Reference numeral 5 denotes a receiving antenna of a receiving circuit unit 6 for AM broadcasting, FM broadcasting, short wave broadcasting, etc., and 7 denotes a tuning operation when the radio receiving section 8 is selected by a tuning button (not shown). This is a channel selection operation signal output unit that outputs a signal e indicating that the event has occurred.

Reference numeral 9 denotes a magnetic tape device such as a cassette, which will be described as a recording and reproducing device in this embodiment. That is, the audio signal f recorded on a cassette tape or the like
Or a music signal or the like input from the auxiliary input terminal 10 for voice input is input and recorded on the cassette tape.

Reference numeral 11 denotes a control unit (disk reproduction mode selection means, sleep timer time setting means) equipped with a microcomputer for controlling the entire audio device having a sleep function. The control unit 11 outputs the reproduction signal k output from the disc reproducing apparatus 1, the reception signal m output from the radio receiving unit 8 and the tape recording / reproducing apparatus 9 based on the operation signal output from the operation unit 12. A selection signal for selecting one of the selected music signals f is output. The control unit 11 also stores a program for sleep timer processing shown in the flowchart of FIG. The operation unit 12 is also provided with a sleep timer function selection key 12a and a disc reproduction mode selection key 12b for selecting a sleep timer function.

Based on the selection signal, the audio switching circuit 31 reproduces a reproduction signal k output from the disc reproducing apparatus 1, a reception signal m output from the radio receiving section 8 and a music output from the tape recording / reproducing apparatus 9. This is a circuit that selects one of the signals f.

The muting circuit 33 is the voice switching circuit 3.
A circuit provided on the output side of 1 for temporarily reducing the signal level selected by the audio switching circuit 31, and an amplifier circuit 34 amplifies the output signal of the muting circuit 33 to amplify the speaker 3
It is a circuit leading to 5. The amplifier circuit 34 is provided with a loudness control circuit, a graphic equalizer circuit, etc., which are not shown.

Next, the sleep timer function of the audio apparatus of this embodiment will be described with reference to the flowchart of FIG. When the sleep timer function selection key 12a of the operation unit 12 is operated in step S0, it is first determined in step S1 whether or not the disc reproduction mode is selected. This determination is made based on whether or not the disc reproduction mode selection key 12b of the operation unit 12 has been operated. When it is determined that the disc reproduction mode is selected, in the subsequent step S2, the maximum playing time T required to reproduce all the songs by making a round based on the song currently being reproduced, that is, the disc is recorded on the disc. The maximum playing time T required to reproduce all the songs from the first song to the last song is detected from the TOC of the disc. Further, the process proceeds to step S3, and the maximum performance time T detected in step S2 is preset in the sleep timer as the sleep time.
Then, in the subsequent step S4, the disc is reproduced while determining whether or not the maximum playing time T has elapsed, and when the maximum playing time T has elapsed, the power of the audio device is turned off.

On the other hand, when it is judged in step S1 that the disk reproduction mode is not selected and, for example, the tape reproduction mode such as a cassette is selected, the process proceeds to step S6, and the user sleeps in minutes as in the conventional case. Set the time by key operation.

As described above, in the present embodiment, when the sleep timer function is selected and the disc playback mode is selected, all the songs are played back once based on the song currently being played. The maximum playing time T required, that is, the maximum playing time T required to play all songs from the first song to the end recorded on the disc will be automatically preset as the sleep time in the sleep timer, The operation when using the sleep timer function is simplified, and the operability when using the sleep timer function is improved.

In this embodiment, the sleep timer time is set to the maximum playing time T of the disc. However, as another embodiment, as described below, the time until the final tune of the disc is finished is automatically set. It may be set. Specifically, in the program for the sleep timer processing shown in FIG. 2, the following replacement may be made. That is, in step S2 of FIG. 2, the time T'which is required from the song next to the song currently being played on the disc to the end of the final song on the disc is detected from the disc TOC. In the next step S3, this time T'is set in the sleep timer. If the program of FIG. 2 is replaced as described above, when the sleep timer function is set, the disc reproduction is always finished with the last song as a disc, regardless of which song is reproduced.
