DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for an electronic device such as an in-vehicle audio device, and is used for a compact cassette reproducing device such as an FF / FF.
Related to REW operation.

[0002]

2. Description of the Related Art An on-vehicle audio system equipped with a conventional compact cassette reproducing apparatus will be described with reference to FIG.

FIG. 3 shows an FF of a conventional compact cassette.
A processing flow when the mode is switched during the REW / SCAN operation is shown. Step 31 in FIG.
And the compact cassette is in FF (REW, SCAN) operation. If it is determined in step 32 that the mode switching key has been operated, the FF (REW, SCAN) operation of the compact cassette is stopped in step 33, and step 3
At 4, the operation of the audio device other than the compact cassette reproducing device is started.

[0004]

However, if the conventional FF / REW / SCAN operation of the compact cassette is switched to a mode other than the cassette mode such as radio broadcast reception and compact disk reproduction during the operation, the FF / REW / SCAN operation of the compact cassette is performed. There is a problem that the REW / SCAN operation stops.

The present invention has been made to solve the above-mentioned conventional problems.
Even if you switch to a mode other than the cassette mode during N operation,
It is an object of the present invention to provide an audio device capable of continuing the FF / REW / SCAN operation of the compact cassette.

[0006]

SUMMARY OF THE INVENTION According to the present invention, there is provided a compact cassette FF / REW / SC.
Control means for continuing the FF / REW / SCAN operation of the compact cassette even if it is determined that the mode switching key is operated during the AN operation. FF ・ REW ・ S of compact cassette
It is characterized in that control different from that of the CAN operation is performed.

[0007]

Therefore, according to the present invention, by switching to a mode other than the cassette mode during the FF / REW / SCAN operation of the compact cassette, the F of the compact cassette is heard while listening to a source other than the compact cassette.
This has the effect that the F.REW.SCAN operation can be completed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS.

FIG. 1 is a part of a circuit configuration block diagram of an on-vehicle audio device having a compact cassette reproducing device. 11 is a compact cassette reproducing device, 12 is a compact disk reproducing device, 13 is a radio receiver for receiving a radio broadcast, 14 is a compact cassette reproducing device 1
FF / REW key for fast forward and rewind 1
Reference numeral 15 denotes a SCAN key for causing the compact cassette reproducing device 11 to perform a cueing operation, 16 denotes a mode switching key for switching the operation of each device, and 17 denotes a control circuit for controlling the operation of each device. The control circuit 17 is composed of a microcomputer or the like. Even if it is determined that the mode switching key is operated during the FF / REW / SCAN operation of the compact cassette, the FF / REW / SCAN operation of the compact cassette is continued. Is controlled.

Next, the operation of the above embodiment will be described.
FIG. 2 shows a processing flow of the control circuit 17.
In FIG. 2, in step 1, the compact cassette is FF
One of REW and SCAN is operating. If it is determined in step 2 that the mode switching key 16 has been operated, in step 3 the mode is switched to a mode other than the cassette mode. In step 4, the compact cassette is FF (REW)
It is determined whether the operation is in progress or the SCAN operation is in progress, and FF (REW)
If it is determined that the operation is being performed, the FF (REW) operation of the compact cassette is continued in step S5. In step 6, it is determined whether or not the compact cassette has been wound. If it is determined that the compact cassette has not been wound, the process returns to step 5. If it is determined in step 6 that the compact cassette has been wound, in step 7 the FF (RE
W) The operation is terminated, and the compact cassette reproducing device is stopped in step 8. If it is determined in step 4 that the compact cassette is performing the SCAN operation, the SCAN operation of the compact cassette is continued in step 9. In step 10, it is determined whether or not the cue of the compact cassette has been performed. If it is determined that the cue has not been performed, the process proceeds to step 9
Return to If it is determined in step 10 that the compact cassette has been located, the SCAN operation of the compact cassette is terminated in step 11, and the compact cassette reproducing device is stopped in step 12.

As described above, according to the above embodiment, even if it is determined in step 2 that the mode switching key has been operated,
There is an advantage that a mode other than the cassette mode (for example, radio reception) can be switched while the FF / REW / SCAN operation of the compact cassette is continued.

[0012]

According to the present invention, as is apparent from the above embodiment, the audio device can be switched to any mode while the FF / REW / SCAN operation of the compact cassette is continued. The FF / REW operation of the compact cassette is performed while listening to the sound, and the compact cassette can be taken out of the audio device after being wound up, or the SCAN operation of the compact cassette can be performed while listening to the source other than the compact cassette, and then the compact cassette When listening to music, it has the effect that playback can be started from the beginning of the music.
