Description

  The present invention relates to a portable wireless device including an antenna and a light emitting unit in the vicinity of an end of a casing.

In a portable terminal, if an electronic component is arranged near the antenna, the antenna performance is affected. For example, it is difficult to arrange a light emitting unit for notification at the time of incoming call or charging near the antenna. In a foldable portable terminal, the light from the light emitting unit in the operation unit casing is applied to the end of the operation unit casing opposite to the antenna and not covered by the display unit casing even in the folded state. Patent Document 1 discloses an arrangement in which a guiding light guide plate is arranged. Further, Patent Document 2 discloses an antenna that is built sideways at the end of a housing.

  For example, in the case where the antenna is mounted horizontally at the end of the case, let the light from the light emitting part mounted on the board be separated from the antenna side by the distance to avoid the influence on the antenna performance. It can be considered. In that case, the light guide member has a complicated three-dimensional shape that extends from the light emitting portion on the substrate to the end of the housing over the antenna, and there is a concern that a sufficient light guide function cannot be obtained. .

  An object of the present invention is to guide the arrangement of a light emitting unit in a portable wireless device having an antenna and a light emitting unit in the vicinity of the casing end, and guide light from the light emitting unit to the casing end through the antenna. It is to secure the light guiding function by making the member a simple shape.

  In order to solve the above-described problems, the invention described in claim 1 includes an antenna disposed horizontally in an end portion of a housing, and a light emitting portion disposed on a shield case fixed on a substrate disposed in the housing. And a light guide member that guides light emitted from the light-emitting portion to the end of the housing substantially linearly beyond the antenna.

  The invention according to claim 2 is the portable wireless device according to claim 1, wherein the operation unit casing and the display unit casing are foldably coupled to each other at a hinge portion, and the hinge portion of the operation unit casing The antenna, the light emitting unit, and the light guide member are built in the opposite end, and the light emitting unit is mounted on a key board disposed on the shield case.

  A third aspect of the present invention is the portable wireless device according to the first or second aspect, wherein the light guide member is covered around the light guide member, and the outer surface is a light shielding surface and the inner surface is a light reflecting / diffusing surface. A tape is provided.

  According to the present invention, the light guide function can be ensured by making the light guide member that guides the light emitted from the light emitting unit beyond the antenna to the end of the casing into a simple substantially linear shape.

Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a folded state of a mobile phone as a configuration of an embodiment of a portable radio device to which the present invention is applied. A foldable portable device in which an operation unit casing 1 and a display unit casing 2 are coupled by a hinge unit 3. In the telephone, a light emission notification unit 4 is provided in the center of the end of the operation unit housing 1 opposite to the hinge unit 3 for notification at the time of incoming call or charging.

  FIG. 2 is a plan view of the operation unit housing 1, 5 is an operation unit using various operation keys, and 6 is a backlash pressing member. In the folded state shown in FIG. 1 of the cellular phone, the backlash pressing member 6 abuts against the display unit housing 2 in a protruding state from the operation unit housing 1 in the width direction, and the hinge unit 3 of the display unit housing 2 Press the rattle near the opposite end.

  FIG. 3 is a central longitudinal cross-sectional view taken along the line AA in FIG. 2, and radio waves in a predetermined frequency band are transmitted and received in the end portion on the opposite side to the hinge portion 3 of the operation unit casing 1 for transmission and reception. A plate-like antenna 7 is arranged with its plate surface sideways. Inside the operation unit housing 1 is disposed an LED 8 that forms a light emitting unit for incoming / charging notification at a distance from the antenna 7 so as to avoid an influence on the antenna performance, and emits light from the LED 8, A light guide member 9 having a substantially linear shape leading to the end of the housing beyond the antenna 7 is disposed. The tip of the light guide member 9 functions as the light emission notification unit 4.

  The operation unit housing 1 is configured by combining a lower case 11 and an upper case 12, and inside the lower case 11 is a main board 13 and various electronic components and electronic circuits mounted on the main board 13. A shield case 14 covering the entire periphery is fixed. A flexible key substrate 15 is overlaid on the shield case 14, and the LED 8 is mounted at the center of the end of the flexible key substrate 15.

  FIG. 4 is an enlarged view of the vicinity of the end of the antenna 7 in FIG. The light guide member 9 is made of a transparent resin and has a plate shape so as to increase the thickness of the incident side to increase the incident light. A concave step 9b is provided in the middle of the light guide member 9, and the thickness of the tip portion is increased. The light emission notification unit 4 formed by increasing the thickness of the upper case 12 is exposed to the outside through a slit extending from the end surface and the upper surface formed at the center of the end cover 16 coupled to the end of the upper case 12. A light shielding tape 19 is covered around the light guide member 9. Note that the backlash pressing member 6 is disposed in a notch extending in the width direction formed at an end portion along the end cover 16 of the upper case 12.

  FIG. 5 is an exploded perspective view showing the light guide member 9 and the light shielding tape 19 in an enlarged manner. The light guide member 9 having a substantially flat plate shape has light incident from the LED 8 at the center of the end opposite to the light emission notification unit 4. The portion 9a is formed in a protruding shape, and a concave step portion 9b that avoids the antenna 7 is formed on the lower surface. The light shielding tape 19 has a black light shielding surface 19a on the outer surface and a light reflecting / diffusing surface 19b on the inner surface, which is adhered and covered around the plate-shaped light guide member 9. .

  As described above, in the foldable mobile phone, the light emitting notification unit 4 exposed over the end surface and the upper surface of the center of the operation unit housing 1 opposite to the hinge unit 3 emits light, so that the folded state shown in FIG. Even when it is open, it can be seen that there was an incoming call or charging.

  In addition, the light emission notification unit 4 at the center of the end of the operation unit housing 1 emits light from the LED 8 mounted on the flexible key substrate 15 on the shield case 14 on the main substrate 13 as shown in an enlarged view in FIG. Light emission is performed by illuminating the light emission notification unit 4 formed by increasing the thickness of the tip portion through the light guide member 9 having a substantially linear shape avoiding the antenna 7 by the concave step portion 9b. Accordingly, the LED 8 is arranged at a distance so as not to affect the antenna performance with respect to the antenna 7 arranged with the plate surface in the end opposite to the hinge portion 3 of the operation unit casing 1. In addition, at the end of the operation unit housing 1 where the antenna 7 is placed sideways, a light emission notification at the time of incoming call or during charging can be performed.

  Then, the light guide function of the light guide member 9 is enhanced by the light shielding tape 19 covered with the light guide member 9 with the outer surface as the light shielding surface 19a and the inner surface as the light reflecting / diffusing surface 19b, and the thickness of the tip portion is increased. The illumination performance of the light emission notification unit 4 formed to be thick can be further enhanced.
