[Detailed description of the invention] The present invention relates to a wireless wireless
microphone device used with a radio with a wireless device, etc., configured to use a power
source in the device main body with a simple configuration and selectively use it. The purpose is
to make it possible to use the power source effectively. This type of wireless mittalophone wl
commonly used in Nono 2 is configured as shown in FIG. That is, in the second tIII, 14 is a
microphone, and the microphone 14 & l: is configured so that a predetermined power supply
voltage is always supplied from the battery 16 in the apparatus main body. The main body of the
apparatus has a connection terminal 18 connected to the tape recorder and an output circuit
'841' from the microphone fourteen 14. When the connection terminal 18 is connected to the
tape recorder KIIM, the output from the microphone 14 is provided. Is supplied to the tape
recorder via the connection terminal 18t-and the connection terminal 18 is disconnected from
the tape recorder-The output from the microphone 14 is transmitted to the transmission circuit
16 via the connection terminal 111 when the connection terminal 18 is disconnected from the
tape recorder. It is configured to be radiated as radio waves from the antenna. By the way, in this
wireless microphone device, the battery 16 in the main body of the device is constantly supplied
with power from the side 16 via the switch 17t- separately provided on the transmitting circuit
18 and the battery 16 in the transmitter circuit 18 separately. If the switch 17 is turned on and
connected while being connected to the 1st tape recorder, the output from the microphone 14 is
supplied to the tape recorder 9 through the connection terminal 18. Nevertheless, the transmitter

circuit 16 was still in a state of operation, and extremely inconvenient situations such as the
emission of an unintense radio wave from the antenna occurred. On the other hand, as shown in
the IIs diagram, it is also known that the continuous terminal 18 is structured such that the tape
recorder supplies power to the microphone 14 in conjunction with the digital decoder Kli
Separately, the connection terminal 19 dedicated to the power supply is used and 1 '° 1 · 12 ′
′ ′ ′ ′ ′ ′ ′ ′ tOmlll I4 + −zeo * hK. Irrespectively, the transmission path 18 is
configured to be able to supply power to the white image from the battery 16 in the main body
of the apparatus by the switch 17, so that it is the same as the conventional example shown in
FIG. The fault vvtit. 1あつぇ。 The present invention eliminates the above-mentioned
conventional drawbacks. When atII is connected to a tape terminal recorder, power is supplied
from a microphone and a feed path, respectively, and the battery is supplied from the device. Are
automatically configured to be disconnected from the microphone and the transmission circuit,
and the wireless microphone p-phone of the present invention will be described below with
reference to the drawings of one embodiment.
In the figure, 1 is a two-wire i microphone, and the lead wire of To9 is grounded, and the other
movable contact piece 2 'JIK of the connection terminal 2 connected to the other lead wire tape 3
is connected o2t It is a connection terminal connected to the tape recorder 8 and, in addition to
the above-mentioned contact piece 2a, it is touching at all times as described above. ! A fixed
contact piece 2b of 1, a second movable contact piece 2d, and a fixed contact piece 2 @ of the ls
2 constantly contacting the second movable contact piece 2d and an earth contact piece 2. The
second fixed contact piece 20 and the movable contact piece 2d of the second rod 2 are
connected to the power terminal of the transmission circuit 7 and the battery 6, respectively.
Connected to the positive terminal of the And further, it is connected to the negative terminal of
the earth contact piece 2 and the turtle pond s, and is grounded 0 to 8 are connected at the
output end KW of the transmission 1N− path 7) 1 antenna, and this antenna 8 and the
transmission circuit 7 An apparatus body 12 is configured by the microphone 1, the connection
electron 2, the resistor 4, the condenser t 3, and the IE 麹 6. A tape recorder 1a is provided with
a trailing terminal 9 connected to the connection terminal 2 of the apparatus body 12. The
subsequent terminal e is knocked KMffc and is provided with a ground contact piece 9b and an
input contact piece 9a. Then, when the subsequent terminal S is inserted into the connection
terminal 2 of the apparatus body 12, the ground contact piece 9b contacts the ground contact
piece 2 and the input cylindrical piece Glali first movable contact piece 2aK "! 11 is configured to
touch. At this time, at the same time, the first to twentieth movable contact pieces 3a and ad are
simultaneously driven. Fixed contact pieces 2b and 2d of @ 2. It is comprised so that it may space
apart II. Note that 1 o is a resistor connected between the input contact piece 9 a of the
connection terminal 9 and the ◆ j 3 J II l, which is coupled to 11; In the above embodiment, the
connection terminal 2 of the device main body 120 is a tipple; In the case of a dovetailed house,
as described above, the contact piece 2a of the connection electron 2 is in contact with the
movable contact piece 2a of the 1st solid piece i1 contact piece 2b) and the twentieth town
01-05-2019
2
connection piece 2d is The second stationary contact piece 2cK is in contact. Therefore, the
power from the battery 6 is applied to the transmission circuit via the second movable contact
piece 2d and the second fixed contact piece 2c, and at the same time, the resistance 4 & the first
fixed contact piece 2b, the first movable contact It is applied to the microphone 1 through the
piece 2 at. And the output from microphos / 1 is 5! It is applied to the transmission circuit 7 via
the movable contact piece 2a of 1, the fixed contact piece 2b of the weir 1, and the capacitor st,
and is transmitted from the antenna 8 as a radio wave.
The case in which the Ki device main body 12C1 alarm terminal 2 is connected to the tape record
r1so * ladder 9 will be described. In this case, as described above, the input contact piece 9a and
the grounding piece 9b of the connection terminal 9 are in contact with the first movable contact
piece 2a and the ground contact piece 2 of the connection terminal 2, respectively. The contacts
sia and ad are spaced apart from the fixed contacts ah and 2o, respectively, and the charge I from
the battery 6! Is not supplied to the book, the microphone 1 or the transmission circuit 7. Then,
in this case, the IC only supplies the microphone power from the tape recorder 3 to the
microphone 1 via the フ resistor 1o, the input contact piece 9a and the movable contact piece 2a.
The output from 1 is supplied to the input terminal of the tape recorder 130 via the movable
contact 2a, the manual contact 9m, and the capacitor 1. As described above, according to the
above embodiment, one charged body 12 is connected to the digital recorder 13Vc, and in this
case, the battery 6 in the device body 12 is a book that can not be bagged at all, and the
transmission circuit is also carelessly There is no possibility of becoming active. Therefore,
according to the above-mentioned embodiment, the power supply a6 can be effectively activated
and used, and the life can be extended. ! Radio waves and is extremely effective. Book 8j! As is
apparent from the above embodiment, when the connection terminal of the apparatus main body
is connected to the tape recorder, the apparatus internal O battery tiI is configured to be
dynamically set to the non-use 11 and the h9 electricity is -V * It can be used for careless
operation of the transmission circuit and unnecessary radio waves are emitted = tvht is also
advantageous O is also 0I 41. ,. □ Fig. 2 shows an electrical diagram M, Fig. 2 and Fig. 3 of an
embodiment of the wireless microphone am of the 111tj draft of the present invention.
