摘要:
This invention provides a portable terminal apparatus increasing brightness at a light emitting portion of the portable terminal apparatus. Light emitted from a light source is made to be incident from an engaging portion of a conducted light emitting portion and is diffused at inside of the conducted light emitting portion. The diffused light is reflected by surfaces of a bottom face portion and side face portions and of a recessed portion, the reflected light is further diffused and emitted by a conducted light emitting member at a vicinity of a surface of the recessed portion and therefore, brightness of the conducted light emitting portion at the vicinity of the recessed portion can be increased.
技术问题语段:
Therefore, although a user of the portable terminal apparatus is informed of various alarms of signal arrival and the like by lighting the conducted light emitting portion, there is conceivable a problem that even when the above-described portion having high brightness of the conducted light emitting portion is assumedly concealed by some obstacle (finger, hand or the like) and the portion having low brightness is exposed, a user does not notice informing of signal arrival or the like since the brightness of the exposed portion is low.|Further, although it is conceivable to reduce the low brightness portion of the conducted light emitting portion by emitting light to the conducted light emitting portion by increasing a number of pieces of the light source, the increase in the light source not only increases fabrication cost of the portable terminal apparatus but constitutes a factor increasing power consumption of the portable terminal apparatus.

权利要求:
What is claimed is: 1. A portable terminal apparatus comprising: a first housing; and a light emitting portion provided in the first housing and including a light source and a conducted light emitting portion for conducting a light from the light source and emitting the conducted light; wherein the conducted light emitting portion includes a conducted light emitting member containing a light diffusing agent, and wherein a surface of the conducted light emitting portion includes an exposed face having a recessed portion exposed on a surface of the first housing. 2. The portable terminal apparatus according to claim 1, wherein a surface of the recessed portion includes projections whose height is lower than a depth of the recessed portion. 3. The portable terminal apparatus according to claim 1, wherein a surface of the recessed portion includes a surface portion formed in such a manner that a normal line of the surface portion and an optical axis of the light source meet with each other at a predetermined angle other than 90.degree.. 4. The portable terminal apparatus according to claim 1, further comprising: a reflective film for reflecting the light from the light source and provided on a face opposed to the exposed face of the conducted light emitting portion. 5. The portable terminal apparatus according to claim 1, wherein the conducted light emitting portion includes an engaging portion engaged with the first housing, and wherein the light from the light source is incident on the engaging portion. 6. The portable terminal apparatus according to claim 1, wherein the conducted light emitting portion is arranged to continuously extend over at least two surfaces of the first housing. 7. The portable terminal apparatus according to claim 1, further comprising: a hinge portion; and a second housing connected with the first housing through the hinge portion, wherein the first housing and the second housing are pivotable with respect to each other on an axis core of the hinge portion, and wherein the conducted light emitting portion is arranged at an area which is not covered by the second housing on a surface of the first housing opposed to the second housing in a state that the portable terminal apparatus is folded at the hinge portion. 8. The portable terminal apparatus according to claim 4, further comprising: a colored layer provided between the reflective film and the conducted light emitting portion. 9. The portable terminal apparatus according to claim 4, further comprising: a printed layer printed with a predetermined figure and provided between the reflective film and the conducted light emitting portion.
