2. Description of the Related Art Conventionally, in a light emitting / receiving section of a portable telephone, a case having an opening, a light guide member provided in the opening, and light incident on the light guide member provided in the case. Some include light emitting diodes (light sources). In this case, at the time of a non-incoming call, the light guide member is in a non-light emitting state to turn off the light emitting diode, while at the time of an incoming call,
The light emitting diode is turned on and off, and the colored emission light is emitted to the outside of the case through the light guide member. Thereby, the user can visually recognize that the light guide member blinks with the colored emission light.

[0003]

However, in the above-mentioned incoming light emitting section of the portable telephone, as described above, since the light emitting diode is turned off when there is no incoming call, the light guide member is in a non-light emitting state, and the novelty of appearance is improved. Lack. Therefore, the present inventor paid attention to the fact that the light guide member is in a non-light emitting state at the time of non-incoming call, and examined improvement of novelty of appearance at the time of non-incoming call.

According to the study of the present inventor, a light emitting diode, together with a transparent member and a light reflecting film (for example, a half mirror film) disposed inside the case with respect to the transparent member, is provided in the opening of the case. Was arranged inside the case with respect to the light reflecting film.

In this case, the light emitting diode is turned off when there is no incoming call, but light (external light) incident on the transparent member from the outside into the opening of the case is reflected by the light reflecting film and becomes transparent. The light exits from the opening of the case through the member. This allows the user to visually recognize that the transparent member is shining when there is no incoming call, so that a novel appearance can be obtained.

On the other hand, when an incoming call arrives, the light emitting diode is turned on and off, and the colored light is made to enter the transparent member through the light reflecting film, so that the transparent member is turned on and off by coloring. However, when flashing the light emitting diode,
Although a part of the colored light reaches the transparent member through the light reflecting film, the amount of the colored light reaching the transparent member is very small. For this reason, sufficient luminance with colored light was not obtained in the transparent member, and clear blinking with colored light in the transparent member was not visually recognized.
