Next, the cover holding method according to this embodiment will be described. The cover holding method is a method in which the cover 3 that covers the first region 11 in the surface of the main body 2 is pressed by the pressing plate 6. In the cover holding method, the presser plate 6 is first attached to the main body 2.

When the presser plate 6 is attached to the main body 2, first, as shown in FIGS. 9A, 9B and 10, the rotary shaft portion 4 is inserted into the insertion hole 43 of the plate main body 41, and then the plate main body 41 is attached to the main body 2. It arrange | positions so that it may surface-contact with the 2nd area | region 12 of this. When the rotation shaft portion 4 is inserted through the insertion hole 43 of the plate body 41, the tip portion of the first leaf spring portion 47 of the spring portion 42 is pushed by the rotation shaft portion 4, and the plate thickness direction of the plate body 41 is increased. , The plate body 41 is elastically bent and deformed away from the second region 12 of the body 2. In this state, the tip of the first leaf spring portion 47 is in contact with the outer peripheral surface of the rotating shaft portion 4. Further, the tip of the second leaf spring portion 48 of the spring portion 42 is positioned higher than the tip 32 of the rotating shaft portion 4 in the protruding direction of the rotating shaft portion 4.
When the rotary shaft portion 4 is inserted through the insertion hole 43 of the plate body 41, the entire guide 44 of the insertion hole 43 contacts the outer peripheral surface of the rotary shaft portion 4 (see FIG. 6). Further, the spring portion 42 is positioned so as to sandwich the rotating shaft portion 4 in the radial direction. For this reason, the position of the presser plate 6 with respect to the rotating shaft portion 4 is not shifted by the elastic force of the first plate spring portion 47 that is bent and deformed.

Next, as shown in FIG. 11, the spring portion 42 of the presser plate 6 is sandwiched between the plate body 41 and the flat washer 35 (flange portion 5) of the screw 7 with washer. Specifically, the screw 7 with a washer is engaged with the female screw 31 of the rotating shaft portion 4 from the tip 32 side of the rotating shaft portion 4, and the flat washer 35 (flange portion 5) is brought close to the second region 12 of the main body 2. Thereby, the spring part 42 is inserted | pinched between the plate main body 41 and the flat washer 35 (flange part 5).

In a state where the presser plate 6 is disposed at the first rotation position P1, the presser part 46 of the plate main body 41 is positioned on the cover 3 (on the first region 11 of the main body 2). For this reason, the plate main body 41 can press the cover 3 toward the surface of the main body 2 by the elastic force of the spring portion 42.
On the other hand, when the cover 3 is not pressed by the presser plate 6 as shown in FIG. 3, the presser plate 6 may be rotated and disposed at the second rotation position P2. In this state, the entire plate main body 41 (particularly the pressing portion 46) is located on the second region 12 of the main body 2. In this state, the cover 3 can be attached to and detached from the main body 2.
Thus, the cover holding method of the present embodiment is completed.

As described above, according to the cover holding structure 1 and the cover holding method of the present embodiment, between the peripheral edge portion of the insertion hole 43 of the plate body 41 and the flat washer 35 (flange portion 5) of the screw 7 with the washer. The plate body 41 of the pressing plate 6 can hold the cover 3 toward the surface of the main body 2 by the elastic force of the sandwiched spring portion 42, and the cover 3 can be held on the main body 2. For this reason, it is not necessary to form a convex part in the pressing plate 6. As a result, it is possible to suppress or prevent the main body 2 and the cover 3 from being damaged or deformed even if the presser plate 6 is rotated.

In the present embodiment, the spring portion 42 is configured to press the plate main body 41 against the second region 12 of the main body 2. For this reason, it is possible to prevent a change in the shape of the spring portion 42 regardless of the rotational position of the presser plate 6. Moreover, it can suppress that a change (for example, bending deformation) arises in the shape of the plate main body 41 according to the rotation position of the presser plate 6. FIG. In particular, in the cover holding structure 1 of the present embodiment, the surface of the main body 2 (second region 12) and the surface 21 of the cover 3 form the same plane with the cover 3 covering the first region 11 of the main body 2. To do. For this reason, it is possible to prevent the shape of the plate body 41 from changing according to the rotational position of the presser plate 6. Thereby, the plastic deformation of the plate main body 41 and the spring part 42 can be suppressed or prevented. Therefore, the cover 3 can be satisfactorily held with respect to the main body 2 even if the presser plate 6 is repeatedly rotated between the first rotation position P1 and the second rotation position P2.

In the present embodiment, the spring portion 42 is configured to press the plate main body 41 against the second region 12 of the main body 2. For this reason, compared with the case where the plate main body 41 is pinched | interposed between the 2nd area | region 12 of the main body 2, and the plain washer 35 of the screw 7 with a washer, the number of components of the cover holding structure 1 can be reduced. Hereinafter, this point will be specifically described.

When the plate main body 41 is sandwiched between the second region 12 of the main body 2 and the flat washer 35 of the screw 7 with a washer, the frictional resistance between the main body 2 and the presser plate 6 increases as the presser plate 6 rotates. . For this reason, it is necessary to sandwich a member having high slidability between the main body 2 and the presser plate 6 to reduce the frictional resistance between the main body 2 and the presser plate 6.
On the other hand, in the configuration in which the plate body 41 is pressed against the second region 12 of the main body 2 by the elastic force of the spring portion 42 as in the present embodiment, the rotation of the presser plate 6 is adjusted by adjusting the elastic force of the spring portion 42. The frictional resistance between the main body 2 and the presser plate 6 accompanying the movement can be kept small. This eliminates the need for a highly slidable member between the main body 2 and the presser plate 6. That is, the number of components of the cover holding structure 1 can be reduced.

Further, according to the present embodiment, it is not necessary to form a convex portion on the presser plate 6 as described above. For this reason, the cover holding structure 1 can be employed in a product only by adjusting the elastic force of the spring portion 42 so that the cover 3 can be pressed with an appropriate force. Thereby, it is possible to reduce the development time and cost required until the cover holding structure 1 is adopted in a product.

In the cover holding structure 1 of the present embodiment, the spring portion 42 that presses the plate main body 41 against the second region 12 of the main body 2 is sandwiched between the plate main body 41 and the flat washer 35 (flange portion 5). . Therefore, it is possible to easily adjust the elastic force of the spring portion 42 that presses the plate body 41 against the body 2. For example, the elastic force of the spring part 42 can be adjusted only by changing the distance between the plate body 41 and the flat washer 35 (flange part 5). Further, the plate thickness and material of the holding plate 6, the number of the spring portions 42, the length and width dimensions of the first leaf spring portion 47 and the second leaf spring portion 48, the second leaf spring portion with respect to the first leaf spring portion 47. The elastic force of the spring portion 42 can be adjusted only by changing at least one of the 48 folding angles. Moreover, the elastic force of the spring part 42 can be adjusted only by changing the outer diameter and height dimension of the rotating shaft part 4.

Further, in the cover holding structure 1 of the present embodiment, a spring portion 42 for pressing the plate main body 41 against the second region 12 of the main body 2 is formed integrally with the plate main body 41. For this reason, compared with the case where the spring part 42 is formed separately from the plate main body 41, the number of components of the cover holding structure 1 can be further reduced.

Further, in the cover holding structure 1 of the present embodiment, the spring part 42 formed integrally with the plate body 41 includes a first plate spring part 47 formed integrally with the plate body 41 and a first plate spring part 47. A second leaf spring portion 48 formed integrally with the tip. For this reason, the presser plate 6 in which the spring portion 42 is formed integrally with the plate main body 41 can be easily manufactured simply by subjecting a single plate material to processing such as cutting, pressing, and bending.

Further, in the cover holding structure 1 of this embodiment, a plurality of spring portions 42 formed integrally with the plate body 41 are arranged at equal intervals in the circumferential direction of the insertion hole 43. For this reason, the plate body 41 can be evenly pressed against the second region 12 of the body 2 in the circumferential direction of the insertion hole 43 by the elastic force of the plurality of spring portions 42. Thereby, the cover 3 can be stably held on the surface of the main body 2.
In addition, since the cover holding structure 1 includes the plurality of spring portions 42, even if the elastic force of each spring portion 42 is small, the elastic force (strength) of the spring portion 42 that presses the plate main body 41 against the surface of the main body 2. Can be secured.

Further, according to the cover holding structure 1 of the present embodiment, the rigidity of the plate body 41 is increased by the pair of extension plate portions 52 integrally formed at both ends in the width direction of the plate body 41 formed in a band plate shape. It is possible to effectively suppress bending and deformation so that the plate body 41 is warped. For example, even when the cover 3 is pressed against the presser plate 6 in a state where the presser plate 6 is arranged at the first rotation position P1 that presses the cover 3, the product including the cover 3 holding structure is pressed against the presser plate 6, It is possible to suppress the plate body 41 from being bent and deformed. Further, if the surface 21 of the cover 3 is positioned higher than the second region 12 of the main body 2, the pressing portion 46 of the plate main body 41 in a state where the pressing plate 6 is disposed at the first rotation position P <b> 1 where the cover 3 is pressed. May be pushed up by the cover 3. Even in this case, the plate body 41 can be prevented from being bent and deformed. The cover 3 can be favorably held with respect to the main body 2 by suppressing the bending deformation of the plate main body 41.
Further, since the presser plate 6 includes the extension plate portion 52, the presser plate 6 can be easily grasped with the fingers of the operator. That is, the operator can easily operate the presser plate 6.

Further, according to the cover holding structure 1 of the present embodiment, the spring portion 42 is provided in the peripheral portion of the insertion hole 43 in the plate body 41. For this reason, even if the rigidity of the plate body 41 is reinforced by the pair of extension plate portions 52, this reinforcement does not affect the elastic force of the spring portion 42. That is, both the rigidity of the plate body 41 and the elastic force of the spring portion 42 can be ensured.

Further, in the cover holding structure 1 of the present embodiment, the distal end portion of the extension plate portion 52 is folded back inside the plate body 41 in the width direction of the plate body 41. For this reason, the roundness 57 (refer FIG. 8) can be given to the substantial front-end | tip of the extension plate part 52. FIG. Moreover, in the cover holding structure 1 of this embodiment, the corner | angular part 56 (refer FIG. 7) of the both ends of the extension board part 52 in the longitudinal direction of the board main body 41 is scraped off by C surface processing. Thereby, when an operator's finger touches the extension board part 52, it can suppress that it is damaged.

As described above, one embodiment of the display device and the electronic component protecting method according to the present invention has been described. However, the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the scope of the present invention. .

In the present invention, the flange portion 5 may be, for example, a screw head meshing with the female screw 31 of the rotating shaft portion 4, or a plain washer sandwiched between the screw head and the tip 32 of the rotating shaft portion 4. It may be. Moreover, the flange part 5 may be fixed to the front-end | tip 32 of the rotating shaft part 4 so that attachment or detachment is impossible, for example as shown in FIG. 12, and may be integrally formed in the front-end | tip 32 of the rotating shaft part 4, for example.

FIG. 12 is an enlarged cross-sectional view showing a cover holding structure according to another embodiment.
In the present invention, the spring portion 42 may be formed separately from the plate main body 41 as shown in FIG. 12, for example, and may be fixed to the peripheral portion of the insertion hole 43 in the plate main body 41.
