Next, the penetrating part 22 and the restricting part 30 will be described in detail. FIG. 3 is a perspective view showing the first operation button 20a and the first restriction component 30a according to this embodiment.

The penetrating portion 22 has a mounting groove 24 and a connecting groove 26 . The mounting groove 24 is a groove provided closer to the first operating portion 21a than the connecting groove 26 is. The inner diameter of the mounting groove 24 is formed to have substantially the same size as the inner diameter of the water stop ring 17 . The water stop ring 17 is attached to the attachment groove 24 .

The restriction component 30 has curved first arm portions 36 and second arm portions 37 extending from both ends of the bending portion 33 in the Y direction toward substantially the center in the Y direction. Between the first arm portion 36 and the second arm portion 37, a gap slightly narrower than the portion of the through portion 22 where the connecting groove 26 is provided is formed. Further, the tips of the first arm portion 36 and the second arm portion 37 widen toward the outside. In other words, the distal ends of the first arm portion 36 and the second arm portion 37 allow the penetrating portion 22 to be easily inserted into the gap between the first arm portion 36 and the second arm portion 37 .

Further, the restricting component 30 has a first projecting portion 34 and a second projecting portion 35 on both sides of the gap 38 at substantially the center of the bent portion 33 . The first projecting portion 34 and the second projecting portion 35 are plate-shaped projections extending in the -Z direction.

The penetrating portion 22 is connected to the restricting component 30 by fitting the first projecting portion 34 and the second projecting portion 35 into the connecting groove 26 . In addition, since the gap between the first arm portion 36 and the second arm portion 37 narrows toward the center, the connection groove 26 is prevented from being removed from the gap 38 .

Next, the elastic component 40 will be explained. FIG. 4 is a perspective view showing the elastic component 40 according to this embodiment.

The elastic component 40 extends between the mounting portion 44 to which the restricting component 30 is mounted and the mounting surface 511 of the side wall 13 and the switch board 15 while being connected to the mounting portion 44 and extending substantially in the X direction intersecting the mounting surface 511 .

Thereby, the first absorption portion 42 and the second absorption portion 43 absorb the dimensional tolerance in the Y direction. Also, the first absorbing portion 42 and the second absorbing portion 43 absorb pressure in the Y direction.

Further, the first flat portion 41a is provided with a first mounting portion 44a and incorporates the first limiting component 30a.

In this way, since there is point contact rather than surface contact, the first protrusion 48 and the second protrusion 49 reduce friction due to contact between the first inner surface 121 of the panel cover 12 and the elastic component 40. can do.

FIG. 5 is a cross-sectional view showing a cross section of the electronic device 10 according to this embodiment. A portion of the through portion 22 passes through the through hole 16 and is arranged inside the electronic device 10 relative to the side wall 13 . When the user presses the first operation portion 21a or the second operation portion 21b in the +X direction, force is applied to the penetrating portion 22 in the +X direction. Since the restriction component 30 is coupled to the through portion 22, it is pushed in the +X direction by the through portion 22 and pushes the elastic component 40 in the +X direction. After contacting the mounting surface 511 , the first support plate 46 and the second support plate 47 of the elastic component 40 are compressed in the X direction between the moving limiting component 30 and the mounting surface 511 . Furthermore, when the restriction component 30 moves in the +X direction, the first support plate 46 and the second support plate 47 buckle. As a result, the penetrating portion 22 presses the switch 53 provided on the switch substrate 15 .

When the user finishes pressing the first operation button 20a or the second operation button 20b, the switch 53 pushes the penetrating portion 22 in the -X direction. Also, since the first support plate 46 and the second support plate 47 are elastic bodies, they move the penetrating portion 22 in the -X direction by their restoring force. As a result, the elastic component 40 moves the first operation button 20a or the second operation button 20b to the position before being pressed by the user.

A water stop ring 17 is attached to the attachment groove 24 of the through portion 22 . Water stop ring 17 closes the gap between penetrating portion 22 and the inner surface of through hole 16 by being sandwiched between penetrating portion 22 and the inner surface of through hole 16 . As a result, the water stop ring 17 prevents water from entering inside the side wall 13 of the electronic device 10 through the through hole 16 .

FIG. 6 is a cross-sectional view showing a cross section of the electronic device 10 according to this embodiment. The antenna portion 70 of the side wall 13 is covered with the inner insulating portion 18 on the inner side of the side wall 13 and parallel to the Z direction. The internal insulating portion 18 is made of an insulating material such as synthetic resin.

Further, the housing 11 is provided with a bottom insulating portion 13 c so as to surround the antenna portion 70 . The bottom insulating portion 13c is made of an insulating material such as synthetic resin. Thus, the antenna section 70 is surrounded by the first side wall insulating section 13a, the second side wall insulating section 13b, the inner insulating section 18, and the bottom insulating section 13c.

Also, the elastic component 40 is arranged inside the panel cover 12 . Here, the elastic component 40 is provided with a first protrusion 48 on the first plane portion 41a and a second protrusion 49 on the second plane portion 41b. When the user touches the panel cover 12 , the panel cover 12 contacts the first protrusion 48 or the second protrusion 49 . Therefore, the first protrusion 48 and the second protrusion 49 can reduce friction generated by contact between the panel cover 12 and the elastic component 40 .

The electronic device 10 can reduce the friction generated in the elastic component 40 as compared with the case where the flat surface 411a of the elastic component 40 contacts the second inner surface 141, and consequently the first operation button 20a or the second operation button 20b. You can smooth out your movement. For example, when the panel cover 12 is pushed down due to contact by a user, the elastic component 40 is compressed between the first inner surface 121 and the second inner surface 141 . In this case, the first projecting portion 48 or the second projecting portion 49 is more likely to be elastically deformed than the other portions, and the deformation of the other portions can be alleviated. As a result, the electronic device 10 can prevent the operation feeling of the first operation button 20a or the second operation button 20b from being affected when the panel cover 12 is pushed down.

That is, the connecting portion 910 is connected to the penetrating portion 22 inside the housing 11 . The first support plate 46 and the second support plate 47 are connected to the joint portion 910 and positioned between the joint portion 910 and the switch substrate 15 .

The holding part 900 has a first position where the penetrating part 22 pushes the switch 53 and a contact part 910 with the side wall 13 so that the first operation button 20a or the second operation button 20b moves in the +X direction with respect to the side wall 13. holds the first operating button 20a or the second operating button 20b movably between a second position that restricts movement in the opposite -X direction. When the first support plate 46 and the second support plate 47 are elastically deformed between the switch board 15 and the coupling portion 910, the holding component 900 is held in the first position by the restoring force of the elastic deformation. in the -X direction.

In the electronic device 10 according to the first embodiment described above, the first operation button 20a or the second operation button 20b includes a first operation section 21a or a second operation section 21b positioned outside the housing 11, and a through portion 22 extending in the +X direction from the first operating portion 21a or the second operating portion 21b. The penetrating portion 22 passes through a through hole 16 that is provided in the side wall 13 and communicates the inside and the outside of the housing 11 . The first operation button 20a or the second operation button 20b is movable with respect to the housing 11 in the +X direction and the -X direction opposite to the +X direction.

The restricting component 30 is coupled with the through portion 22 inside the housing 11, and restricts the movement of the first operating button 20a or the second operating button 20b in the -X direction when coming into contact with the side wall 13. FIG. The elastic component 40 includes a mounting portion 44 to which the restricting component 30 is mounted, a first support plate 46 connected to the mounting portion 44 and extending between the side wall 13 and the mounting surface 511 in a direction intersecting the mounting surface 511; and a second support plate 47 . When the penetrating part 22 is in the position to press the switch 53, the elastic part 40 abuts against the mounting surface 511 and elastically deforms to push the limiting part 30 in the -X direction with the restoring force of the elastic deformation.

As a result, after the user presses the first operation button 20a or the second operation button 20b in the +X direction and the penetrating part 22 presses the switch 53, the elastic part 40 is connected to the restricting part 30 by the restoring force. Part 22 can be returned to its original position. In the electronic device 10, the elastic component 40 is elastically deformed when the penetrating portion 22 presses the switch 53. Therefore, when the user presses the first operation button 20a or the second operation button 20b, for example, the first operation button 20a or the second operation button 20b is pressed. Collision between hard parts such as the two-operation button 20b and the housing 11 can be mitigated, and noise generated by the collision can be suppressed. Further, the penetrating portion 22 extends from the first operating portion 21a or the second operating portion 21b operated by the user, and the penetrating portion 22 directly presses the switch 53, so that the electronic device 10 can operate the first operating button 20a and the second operating portion 21b. It is possible to improve the operational feeling of the operation button 20b.
