Sometimes, sometimes it is convenient to head down if you can perform 150 plating such as
making the rear right signal smaller at the same time and making the left front signal and right
front signal all thick at the same time and making the left rear signal and right rear signal smaller
simultaneously. is there. For such control, there is proposed a multi-axis simultaneous @ bag
forming RJ of a variable resistor. In this conventional displacement rod, the periphery of the yarn
is bent into a box shape, and variable resistors are attached to the opposite surfaces of the box. It
adjusts the resistance of the variable resistor and that both ends of the semi-circular interlocking
plate adjustment of the variable resistor. The adjustment lever is inserted into the slot along the
longitudinal direction of the interlocking plate, and the plurality of variable resistors are
simultaneously adjusted by rotating the lever. In this device, a pair of variable resistors C,--,-. It is
mounted on a non-planar and parallel surface, and has a three-dimensional structure, making the
overall shape thicker. Furthermore, the pivoting range of the lever is 90 degrees in terms of
physicality, but it is actually about vcu'to ~ 80 degrees, whereas the variable resistor is generally
adjustable by about 290 degrees. There are 20 (2) A ('* At 0 to n. Therefore, it is necessary to use
the variable resistor L7 effectively, and in order to obtain a predetermined volume range with a
small adjustment range, it is necessary to sharply change the resistance value and one change

characteristic to the rotation of the adjustment shaft of the variable resistor. Yes, so it will be
difficult to adjust. Nine levers are in the arc-like interlocking plate. When it is at the middle
position It L, the torque required to turn the interlocking plate is minimized, and as the lever
approaches the end of the interlocking plate, the torque required to rotate the union W gold
increases. As the torque required for the rotation of the adjustment lever is from the pivot
position fjlVC of the lever. The purpose of this device was flat: m5t, so it can be small, and it can
be pivoted to the full extent of the adjustment shaft of the variable resistor, and the purpose of
this invention is flat, which can also be adjusted The relative g: i, .l.l.l. ((The required torque is to
provide a multi-axis simultaneous adjustment device W for each variable resistor, which is
uniform in each part). Hereinafter, the present invention will be described with reference to the
drawings in order to provide a multi-axis simultaneous adjustment device according to the
present invention.
The single substrate is shown in the figure and on the substrate 1. The two racks 2 and 3 are
disposed so as to slide in the direction of extension 1 substantially orthogonal to each other.
Racks 2 and 3 ') Each central part is cut off from one side, and the thickness is cut in half at both
ends, and two racks are cut off. The surface not to be removed is on the side of substrate 1 The
rack 3 ', which has been cut off, faces the board 1 @ ic. Further, teeth 2a, 2b, 3a, 3b are
respectively formed on the opposite side surfaces of both ends of the rack 2 ° 3. The teeth 2a,
3a and the teeth 2b, 3b, respectively, Pinions 4a, 4b + 5a, 5b meshed with the respective teeth
2a12b, 3aI3b of the racks 2 and 3 are provided so as to face each other. A variable resistor 6a,
such that these pinions are respectively mounted on the adjustment shaft bar. I6I '), 7a, 7b are
attached to the substrate 1, respectively, ie the body of the variable resistors 6a, 6b-7a, 7b is
attached to the substrate l on the opposite side to its -yh rack 2.3, these variable machines

1-41 R are projected to the rack Q 1 of the substrate 1. These protrude nine shafts 8a, 3b, 9a, 9b
on the pinion 4a. 4b-5aI5b is fixed respectively. Each shaft 8.9 protrudes further than the pinion
4.5, and the limiting plate 10 is fixed to each protruding end. The racks 2 and 3 are restricted by
the restriction plate 10 so that they do not move from the substrate l in the direction
perpendicular to the beams. Further, guide pieces 11 in contact with the side surfaces of the
racks 2 and 3 are respectively erected on the substrate 1 on the opposite sides of the pinions 4a
+ 4bs 5a + 5b. Each of the two racks 2 and 3'r) is guided so as to be moved in the direction of
extension, and each of the slots 12 'and 13' is cut from one side. The center hole 14 is formed
relatively large at the center of the substrate 11 '+ with respect to the mounting positions of the
variable resistors 6a + 6b and 7a, 7b. The lever 15 is loosely inserted into the groove holes 12
and 13 and the central hole 14. A worm body 16 is mounted through the variable resistor side of
the lever 15 so that the through end of the lever stands vertically on the fixed portion 17. The
substrate l is spherically supported against the ball 16K (5) 49-41229-06. For this reason, three
or more arms 18 are erected on the variable resistor side of the substrate 11 with the center hole
14 at the center, the ends of the arms 18 are bent inward, and the bearing portion along the

upper half of the ball 16 In this bent position, the lower half of the ball 16 is fitted with a dish 20
which is held in place and the arm 18f1r is held by the ball 16 so that the substrate 1 can be
rotated.
A cover 21 covering the substrate l, the rack 2.3, the variable resistors 5a, 5b + 7a + 7b, etc. is
attached to the substrate l. An indicator lamp 22 is attached to the end of the lever 15 which
projects into the rack lb'i within the cover 21. The cover 21 is made transparent so that the
position of the lamp 22 can be viewed from the outside at least at least within the substrate 1
and the lever 15 and the pivoting range. Or it is made translucent 15 bodies. When the cover 21
is pivoted, the portion facing the indicator lamp 22 may be shaped to move closer to the lamp. In
the above configuration, for example, the variable resistors 6a and 7a are four channel stereo left
front signal and right front signal, respectively. 49-12229-07 (6) -1'jK volume adjustment,
variable resistors 6b and 7bl are volume adjustments for the right rear signal and left rear signal
respectively, and in the figure, the volume of the variable resistors 4a and 4bu is around the right
, And the variable resistors 5a and 5b are connected so as to increase in volume by 5 around the
right. If the user touches the cover 21 and turns it to the left in the figure, for example, the lever
15 slides on the substrate 1 relative to the rack 2 relatively to the right. Therefore, the variable
resistor 6a turns to the right and the volume is small, and the variable resistor W6b turns to the
left and the volume increases. This one. . At 1 o'clock lever 15 along the same, along the line #
13, the rack 3 is stopped without sliding. When the cover 21 is pivoted in the front-rear direction
in the drawing, only the rack 3 slides against the substrate IK, and only the variable resistors 5a
and 5b are adjusted. When the cover 521 is rotated in an appropriate direction, the rack 2.3
slides according to the component force of the racks 2 and 3 in that direction, and the variable
resistors 6a, 6b, 7a + 7b are moved according to the slide. Each “FiI @ i” +, as described above,
according to the device according to the present invention, a plurality of variable resistors can be
simultaneously controlled at an arbitrary 10 ratio by turning the cover 2149-41229-08 and K. In
this apparatus, since the variable resistors 6f, 6b, 7m and 7b are mounted on one plane of the
substrate l, they are configured in a plane and miniaturized. Relative to lever 15 and substrate l.
The torque is fixed between the rack and the central axis of the pinion meshing with the rack,
and does not change depending on the relative rotational angle position, because the rotary shaft
rotates the adjustment shaft of each resistor. Control is possible with the same torque over the
entire adjustment range, making it easy to adjust. 10 Furthermore, it is possible to change the
rotation angle of vI4 axis alignment of the variable resistor with respect to rack tooth and pinion
diameter and V (from the rack's jP + 1-movement length, thus adjusting the variable resistor over
a wide angle It is possible to do so, and the volume adjustment book becomes so easy.
The same as the rack 2.3 when the pinions are engaged with the two side surfaces of one twotrack as described above and one pinion is positioned at one angular internal pressure formed by
two racks. Parts can be used. Fixing the lever 15 in the above. Fix the substrate 1 without 1B +

49-41229-09 and adjust the lever 15 by turning. It will also be tidying up. ″! One of the
variable resistors 6a and 6b and one of the variable resistors 7a and 7b may be omitted.
