Example 1
Hereinafter, Example 1 of the present invention will be described in detail with reference to FIGS.

  A digital camera 1 as an electronic apparatus embodying the present invention has an appearance as shown in FIG. FIG. 2A is a front perspective view of the digital camera 1, and FIG. 2B is a rear perspective view of the digital camera 1. As shown in FIG. 2, a lens barrel L is disposed on the front surface of the digital camera 1, and a display unit D that displays an image is disposed on the back surface of the digital camera 1.

  FIG. 1 is an exploded perspective view in which the display unit D is disassembled. In FIG. 1, a bezel member 11 covers an outer peripheral region and a side surface of the display surface of the liquid crystal display unit 10.

  FIG. 3 is a view for explaining the characteristics of the bezel member 11. As shown in FIG. 3, an engaging portion 11 a that engages with a hook of the liquid crystal display unit 10 is formed on the side surfaces of the two long sides of the side surface of the bezel member 11, and protrudes outward. An arm portion 11b that is bent in this manner is formed. The arm portion 11b is formed to have a spring property and can be sufficiently elastically deformed.

  Returning to FIG. 1, the bezel member 11 is formed of a conductive material, and is affixed to the outer peripheral region of the display surface of the liquid crystal display unit 10 by a conductive double-sided tape 16. Further, the engaging portion 11 a engages with a hook formed on the side surface of the liquid crystal display unit 10, whereby the bezel member 11 is fixed to the liquid crystal display unit 10.

  In this state, the protective window 5 is bonded to the display surface of the liquid crystal display unit 10 by the transparent resin 12. At this time, the light shielding member 19 is disposed between the protective window 5 and the bezel member 11. The light shielding member 19 is disposed between the protective window 5 and the bezel member 11, thereby preventing the bezel member 11 from being seen from the outside of the protective window 5. The protective window 5 is formed larger than the outer shape of the bezel member 11, and when the protective window 5 is bonded to the liquid crystal display unit 10, the outer peripheral portion of the protective window 5 protrudes greatly from the bezel member 11.

  A holding portion 14 a that holds the protective window 5 is formed on the rear cover 14 that is an exterior member, and an outer peripheral portion of the protective window 5 is attached to the holding portion 14 a by a double-sided tape 15. That is, the integrated liquid crystal display unit 10, bezel member 11, light shielding member 19, and protective window 5 are fixed to the rear cover 14.

  By assembling the liquid crystal display unit 10, the bezel member 11, the light shielding member 19, the protective window 5, and the rear cover 14 in this manner, the liquid crystal display assembly A is obtained.

  Wall portions 17a are formed on the chassis member 17 on which the liquid crystal display assembly A is supported so as to face the four side surfaces of the bezel member 11, respectively. Concave portions 17b into which the arm portions 11b of the bezel member 11 enter are respectively formed on the inner sides of the wall portions 17a facing the side surfaces of the two long sides of the bezel member 11.

  The reinforcing plate 13 that reinforces the chassis member 17 has a notch 13a. The liquid crystal display assembly A is assembled to the chassis member 17 in a state where the reinforcing plate 13 is disposed on the chassis member 17 so that the notch 13a is positioned in the recess 17b. Since one long side of the reinforcing plate 13 is partially cut, when the reinforcing plate 13 is disposed on the chassis member 17, one of the recesses 17b is a portion where the reinforcing plate 13 is not disposed.

  When the liquid crystal display assembly A is assembled to the chassis member 17, the arm portion 11 b of the bezel member 11 comes into contact with the wall portion 17 a or the reinforcing plate 13 of the chassis member 17 and then elastically deforms and enters the recess 17 b of the chassis member 17. By forming the notch 13 a in the reinforcing plate 13, the reinforcing plate 13 does not cover the recess 17 b of the chassis member 17. At this time, the reinforcing plate 13 is disposed in a space formed between the wall portion 17a and the bezel member 11, but between the wall portion 17a and the reinforcing plate 13 or between the reinforcing plate 13 and the bezel member 11. A predetermined clearance is provided between them. In consideration of this clearance, the arm portion 11b of the bezel member 11 is formed to protrude outward. Therefore, when the arm part 11b contacts with the wall part 17a, each arm part 11b gives urging | biasing force with respect to each wall part 17a.

  With such a configuration, the liquid crystal display assembly A is floatingly supported with respect to the chassis member 17. Therefore, it is possible to absorb the misalignment between the liquid crystal display assembly A and the chassis member 17. When the liquid crystal display assembly A is rigidly supported with respect to the chassis member 17, such a displacement cannot be absorbed, and there is a high possibility that the liquid crystal display assembly A is stressed.

  Further, the bezel member 11 is attached to the outer peripheral region of the display surface of the liquid crystal display unit 10 by the double-sided tape 16 having conductivity, whereby the display surface of the liquid crystal display unit 10 and the bezel member 11 are electrically connected. At the same time, the respective bezel members 11 and the chassis member 17 are electrically connected by the respective arm portions 11b coming into contact with the respective wall portions 17a. Further, each arm portion 11b applies a biasing force to each wall portion 17a. Thereby, a sufficient contact pressure is obtained between the arm portion 11b and the wall portion 17a, and the electrical connection between the bezel member 11 and the chassis member 17 is stable.

  Here, since the chassis member 17 is at the ground level potential of the digital camera 1, the display surface of the bezel member 11 and the liquid crystal display unit 10 is also at the ground level potential by such a configuration. In other words, the bezel member 11 of this embodiment can electrically connect the charge charged on the display surface to a portion that is at the ground level potential inside the camera.

  FIG. 4 is a cross-sectional view of a portion where the arm portion 11b of the bezel member 11 and the wall portion 17a of the chassis member 17 are in contact with each other. 4A is an AA cross section in FIG. 4C, and FIG. 4B is a BB cross section in FIG. 4C.

  As shown in FIG. 4A, the arm portion 11b enters the recess portion 17b formed in the wall portion 17a. The liquid crystal display assembly A is positioned by the arm portion 11b entering the concave portion 17b. Since the notch 13a is formed in the reinforcing plate 13, the reinforcing plate 13 is disposed avoiding the contact portion between the arm 11b and the wall 17a.

  As shown in FIG. 4A, one end surface of the reinforcing plate 13 is in contact with the protective window 5, and the other end surface of the reinforcing plate 13 is in contact with the chassis member 17. As a result, even if a strong force is applied to the protective window 5, the force is released to the chassis member 17 and is not transmitted to the liquid crystal display unit 10, so that the liquid crystal display unit 10 can be prevented from being damaged. Further, the rear surface of the holding portion 14 a of the rear cover 14 is in contact with the wall portion 17 a of the chassis member 17. Thereby, even if a strong force is applied to the rear cover 14, the force can be released to the chassis member 17. Further, since the light shielding member 19 is disposed between the protective window 5 and the bezel member 11, the bezel member 11 is not visible from the outside of the protective window 5.

  In the portion illustrated in FIG. 4B, the reinforcing plate 13 is not disposed between the arm portion 11b and the wall portion 17a. In this portion, the wall portion 17a is in direct contact with the protective window 5. As a result, even if a strong force is applied to the protective window 5, the force is transmitted to the chassis member 17, so that a strong force is not transmitted to the liquid crystal display unit 10, and damage to the liquid crystal display unit 10 can be prevented. .

  As described above, according to the first embodiment, since the liquid crystal display assembly A is floatingly supported with respect to the chassis member 17, it is possible to absorb the positional deviation between the liquid crystal display assembly A and the chassis member 17. Therefore, even when the rear cover 14 and the chassis member 17 are assembled after the liquid crystal display unit 10 is assembled to the rear cover 14, the liquid crystal display unit 10 and the chassis member 17 do not interfere with each other, and the liquid crystal display unit 10 is stressed. There is no.

In addition, since the display surface of the liquid crystal display panel and the chassis member can be electrically connected, it is possible to prevent electric charges from being charged on the display surface of the liquid crystal display panel.
(Example 2)
In the first embodiment, the case where the protective window 5 is formed larger than the outer shape of the bezel member 11 has been described. Example 2 demonstrates the case where protective window 5 'is formed smaller than the external shape of the bezel member 11, referring FIGS. In addition, the same code | symbol is attached | subjected about the same member and the overlapping description is abbreviate | omitted.

  FIG. 5 shows an exploded perspective view of the second embodiment. In the second embodiment, the bezel member 11 is fixed to the liquid crystal display unit 10 as in the first embodiment. Thereafter, the protective window 5 ′ is bonded to the display surface of the liquid crystal display unit 10 by the transparent resin 12. Further, a buffer member 18 is attached to the surface of the bezel member 11. Thus, the liquid crystal display assembly B is obtained by assembling the liquid crystal display unit 10, the bezel member 11, the protective window 5 ′, and the buffer member 18.

  The liquid crystal display assembly B is assembled to the chassis member 17. The reinforcing plate 13 is disposed in a space formed between the wall portion 17 a and the bezel member 11 after the liquid crystal display assembly B is assembled to the chassis member 17. At this time, the cutout portion 13a of the reinforcing plate 13 avoids the contact portion between the arm portion 11b and the wall portion 17a. A reinforcing plate 13 is arranged. Then, the rear cover 14 ′ that is an exterior member is fixed to the chassis member 17. At this time, the liquid crystal display assembly B is moved and positioned with respect to the chassis member 17 by the contact between the outer peripheral end surface of the protective window 5 ′ and the rear cover 14 ′ opening end surface. Also in this case, since the liquid crystal display assembly B is floatingly supported with respect to the chassis member 17, even if the liquid crystal display assembly B moves relative to the chassis member 17, the liquid crystal display panel is not stressed. . Further, even after the liquid crystal display assembly B is positioned with respect to the chassis member 17, the arm portion 11b is in contact with the wall portion 17a. Therefore, the display surface of the liquid crystal display unit 10 and the chassis member 17 are electrically connected by the bezel member 11.

  6A is an A′-A ′ cross section in FIG. 6C, and FIG. 6B is a B′-B ′ cross section in FIG. 6C.

  As shown in FIG. 6 (a), the arm portion 11b enters a recess 17b formed in the wall portion 17a, and the reinforcing plate 13 ′ has a notch portion 13a formed between the arm portion 11b and the wall portion. The point which does not prevent the contact with 17a is the same as that of Example 1. However, one end face of the reinforcing plate 13 'abuts on the rear cover 14'. Then, the wall portion 17a of the chassis member 17 contacts the rear cover 14 '.

  A buffer member 18 is disposed between the rear cover 14 ′ and the bezel member 11. This prevents deformation in the vicinity of the opening end of the rear cover 14 '.

  6B is the same as that of the first embodiment in that the reinforcing plate 13 is not between the arm portion 11b and the wall portion 17a. Also in this portion, a buffer member 18 is disposed between the rear cover 14 'and the bezel member 11 to prevent deformation near the opening end of the rear cover 14'.

  According to the second embodiment, since the liquid crystal display assembly B is floatingly supported with respect to the chassis member 17, the liquid crystal display unit 10 and the chassis member 17 do not interfere with each other even when the above-described configuration is adopted. The unit 10 is not stressed. It is also possible to prevent electric charges from being charged on the display surface of the liquid crystal display panel.

  The embodiment of the present invention has been specifically described above. However, the present invention is not limited to the matters described as the above-described embodiments, and can be appropriately changed without departing from the technical idea of the present invention.
