It is. Note that the LED 28 is located on the inner surface side of the central region 262 of the rear case 26, and therefore cannot be visually recognized when the rear case 26 is viewed from the front side outside the first housing 101 in the rear case 26. Therefore, in FIG. 3, the LED 28 is surrounded by a dotted line.

FIG. 5 is a cross-sectional view taken along line CC ′ shown in FIG.
As shown in FIG. 5, a light guide plate 24 is disposed on the outer surface of the first housing 101 in the end region 263 of the rear case 26 via a double-sided tape 25. The light guide plate 24 has an inclined surface 241 that is inclined toward the end region 211 side of the rear plate 21 on the inner side surface of the first housing 101. The outer surface of the first housing 101 in the end region 263 of the rear case 26 to which the double-sided tape 25 is bonded is also formed with an inclined surface inclined with substantially the same inclination.

The double-sided tape 25 is formed of a member having a high light diffusivity / reflectance (for example, a member colored in white) and constitutes the light diffusion portion 251.
A rear plate 21 is disposed on the outer surface of the first casing 101 in the rear case 26 via a double-sided tape 22 and a double-sided tape 23. That is, the rear plate 21 is bonded to the double-sided tape 22 having the first extension part 221 that extends to the opening 261 with the center area 212 bonded to the center area 262 of the rear case 26. The end region 211 is bonded to the double-sided tape 23 bonded to the outer surface of the first housing 101 in the light guide plate 24, thereby being disposed on the outer surface of the first housing 101 in the rear case 26. Is done.

  The central region 212 of the rear plate 21 is formed of a member having a low light transmittance (for example, a member colored with a black color having a low light transmittance) and constitutes a light blocking portion 214. . Further, the double-sided tape 22 bonded thereto is also formed of a member having a low light transmittance (for example, a member colored in black), and the light shielding portion 222 (in the second light shielding portion of the present invention). Configure). On the other hand, the end region 211 of the rear plate 21 is formed of a member having a high light transmittance (for example, a transparent or translucent member) and constitutes a light transmitting portion 213. In addition, the double-sided tape 23 bonded to the end region 211 is also formed of a member having a high light transmittance (for example, a transparent or translucent member), and the light transmitting portion 231 (in the second light transmitting portion of the present invention). Configure).

On the other hand, the flexible substrate 27 extends to a facing portion 271 that faces the inner surface of the first housing 101 in the central region of the rear case 26 and a second portion 261 that is formed in the rear case 26. The extension part 272 is formed on the inner side of the rear case 26 so as to be formed. In addition, an LED 28 is disposed on the outer surface of the first housing 101 in the second extending portion 272. Note that the LED 28 has a flexible substrate 27 such that the light irradiation surface 281 on which light is actually irradiated faces the width direction of the first casing 101, that is, the central region 262 of the rear case 26 toward the end region 263. The second extension portion 272 is mounted.

The flexible substrate 27 will be described in more detail with reference to FIG.
FIG. 6 is a view of the flexible substrate 27 on which the plurality of LEDs 28 are mounted as viewed from the front side on the outside of the first housing 101.
As shown in FIG. 6, a ground pattern 273 (third light according to the present invention) as a noise countermeasure around the flexible substrate 27 is provided in a region corresponding to the LED 28 in the second extending portion 272 of the flexible substrate 27. Corresponding to the diffusion part).
The ground pattern 273 is a pattern formed of a glossy metal member such as copper having a high light diffusivity / reflectance. The ground pattern 273 is electrically connected to the reference potential. Although not shown, the ground pattern 273, in a state of being disposed in the first housing 101, is brought into contact with the internal side surface of the first housing 101 in the light guide plate 24.

Next, a path through which light emitted from the LED 28 passes will be described with reference to FIG. FIG. 7 is a cross-sectional view taken along line CC ′ shown in FIG. 4 as in FIG.
As shown in FIG. 7, the irradiation surface 281 of the LED 28 is mounted on the second extending portion 272 of the flexible substrate 27 so as to face the width direction of the first housing 101. Is efficiently incident on the light guide plate 24 facing the irradiation surface 281 of the LED 28.
The light incident on the light guide plate 24 is guided to the light diffusion portion 251 of the double-sided tape 25 while being diffused to the light guide plate 24. In particular, the light guide plate 24 is formed with an inclined surface 241 on the inner surface of the first housing 101 that is bonded to the double-sided tape 25, so that the light incident on the light guide plate 24 is incident on the double-sided tape 25. The light is efficiently guided to the light diffusion portion 251 and the end region 211 of the rear plate 21.

Since the light diffusing unit 251 is formed of a material having a high light diffusivity / reflectance, the light incident on the double-sided tape 25 through the light guide plate 24 is reflected by the light diffusing unit 251 on the rear plate 21. The light is further diffused / reflected in the direction of the transmissive portion 213 and is incident on the light guide plate 24 again so as to face the thickness direction of the first housing 101. Then, the light incident on the light guide plate 24 again is guided to the outside of the first housing 101, and as a result, is incident on the light transmitting portion 231 of the double-sided tape 23. Since the light transmission part 231 is formed of a material having a high light transmittance as described above, the incident light is incident on the light transmission part 213 of the rear plate 21 without being blocked. Since the light transmission part 213 of the rear plate 21 is also formed of a member having a high light transmittance, like the light transmission part 231 of the double-sided tape 23, the light incident on the light transmission part 213 is almost blocked. Without being emitted to the outside of the first housing 101.

On the other hand, the light irradiated from the irradiation surface 281 of the LED 28 is not incident on the light guide plate 24 but directly irradiated toward the outside of the first housing 101 without passing through the light guide plate 24. Or what is irradiated toward the inside of the 1st case 101 is also contained.
However, since the light irradiated directly from the LED 28 toward the outside of the first housing 101 is incident on the double-sided tape 22 and the rear plate 21 formed of a member having low light transmittance, Most of them are blocked by the tape 22 and the rear plate 21.
In addition, light emitted directly from the LED 28 toward the inner side of the first housing 101 is incident on the second extending portion 272 of the flexible substrate 27, but is incident on the second extending portion 272. Since the ground pattern 273 having a high light diffusivity / reflectance is formed, the light incident on the second extending portion 272 of the flexible substrate 27 is diffused in the direction of the light guide plate 24 by the ground pattern 273. After being reflected, the light is then radiated to the outside of the first housing 101 along the same path as the light that is directly incident on the light guide plate 24 from the LED 28. Since the ground pattern 273 and the light guide plate 24 are in contact with each other, the light diffused and reflected in the direction of the light guide plate 24 by the ground pattern 273 is efficiently incident on the light guide plate 24.
To summarize the above, the light emitted from the LED 28 is mainly along the path of the light guide plate 24, the double-sided tape 25, the light guide plate 24, the double-sided tape 23, and the rear plate 21, as shown by the arrow D. The light is efficiently radiated to the outside of the first housing 101.

FIG. 8 is a view showing how the light emitted from the LED 28 and radiated to the outside of the first housing 101 is visually recognized from the outside. FIG. FIG. 8B is a view of the state when light is emitted from a single LED 28 in a detached state, as viewed from the front side on the outer side of the rear case 26. FIG. 8B is a diagram with the rear plate 21 attached. FIG. 8C is a view of the state when light is emitted from one LED 28 as viewed from the outside front of the rear case 26, and FIG. 8C is a diagram in which light is simultaneously emitted from a plurality of LEDs 28 with the rear plate 21 attached. It is the figure which looked at the mode when irradiated from the external side front of the rear case 26. FIG.

As shown in FIG. 8A, the openings 261 of the rear case 26 are formed substantially radially around the LEDs 28 under the control of the control unit of the flexible substrate 27. For example, as shown in FIG. The light emitted from the LED 28a shown is diffused radially by the light guide plate 24 and the light diffusion part 251, and as a result, the part shown in the range E (shaded part) in FIG. Looks shining.
Then, as shown in FIG. 8B, when the rear plate 21 is attached, this light seems to shine from the front side on the outside of the rear case 26 at the portion indicated by the range F (shaded portion). Looks like.
On the other hand, as shown in FIG. 8 (c), when light is emitted from a plurality of LEDs 28 under the control of the control unit of the flexible substrate 27, the light emitted from each LED 28 is continuous with each other. As a result, the range G (shaded portion), that is, almost the entire area of the light transmitting portion 213 appears to shine from the front side on the outside of the rear case 26.

As described above, according to the mobile terminal 100 of the present embodiment, the light emitted from the LED 28 is efficiently incident on the light guide plate 24 facing the irradiation surface 281 of the LED 28, and the light incident on the light guide plate 24. Is guided to the light diffusion portion 251 of the double-sided tape 25 while being diffused to the light guide plate 24. The light incident on the double-sided tape 25 is further diffused and reflected in the direction of the light transmitting portion 213 of the rear plate 21 by the light diffusing portion 251 having a high light diffusivity / reflectance, and the thickness of the first housing 101 is changed. It again enters the light guide plate 24 so as to face, and enters the light transmission portion 231 of the double-sided tape 23. The light incident on the light transmission part 231 passes through the light transmission part 231 and the light transmission part 213 formed of a material having high light transmittance without being blocked, and is emitted to the outside of the first housing 101. Is done.
That is, in the mobile terminal 100 of the present embodiment, the light from the LED 28 is reflected / diffused by the light diffusing unit 251 and is incident on the light transmitting unit 213, so that the position of the LED 28 and the position of the light transmitting unit 213 are determined. There is no need to arrange them in correspondence. For this reason, the freedom degree of design of the light emission structure in the 1st housing | casing 101 increases, and the efficiency of a structure can be aimed at.

Further, according to the portable terminal 100 of the present embodiment, the double-sided tape 25 is formed of a member having a high light diffusivity / reflectance (for example, a member colored in white) and the light diffusing portion 251 is formed. Configure. Further, the double-sided tape 22 bonded to the central region 212 of the rear plate 21 is formed of a member having a low light transmittance, for example, a black-colored member, and constitutes a light shielding part 222. Further, the double-sided tape 22 bonded to the end region 211 of the rear plate 21 is formed of a member having a high light transmittance, for example, a transparent or translucent member, and constitutes a light transmitting portion 231.
Accordingly, the light diffusing unit 251, the light transmitting unit 231, and the light shielding unit 222 are integrally formed with the double-sided tapes 25, 23, and 22 for bonding and fixing the components of the light emitting structure, respectively. The number of parts can be reduced.

Further, according to the mobile terminal 100 of the present embodiment, the light irradiated directly from the LED 28 toward the outside of the first housing 101 is the double-sided tape 22 and the rear plate formed of a member having low light transmittance. 21, most of the light is blocked by the double-sided tape 22 and the light blocking unit 214. In addition, light emitted directly from the LED 28 toward the inner side of the first housing 101 is incident on the second extending portion 272 of the flexible substrate 27, but is incident on the second extending portion 272. Is diffused and reflected in the direction of the light guide plate 24 because the ground pattern 273 having a high light diffusivity / reflectance is formed.
Accordingly, with these configurations, the light emitted from the LED 28 guides the light to the light diffusion portion 251 of the double-sided tape 25 that reflects and diffuses the light to be emitted to the outside of the first housing 101. And light leakage to other parts can be suppressed. Thereby, the light from LED28 can be efficiently emitted outside.

Further, according to the mobile terminal 100 of the present embodiment, the light guide plate 24 is formed with the inclined surface 241 on the inner side surface of the first housing 101 that is bonded to the double-sided tape 25. Is efficiently guided to the light diffusion portion 251 of the double-sided tape 25 and the end region 211 of the rear plate 21.

  Further, according to the mobile terminal 100 of the present embodiment, the double-sided tape 22 has the first extension part 221 extended to the opening part 261, and the light extension part 221 is included in the first extension part 221. Thus, unintentional light leakage other than the intended light transmission by the light transmitting portion 231 can be prevented.

Further, according to the mobile terminal 100 of the present embodiment, the flexible substrate 27 is formed on the rear case 26 and the facing portion 271 facing the inner side surface of the first housing 101 in the central region of the rear case 26. It is arranged on the inner side of the rear case 26 so that a second extending portion 272 extending to the opening portion 261 is formed, and the extended portion has a ground having a high light reflectance and diffusivity. Since the pattern 273 is formed, the light from the LED 28 can be prevented from leaking downward, and the light incident on the extended portion can be efficiently incident on the light guide plate 24. In addition, since the ground pattern 273 has a reference potential, electrical and magnetic noise in the vicinity of the flexible substrate 27 can be prevented.
In addition, since the light emitted from the LED 28 in the housing width direction is diffused and reflected by the double-sided tape 25 in the thickness direction of the first housing 101, the LED 28 is the first with respect to the rear plate 21. There is no need to dispose the casing 101 in the thickness direction, and the first casing 101 can be suitably reduced in thickness.

The present invention is not limited to the embodiment described above.
That is, when implementing the present invention, various modifications, combinations, sub-combinations, and alternatives may be made to the components of the above-described embodiments within the technical scope of the present invention or an equivalent scope thereof.
In the embodiment described above, the mobile terminal 100 is a foldable mobile phone, but the present invention is not limited to this. As long as it is an electronic device having a light emitting structure, it may be an electronic device such as a mobile phone other than a foldable type or a PDA (Personal Digital Assistant).
