That is, When the jog dial 22 is pressed while the cursor arrow 2 3 1 is in the selection mode of the item (3), the CPU processing of the microcomputer 20 is executed. Starting from 1, then in step 202, the data in the data table 31 is sorted in chronological order by comparing the time "hour”.
- step 203 the data table 31 that has been rearranged in step 202 is further rearranged with priority given to the current time and day of the week. Then, in step 204, the same processing as in routine 100 is performed using the data table 31 and the data table 33 obtained as a result of step 203, and channel selection is performed. At step 205, the routine 200 ends.
- step 203 can be configured, for example, as a routine 300. That is, in the routine 300, the process starts from step 301, and then, in step 302, the current time and day of the week data are obtained from the clock circuit 25. In, a pointer is set in the data field of the data table 31 (FIG. 3A), in the “time” column of “hour”, which is the same as the “hour” of the current time acquired in step 302.
- step 304 of the data in the data table 31, data located from the first column to the data column preceding the pointer set in step 303 is stored in the data table 31. Is moved to the end. Then, in step 305, the data of the data table 31 processed in step 304 is compared with the data of the same “hour”, and the current day of the week acquired in step 302 is The order is sorted in the order of the day of the week so that the previous one is reached.
