が得られる。According to the present invention, a flange of a cylindrical light guide having a flange at the bottom is formed into a hollow cylindrical shape made of an elastic material such as rubber or plastic provided in a light emitting element mounting portion of a printed circuit board on which the light emitting element is mounted. It is held by the light guide body and the printed circuit board is attached to the case that partially has a light-transmitting part, so that the light guide body is elastically held and the light of the light emitting element is transmitted through the light guide body. Not only does the expensive LED with flange and the dedicated LED holder become unnecessary, but various effects as described below can be obtained.
（１）導光体受けが導光体のフランジを受ける際に弾性
変形するので、プリント基板を筐体に取りつける際のＸ
・Ｙ方向の位置精度のばらつきを吸収できる。(1) Since the light guide receiver is elastically deformed when receiving the flange of the light guide, X when mounting the printed circuit board on the housing.
・ Can absorb variations in position accuracy in the Y direction.
（２）また、高さ方向の取付精度のばらつきも導光体受
けの弾性変形により吸収できる。(2) Also, variations in mounting accuracy in the height direction can be absorbed by elastic deformation of the light guide receiver.
（３）導光体受けが導光体のフランジを弾性的に保持す
るので、導光体は上向きの力で支えられ、筐体に接着す
る必要がない。(3) Since the light guide holder elastically holds the flange of the light guide, the light guide is supported by an upward force and does not need to be adhered to the housing.
（４）機種変更による筐体高さの違いについては、導光
体受けの高さの変更により対応可能なので、機種変更に
対する設計の対応が容易である。(4) The difference in the housing height due to the model change can be dealt with by changing the height of the light guide receiver, so that the design can be easily adapted to the model change.
（５）一般市販のプリント基板直接マウントタイプのＬ
ＥＤが使用可能であり、コストダウンが計れる。(5) General commercial printed circuit board direct mount type L
The ED can be used, and the cost can be reduced.
（６）ＬＥＤを一種類に限定せず、数種類のＬＥＤに対
応できる。(6) The number of LEDs is not limited to one, and several types of LEDs can be supported.
（７）チップタイプのＬＥＤを使用した場合、片面プリ
ント基板が使用できるので、コストダウンが計れる。(7) When a chip type LED is used, a single-sided printed circuit board can be used, so that cost reduction can be achieved.
（８）ＬＥＤが導光体受け内にあり、導光体は筐体の開
孔で覆われるので、不要な光洩れがない。(8) Since the LED is inside the light guide holder and the light guide is covered by the opening of the housing, unnecessary light leakage does not occur.
（９）ＬＥＤが筐体表面に露呈せず、ま導光体とも接し
ていないので、静電気によるＬＥＤの破壊が生じない。(9) Since the LED is not exposed on the surface of the housing and is not in contact with the light guide body, the LED is not destroyed by static electricity.
