day of the first day of the next month.

Therefore, according to the above embodiment, the date can be obtained by inputting the designated day of the week and the week, and the date automatically updated every month can be obtained. Is rewritten, schedule control can be performed based on the designation of a biweekly day of the week, and the designation of a date can be stored without increasing the memory capacity.
