Protrudes into the shield member 41 and contacts the camera 40, so that the camera 40 is directly positioned by the holder 36.

  Thereby, the camera 40 can be reliably shielded and positioned. Here, since the convex portion for positioning penetrates the opening and directly contacts the camera 40, positioning can be performed with higher accuracy than positioning through the shield member 41.

  In the above-described embodiment, the convex portion is positioned by contacting the camera 40, but is not limited thereto. Since each member has a variation in size, some play may be provided between the convex portion and the camera 40 in order to absorb the variation. That is, the camera 40 and the convex portion are close enough to prevent the camera 40 from coming off the desired position by contacting the convex portion when the camera 40 is likely to be unacceptably removed from the desired position during assembly. It doesn't have to be in constant contact.

  Moreover, since the convex part 38 and the opening 44 are provided in the plane diagonal position of the camera attachment opening part 37, the camera 40 can be positioned reliably.

Further, since the side walls 43 adjacent to each other in the shield member 41 are divided by the slits 431, the side walls 43 can be bent by the gaps of the slits 431. Accordingly, the shield member 41 can be easily fitted into the camera mounting opening 37.
Furthermore, by making the openings provided at the positions corresponding to the corners of the camera 40 continuous with the slits, it becomes easy to form the shield member 41 by bending a single metal plate. That is, since the portion where the distance between the side walls 43 is the smallest (when there is no opening) is cut out as an opening, the side walls 43 are prevented from interfering and distorting when bent. Can do.

  Furthermore, in the shield member 41, since the notch portions 461 are provided so that the plurality of flange portions 46 arranged outside the camera attachment opening portion 37 do not interfere with each other, it is possible to prevent biting between the flange portions 46.

Note that the electronic apparatus of the present invention is not limited to the above-described embodiment, and appropriate modifications and improvements can be made.
For example, in the above-described embodiment, the case where the slit 431 is provided between the adjacent side walls 43 of the shield member 41 to divide the shield member 41 is illustrated. However, in the present invention, as shown in FIG. It is also applicable to

  In the above-described embodiment, the convex portions 38, 381, 382 are provided at the three corners and the central portion of the inner surface 371 as the convex portions 38, 381, 382 provided in the camera mounting opening 37 of the holder 36. As shown in FIG. 8, a pair of convex portions 38 can be provided at each of the four corners.

In the above-described embodiment, the camera is described as an example of the electronic component, but the present invention is not limited to this. Other electronic components that require shielding may also be used.
In the above-described embodiment, a substantially rectangular electronic component such as the camera 40 has been described as an example. However, the present invention is not limited to this. For example, the cross section may be substantially triangular or other polygonal electronic component.

  In the above-described embodiment, the description has been made using the mobile terminal as an example of the electronic device, but the present invention is not limited to this. Any device may be used as long as the electronic device includes an electronic component that needs to be provided with a shield. For example, application to a built-in camera such as a stationary PC is conceivable.

  In the above-described embodiment, the positioning by the convex portion is performed at the end of the camera 40 in the direction of pushing into the concave portion of the holder. However, the present invention is not limited to this. For example, positioning may be performed near the center in the thickness direction, or positioning may be performed at the bottom in the direction of pushing into the concave portion of the camera 40. That is, as long as an opening is provided in the shield and a convex portion that positions the camera 40 through the opening is provided, the position of the opening and the convex portion is not limited.
