However, the conventional LED
In the lens mounting structure, since the LED lens 2 is press-fitted into the hole 8 of the front case 1, it is required to adjust and manage the external dimensions of the LED lens 2 with high accuracy. Further, since the assembling work by press fitting takes time, there is a problem that production efficiency is poor.

[0007] Further, the light emission of the LED is L
Since the light can only be seen through the ED lens, the light emission of the LED may be overlooked.

The present invention solves such a conventional problem, in which an LED lens can be easily incorporated.
In addition, not only the LED lens but also L
It is an object of the present invention to provide a telephone capable of simultaneously illuminating a CD panel and to provide a method for incorporating the lens.

[0009]

Therefore, according to the present invention, after a lens is incorporated into a hole of a telephone case, an LCD panel is fixed to the case, and a part of the lens is sandwiched between the LCD panel and the case. Then, the lens is positioned.

[0010] Therefore, the mounting of the lens is facilitated, and the requirement for the accuracy of the external dimensions of the lens is relaxed.

Further, in the present invention, the LCD panel is brought into contact with the lens, and the light reaching the lens is guided to the LCD panel from the contact surface. In addition, the LCD panel and the lens are integrally molded, and the light reaching the lens is
Led to the panel.

[0012] Therefore, as the light-emitting body emits light,
The panel and the lens can shine together.
