2), it is selectively activated. The user's mode and other specifications can be made from the operation panel (10) to the control circuit (22).
) to command the reception or playback status of either the radio or DAT.

The control circuit (22) includes a CPU (23) and executes each command control, and the audio playback unit (20) of the present invention is capable of cueing an arbitrary program among a plurality of recorded programs. The CPU (23) can instruct the audio playback section (20) to perform such high-speed search or cue playback.

On the other hand, as mentioned above, the radio receiving section (21
) allows one-touch tuning using a plurality of tuning keys, so the predetermined tuning memory (24) is provided in the control circuit (22). The receiving stations preset by the aforementioned channel selection key (15) are stored in the memory (24) in a plurality of storage units (24a), (24b), (

That is, in the embodiment, the channel selection key (15) is set to "1".
”, you can skip one station and press the selection key (1
When 5) is "6", 6 stations are skipped.

FIG. 1 shows the program skip function of the channel selection key of this embodiment. While the device is operating, it is determined whether it is in radio reception mode or audio playback mode (
101), in audio playback mode, set the number of channel selection key operations K and the number of program skips NS to 0 (102)
). In this audio playback mode, the control circuit (
22) always monitors the operation of the channel selection key (15) (103).
), (104), when the user presses any of the channel selection keys (15), "1" is added to the number of times K (10
5). Next, in step 108, it is determined whether the number of times K is the first or second time, and if it is the first time, the individual number of the channel selection key (15) pressed at this time, that is, the channel selection key number, is Read from memory given for each time (1
06), and the number of program skips N1 predetermined by the control circuit (22) corresponding to this channel selection key number.
is read out (107). As described above, in this embodiment, this number of skips matches the individual number given to each music selection key (15).

Next, in step 109, a predetermined time is counted; in the embodiment, this count time is set to, for example, 0.5 seconds, and steps 103 to 109 are repeated until the predetermined time elapses ( 1
10). In the embodiment, this predetermined time is such that when the channel selection key is pressed twice in succession, skipping is performed in descending order;
When only the turn is pressed, it is used to switch to skip in ascending order. Therefore, when the channel selection key is operated for the first time, the process returns from step 110 to steps 103 and 104, and since K=1 at this time, time counting continues through step 111 and continues for a predetermined 0.5 seconds. If the second channel selection key operation is not performed, this is determined to be an instruction to skip in ascending order, and in step 112, programs are skipped in ascending order by the number of skips determined by the channel selection key. After this skip is completed, the process returns to step 102 and waits for the next channel selection key operation.

On the other hand, if the channel selection key is pressed again during the predetermined time count in step 103, the number of times K becomes "2".
(105), and since K=2 in step 108, the process advances to step 113.

At step 113, it is determined whether or not the two consecutively operated channel selection keys are the same. If they are the same, at step 114 the programs are programmed in descending order by the number of skips specified. Skip. On the other hand, if the second channel selection key pressed within the predetermined time is different from the previous one, detection of the second channel selection key number pressed (116);
The skip number corresponding to this number is read out (117
), it is determined that ascending order skip has been instructed twice in a row, and
Add the number of program skips N1 according to the first instruction and the number N2 of programs according to the second instruction (118),
Program skips are performed in ascending order by the number of skips resulting from the addition (112). Therefore, according to the present invention, it is possible to very easily specify a program skip during audio reproduction using a radio reception tuning key, and select a desired program.

In the embodiment, the program skip direction is determined by one or two channel selection key operations within a predetermined time, but in the present invention, only ascending order or descending order is selected. It is also possible to skip by the number of the key that was entered, in which case step 10 can be skipped without the need for time counting in the embodiment.
The program may be skipped in ascending or descending order by the number of skips read from 7.
