In addition, when the apparatus 1 is installed in a wall-hanging state, the board support member 3 is installed in an orientation that is positioned on the lower side.
The substrate support member 3 is disposed in the vicinity of the periphery of the lower case 2, and the backboard substrate 4 is supported on a central surface (hereinafter referred to as a surface) of the lower case 2 by, for example, screwing. As a result, the backboard substrate 4 is erected almost vertically on the bottom surface of the lower case 2 in the same manner as the substrate support member 3.

Here, the backboard substrate 4 is formed with a height lower than that of the substrate support member 3. For this reason, the upper end portion 3 a of the substrate support member 3 is exposed from the backboard substrate 4 when viewed from the front, and the exposed portion sufficiently covers the surface of the backboard substrate 4 toward the center of the lower case 2. It is configured as a protruding portion 31 protruding beyond.
The protrusion 31 of the substrate support member 3 is formed with a plurality of (for example, six in the figure) cutouts 32 arranged in parallel in a direction extending along the horizontal. These notches 32 have an eight-letter shape whose interval narrows from the front surface to the back surface of the substrate support member 3. The notch 32 will be described in detail later.

A plurality (for example, six in the figure) of first connectors 5 are mounted on the backboard substrate 4 on the center side surface (hereinafter referred to as a surface) of the lower case 2. The first connectors 5 are arranged on the backboard substrate 4 in parallel in the width direction with the longitudinal direction being the vertical direction.
The first connectors 5 of the backboard substrate 4 are each electrically connected to a selection substrate 6 erected substantially perpendicularly to the bottom surface of the lower case 2.
A plurality of (for example, six in the figure) guide grooves 7 extending perpendicularly to the backboard substrate 4 are formed on the bottom surface of the lower case 2 so as to be juxtaposed in a direction perpendicular to the extending direction. The selection substrate 6 is positioned and arranged by inserting the lower end side of the selection substrate 6 into the guide groove 7.

In FIG. 1, one selection substrate 6 is inserted into one guide groove 7 and is inserted into one notch portion 32 formed in the protrusion 31 of the substrate support member 3, so that the lower case 2 is formed. It shows that they are arranged upright on the bottom.
FIG. 2 is a top view of the bottom surface of the lower case 2, and a notch 32 formed in the protrusion 31 of the substrate support member 3 is formed so as to be positioned above the guide groove 7 and has a predetermined guide. The selection substrate 6 inserted and disposed in the groove 7 is inserted into the corresponding notch 32 at the side edge on the substrate support member 3 side.

As shown in FIG. 3, the selection board 6 has a second connector 9 mounted on the side edge of the backboard board 4, and the second connector 9 is a single first board mounted on the backboard board 4. 1 connector 5 is adapted to be fitted. Electrical connection between the backboard substrate 4 and the selection substrate 6 is made by fitting the first connector 5 and the second connector 9 together. FIG. 3 is a perspective view of the periphery of the selection substrate 6 when the selection substrate 6 is viewed from the direction opposite to the direction shown in FIG.
Further, as shown in FIG. 2, the selection board 6 is attached with a mounting bracket 10 so as to come into contact with the bottom surface of the lower case 2 on the side edge opposite to the board support member 3. The screw 12 fixes the metal plate 11 fixed to the lower case 2. The mounting bracket 10 of the selection board 6 is connected to, for example, a ground terminal of the selection board 6, and this ground terminal is drawn out of the apparatus through the metal plate 11.

4 is a cross-sectional view taken along line IV-IV in FIG. As shown in FIG. 4, the engaged portion 14 that connects the opposing walls of the notch 32 is formed in the notch 32 formed in the protrusion 31 of the substrate support member 3. Further, a recessed portion 15 (sometimes referred to as an engaging portion in this specification) into which the engaged portion 14 is inserted is formed in a portion of the selection substrate 6 that is inserted into the notch portion 32. .
5 is a cross-sectional view taken along the line V-V in FIG. The selection substrate 6 shown in FIG. 5 is arranged so as to exist on the back of the protrusion 31 of the substrate support member 3. Thereby, it becomes apparent that the selection substrate 6 shown in FIG. 5 is inserted into the notch 32 formed in the protrusion 31 of the substrate support member 3.
FIG. 6 is a perspective view of the protrusion 31 of the substrate support member 3 as viewed obliquely from above. The engaged portion 14 (the selected substrate 6 is inserted in the figure) is inserted into the notch 32 formed in the protrusion 31. (The engaged portion 14 of the cutout portion 32 is not shown), and the selection substrate 6 is formed with a recess 15 (see FIG. 4) into which the engaged portion 14 is inserted. Becomes clear.

FIG. 7 is a view of the substrate support member 3 (with the backboard substrate 4 removed) as viewed from the front (the center side of the lower case 2), and is formed on the protrusion 31 of the substrate support member 3. Each notched portion 32 is formed with an engaged portion 14, and among these, the engaged portion 14 formed in the notched portion 32 at the right end in the figure is formed in another notched portion 32. It is formed at a position different in the vertical direction in the figure as compared with the engaged portion 14. Accordingly, the selection substrate 6 (see FIG. 6) inserted into the notch 32 at the right end of the substrate support member 3 in the figure also has a recess 15 (see FIG. 4) at a position corresponding to the engaged portion 14. It is comprised so that.
The reason for this configuration is that the selection substrate 6 inserted into the notch 32 at the right end in the figure of the substrate support member 3 is different in type from the selection substrate 6 inserted into the other notch 32. This is because it is possible to avoid misplacement of other different types of selection substrates 6 at the placement locations.
For this reason, the position of the engaged portion 14 formed in the notch 32 of the substrate support member 3 is not necessarily as shown in FIG. 7 and is different depending on the type of the selected substrate 6. You may make it provide.

In this case, the selection substrate 6 can be easily taken out by inserting a tool into the gap 17 'and operating the tool in the front direction.

FIG. 9 is a view drawn in association with FIG. 4, and shows a case where a tip portion of a tool composed of, for example, a driver 20 is inserted into a gap portion 17 ′ formed in the substrate support member 3. Since the gap portion 17 ′ is provided on the back surface of the cutout portion 32 formed in the substrate support member 3, even if the gap portion 17 ′ cannot be viewed by being obstructed by the substrate support member 3, the tool can be easily used. Can be inserted into the gap 17 '.
FIG. 10 shows that the selection substrate 6 can easily move backward (α direction in the figure) by operating the driver 20 in the β direction in the figure. By operating the driver 20 in the β direction in the figure, the driver 20 rotates in the β direction in the figure with the vicinity of the gap 17 ′ hole into which the driver 20 is inserted as a fulcrum, and comes into contact with the side end surface of the selection substrate 6.
