DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a variable resistor,
for example, a microphone connected to a microphone amplifier and an equalizer as a parlancer,
and a variable resistor sepa scene 3 f machine used for improving the night (K (K It is intended to
enhance. Fig. 1 shows the conventional one! The device is shown in the figure, the variable
resistor + 11 is provided with both 11 ec of the resistor (1 &), microphone microphone amplifier
(21 and equalizer (3) are connected to lll Q 3 respectively, microphone or other (any (Not shown)
are respectively amplified in the corresponding amplification .gamma.4f 21 131, and the fourwidth signal is amplified by the tape recorder circuit 14) or other 19U path (5) K as required. Are
formed to be combined and led out. (6) shows a slider sliding on the resistor (1a) to adjust the
output signal, and by sliding the slider 16) to the contact point or (121 or its intermediate
contact 161) , Microphone amplifier or equalization II (from 31 to the resistor (1a) without the
signal from the contact tape recorder circuit (4) or from the i-clock 7-on amplifier and equalizer

resistance 11 of the resistor (la) is not equal to the equalizer (the output impedance of 31 is
equal to that of the microphone 121), the slider (6) is at the contact point u11 or If there is a
drawback that separation with other scopes can not be obtained well, then the resistance value of
the resistor (1a) can be expressed by the equation (1) or the equalizer (from 31). The output

impedance of HqvN & low and ^ U) is not opposite to the status of the monument statement that
the output will be worn out. The present invention is intended to eliminate such drawbacks to
"IJ%." An embodiment of the present invention will be described with reference to FIGS. 2 to 4
below +21. The parts corresponding to the 11th gK will be described with the same reference
numerals. In the present invention, it comprises a resistor (1a) and a slider (6) sliding on the
resistor (IIL), and the slider (6) is a contact of the shoulder of the resistor (la) To bring the
contact point Q of the other base 4 close to ground or ground it, and close the contact point t13
of the ground, open the contact 1111 of -1 or ground it. The above description will be further
detailed with reference to FIG. 42 to FIG. FIG. 2 shows 11 views of an embodiment of the town
change resistor according to the present invention, yellow in the figure, t7 + shows a pivoting
wheel made of Ie repelling material, and this turn-axis (7) has 4 at one end. The child (7a) is
brazed and the fixed drum case 181197Q (I is freely rotatable KJ1 + 4.
In the case (8), a ring-shaped resistor CIIL cut out in part is concentrically throated, and in the
case (91 and Q [IVC is microphone amplification 1) i21 and equalizer (3) respectively] Partially
gold-cut ring-shaped connecting pieces (+ ii + f3 are concentrically attached to each other). 13)
Connect contacts 1111 (1F) to the resistor (1a) and 411, and connect the microphone cylinder
phon amplifier (2) equalizer (3) to 41 ? 1121, respectively. The contacts ?? q seconds and i19
are provided respectively. In this case, the contacts 111 and 0 are respectively in contact with
the contact piece 1e and J1! ! Keep it warm and in the opposite direction of one turn of the cuff)
and KrL together! ! ???? The contact point 11 II is equal to micro 7 o / amplifier 421
respectively! ! I am vague to 131. In @ (), in each case x + s + 1911101, a slider (61) (last) is
provided which is longer than the conductive one extending in the first direction. When the shaft
(7) is turned, the slider (6) и an looser corresponds to the corresponding resistor (IIL), the
connecting piece usus, and the resistor a and the pseudo connected piece G51tllK & It is possible
to form a sliding contact on the contact point OD + 121.071 (18% 09). FIG. 4 shows a circuit
diagram of the device of the present invention, and the slider (6) Q3c # is respectively connected
to the tape recorder 1 to 1M + 41, the microphone expander (21 and the equalizer (3)). Since the
present invention is configured as described above, if the knob (71L) is moved in the direction of
the arrow tol in FIG. 2, the slider + 61121 + 24) will be arrow a in FIG. At this time, the slider and
key point 0 are in contact with each other without the resistor (1a), and the microphone amplifier
(2) and the tape recorder circuit (4) slide the slider 16). Through и и и и y 43 Figure B, OK, # I
Kanko (() is the connection piece + 161 to 41! It is possible to ground the signal from the
equalizer (3) in contact with the grounded and grounded contact point fi9. Also, the signal from
the microphone amplifier (2) through the slider 7 can be blocked. Contrary to the above, when
pulling the glass (7a) in the reverse arrow a direction K), the slider 161C! ICl4) is interlocked
with the shaft ()) K and rotated in the direction of the arrow a in FIG. 3A, B, OK, at this time, (the
facet + 61 and the contact u3 are intervened by the resistor (1a) Without confronting, equalizer
(4) and Chipregorda (aIlll !! B) and the slider + 61 [following the flat, and the slider 1 is abducted
from the connection piece uS and the contact point is running contact!

Microphone amplification in close proximity to one arm! The signal from +21 can be grounded.
At this time, equalization 4 (the signal from 3I can be blocked via the slider). If the slider (6) is
turned to the middle contact (C) position by recommending the pin 5I or the insulator (the a) to
lol, the slider (6 :,. The signals from the microphone amplifier (2) and the equalizer (3) are
respectively supplied to the resistors (through the tape recorder circuit 141K11! Rukoto can.
Since the present invention is as described above, the present invention 1! If: According to this,
by rotating the slider + 81 to the contact point (one point turns to the position of +12, the
microphone amplifier (2) stores the signal from the equalization 4 (3) against each other The
tape recorder can be sent to a single tape recorder, and a good separation can be obtained. In
addition, in the case of the middle saddle point (c> Km, the slider + 61 K! Since I # is grounded
and Rs??II (II 71 floats), the tape recorder circuit (4) has a mixed output иии from the double
amplification 6121131. In short, the resistance capacity of the variable resistor is simple and
excellent because it can be distributed only in the amount necessary to obtain a single output.
The case + 81 + 91 Q и shown in FIG. 2 is not limited to the arrangement of 9 necessarily and 1
case separately, and the case may be integrally formed. 61 @ 5 Fig. 6 shows another embodiment
of the device of the present invention, and the parts corresponding to Figs. 1 to 4 will be
described with the same reference numerals. In FIG. 5, a cam 3? having a projection (311L) at
the free end of the shaft (7) through which the drum case (8) is inserted is internally fixed, and
may be grounded to correspond to the cam 31). A switcher switch with a contact piece (321L) is
provided. 6A-8. 0 respectively show the connection circuit diagram of t45, and the town aS piece
(321L) is the axis (7) in the direction of the arrow a or the direction of the arrow a in FIG.
Therefore, in the direction of the arrow a or the direction of the arrow a of the cam 6. The point
(32 in FIG. 6A) or contact point (FIG. 6G in FIG. 6G) is displayed on the point (32b) by gl motion,
or the middle ill point 0> position (the state in 61B). ), And connect the slider (6) to the contact
+12 or the contact U ? ? to ground the output of the other basket, and when the slider +61 is
the middle contact CC ') K The movable armature (32 to 32 can be floated to combine the
outputs of both amplifiers f2 + + 31 with one another, and the output can be continued to the
tape recorder circuit f41 K11. In this case, the cam convex @ (31 to 1 town holding the housing
wI contact piece (321L) is rotated by 1 and the movable contact piece (32 to the contact point uD
or the hard point 71Q3 is inserted equally with K @ 171K click mechanism b can be provided.
Also in the embodiment shown in FIG. A brief explanation t 41 figure of the garden side is one of
