Attorney Nakao Toshio 1 person Detailed description of the invention The present invention is
for volume adjustment and balance adjustment used in 4-channel stereo device And provides an
excellent volume device with a simple configuration. Hereinafter, the volume apparatus of the
present invention will be described with reference to the drawings of one embodiment. In the
figure, 1 is a bearing device made of a steel ball or the like attached to the center portion of the
front plate 1a of the case 1, and 3 and 4 are side plates 1bt1c whose both ends are opposed to
each other in the case 1 shaft 5.6. The semicircular arc-shaped rotating plate held by the above,
7 [111 111] 8 is a long hole formed in the central part of the above-mentioned rotating plates 3
and 4 in the longitudinal direction, 9, 10 and 11 A resistor mounted on the inner surface of the
moving plate 3, 4 in a portion separated by θ and a long hole 7, 8, 13 is pivotally mounted so
that the central portion can be three-dimensionally pivoted by the bearing device 2 Part is
inserted in both long holes 7 and 8 of the rotation plates 3 and 4, 14 is an operation knob
attached to the other end of the operation shaft 13, 15, 16, 17 ° 18 is the above operation A
rotary type volume adjusting variable resistor whose axis of rotation is the axis 13, 19.20 turns
around the outer periphery of the variable resistor 18. A stopper for preventing variable resistor
rotation, which is provided protruding on the side of the plates 3 and 4 and whose tip is inserted
into the long hole 7 of the mounting plate 3, 21 is a rotating plate 3 or 4 of the variable resistor
18. Sliding terminal mounting plates 23, 24 and 25, 26 attached to the side through the spacer
22 are sliding terminals sliding on the resistances 9 and 10 ° L 12, respectively. Incidentally,
the rotary plates 3 and 4 are mounted in directions orthogonal to each other, and the resistor 9
and 10 ° L 12 mounted on the rotary plate 3.4 and the slide terminals 23 mounted on the slide
terminal mounting plate 21 The variable resistors for balance adjustment interlocking with each
other are configured. In the above embodiment, when the operation knob 14 is turned about the

bearing device 2 in the directions of arrows A, B, C, D, the tip of the operation shaft 13 is in the
direction of the arrow ports a, b and c. Similarly, the sliding terminals 23 ° 24. 25 and 26 for
transition also shift, so that the resistors 9 and 10. The individual variable resistors formed
between L12 and the sliding terminals 23.degree. 24. 25 and 26 are similarly driven in
conjunction.
When the operation knob 14 is rotated in the directions of the arrows E and F, the four variable
resistors 15 and 16 ° 17.18 are simultaneously driven in the same direction. Therefore, if the
volume device of the above embodiment is connected as shown in FIG. 5 and used in a fourchannel stereo device, the variable resistor 15.16.17.18 [111111] EndPage: 1 is a variable
resistor for adjusting the entire volume. And the resistor 910. The variable resistor formed of the
L12 and the sliding terminals 23, 24, 25 becomes a variable resistor for balancing left, right,
front and back. In the present invention, two pivoting plates having long holes in the longitudinal
direction at the central portion formed in an arc shape as described above are disposed so as to
be orthogonal to each other, and both ends thereof are respectively opposed to each other in the
case The operating shaft, which is pivotally attached to the face plate and whose central portion
is pivotally attached to the front plate of the case so as to be able to rotate three-dimensionally, is
inserted into the long holes of the two pivoting plates The rotating plate is configured to be
rotated in conjunction with each other, and the balance adjusting variable resistor interlocked
with it is driven by the rotation of the rotating plate, and the case of the operation shaft and the
rotating plate And a rotary variable resistor disposed between them, and configured to be able to
drive the rotary variable resistor by turning the operation shaft, and the rotary variable resistor is
turned with the case. Because it is installed between the plates, the whole size is not the abovementioned rotary variable resistor If the are exactly the same, will be the substantial size of the
entire, Moreover, it is possible to perform many operations in one operation knob, the operation
itself is extremely advantageous. In particular, when the volume device of the present invention is
used in a 4-channel stereo device, the volume device can be used as a volume device for volume
adjustment and balance adjustment, its operation is easy, and the position of the operation knob
is directly balanced. It has many advantages such as displaying the status of In the embodiment,
the case where the resistor is directly attached to the rotating plate has been described, but the
same applies to the case where a rotary variable resistor separately formed on the pivot shaft of
the rotating plate is attached.
