Abstract

PURPOSE: To provide an on-vehicle acoustic device capable of FF and REW operations even though this device is in modes other than a cassette mode. CONSTITUTION: In the acoustic device on vehicle provided with a compact cassette redroducing device 11, a compact disk reproducing device 12, a radio receiver 14, etc., a control circuit 15 controls devices so that operations of the FF and the REW keys 12 are made effective even in modes other than a compact cassette redoducing mode. Thus, the fast forwarding or the rewinding of the tape of the compact cassette is made possible.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in electronic equipment such as on-vehicle audio equipment, and is used as a compact cassette player FF.
Regarding the REW operation.

[0002]

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

FIG. 3 shows a conventional compact cassette FF.
-The processing flow of the REW operation is shown. In FIG. 3, when it is determined in step 31 that the FF key (or REW key) has been operated, it is determined in step 32 whether the current state of the audio device is the cassette mode. The cassette mode indicates a state in which a compact cassette is selected from a plurality of sources such as compact disc radio. If it is determined in step 32 that the cassette mode is not set, it is determined in step 33 that the operation of the FF key (REW key) is invalid. If the cassette mode is determined in step 32, the FF of the compact cassette is determined in step 34.
(REW) operation is started. In step 35, 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 34. Step 3
If it is determined in step 5 that the compact cassette has been wound up, in step 36 the FF (RE
W) The operation is ended, and in step 37, the reproduction of the compact cassette is started.

[0004]

However, the FF / REW operation of the conventional compact cassette described above is
Since the REW key is valid only in the cassette mode, FF / RE can be used while receiving a radio broadcast or playing a compact disc.
There is a problem that the W operation cannot be started.

The present invention solves the above-mentioned conventional problems, and provides an audio device capable of FF / REW operation of a compact cassette in any mode other than the cassette mode.

[0006]

In order to achieve the above object, the present invention is provided with a control means for making the operation of the FF / REW key effective in a mode other than the cassette mode. FF when not in mode
This is characterized in that different control is performed depending on the REW operation.

[0007]

Therefore, according to the present invention, the FF / RE of the compact cassette can be used in any mode of the audio device.
By performing the W operation, it is possible to wind the compact cassette while listening to the sources other than the compact cassette.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An 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 equipped with a compact cassette reproducing device. 11 is a compact cassette reproducing device, 12 is a FF / REW key for fast-forwarding and rewinding the compact cassette reproducing device 11, 13 is a compact disc reproducing device, 14 is a radio receiver for receiving a radio broadcast, and 15 is It is a control circuit for controlling the operation of the above device. The control circuit 15 is composed of a microcomputer, etc.
・ The REW key operation is enabled and the control different from that in the cassette mode is performed.

Next, the operation of the above embodiment will be described. FIG. 2 shows a processing flow of the control circuit 15. In step 21, the FF / REW key 12 FF key (REW
If it is determined that the key) has been operated, it is determined in step 22 whether the current state of the audio device is the cassette mode. If it is determined in step 22 that the cassette mode is selected, the processing from step 23 onward is performed. The cassette mode indicates a state in which a compact cassette is selected from a plurality of sources such as compact disc radio. Step 23
When the FF (REW) is operated in step S23, it is determined in step S25 whether or not the compact cassette is wound up. If it is determined that the compact cassette is not wound up, the process returns to step S23. If it is determined in step 25 that the compact cassette is wound up, in step 26, the FF (RE
W) The operation is ended, and in step 27, the reproduction of the compact cassette is started.

If it is determined in step 22 that the cassette mode is not set, in step 24 the F of the compact cassette is read.
F (REW) operation is started. In step 28, 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 24. If it is determined in step 28 that the compact cassette has been wound up, in step 29 the FF (RE
W) The operation is completed, and the tape running of the compact cassette is stopped in step 30.

As described above, according to the above embodiment, the FF (REW) operation of the compact cassette can be performed even when it is determined in step 22 that the cassette mode is not set (for example, during compact disc reproduction). It has the advantage of being able to.

[0013]

As is apparent from the above embodiment, the present invention is as follows.
The FF / REW operation of the compact cassette can be performed in any mode of the audio device, and the FF / REW operation of the compact cassette is performed while listening to the source other than the compact cassette to wind the compact cassette. It has an effect that it can be taken out from the audio device after being taken.
