Next, a method for manufacturing (attaching) the power switch unit 10 will be described.
FIG. 15 is a flowchart of a method for manufacturing (attaching) the power switch unit 10. In addition, the main-body part 3 before attaching the display part 2 and the power switch unit 10 shall already be manufactured.

  The light shielding member 11 and the light emitting member 12 before the light shielding film is formed are formed, and the light shielding film is formed on the light shielding member 11 by sputtering (ST1501).

  The base material of the light shielding member 11 is made of, for example, a material such as ABS resin, which is a material on which a light shielding film is formed by sputtering, and the light emitting member 12 is a milky white resin having translucency in which the light shielding film is not formed by sputtering. Materials are used. The light shielding member 11 and the light emitting member 12 may be manufactured in advance and then combined.

  The substrate 16 connected to the flexible substrate from the inside of the main body 3 is inserted into the substrate holding portion 53 of the support member 15, and the light shielding member 11, the light emitting member 12, the surrounding member 13, the button 14, and the support member 15 shown in FIG. 7 are combined to produce the power switch unit 10 shown in FIG. 5 (ST1502). At this time, the positioning unit 42 positions the light emitting member 12 and the light shielding member 11 with respect to the rotation direction (circumferential direction) so as to avoid the protruding legs 22 illustrated in FIG. 6 being located on the front side of the electronic device 1. .

  The positioning unit 41 of the power switch unit 10 shown in FIG. 4 is fixed to the positioning unit 71 of the main body side housing 7 as shown in FIG. 1 (ST1503). The positioning unit 71 is a wall provided substantially parallel to the plane of the keyboard unit 8 (XY plane in FIG. 1). The positioning portion 41 and the positioning portion 71 of the main body side housing 7 are planarly overlapped and screwed.

Next, the optical path of the light emitted from the light emitting element 61 of the power switch unit 10 will be described.
FIG. 16 is an optical path diagram of light emitted from the light emitting element 61 of the power switch unit 10.
For example, light emitted from the light emitting element 61 enters the diffusion sheet 50. The light incident on the diffusion sheet 50 is scattered by the diffusion sheet 50, passes through the transparent button 14, and is emitted from the pressing surface 43 to the outside of the button 14. The light scattered by the diffusion sheet 50 is uniformly scattered around the axis of the alternate long and short dash line shown in FIG. As a result, the scattered light passes, for example, from the vicinity of the center of the base portion 46 to the vicinity of the corner portion 49, enters the light emitting member 12 from the inclined surface 37 of the light emitting member 12, etc. The light is transmitted through the part 31 and spreads out uniformly in a ring shape outside the light emitting part 31.

  As described above, according to the present embodiment, the ring-shaped light shielding portion 21 surrounds the outer peripheral surface 44 of the button 14, so that the design is not impaired. Light emitted from the light emitting element 61 is incident on the diffusion sheet 50 provided on the bottom surface of the base 46 of the button 14 and scattered, passes through the button 14, exits from the pressing surface 43, and the pressing surface 43 emits light. Further, the light emitted from the light emitting element 61 enters and scatters from the diffusion sheet 50 provided on the bottom surface of the base portion 46 of the button 14, passes through the button 14 and the ring-shaped light-emitting portion 31, and the ring-shaped light-emitting portion. The light is scattered within 31 and emitted from the outer peripheral surface S of the light emitting portion 31, and the outer peripheral surface S emits light. The user operating the electronic device 1 from the front side, not only from one side surface (Y direction side in FIG. 16), includes the light emitting element 61 by light emission from the outer peripheral surface S of the ring-shaped light emitting unit 31. Can be confirmed. In addition, since the ring-shaped light emitting portion 31 surrounds the outer peripheral surface 44 near the base portion 46 of the button 14, the ring-shaped light emitting portion 31 has a structure of an axis (an axis parallel to the Y direction indicated by a one-dot chain line in FIG. 16). Therefore, the ring-shaped light emitting portion 31 can emit light uniformly from the outer peripheral surface S thereof.

  The surrounding member 13 of the electronic device 1 rotates the light emitting member 12 and the light shielding member 11 in the rotation direction (circumferential direction) so as to avoid the protruding legs 22 being positioned on the front side (X direction side shown in FIG. 6) of the electronic device 1. ) With respect to the positioning portion 42. Therefore, by avoiding the protruding leg 22 from being positioned on the front side of the electronic device 1, the light emitting state of the button 14 is not impaired by the protruding leg 22 for the user operating the electronic device 1 from the front.

  As shown in FIG. 7, the light emitting member 12 includes a recess 36 that surrounds the outer peripheral surface 48 of the base 46 of the button 14 and has an inclined surface 37 at a position facing the corner 49 of the outer edge of the base 46 of the button 14. By providing the light emitting member 12 with the inclined surface 37, light emitted from the vicinity of the corner portion 49 of the outer edge of the base portion 46 of the button 14 is less reflected when entering the light emitting member 12, and emits light from the light emitting member 12. The amount of light can be increased.

  As shown in FIG. 3, the ring-shaped light emitting unit 31 of the power switch unit 10 is in a state where the electronic device 1 is always exposed to the outside regardless of the open / closed state. For this reason, even if the display unit 2 is closed with the power on, the light from the ring-shaped light emitting unit 31 can be visually recognized without looking at the button 14 of the electronic device 1.

  For example, the electronic device 1 causes the light emitting element 61 to light red (orange) light when the power is on, or causes the light emitting element 62 to blink green light when in the power saving standby state. These states can be confirmed by the user.

  The ring-shaped light emitting portion 31 is made of a translucent resin material (Clear PC clear polycarbonate or the like) to which the light shielding film does not adhere by sputtering, and the base material of the light shielding member 11 is made of the base material to which the light shielding film adheres by sputtering. Become. For this reason, for example, the light emitting part 31 and the light shielding part 21 can be formed in the same sputtering process. Therefore, the manufacturing process can be shortened and the manufacturing cost can be reduced.

By arranging the power switch unit 10 at the hinge connecting portion that was a dead space, there is a degree of freedom in the arrangement of the parts of the main body 3 and the display unit 2, and the main body by devising the arrangement of these parts. 3 and the thinning of the display unit 2 are promoted. Further, the power switch unit 10 is provided at a position away from the keyboard unit 8 and is configured to surround the button 14 and to project the outer periphery of the button 14. Therefore, it is possible to prevent the power from being accidentally turned off during use.
