  An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is an exploded perspective view of a cover and a main body constituting a collective entrance machine which is an example of the electronic apparatus of the present invention, and FIG. 2 is a rear view of the main body.

  In FIG. 1, reference numeral 1 denotes a collective entrance machine which is an example of the electronic apparatus of the present invention, and includes a cover 2 and a main body 3. A numeric keypad main body 5 is assembled to the main body 3 adjacent to the speaker box 4. The cover 2 is provided separately from the numeric keypad main body 5 and has a key top portion 6 attached to the cover 2 from the back side of the cover 2. Further, as shown in detail in the rear view of FIG. 2, the main body 3 is provided with a substrate 6 at the center, and a camera housing portion 7 provided above the substrate 6. A microphone 8 is attached to a position adjacent to the camera housing portion 7 with its sound collection portion facing a sound collection hole 8 a formed in the main body 3. The microphone 8 and the board 6 are connected by a harness 10, the microphone side connection end 10 a (electronic member side connection end) of the harness 10 is connected to the microphone 8, and the board side connection end 10 c of the harness 10 is the front side of the board 6. Is connected to the substrate 6 through a plug-in connector 9 from the side mounted on the board.

  As described above, in this embodiment, a microphone or a speaker, which is an electronic member, is connected to the board via a harness with a connector. The advantage of using this harness is that there is no need to attach the microphone directly to the board, so the microphone can be placed in the camera compartment at the corner of the main unit, in the embodiment, at the upper right side of the main unit (when viewed from the front). it can. By positioning the microphone on the outside of the substrate in this manner, the distance between the microphone and the speaker can be made larger than the diagonal line of the substrate, which is the maximum length of the substrate, and an arrangement structure advantageous for preventing howling can be obtained. On the other hand, when the distance between the microphone and the speaker is increased without using the harness, the board itself must be enlarged, and the mounting position on the board is also limited.

  The camera storage unit 7 is surrounded by a vertical wall so that water does not enter from the upper part of the main body. By providing the microphone 8 in the camera housing portion 7 together, the waterproof effect of the microphone 8 can be enhanced. A groove for inserting the harness 10 is provided in a vertical wall located below the camera storage unit 7 and located below the microphone 8.

Furthermore, the harness insertion groove 11 is tapered in the pushing direction, and the harness 10 can be easily held in the harness insertion groove 11 by pushing the harness 10 into the harness insertion groove 11. ing.

  The microphone 8 and the connector 9 are both located above the harness insertion groove 11, and the harness 10 passes through the harness insertion groove 11, so that the harness insertion groove is directed from the outside of the vertical side wall 12 toward the board 6. 11, a bent portion 10 b that is bent obliquely upward is formed to be bent in a U shape, and is folded upward from the downward direction, that is, in a U shape via the bent portion 10 b. Therefore, if the harness 10 has the connection end 10a on the microphone 8 side as a base end, the harness 10 descends from the microphone connection end 10a and passes through the harness insertion portion 11 from the outside of the side wall 12 so that the bent portion 10b is It is formed, folded from the downward direction to the upward direction through the bent portion 10b, turned from the lowered position to the raised position, and reaches the connection end portion 10c on the connector 9 side.

  Accordingly, for example, even if water droplets are generated in the harness 10 due to condensation or the like and the water droplets travel through the harness 10, a bent portion 10b is formed in the middle of the harness 10, and the harness 10 is interposed via the bent portion 10b. Is folded upward from below, water droplets do not propagate beyond the bent portion 10b, and the connector 9 is located above the harness insertion groove 11, so it does not travel to the connector 9. That is, it is possible to prevent water droplets from entering the substrate 6, and even if the microphone 8 is not disposed below the substrate 6 but disposed above the substrate 6, a rainproof / drip-proof structure can be obtained. Therefore, in other words, the degree of freedom in design can be expanded as compared with the conventional example while obtaining a rainproof / dripproof structure. Further, since the bent portion 10b is provided on the side of the substrate, the length of the harness does not become longer than necessary.

  In the present embodiment, the microphone 8 is disposed above the substrate 6, and a speaker (not shown) in the speaker box 4 is disposed obliquely below the microphone 8, that is, in the speaker placement portion 4a of FIG. As a result, the microphone 8 and the speaker in the speaker box 4 can be spaced apart enough to prevent howling while obtaining a rainproof / drip-proof structure.

  In the present embodiment, the bent portion forming means for forming the bent portion in the harness is configured by the harness insertion groove portion formed in the longitudinal side wall. For example, a cylindrical boss or column is provided on the outer side of the side wall. The folded portion may be formed in the harness by folding the harness so that the harness is hooked on the boss.
