(Embodiment)
The electronic device according to the embodiment is the mobile phone 1 shown in FIG. The mobile phone 1 is a so-called foldable mobile phone, and is capable of rotating the first casing 100, the second casing 200, the first casing 100, and the second casing 200. And a hinge device 300 to be coupled. The first housing 100 includes a display unit 110 configured from an LCD (Liquid Crystal Display). The second housing 200 includes an operation unit 210 configured with a plurality of keys. The hinge device 300 is a so-called biaxial hinge, and connects the first housing 100 and the second housing 200 so as to be rotatable around the X axis, and also connects the first housing 100 to the X axis. It is supported so as to be rotatable around a Y axis perpendicular to the axis. FIG. 1 shows a state in which the mobile phone 1 is opened so that the display unit 110 and the operation unit 210 face each other in the same direction. FIG. 2 shows a state in which the mobile phone 1 is closed so that the display unit 110 and the operation unit 210 face each other. As shown in FIG. 2, the first casing 100 is provided with an illumination device 5 that notifies the incoming call of the mobile phone 1 by light.

  Next, the configuration of the first housing 100 including the illumination device 5 will be described in detail with reference to FIGS.

  As shown in FIG. 3, the first casing 100 includes a first case 101 and a second case 102 that are combined in the vertical direction. The first housing 100 accommodates a first substrate 120 on which an LED (light source) 510 is mounted, a wiring 310, a light shielding member 520, and a light guide member 530. The illumination device 5 includes an LED 510, a light shielding member 520, and a light guide member 530.

  The first case 101 is made of a non-light-transmitting synthetic resin, and is integrally formed with the light shielding member 520 seamlessly by molding. Further, as shown in FIG. 4, the first case 101 is integrated with a metal plate 103 by insert molding. The plate 103 plays a role of improving the strength of the first case 101 and improving the dimensional accuracy of the first case 101 and the light shielding member 520 when the first case 101 is molded. The display unit 110 described above is fixed to the first case 101.

  The second case 102 is made of a non-light-transmitting synthetic resin, and is attached to the first case 101 so as to close the first case 101 from above. The second case 102 is formed with an opening window 550 that is disposed above the light blocking member 520 and the light guide member 530 and fits with the convex portion 531 of the light guide member 530.

  As shown in FIG. 3, the first substrate 120 is formed to have an outer shape along a part of the side surface of the light shielding member 520, and is fixed to the first case 101. A first connector 121 for connecting the wiring 310 is provided on the first substrate 120.

  The wiring 310 includes a plurality of coaxial thin wires (not shown) and connectors (not shown) provided at both ends thereof. One end of the wiring 310 is connected to the first connector 121 of the first substrate 120. The wiring 310 extends from the first connector 121 so as to bypass the light shielding member 520, and is bundled and inserted into the hinge device 300 along the Y axis as shown in FIG. Further, the wiring 310 is inserted through the second casing 200 along the X axis. The other end of the wiring 310 is connected to the second connector 221 of the second substrate 220 housed in the second housing 200.

  As shown in FIG. 5, the LED 510 is disposed adjacent to the light shielding member 520 and the light guide member 530 on the upper surface of the first substrate 120.

  The light shielding member 520 is formed integrally with the first case 101 and is made of a non-light-transmitting synthetic resin. The light shielding member 520 is formed with a recess 521 that fits with the side surface of the light guide member 530. Note that the light shielding member 520 does not overlap the wiring 310, the light shielding member 520, and the light guide member 330 in the vertical direction (the thickness direction of the first housing 100), and bypasses the light shielding member 520. invite.

  The light guide member 530 has a side surface that fits into the recess 521 of the light shielding member 520. Further, on the upper surface of the light guide member 530, a convex portion 531 having a side surface that fits with the opening window portion 550 (see FIG. 3) of the second case 102 is formed. The light guide member 530 is fixed to the second case 102 by a double-sided tape 540 shown in FIG.

  Next, the path of light emitted from the LED 510 will be described.

  As shown in FIG. 5, the light emitted from the LED 510 is incident on the light guide member 530 from the cutout portion of the light shielding member 520 to the concave portion 521.

  The light incident on the light guide member 530 is guided substantially parallel to the first substrate 120 according to the shape of the light guide member 530 and is shielded by the light shielding member 520 on the side and lower surfaces of the light guide member 530. The light is emitted from the upper surface of the member 530.

  Light emitted from the upper surface of the light guide member 530 is blocked by the second case 102 except for light passing through the opening window 504 of the second case 102, that is, light emitted from the convex portion 531.

  As described above, the illumination device 5 guides the light emitted from the LED 510 to the opening window 504 by the light guide member 530 and shields the guided light by the light shielding member 520 and the second case 102. Thus, a visible display is generated on the opening window 504 while preventing light leakage.

  According to the illumination device 5 having the above configuration, the configuration can be simplified by integrally forming the light shielding member 520 for preventing light leakage and the first case 101. Thereby, specifically, for example, the number of parts can be suppressed and the manufacturing cost can be suppressed.

  Moreover, the visibility of the illumination device 5 can be improved by providing the light guide member 530 that guides the light from the LED 510 to the opening window 550. Moreover, the freedom degree of arrangement | positioning with LED510 and the opening window part 550 can be improved.

  In addition, the first casing 100 can be thinned by extending the light guide member 530 from the vicinity of the LED 510 substantially in parallel with the first substrate 120.

  Further, the wiring 310 is guided by the light shielding member 520, and the light shielding member 520 is bypassed so as not to overlap the light shielding member 520 and the light guide member 530 in the vertical direction (thickness direction of the first housing 100). One casing 100 can be further thinned. This is advantageous when the wiring 310 is composed of a plurality of coaxial thin wires and it is difficult to suppress the thickness thereof as in the case of a flexible substrate wiring. In particular, when the wiring 310 is inserted into the second casing 100 via the hinge device 300 and connected to the second substrate 220 accommodated in the second casing 100, the wiring 310 is bundled. Since the thickness becomes large, it is advantageous. In addition, since it is not necessary to add additional parts, manufacturing costs can be reduced. Further, the assembly of the first housing 100 can be facilitated.
