Here, the signal processing circuit 42 selector 16
, 18, and switches the signal operation according to the type of the selection signal. As a result, when the compact disc player 4 , 6 , 8 is selected, the signal processing circuit 42 amplifies the audio signal output from the compact disc player 4 , 6 , 8 , and then outputs the amplified audio signal to the speaker 20 .

At this time, the signal processing circuit 42
The sound quality, volume, etc. are switched according to the output data of 0. On the other hand, when the television tuner 10 or the video tape recorder 12 is selected, the signal processing circuit 42
The audio signal output from the television channel 10 or video tape recorder 12 is output to the speaker 20, the video signal is processed, and the monitor device 1
Output to 4.

[0037] Thereby, the signal processing circuit 42 is configured to be able to monitor audio signals and video signals under conditions desired by the user.

On the other hand, when the display mode switching operator 32 is operated, the control circuit 40 switches and controls the display on the display section 31, thereby controlling the header unit 2.
, the current time and the like can be checked via the display section 31. At this time, the control circuit 40 outputs control data to the signal processing circuit 42 in response to the user's operation, so that the current time and the like can be confirmed even through the monitor device 14.

Furthermore, in the control circuit 40, when the terminal device switching operators 34A to 34D are operated, control data COM is output to the serial bus BUS, and thereby the terminal devices 4 to 34D connected to the serial bus BUS are outputted. 18
Switch the operation.

Furthermore, in the header unit 2, the remote commander 46 is operated to switch and control the operation of the audio apparatus 1 as a whole. In other words, header unit 2
receives a remote control signal from a remote commander 46 at a remote control receiver 44 and outputs a received signal SRE to the control circuit 40.

Based on the received signal SRE, the control circuit 40 outputs control data in the same manner as when the operators 32 to 38 are operated, and thereby controls the overall operation in response to the operation of the remote commander 46. It is designed to be switchable.

(3) Shuffle mode Here, the control circuit 40 selects the shuffle mode selection operators 36H to 36 while the operator 34D is pressed and the compact disc players 4, 6, and 8 are selected.
When J is pressed, the processing procedure shown in FIG. 4 is executed,
This switches the operation of the audio device 1 to the shuffle mode. When the normal playback operator 36G is pressed, the control circuit 40 enters the normal playback mode and plays the compact disc selected by the user.

In other words, the operator 3 for selecting the shuffle mode
When 6H to 36J are pressed, the control circuit 40 moves from step SP1 to step SP2, outputs control data COM to the compact disc players 4, 6, 8 and selectors 16, 18, and controls the entire audio device 1. Start the operation mode to playback mode.

Next, the control circuit 40 moves to step SP3, and determines whether or not the pressed operator is the operator 36H, so that the user can perform the in-disk shuffle (that is, select songs for the compact disc selected by the user). If a positive result is obtained, the process moves to step SP4. At this time, the control circuit 40 determines in which compact disc player the compact disc selected by the user is stored, and if the compact disc is not set at the playback position, it outputs a control signal COM to play the compact disc. to the play position.

In this state, the control circuit 40 performs step SP
At step 4, a song selection operation is performed for the compact disc set at the playback position, and the process moves to step SP5. Here, the control circuit 40 determines whether or not the selected song is included in the 10 songs selected so far, and if a negative result is obtained here, the process moves to step SP6.

[0046] Here, the control circuit 40 determines whether or not the compact disc is currently being played back, and in this case, if a negative result is obtained, the control circuit 40 moves to step SP7 to start playing the selected song, and then proceeds to step SP7. Return to SP3. As a result, in the audio device 1, when the user presses the operator 36H, a randomly selected song is played on the compact disc specified by the user.

Thus, the control circuit 40 returns to step S.
Processes P3-SP4-SP5 are executed, and in this case, the next song to be played is selected for the compact disc being played. Further, when the next song to be played is selected, the control circuit 40 repeats step SP6 when an affirmative result is obtained in step SP6, and when the song currently being played is finished, the control circuit 40 moves to step SP7 and selects the selected song. Then play.

As a result, the control circuit 40 performs steps SP3-SP4-SP5-SP6-SP7-SP3.
By repeating the processing loop LOOP1, randomly selected songs are sequentially played back on the compact disc selected by the user. At this time, when it is determined in step SP5 that the selected song is included in the 10 songs selected so far, the control circuit 40 returns to step SP3 and performs the song selection process again, thereby randomly selecting the selected song. Even when a song is selected, the same song is not played repeatedly.

[0049] Thus, in the audio device 1, by repeating the processing loop LOOP1, the shuffle function can be realized for the compact disc specified by the user.

On the other hand, if the operator 36I or 36J is pressed, the control circuit 40 obtains a negative result at step SP3, and proceeds to step SP8.

[0051] Here, the control circuit 40 determines whether or not the operator 36I has been pressed, thereby allowing the user to select a magazine shuffle mode (that is, a mode in which the music selection process is repeated for the compact disc player selected by the user). Decide whether you did or not.

If a positive result is obtained here, the control circuit 4
0 starts up the compact disc player selected by the user into the playback mode, and then moves to step SP9 to determine whether or not the compact disc player is a single player. In other words, the audio device 1 can be connected not only to a compact disc player in which a magazine can be set, but also to a compact disc player called a single player.

[0053] Therefore, since only one compact disc is stored in the single player, in the audio device 1, when such a single player is selected, shuffling within the magazine becomes difficult. Therefore, in the control circuit 40, step SP9
If a positive result is obtained in step SP4, an intra-disc shuffle operation is executed for the compact disc set in the single player.

[0054] As a result, in the audio device 1, even if the user mistakenly selects the single player and the magazine shuffle, the playback operation can be repeated without the user being aware of the mistake, and the audio device 1 can repeat the playback operation without making the user aware of the mistake. Designed to improve usability.

On the other hand, if a negative result is obtained in step SP9, the control device 40 proceeds to step SP10.
Then, for the compact disc player selected by the user, a compact disc is randomly selected from the magazine of the compact disc player. Furthermore, if the selected compact disc player is not set to the playback mode, the control circuit 40 outputs a control signal to the selected compact disc player to set it to the playback mode.

Furthermore, the control circuit 40 controls the control data C when the selected compact disc is not set at the playback position in the compact disc player.
OM is output and the compact disc is set at the playback position.

Next, the control circuit 40 moves to step SP4, and executes a music selection operation for the compact disc selected here. As a result, in the control circuit 40, when the operator 36I is pressed, the process proceeds to step SP3.
-SP8-SP9-SP10-SP4-SP5-SP6
- The processing loop of SP7-SP3 is repeated, thereby randomly selecting a compact disc for the compact disc player designated by the user, and performing music selection work on the selected compact disc.

Further, the control circuit 40 reproduces the selected song through this series of operations and then repeats the subsequent series of song selection operations, thereby realizing the intra-disk shuffle function.

On the other hand, if a negative result is obtained at step SP8, the control circuit 40 moves to step SP11 and randomly selects the compact disc players 4, 6, and 8 of the audio device 1, and then returns to step SP11.
Move on to 9. As a result, in the control circuit 40, when the operator 36J is pressed, steps SP3-SP8 are executed.
-SP11-SP9-SP10-SP4-SP5-SP
After repeating the processing loop of 6-SP7-SP3 to randomly select a compact disc player, a compact disc is randomly selected for the selected compact disc player, and a music selection operation is further performed for the selected compact disc.

Furthermore, the control circuit 40 reproduces the music selected by this series of operations and repeats the series of music selection operations, thus making the compact disc players 4, 6,
8 as a whole can realize a shuffle function.

[0061] Therefore, by pressing the operator 36J in this way, the user can easily operate multiple compact disc players without being aware of what kind of compact disc is stored in each compact disc player. The audio device 1 can be operated without being aware that it is connected, and the usability of the audio device 1 can be improved accordingly.

In this embodiment, when the skip operator is pressed, the control circuit 40 switches to step SP.
The process in step SP6 is jumped and the process in step SP7 is executed, whereby in response to the user's operation, the next selected song is played without waiting for the end of the song being played. As a result, if the user selects a song that he or she does not want to listen to, he or she can interrupt the playback of that song simply by pressing the skip operator.

(4) Operation of the embodiment In the above configuration, when the selection operator 34G of the compact disc player is pressed, the audio device 1
, the control data C output from the control circuit 40
Based on the OM, the compact disc player 4, 6, or 8 selected by the user is switched to the playback mode, and a playback operation is started for the compact disc 22 desired by the user.

On the other hand, when the operator 36H is pressed, the control circuit 40 in the audio device 1 performs steps SP3-SP4-SP5-SP6-SP7-SP.
After the compact disc selected by the user is set at the playback position by sequentially executing the processing steps in step 3,
Randomly selected songs are sequentially played on the compact disc.

[0065] This makes it possible to implement a shuffle mode for the compact disc selected by the user, thereby improving the usability of the audio device.

On the other hand, when the operator 36I is pressed, the control circuit 40 in the audio device 1 performs steps SP3-SP8-SP9-SP4-SP5-SP.
By sequentially executing the processing steps 6-SP7-SP3, a compact disc is randomly selected from the magazine of the compact disc player selected by the user. Further, in the audio device 1, after the selected compact disc is set at the playback position, a randomly selected song is played on the compact disc.

[0067] As a result, in the audio device 1,
