example, the applicant's proposal, and the object of the invention is to In the case of sliding on
the power switch tube which is turned on and off, it is possible to obtain a reliable switching
operation and to obtain a reliable switching operation, but various electronic devices other than
the microphone are also applicable. ill / 1. The present invention will be given with reference to
the following drawings, and a specific example of nine wireless microphones will be described.
FIGS. 1A and 1B are perspective views showing the external shape thereof. The figure shows a
wireless microphone as a whole of +11 U, which is an electret condenser type having a
substantially right cylindrical shape, a metal pipe sheathed head 111111 incorporating an
electret capsule, a low side wave amplifier, a high frequency amplifier, a modulation circuit, a
transmission circuit And a metal grip pipe (3) which encloses and inserts / removes a molded
chassis (described later) in which a battery or the like is cast and housed, a head portion (9
microphone on / off operation element (4) provided below the head portion); The antenna wire

example to be in a standby or power on state. After a while, the microphone operator (4) can be
turned on and off. Thought itself to revealing aspects of standby refuse has already been
proposed by the present applicant. +2+! 1211tjjllIIA I-1111K along the main part O enlarged
cross-sectional view, (2) in the figure (2) is a head rod, (31 is a grip pipe, 141 microphone
operator, (6) ri head portion pipe, (7) inside of a bald lip pipe The mold chassis (AB8 resin etc.)
1.8) shows the above-mentioned each circuit gold holder transmitter disposed in the housing
portion of this chassis (7), and the right side sK has a battery housing portion although not
shown. ing. The microphone operator (4) is associated with, for example, a part of the
transmission 4II 椴 (8) and is set to turn on / off its operation. In this example, the sharn (7) c of
this example comprises 7 rungs (9) on the left side of the transmitter housing in the figure, and
also extends the cylinder field of small diameter to the left. 1, the head part pipe (6) fitted in the
same 1, (a state where it can slide the mold cylinder α AB made of AB8 resin etc., the station し
く field will be referred to as inner cylinder, circle iu υ as outer cylinder), These O inner sleeve
and outer sleeve fil are slid relatively to the right along the axis gK by a predetermined stroke 疋,
and the grip pipe (3) and the head part pipe (61 1 1 3) Allowing the user to confirm that the user
is in the stampino mode by exposing the circumferential surface near the free end of the outer
cylinder a from the portion of the distance C between the two, by separating them.
Therefore, the outer cylinder a is easy to see as, for example, red, and its free end portion is fitted
to the grip (3) side, and the left end of the above-mentioned 7 rungs (9) I am getting in touch. As
described above, as is apparent, the stroke of the head (2) being pulled out during the standby
operation is constant, and the power is also turned on in the standby state. Therefore, with
reference to FIG. 2 and FIG. 4 (cross-sectional view on the line in FIG. 11), relative slides of the
inner cylinder a and the outer cylinder a in this example) First of all, at the left-right symmetric
position of the inner cylinder αQ, the free end and both sides connected to it are slipped to the
right, ie Originally, the downward facing rectangular tongue piece α 成形 is integrally formed,
and the outer surface road end of each tongue piece is formed with a locking projection @ (t 3 a)
of a substantially semicircular cross section along the width direction, The above-mentioned slide
stroke dimensions and 14] the serrated stoppers (13b) are formed on the outer surface of the
end of the above-mentioned slide stroke, and the center II (13m) and the stone / (13b) of these
are the outer circumference of the inner cylinder Q @ It is made into the state made to project
rather than direction. On the other hand, in the outer cylinder al) I'Ct; j, for example, a
rectangular hole a4 corresponding to the above-mentioned both side tongue like piece is drilled
in symmetrical position near the free end, as shown in FIG. In the initial state of the key after
sliding the a- and the outer cylinder aD, the right inner edge of each rectangular hole α threat is
locked from the tongue piece (+3 free end protrusion (13a) K) ing. Then, in the process of
drawing out the outer sleeve 111 and the head portion pipe (6) in the direction of standby and at
the end thereof, the both side tongue pieces αj are elastically bent inwardly to each other
(temporarily shown). Therefore, the right inner edge of each rectangular hole + 141 initially
locked passes over the projection (13JI) of the tongue a3, and is blocked by the rising edge of the

serrated stopper (13b). That is, both ends 1m of the grip pipe (3) and the head portion pipe (6)
have an interval C (see FIG. 1B), and the outer cylinder I (5) colored as described above within
this interval The peripheral surface in the vicinity of the O free end is exposed, and the right
inner edge of the rectangular hole α 奢 of the outer cylinder α 舌 is tongue-shaped (1: 10 clicks
again due to restitution when the head portion (2) is reactivated. Is locked. Since a slope is
attached to the outer surface of the serrated stopper (tab) of each tongue I, when inserting the
chassis side inner cylinder α value into the head 5 (2) in one assembly line, both sides Thus, the
respective tongues I are bent inward by the free end of the outer cylinder 0 and fitted so as to be
in the initial locking state as described above.
Naturally, in the standby mode, the power must be turned on. In this embodiment, as shown in
FIG. 2, in order to obtain the power-on state at the same time when the head portion (2) is pulled
out, a special slide which is turned on and off by relative sliding of the inner cylinder Q11 and
the outer cylinder a11. A switch (Is is provided to perform its intended function control.
However, the restriction to become m * of this switch is that the above-mentioned interval C (FIG.
2, FIG. 4) due to the stroke is set relatively small, therefore, in the case of this example, the power
supply 6) configure and arrange a switch acj that can turn on and off the switch securely. FIGS.
3A and 3B are perspective views provided for the explanation. By the way, + IG (16 16b)
indicates elastic contact pieces electrically connected to the two electrodes of the battery and
arranged in a row, respectively, and the free end portions Kf-J of these contact pieces are Ushaped downward as illustrated. And a short circuit for electrically connecting the am touch
piece lI8 at the position corresponding to each curve 11Q と 共 に, and this is arranged in the
direction of the arrow square. By moving, both contact pieces aQ are short-circuited to make the
power-on state appear. However, as a feature of this switch α $, for example, the left iil of the
decoration edge of the shorting piece a sand is flat s (I! J is made to be J, and the downward
facing 8 pieces (2) (holding part) which carries out click engagement with the right side contact
piece (16b) by the adjacent part is protrudingly formed. That is, as the reason for making the edge side of the short-circuited piece (2) into such a structure, the electric on / off is mainly
performed on the flat portion (click on the bent portion of the contact piece on the line i1
engaged SC * Fi- side by the row I1). It is to make it function as snug and (7). Therefore, despite
the fact that All is in the off state, the fold portion (17b) of the brow and the holding l! In (2), only
the curve @ (t 7a) on the other side and the flat 1BQ 9 are separated while substantially
contacting each other, and if it is turned on as shown in B, the curve portion (17b) and the
engagement SW click With the other 7 ratts saI engaged, each contact strip (4) is in close contact
with the shorting strip a (presenced) by the elasticity of both contact strips αe on its
corresponding curved portion (17a) K seat 161), (16b) are electrically conducted. In addition,
although the code | symbol +20 has shown the standup | rising piece provided in the short
circuit one side, the attachment of the base of each contact piece 118 can also be attached to
IIIIil fixed material by forming a bent piece etc. instead of a hole. .

Thus the switch a! Configured as described above! Not only can the contact / separation distance
between the contact piece QG and the short-circuit piece a be reduced, but also the self-cleaning
effect of the flat portion is large, and in the on state, the connection can be stabilized by
engagement of the contact piece and the short-circuit piece. It has the advantage of: Referring
again to FIG. 2, in the case of this example, the above-mentioned contact piece is attached to the
inner at 1 side (8), the outer tea IIK is a shorting piece (11 is attached respectively, and the relief
hole of the inner fillH formed in advance. 1i! A switch a9 is interposed using II and a recess υ on
the inner surface of the outer cylinder 11 substantially corresponding thereto. The above
describes one example of a wireless microphone to which the present invention is applied. In
short, the present invention is a slide type switch for turning on and off various electric circuits,
the juxtaposed elastic contact pieces and the corresponding shorting pieces. The unique idea is
applied to the configuration, and the effect that the present invention switch can exhibit is
already apparent from the above contents, and despite the simple combination of members,
various electronic devices such as microphones as illustrated. By attaching this to K, it is possible
to obtain superior functions as compared to conventional switches. In addition, this invention can
take various aspects other than a practical example.
