DETAILED DESCRIPTION OF THE INVENTION The present invention is a television ') II / f voice
multiplex 1d set-up device (part 2). General telepin 11) voice multi-electric reception-as shown in
Fig. 1 Telepino 1 audio multi-tone signal decoder + 11 and mode indicator at the time of double
electric voice broadcast reception-"Manual manual," 2) and the first channel comprising the 17th
speaker (3) and the @ 1 speaker i4) Y, the second channel and the ring-C comprising the w42
amplifier (5) and the second speaker (6) The lift table manual switch (21 ?: 4 children (7)
connected to 2nd audio terminal in lNd 1 is connected to 3 and the valley speaker! Connect the
main channel signal from 4 ++ 61 to the terminal (8), and the sub-channel signal from each
speaker, and the two terminals (9 (when connected to each speaker simultaneously apply the
respective channel After being able to do it 1: Because the different information is uttered from
each speaker via i set in the mode described, it becomes unheard of. Therefore, in this case, C2
changes the setting to another mode, or operates the 1f phone (not shown) to operate instead of
the first or second speaker: f ring groove 7i Why one yahon? In this mode, each channel signal of
the master signal can be set individually (in two modes (IT, or a manual switch is connected to
another mode tie terminal (7: or (8).) Originally, when using earphones individually (: receive,
there is an X point where the same signal as the voicing information from the speaker not using
all the earphones is received regardless of whether it is desired, this Kokushi is headphones By
attaching 4 rad-phone sockets to the plug's plug-in jack vfFgy-r, main and sub-control signals are
required when using headphones regardless of the setting position of the mode command switch
for dual audio broadcast reception It is possible to receive fgT individually and try to give 16
machines. Next, Fig. 2 shows an embodiment according to the present invention (Fig. 2: Based on
the explanation is the telephonic voice multiple defect decoder, this is an input terminal ul for
introducing a television ays voice multi event signal, and two sources The first and second output
terminals 112) for respectively deriving the output signals of (13), and further, the first and
second signals for designating the signal morton from the first and second output terminals
112113 at the time of double audio broadcasting reception 1g. The second single terminal
t1411M and a lie ° C 俵 this 俵 M! Reference numeral 1101 designates an output signal
corresponding to each input mode as shown in the chart of FIG.
The $ 2 control terminal U # (2) is invalidated at the time of monofull or stereo reception, and at
the time of full-duplex broadcast reception (= is set to each overhead mode. Then, according to
the mode, each sub channel signal (equal (87%) is configured to be derived from the output
terminal. In addition, there are 5 reviews of Ryoto Yodo of this recovery unit (in the case of 2 TV
27% # J1 (1975), pages 51 to 42, 1% semiconductor circuit for receiving TV audio multitelevision broadcasting) I would like to refer to the paper entitled "Seven insults" and I will skip
the arms because it is out of the point of uninvention, (old +1711 is the head ho / plug (gangbo
omitted) The first and second hit-phone sogets which can be removed, and each of the sink
contacts is connected to the movable contact piece when the p] Ill contact piece C 1 is attached
to the movable contact piece. Fixed contacts; Wis. 1.21+ and 1st, and further 5th Wi, points
(241A). C: A circuit for transmitting a signal from the first output terminal d to the first slider
example via the first antenna t 271 is a decoder when the headphone plug is not attached This
circuit is a circuit for transmitting the signal from the 10 second output terminal L13 to the
second speaker 311 through the 5J connection single beat of the first head phone 7e d61 and
the wL1 fixed contact 1 and (2 1 i R 2 amplifier (lst) amplifier) 1 . (6) When not using the
headphone plug, connect the first control terminal u4 of the unit 110+ to the first fixed contact
of the 12-head phone socket 1171) to the movable contact piece QI'4: Is a mode command
switch for selecting the number of tracks or t as shown in the figure, and the grounding
operation by this switch is invalidated by the device of the headphone plug to this second
headphone + 17). -The signal from the -2 output terminal U of -V wide headphone plug deviceYjiE1 The movable contact piece (2) of the headphone socket stop, the second solid contact color,
and further the 37 / b · · · resistance- It is a circuit for transmitting to the fifth contact point (-) of
this first head phone socket through the time of operation of this transmission circuit (2 is
decoded! The signal from the second output terminal t13 of fF yell! I27 / PlAl2 is not transmitted
(two configurations). (Solving) is a circuit that connects the head office 7 flag Q] table temporary
@ at the county's county's county's district 2 system via the second headphone socket surface,
and C) at the time of operation of the circuit Since the movable contact piece 11 field of the
headphone socket surface is switched from the first fixed contact point 呟) to the second fixed
contact point −, the decoder U · U) i14iThJth7 + il ui) @ 1! !
Function to inhibit grounding by the dm contact point 211 The amplification factor 7 of the @ 2

compared enough (2 It can be increased by 6 degrees, or it can be resistance l! ilv gate phone
output! Figure 4 is a chart to explain the operation of this receiver, and it is L1 from the 1st and
2nd speakers at the time of non-gii of 1-head phone and in stereo or monaural broadcast text gi.
Hill or monosil can be received, and at the time of 2 t-V * broadcast reception, depending on
which switch is selected to terminal u4 or t141, "c" from the first and second speakers as main or
as shown The secondary channel-6% LMI (81 w can be avowed. But each channel / 18-Ik
'individually annoyed and uncomfortable? Then, when the headphone is released to public, the
first and second limit terminals 114uhl of the decoder α · are always high and low combinations,
so the main channel signal from the first speaker is In addition, people can be derived from the
headphones to the sub-channels respectively. And if you wear a headphone plug into this 8operation headphone socket (regardless of the setting position of the switch, it is guaranteed. As
described above, in the receiver according to the present invention, in order to be able to
simultaneously receive the main and sub channel signals at the time of double broadcast
reception, it is necessary to attach a headphone plug to the headphone socket. There is no risk
that different types of information will be emitted from the speakers and may cause discomfort
to the listener, and the two types of headphone plugs must be Wtfj. It is possible to enjoy
information and improve usability.
