To ensure an electric connection and a mechanical fixing, preferably two apparatus-side contact terminals are provided at the lower left side and the lower right side of the controller 4, respectively.

The audio apparatuses 5, 6, 7 have the external shapes formed in a rectangular solid shape, and have the legs 4l at four corners of the lower surface, like the controller 4. A depth size of the audio apparatuses 5, 6, 7 is set the same as the size of the controller 4 so that the apparatuses are inserted into the trenches 1a, 1b and are engaged with the trenches 1a, 1b.

As shown in FIG. 3-1 and FIG. 4, like the controller 4, at the lower left side of side surfaces 4m, 4n before and after the audio apparatuses 5, 6, 7, there are disposed total 13 apparatus-side contact terminals: apparatus-side power supply terminals b1, b2 as common terminals formed in a semispherical projection shape; an apparatus-side antenna terminal a; an apparatus-side GND terminal g as a common terminal; an apparatus-side video signal terminal v; an apparatus-side right audio signal terminal r; an apparatus-side left audio signal terminal l; apparatus-side control signal terminals c1, c2, c3 as exclusive signal terminals for the audio apparatuses; and apparatus-side data signal terminals d1, d2, d3 as exclusive signal terminals for the audio apparatuses, in the same height as that of the rack-side contact terminals, respectively, and these apparatus-side contact terminals are contacted and electrically connected to the rack-side contact terminals.

As shown in FIG. 5, in the tuner 5, the apparatus-side power supply terminals b1, b2 and the apparatus-side antenna terminal a as common terminals, the apparatus-side GND terminal g as a common terminal, and the apparatus-side control signal terminal c1 and the apparatus-side data signal terminal d1 as exclusive signal terminals for the tuner 5 are the apparatus-side contact terminals that are electrically connected to the inside of the tuner 5. Other terminals are dummy terminals to fix the tuner 5 to the trenches 1a, 1b.

In the CD player 6, the apparatus-side power supply terminals b1, b2 and the apparatus-side GND terminal g as common terminals, and the apparatus-side control signal terminal c2 and the apparatus-side data signal terminal d2 exclusive for the CD player 6 are the apparatus-side contact terminals that are electrically connected to the inside of the CD player 6. Other terminals are dummy terminals to fix the CD player 6 to the trenches 1a, 1b.

In the DVD player 7, the apparatus-side power supply terminals b1, b2 and the apparatus-side GND terminal g as common terminals, and the apparatus-side control signal terminal c3 and the apparatus-side data signal terminal d3 exclusive for the DVD player 7 are the apparatus-side contact terminals that are electrically connected to the inside of the DVD player 7. Other terminals are dummy terminals to fix the DVD player 7 to the trenches 1a, 1b.

As explained above, in the audio apparatuses 5, 6, 7, the apparatus-side power supply terminals b1, b2 and the apparatus-side GND terminal g are common terminals provided in common to the audio apparatuses 5, 6, 7, and the apparatus-side control signal terminals c1, c2, c3 and the apparatus-side data signal terminals d1, d2, d3 are signal terminals exclusive for the audio apparatuses. In the rack-side connector 20, rack-side control signal terminals and rack-side data signal terminals are installed corresponding to the number of connected audio apparatuses.

The rectangular solid shape lower part of the controller 4 and the audio apparatuses 5, 6, 7, including the legs 4l becomes a supported part 21 that is supported by being engaged with the trench 1a. The supported part 21 and the apparatus-side contact terminals disposed on the side surfaces before and after the supported part 21 constitute an apparatus-side connector 22.

When the supported parts 21 of the controller 4 and the audio apparatuses 5, 6, 7 are inserted into and engaged with the trenches 1a, 1d as long supporting units, the apparatus-side connectors 22 are connected to the rack-side connector 20. Because the belt-shaped rack-side contact terminal extends along approximately the whole length of the trenches 1a, 1d, the controller 4 and the audio apparatuses 5, 6, 7 can be installed at free optional positions of the trenches 1a, 1d, and these positions can be continuously moved.

As shown in FIG. 3-2, the lower parts of the display 2 and the speakers 3a, 3b have a depth size smaller than the width of the trenches 1a, 1d, and a disk-shaped frame 2a is provided to protect falling.

In the display 2, the apparatus-side power supply terminals b1, b2, the apparatus-side GND terminal g, and the apparatus-side video signal terminal v are apparatus terminals that are electrically connected to the inside of the display 2. Other terminals are dummy terminals to fix the display 2 to the trenches 1a, 1d.

In the speakers 3a, 3b, the apparatus-side GDN terminal g, and the apparatus-side right audio signal terminal r or the apparatus-side left audio signal terminal l are apparatus-side terminals that are electrically connected to the inside of the speakers 3a, 3b. Other terminals are dummy terminals to fix the speakers 3a, 3b to the trenches 1a, 1b.

A method of electrically connecting the controller 4 to the display 2 and the speakers 3a, 3b via the rack-side connector 20 is explained above. The display 2 and the speakers 3a, 3b do not require a frequent change of their installation positions on the audio rack body 1. Therefore, the display 2 and the speakers 3a, 3b can be fixedly installed on the audio rack body 1, instead of providing the trench 1d. The controller 4 can be electrically connected to the display 2 and the speakers 3a, 3b by directly connecting between them by wire, without via the rack-side connector 20 and the apparatus-side connector 22. While the trench 1a is explained as a long continuous trench, instead of this, plural short trenches into which the audio apparatuses 5, 6, 7 can be inserted separately can be provided.

Next, another example of the rack-side connector and the apparatus-side connector is explained with reference to FIG. 6 and FIG. 7. As shown in FIG. 6, a trench 1e having a smaller width than the width of the trench 1a is provided at the center of the trench 1a of the audio rack body 1, over the whole length of the trench 1a. A rack-side pin connector 25 connected to a multi-line cable 27 is provided, instead of the rack-side connector 20, within the trench 1e. Plural rack-side pin connectors 25 are provided corresponding to a maximum installed number of audio apparatuses, and the rack-side pin connectors 25 are inserted into and connected to apparatus-side pin connectors 26 provided at a lower part of the audio apparatuses 5, 6, 7, respectively, with the multi-line cable 27 bent in a U-shape as shown in FIG. 7. The apparatuses are electrically connected in the same manner as that shown in FIG. 5.

When the multi-line cable 27 is bent in a U-shape, the audio apparatuses 5, 6, 7 can be installed at optional positions on the trench 1a, and the installation positions can be moved continuously. The display 2 and the speakers 3a, 3b can be also connected to the controller 4 based on this connection form. According to this connection form, the apparatuses are connected using the multi-pin cable 27 and the pin connectors 25, 26. Therefore, the electrical connection has high reliability.

Next, assembling and operation of the audio system 100 are explained. First, the display 2, the speakers 3a, 3b, the controller 4, and the audio apparatuses 5, 6, 7 are installed on the trenches 1a, 1d of the audio rack body 1. The apparatus-side connectors 22 (26) are connected to the rack-side connectors 20 (25). The power supply cord 10 is connected to the power supply, and the antenna cable 11 is connected to the antenna.

When the operation input unit 4i is operated to turn on the power supply to the controller 4, a connection apparatus identification program stored in a ROM 4e is started. When this connection apparatus identification program is operated, the change-over switch 4a is controlled to first connect the signal terminals C1, D1 of the tuner 5 to the controller 4, and measure the potential of the signal terminal C1 or D1. A power supply to the tuner 5 is on through the apparatus-side power supply terminals b1, b2. Therefore, a predetermined potential V1 corresponding to the internal resistance of the tuner 5 is generated in the signal terminals C1, D1. When the predetermined potential V1 is generated, it is recognized that the tuner 5 is connected, and this effect is displayed in the display unit 4j. When the potential V1 is not generated, it is recognized that the tuner 5 is not connected.

Next, the changeover switch 4a is switched to connect the signal terminals C2, D2 of the CD player 6 to the controller 4. The potential of the signal terminal C2 or D2 is measured, and a connection or non-connection of the CD player 6 is recognized. When a predetermined potential V2 corresponding to the internal resistance of the CD player 6 is generated, it is recognized that the CD player 6 is connected. Similarly, a connection or non-connection of all connectable apparatuses is recognized, and the connectable and usable audio apparatuses 5, 6, 7 are displayed in the display unit 4j.

When a user operates the operation input unit 4i to select the CD player 6 displayed in the display unit 4j, the changeover switch 4a selects the signal terminals C2, D2, and connects the signal terminals C2, D2 to the general-purpose interface 4b of the controller 4. When the user carries out the start operation, a control signal is transmitted from the control signal terminal C2 to the CD player 6, thereby operating the CD player. A data signal is fetched from the data signal terminal D2, and the CPU 4c processes this signal. At least one of the audio processors 4f, 4g and the vide processor 4h outputs at least one of the audio signal and the video signal to at least one of the audio signal terminals R, L and the video signal terminal V, thereby operating at least one of the display 2 and the speakers 3a, 3b.

Other audio apparatuses 5, 7 can be also selected and operated in a similar manner to the above. The changeover switch 4a can be switched to connect the tuner 5 and the CD player 6 or the DVD player 7 to the controller 4, and data from the tuner 5 can be recorded in the CD disk 61 or a DVD disk 71.

The configuration and the operation of the audio system 100 are as explained above. The audio rack according to the first embodiment includes the plate-shaped audio rack body 1 having the trench 1a as a long supporting unit, the rack-side connectors 20 (25), and the controller 4, out of the constituent elements of the audio system 100. According to the audio rack of the first embodiment, plural audio apparatuses such as the tuner 5, the CD player 6, and the DVD player 7 can be installed at free and optional positions of the trench 1a of the audio rack body 1. Therefore, the wiring and connection operation at the time of setting the audio apparatuses 5, 6, 7, and the wiring and connection operation at the time of changing the layout of the apparatuses become easy.
