Equipped with tsuh 'F' luck etc., the driver can now select and listen to the desired music source. In this case, is the selection of 8 music sources 1131J installed in the sound system? This is done by operating a switch for selecting a source.In this way, a plurality of music sources can be switched and selected.This sound device is disclosed in, for example, Japanese Patent Application Laid-Open No. 5698100, Publications, etc. However, it is already known that it is not practical.

By the way, as this type of acoustic music source, in addition to FM radio, AM radio, Kahichi 1 ~ Detsuki, etc., there is a recent tendency for televisions and so-called -81 discs to be equipped. There is a possibility that other sources will be added in the future.

However, when these sources are installed in a multi-tone TZ equipment, there is a problem of how to provide a selection switch for selecting the music source that the player wants to listen to. I'51: Providing a selection switch for each source requires a large number of switches, which is inappropriate for vehicles with limited space. When the driver operates the vehicle, there is a risk of making a mistake in the driving operation even though there are warnings ahead. As an alternative to this, there is one selection switch (Jl, for example, a push button l) which is applied to each source, and the switch fσ month %:
4'+ is repeatedly changed to J, and the music sources are changed to 1 in sequence.

Then, when any music source selection switch 16 is pressed, in step P5, the logic unit 5 reads out the frequency numbers of each of the music sources 6 to 10 stored in the memory unit 4, and selects the sum of each frequency number, that is, the stored frequency number. Check whether the number of data is 50 or more, and if the number of data is 50 or more, step P
Execute step 6. In this step P6, the logic unit 5 selects the music source 6 to 10 stored in the memory unit 4 according to the automatic selection order, which is arranged in descending order of the frequency of the music sources 6 to 10, which is the highest frequency? Send a switching signal 4':3S6 to the source switching circuit 12 so as to connect an east source, for example, FM radio 6 to the speaker set 11 corresponding to the music source selection switch 16. With one operation of the selection switch 1G, the music source that the user tends to most admire will be played from the music source 11 of the speaker 7J in question. After that, return to step P1 again, [1S+varnish-

Next, this subroutine will be explained.

First, go to steps Q1, Q2, and check the ON state of the accessory switch 1 and the top selector switch 13.
If the reset switch 17 is turned on and the mode changeover switch 13 is set to the manual (-) side, it is further determined whether the reset switch 14 is pressed in the snow pump Q3. If the reset switch 14 is not pressed, it is determined in step Q4 in 111 whether one of the music source selection switches 1G...16 has been pressed, and if any of the music source selection switches 16 is pressed. , the suite Q5 is executed.This step 05'c logic unit 5 selects the preset manual selection order (i'/'s first
A signal S6 is sent to the source switching circuit 12 so that the music source located at number 1 is connected to the speaker 11 corresponding to the music source selection switch 16.

As a result, the first (most preferred) music source in the manual selection order will be played from Subino J's set 11. In this case, when the music source selection IJVl switch /16 is pressed again, the second and subsequent music sources will be selected in manual order (according to l) each time.
