not be used for hand WK flight too large with wireless microphones that are currently
emphasized There is a demand for small size. However, if it is made small, one bad effect will
occur. If you want to make a small size wireless miter, the wireless mic itself has a built-in
capacitor miter, electronic circuit, etc., but the wireless mic itself can not write the power switch
to open and close the power supply. There is a drawback. If this power supply switch can be
made extremely small IJIK and it can be incorporated into the main body of i-ita, the abovementioned drawbacks will be solved for a while, but this time the reliability is lowered by making
the power switch ultra small. Therefore, even if such a switch is isolated, such a small wireless
miter's power switch r: providing it is not a good idea. In consideration of such an issue, the
wireless 11)]-When a normally closed +-type electrode switch is incorporated in the miter main

As described above, the reed switch swI itself is very small, so that the main body III can be
configured in a small size. However, in this case, reed switch 8W. Because it is one that is
configured to be a normally closed switch and uses a nine reed switch, while the wireless miter is
not in use, the contact pieces (31a, 31b) of this reed switch 8wl are forced to bite , There is a
need to open the + power path. Next, this configuration will be described. In FIG. 31, (A) shows a
housing of the wireless microphone main body 1 ·, and a small wireless microphone device T is
configured by the housing (1) and the main body II. The storage body (d) is selected so that the
box-shaped mouth with the storage recess (21 heat) and the lid (2) and the paper storage recess
(21 同 じ) have substantially the same shape as the main body. In addition, the main body 11with the clip σ ◆ facing upward is usually stored. Therefore, if the bottom of the storage recess
(Ha) is arranged so as to face the reed switch at a bottom 11 of the storage recess (Ha), the main
body 4 is stored in (6) total 3). The reed switch Filnio elastic contact piece (movable equal piece)
(31 m) is made to be attracted by browsing. The reed switch 8W1 is automatically turned off
when the Me piece (31 crush (31b) of the reed switch FN1 is bitten and the main cap is stored).
Among them, the 21st is a cushioning material. In addition, in the example of H2 閏 in the case of

be formed in a small ffi (a normally closed switch (this reed switch is made The swI automatically
or exactly holds the main body 11 (by storing it) automatically, so that the battery (8) is not
wasted. Therefore, it is extremely suitable to be applied as a to-type wireless microphone which
is used by being attached to the chest pocket etc. of the user in various venues, one set of
television, etc. Since the reed switch 腑 is configured as a normally closed switch, the reed switch
FIW 1-bX is turned off even if an external wisdom is added during use (7) λ · シ J) 7 // There is
no such thing, and it is rich in credibility as well, and this reed switch history is built in the body
α11, and the operation knob to turn the switch on and off is not provided outside the case t1>
Therefore, in addition to the horn that can form the main body cl into a more cabin, there is no
fear that the function as a wireless microphone due to an erroneous switch will be stopped.
In addition, since the above-described wireless microphone typeface ・ Je is small and non-zero,
it is mainly used in the state of being stored in one pocket of a user, etc., which has been
described above. When it is desired to use the microphone as the wireless microphone, for
