A switch input circuit unit 3 for receiving an input signal of an operation button, an operation panel surface 4 on which operation switches are arranged, and a display device 5 arranged on the operation panel surface 4
(A liquid crystal display, an LED display, etc.), a frame 6 disposed on the back of the operation panel surface 4, and a plurality of connectors (first connector 7, first connector 7) for electrically connecting the selected audio equipment units A1, B1 respectively. A second connector 8, a third connector 9), and a first connector 7 ′ via a base unit 10 attached to an instrument panel (not shown) of the vehicle and the first connector 7 attached to the base unit 10. (7 and 7 'are the relationship between male and female, and so on.)
One audio equipment unit A1 in a first audio equipment unit group (hereinafter referred to as module A) which can be detachably attached to the device (by means such as screwing, etc.).
And a second audio equipment unit group (hereinafter referred to as module B) which is detachably attachable to the frame 6 while being electrically connected to the second connector 8 'via the second connector 8 disposed at another position. One audio equipment unit B in
And a radio tuner unit C which can be detachably attached to the frame 6 while being electrically connected to the frame 6 via the third connector 9 'via the third connector 9.
The system is configured such that any combination of an audio equipment unit and a radio tuner unit C can be selected from the module and the module B (corresponding to claim 2).

For example, a CD player unit (A1) and a CD changer unit (A2) are prepared in module A, and an MD player unit ( B1) and a compact cassette deck unit (B2) are prepared, and a radio tuner unit C is prepared separately therefrom. Units in the same module have the same dimensions, and connectors (7 'or 8') are arranged at equivalent positions and can be replaced. However, units of different modules are configured to have different connector positions. If the modules are different, they will not fit properly with the connector 8 or 9, so that there is no erroneous mounting. (Corresponding to claim 3). The arrangement of the connectors 8 and 9 in the base unit 10 may be attached to the rear of the operation panel surface 4 as shown in FIG. May be arranged differently.

Further, the operation panel surface 4 of the base unit 10 has a slit hole 11 for inserting and removing a compact disk which can be easily opened later by a user himself and a slit hole 12 for inserting and removing a mini disk which can be easily opened later. And at least one of the slit holes for insertion and removal of the compact cassette that can be easily opened (shared with the slit hole 12 in FIG. 1) is disposed with the surface of the opening part closed.

For example, there is a method in which the panel surface is slightly connected to the operation panel surface 4 from the back surface by one opening edge so that the panel surface of the opening portion remains, or the opening portion is completely opened and the opening portion is closed. There is a method of covering with a thin lid from the front side of the operation panel surface.

By installing the MD player unit (B1) while connecting it to the connector 8 or 9 from the rear side of the panel surface 4, the car audio system which initially only had AM / FM radio was later changed to the convenience and preference of the user. , A CD player or a CD changer and an MD player or a compact cassette deck can be arbitrarily selected and combined. Of course, FIG.
, Only the upper module A, for example, only the CD player (A1) can be added to the system. In this case, it may be desirable to reinforce the fixation to the frame 6. Note that the module A and the module B are electrically connected to the base unit 10 via the first connector 7 and the second connector 8 independently and electrically. Also,
As described above, the positions of the connectors 7 to 9 can be appropriately designed. In FIG. 1, the positions are on the back side of the operation panel surface 4. However, the present invention is not limited to this. It may be arranged.

According to the above configuration, even when initially used as an audio system having only the radio tuner unit C, a design design of the operation panel surface 4 having a 2DIN size body or a variant shape of a larger size is adopted.
Thereafter, since the slit hole 11 for inserting and removing the compact disk and the slit hole 12 for inserting and removing the mini disk for closing up the system as described above are closed, the appearance is good.

Next, an on-vehicle audio equipment unit system 3 according to claim 1 of the present invention shown in FIG.
0 is a system in which one or both of the first audio equipment unit group (module A) and the second audio equipment unit group (module B) include the radio tuner units Ax and Bx so as to be selectable. is there. In this case, the radio tuner units Ax and Bx may be a single unit, or may be incorporated in another unit such as an MD player with a built-in tuner or a CD player with a built-in tuner.

It should be noted that, in the on-vehicle audio equipment unit system 20 shown in FIG. 1, the operation panel surface 4 has a size conforming to the 2DIN size. It should be understood that the size of 4 is not particularly limited, and that a 2DIN size or larger irregular size is more versatile in system up. In the present invention,
The size of the operation panel surface 4 and the front size of the modules A and B mounted behind the operation panel surface 4 do not always match. For example, the modules A and B hidden behind the operation panel may be larger or smaller than the size of the operation panel surface attached to the front of the instrument panel. Further, it is not necessary to unify the depth dimension of each unit.

As described in detail above, in the on-vehicle audio device unit system of the present invention, the user can arbitrarily select and combine his or her favorite audio devices based on the base unit when the system is convenient.
There is no doubt that it is a truly user-oriented invention.
