DETAILED DESCRIPTION OF THE INVENTION The invention adjusts and displays the volume of
each channel in a four channel stereo system. Yannel volume m ** concerning iut. Recently, as
shown in FIG. 1, 4f yannel stereos have been performed on 4R of the first layer J, each of which
has been subjected to Subei 1tzei, tax, sex, se41-.PHI.t2-.pi .- '2.theta.-. In this case, as shown in
FIG. 3, 4 f channel signals gxox, sa 2. sos. The signal from 104 is a variable resistor R4o1, 4ax.
The current is adjusted at 4 # J and J # J, amplified at 11601 ° 102.111: t and 8114 and added.
The output to be applied to each SVY 211.201.10: I, 1 (14) is displayed on the increase i 'i # i 01.
101 ° io J, xa 41 = 9 Ml output display 8 g 61 mg ml, 602, 804. However, in the conventional 4channel stereo, each output display @ 601, III, 102. Since σ 04 is juxtaposed in a row, when the
variable resistance @ 411, 402, 403, 404 (r) 1 ql is operated and the A- is operated, when the
variable lever is moved in any direction, which output display get, get . It is not clear whether the
display of gas and go4 changes, each speaker! 01.202.2eJ, j # J's unceasing output adjustment
was ample and sufficient, and it was not possible to enjoy -θJ1t '+' channel stereo in the 4-2small rattan. The present invention has been made in view of the above points and is by K. It is
imaginative to obtain 4f volume adjustment display ** that can easily adjust the output to each
speaker. The embodiments of the present invention will be described in detail with reference to
FIGS. 8 to 10. In the 4f panel stereo, as shown in FIG. 8, the volume of each channel is controlled

by a single operation lever 11. At the periphery of the variable resistance s12 provided so as to
interlock between layers, the output display 1j of each channel includes the axis lines of the
variable resistor elements 141, 141 and 141 ° 144 of each channel, and the output display line
of each channel Are cast so as to be substantially orthogonal or substantially parallel as indicated
by dotted lines. The output display 111J of the direction in which the control lever 11 of the
variable resistor 1112 has been moved is wk counted so as to operate. An example of the
variable resistor 11jzl is shown in FIG. That is, the case 11 is formed in a box shape of squaresquare イ ア o = o (1 in-′ ′, and the lower surface is opened.
A first lever 1-1 and a second lever 1 # 2 each formed in an arc shape on the opening side of the
case IJ and provided with a slit 181.1112 in the long rod direction are overlapped in a cross
shape, The rotational axes of the variable resistance a elements 141 ° 142. 141, 144 provided
on the inner wall of the case IJ so as to be rotatable in the orthogonal direction and provided on
the outer side wall of the case 15 at both ends of the respective levers 1gJ, 1g1. The control lever
11 is rotatably provided on the bottom surface of the case 15. The control lever 1r has a pair of
overlapping slits jlll and 182 at the intersection of each of t <−xgz and tex. It penetrates and is
provided. That is, by moving the operating lever 17 along one of the slots 97) Ill, the lever iix
pivots, and the rotary shafts of the variable resistor elements 141 and 142 provided at both ends
of the lever L12 are rotated and output It is adjusted. Similarly, by moving the operating lever 11
along the other slit lll, the lever 1 # 1 is provided at the both ends of the lever 回 -−4−-sand 6
((t). The rotation axes of the variable resistor elements 141 and 144 are rotated to adjust the
output 118. Therefore, when the variable resistance jJj as shown in FIG. 4 is used, the axes of the
variable resistor elements 141, 142, 143 ° 144 of each channel and the output display line of
the output display 11Jj are substantially orthogonal. 1 Set up. Also, another example of the
variable resistor 12 is shown in FIG. That is, the first slide variable resistance! The bulk 145 and
the ninth slide variable resistor element J4g are provided so as to be substantially orthogonal to
each other, and the control lever 171 of the slide variable resistor element JJJ of w-1 is a case of
the third slide variable resistor element 14- It is fixed to the body and constituted. That is, the
resistance value of the third slide 1 q variable resistance field element 14 # is changed by
moving the control lever 11 of the third slide 1 q variable resistance field element 14 g in the left
and right directions in the drawing. In the variable resistor element 145, the control lever 111 is
locked in the housing groove and does not move, and the resistance value does not change, while
the first variable resistance element o of the slide variable resistance element element 14σ of o
2 The operating lever 1r is moved to the upper and lower corners in the drawing, and the
operating lever 11 is locked together with the housing groove of the second slide variable
resistor element 14g to move together, and the third slide variable resistor element 14g The
resistance value of the first slide variable resistor element 145 is changed by the movement of
the operation lever 111 fixed to the position.

Therefore, variable resistance as shown in the figure below! The axis line of the variable resistor
elements 141 ° 142. 143 and 144 of each channel and the output display line of the output
display IJ are arranged substantially parallel to each other on the pedestal using 112. As
mentioned above, this invention 4 channel sound ll1l tidy display! According to (1), the output
display is disposed around the variable resistor, and the axis line of the variable resistor element
of each channel and the output display line of the output display are provided substantially
orthogonal or substantially parallel (two Therefore, the movement direction of the control lever
of the variable resistor and the output display line of the output display, which changes with the
movement of the control lever, are made to coincide with each other. 20-g-.delta.2, which is
advantageous in that the output adjustment of each channel can be easily performed.
