DESCRIPTION JPS516901
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a system diagram showing an embodiment of
the present invention. I selection switch 13, ..... secondary selection switch, 14 ..... secondary
regeneration system 1-1 51 51-6901 (2) Correction ? 49.8. 10 Correct the drawing as follows.
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the improvement
of a signal reproduction apparatus for reproducing an arbitrarily selected signal from a plurality
of signals. For example, there is a stereo reproduction apparatus as a conventional apparatus of
this kind, but there is no means for confirming other signals except for the signal being
reproduced, and it is inconvenient to use. Zero-train J, i, was made in view of such actual
situation, the purpose to be born is a simple configuration that can be selected simultaneously to
play simultaneously the signal during playback as well as other -1 = signal The present invention
is to provide a signal reproduction apparatus for Other objects or effects will be apparent from
the following description. Therefore, the gist of the present invention for achieving the above
object is a signal group, a main reproduction system, a main selection switch for selecting an
arbitrary signal from the signal group and inputting it to the main reproduction system, and the
main reproduction system A signal reproducing apparatus comprising: an auxiliary reproduction
system independent of the main selection switch; and an auxiliary selection switch independent
from the main selection switch and selecting an arbitrary signal from the signal group and
inputting the selected signal to the auxiliary reproduction system. . Next, the present invention
will be specifically described based on an embodiment shown in the drawings. In the figure, a
plurality of signals el + e2 ии! Of the signal group e! The signals -11j12 ... 1fl to which +1 is
respectively applied are selectively connected via the main selection switch 5 to the amplifier 40
input terminal which constitutes the main reproduction yarn 3 together with the amplifier 2. The
output terminal of the amplifier 4 is connected to the complex terminal 6 and connected to the
amplifier 20 input terminal via the changeover switch 7. The switch T has two fixed contacts
C15C2, one fixed contact C1 being connected to the output terminal of the amplifier 4 and the

other fixed contact C2 being connected to the monitor terminal 8. Further, the output terminal of
the amplifier 2 is connected to the speaker IOK via the switch 9t-and is connected to the first
contact dIK of the earphone jack 11 as well. Reference numeral 12 denotes a gain adjuster of the
main reproduction system 3. Further, the signal lines 11 * 12, fists, and 1n are selectively Km
selected to the input terminal of the amplifier 15 constituting the sub reproduction system 14 via
the sub selection switch 13 which can be operated independently of the main selection switch 5
Ru. The output terminal of the amplifier 15 is connected to the second fixed contact d2 of the
earphone jack 11 and connected to the speaker 11 Km via the switch 16 and connected to the
second fixed contact d2. Reference numeral 18 denotes a gain adjuster of the sub reproduction
system 14. Further, a daughter tape recorder 190 input terminal is connected to the abovementioned metering terminal 6, and a monitor signal outputted from the tape recorder 1 s is
connected to the monitor terminal 8.
3- However, when the changeover switch 7 inserted in the main reproduction system 3 is
switched to the (fixed) constant contact cl @@, the signal selected by the main selection switch 5,
for example, el is reproduced by the main reproduction system 3 Be done. At the same time, the
signal e1 is recorded by the tape recorder 11 connected to the recording terminal 6. When the
changeover switch 1 is switched to the fixed contact C2 side, the monitor signal (ie, el) output
from the tape recorder 11 is input to the amplifier 2 and reproduced. On the other hand, in any
of the above-mentioned cases 11, the signal selected by the hard selection switch 13, for
example, el is reproduced by the auxiliary reproduction system. That is, the secondary
reproduction system 14 can select and reproduce any signal el + e2... EQ of the signal group e
without affecting the main reproduction system 2. Therefore, it is extremely convenient because
the cough signal e1 and other signals e2 + e5... E6 can be reproduced arbitrarily while the signal
e.g. This is advantageous when the content of each signal e1 и conflict и eQ is K-4-advantageous,
and a signal different from the main regeneration system 3 can be reproduced 14 and the use
range of the signal regeneration device is expanded 3 and the main reproduction system 3 and
the sub reproduction system 14 are independent of each other. For example, when confirming
the contents of each signal el + e2. It is possible to reduce the amount by 18 so that the
reproduction sound from the speaker 1T of the secondary reproduction system 14 does not
disturb the reproduction sound from the speaker 10 of the main reproduction system 3. Further,
in the present embodiment, the changeover switch T of the main reproduction system 3 is
switched to the fixed contact C2 side, and the one main selection switch 5 and the one selection
switch 13 are connected to the same signal line 11 for example. If a binaural receiver is inserted
in the tape recorder 1g, the monitor signal of the tape recorder 1g, ie, the signal e1 recorded and
reproduced by the tape recorder 1s, is compared with the signal e1 directly input to the amplifier
15 to compare the tape recorder 19 It can be done. As apparent from the above description,
according to the signal reproducing apparatus of the fifth aspect of the present invention, it is
possible to arbitrarily reproduce the signals of the signal group by II reproduction independently
of the main reproduction system. Since the main reproduction system and the secondary
09-05-2019

reproduction system are provided independently of each other, the gain and the like of each
reproduction system can be arbitrarily set according to the purpose of use. It is also possible to
monitor the main reproduction system by means of the secondary reproduction system. The
present invention is not limited to the configuration of the above embodiment, but a wide range
of modifications may be permitted. For example, the main reproduction system 31 It is possible
to apply the present invention to a stereo reproduction apparatus or the like by arranging two in
parallel and forming the main selection switch 5 as a two-circuit type switch.
