Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technology for illuminating an exterior of an electronic device such as a portable telephone.

[0002]

2. Description of the Related Art In recent years, for an electronic device such as a portable telephone, a device in which an outer case is lighted up has been proposed to promote sales effects. This type of electronic device is used according to the user's preference, such as shining a label attached. Also, if the outer case is made to shine even in a dark place, even if it is dropped, it can be immediately searched for, which is very convenient.

[0003] By the way, in the above electronic devices, reduction in size and weight and reduction in power consumption have been promoted. Therefore, to light up the outer case, LED
(Light Emitting Diode) and so on, as well as power for the number of mounted LEDs, are a major obstacle to reducing the size and weight of electronic devices and reducing power consumption. Was.

[0004]

As described above, in the above-described electronic apparatus, it is necessary to mount a large number of LEDs in order to light up the outer case, and it is necessary to consume power correspondingly. Conventionally, there has been a strong demand for a method capable of realizing effective light-up while maintaining small size, light weight and low power consumption.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an electronic device capable of realizing an effective light-up while maintaining a small size, light weight and low power consumption.

[0006]

An electronic apparatus according to the present invention includes an electronic apparatus main body containing a display, a light source provided inside the electronic apparatus main body and generating light, and a light generated from the light source. A light guide plate for guiding to the display, and a holding portion for holding at least the display and the light guide plate, and a first hole for exposing the light guide plate to at least a part of the holding portion around the light guide plate holding position. The second hole is formed at a position of the electronic device main body which is formed and faces the first hole.

That is, according to the present invention, the light guide plate is covered with the holding portion so as to prevent light from leaking to each part other than the display through the light guide plate, so that light to the outside is blocked. A first hole for exposing the light guide plate is formed in at least a part of the periphery of the light guide plate accommodating position of the holding portion, and a second hole is formed at a position of the electronic device main body opposite to the first hole. In this way, light leaked from the light guide plate is guided to the second hole via the first hole.

Therefore, according to the present invention, only by attaching a transparent printing member to the second hole on the electronic device main body, it is not necessary to add a separate light source, and the light-up effect of the electronic device main body is enhanced. In addition, since it is not necessary to provide a light source at a place where light-up is desired, a reduction in size and weight and a reduction in power consumption can be maintained.

An electronic apparatus according to the present invention includes: an electronic apparatus main body accommodating a display; a light source provided inside the electronic apparatus main body for generating light; and a light generated from the light source.
A light guide plate for guiding to the display, and a holding portion for holding at least the display and the light guide plate, a first hole is formed in at least a part of the periphery of the display housing position of the electronic device body, and the holding portion At least one end of the light guide plate to be held is first.
Characterized by having a shape extending so as to face the hole.

That is, according to the present invention, a hole is provided in a portion of the electronic device main body that is to be lighted up around the display accommodating position, and one end of the light guide plate for guiding light from the light source to the display is formed with a hole in the electronic device main body. The light source provided in the hole is shared with the light source for the display so as to extend to the position.

Therefore, according to the present invention, it is not necessary to separately provide a light source at a portion to be lighted up, and furthermore, not only a hole is provided at that portion, but also one end of the light guide plate is extended through the hole. Since it is shared with a dexterous light source, it is possible to enhance the light-up effect of the electronic device body only by providing a transmissive member at a place to be lighted up, and further, it is not necessary to provide a light source at that place. Accordingly, it is possible to maintain a reduction in size and weight and a reduction in power consumption.

Further, in the electronic device according to the present invention,
A plastic member is used for the light guide plate. For this reason,
When it is necessary to bend the light guide plate at a substantially right angle when extending the light guide plate to a position to be lighted up, the light guide plate can be easily bent by using a plastic member. Further, since the plastic member itself is a lightweight member, it can contribute to the reduction in size and weight of the device.
