Description of the Related Art In pre-play, interlude and accompaniment parts, which are sung according to those recorded by an orchestra, so-called karaoke, the singer has a microphone, but this microphone also sings while moving around. Because of the inconvenience, many cordless types are becoming popular. At first, the cordless type used radio waves at the beginning, but recently it is an optical type that uses infrared rays for reasons such as crosstalk in places like a karaoke room that is partitioned by one wall. The number of such microphones is increasing

する。In a karaoke room, which often sings while moving around, it is necessary to place light receiving sensors at every corner of the room so that infrared signals can be received well.
Furthermore, a plurality of light emitting diodes are provided at the base of the microphone so that the microphone is not disabled no matter how it is tilted. At least the head of the light emitting diode is made of transparent synthetic resin, and the head made of the synthetic resin emits light rays at a predetermined radiation angle.

る。FIG. 3 shows a light emitting diode which emits infrared rays. In this light emitting diode 1, a head 3 made of synthetic resin is provided at the tip of a metal stem 2, and a chip (not shown) is provided inside the head 3. The chip emits infrared rays when energized. Four
Is an electrode pin. 4 and 5 show a conventional structure in which the light emitting diode 1 having such a structure is arranged at the base of a microphone. In this case, when the light emitting diode 1 is mounted on the substrate 5, each of them is directed outward by the spacer 6. By directing the infrared rays outward, the emitted infrared rays 7 are diffused and radiated from the light emitting portion 9 formed in a cylindrical shape by a transparent material at the base of the microphone body 8.

In this case, the spacers are not used, and all the light emitting diodes 1 are directly attached to the substrate 5 in the same direction (axial direction of the microphone body 8). A mushroom type reflecting mirror 10 as shown in the drawing is provided at the center of the light emitting diode 1 arranged in a ring shape. In this structure, the infrared rays 7 emitted in one direction are reflected by the reflecting mirror 10.

付け工数が多くなる問題があった。In the structure shown in FIGS. 4 and 5, the spacer 6 is indispensable, and there is a problem that the number of parts and the number of assembling steps increase. This is because the wireless microphone is used in a harsh condition and sometimes drops onto the floor. Therefore, simply mounting the light emitting diode 1 on the substrate 5 may change the direction. On the other hand, in the structure shown in FIG. 6 and FIG.
Is required, and this also has a problem that the number of parts increases and the number of assembling steps increases.

寸法が大きくなる。The light emitting diode 1 has a large outer dimension and a small outer dimension even if they have the same performance. The large mold is a mold in which the entire part including the head is molded with a synthetic resin without using a metal stem. Therefore, it can be manufactured at a lower cost than the small one, and there is a large price difference between the two. Therefore, if there is no problem in terms of dimensions as an element, an inexpensive large-sized element will be used.
By the way, in the case of using this large-sized one, if the structure shown in FIG. 4 and FIG. The outer diameter dimension of 9 also becomes large. The structures shown in FIGS. 6 and 7 increase the overall length dimension.

It is an object of the present invention to provide an infrared wireless microphone in which the outer diameter dimension and the overall length dimension of the light emitting section 9 are not increased and the size is almost the same as when the light emitting diode 1 having a small outer dimension is used.

い。BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to FIGS. The light emitting diode 1 is attached to the substrate 5 so that the head portion 3 is inclined toward the side of the light emitting diode 1 which is adjacent to the substrate 5. In order to mount the light-emitting diodes 1 in this manner, the light-emitting diodes 1 are first mounted on the substrate 5 in an upright posture, and external forces are applied to the light-emitting diodes 1 to sequentially tilt the light-emitting diodes 1 toward the adjacent light-emitting diodes 1. Light emitting diode 1
In order to facilitate tilting, the light emitting diode 1 may be tilted in a direction perpendicular to the surface formed by the two electrode pins 4.

る。When the light emitting diode 1 is tilted in this way,
Infrared rays emitted from each light emitting diode 1 are directed outward with respect to the axis of the microphone body 8, and as a result, the same action and effect as those shown in FIGS. 4 and 5 can be obtained. Moreover, since the spacer is not used, the outer diameter dimension D as a whole is small, which is comparable to that using the small light emitting diode 1.

It can fit in the size of. Since the light emitting diode is tilted, infrared rays can be emitted in a target direction without using a reflecting mirror or the like.
