A plurality of scales arranged in a position facing the part and formed radially so as to overlap with the operation protrusion, There is no need to prepare an operation knob, and a common operation knob is simply installed above the color-coded body for each function, which prevents incorrectly attaching operation knobs of different colors and allows the operation knob to be slim. It has an excellent design, and the protrusion on the operating section improves operability.

Embodiment FIGS. 1 and 2 show the operation knob structure according to the present invention. In both figures, a large number of operation knobs 2 are arranged on the front panel 1 of the mixer.

As shown in FIGS. 1 and 2, the front panel 1 is provided with a plurality of openings 1a at predetermined intervals. Further, a large number of volume bodies 3 for each channel (four channels in this embodiment) are arranged on the lower side of the front panel 1, and each volume body 3 is attached to the substrate 4 so as to face each opening 1a. installed. In addition, when operating each volume body 3, use the operation knob 2 attached to the shaft 5.
Rotate the top surface 6 with your fingertips.

Each operating knob 2 is color-coded according to function to prevent erroneous operation. In addition, the first row of operation knobs 2a ₁
~2a ₄ is the TRIM knob that is operated so that the input signal level is at the optimal level.
The second row of operation knobs 2b ₁ to 2b ₄ and the third row of operation knobs 2c ₁ to 2c ₄ are EQs for boosting (enhancing) or cutting (attenuating) at 100Hz to 10kHz.
These are the HIGH and EQ LOW (equalizer adjustment) knobs.

Further, the operation knobs 2d ₁ to 2d ₄ in the fourth row are EFFECT knobs for adjusting the input/output level of an externally connected effector (echo, etc.). The operation knobs 2e ₁ to 2e ₄ in the fifth row are PAN knobs that distribute input signals to left and right buses (BUSS).

Furthermore, on the right side of front panel 1, you can adjust the output level of the synchronization signal recorded on the tape.
Adjust operation knob 2f as SYNCOUT knob and headphone monitor output level
Operation knob 2g as a PHONES knob,
PHONES monitor destination conversion knob ((REMIX, MONITOR, EFFECT switching knob)
An operation knob 2h as an EFFECT MASTER knob, an operation knob 2i as an EFFECT MASTER knob, and an operation knob 2j as an EFFECT RETURN knob for switching input/output with the EFFECTOR are provided.

Reference numeral 7 denotes a scale plate, which is fixed to the lower surface of the front panel 1 by adhesive or the like. Red colored bodies 8a are formed on the scale plate 7 at positions corresponding to the first row of operation knobs 2a ₁ to 2a ₄ by, for example, screen printing or offset printing. Also, on the scale plate 7,
Similarly to the above, the second row of operation knobs 2b ₁ to 2b ₄ and 3
Orange colored bodies 8b and 8c are printed at positions corresponding to the operation knobs 2c ₁ to 2c ₄ in the row. Also, the fourth

d, 8e are printed.

Further, colored bodies 8f to 8j of blue, red, red, green, and red are printed at positions on the scale plate 7 corresponding to the operation switches 2f to 2j, respectively.

Further, on the colored bodies 8a to 8j facing each opening 1a of the front panel 1, there are scales 9 for each predetermined angle.
are printed with black lines or the like radially from the hole 7a of the scale plate 7 through which the shaft 5 is inserted.

As shown in FIGS. 3 and 4 A, B, and C, the operating knob 2 has a transparent part 10 as an operating part molded into a ring shape from a transparent material such as synthetic resin.
and an opaque portion 11 made of an opaque material such as black. The transparent part 10 has a step part 10b inside a ring-shaped peripheral part 10a, and a protrusion 10c projects from the peripheral part 10a. In addition, a central hole 10d is provided in the center of the stepped portion 10b.
is drilled.

The opaque part 11 has a flange part 11a that fits into the stepped part 10b of the transparent part 10, and a cylindrical part 11b that passes through the central hole 10d. Further, the cylindrical portion 11b is provided with a fitting hole 11c having a shape corresponding to the cross-sectional shape of the shaft 5 of the volume body 3. Moreover, the cylindrical part 1
1b is provided with a slit 11d extending in the axial direction. This slit 11d is elastically deformed and opened when the shaft 5 is fitted into the fitting hole 11c.

Incidentally, the transparent portion 10 and the opaque portion 11 are integrated with each other via an adhesive or the like to form the operating knob 2.

When the operating knob 2 having the above structure is attached to the shaft 5 as shown in FIGS. 1 and 2, the operating knob 2 fits into the opening 1a of the front panel 1, and its upper surface 6 is exposed through the opening 1a. When viewing each operation knob 2 arranged on the front panel 1 in this way from above, the scale plate 7 can be seen through the transparent part 10 of the operation knob 2.
The colored bodies 8a to 8j and the scale 9 formed thereon can be visually observed.

Therefore, each colored body 8a to 8j through the transparent part 10
It can be seen that the large number of operation knobs 2 are color-coded according to their functions. Further, the amount of operation of each operating knob 2 can be known from the scale 9 with reference to the position of the protrusion 10b.

In this way, the operation knob 2 is not color-coded by attaching colored caps, but the colors of the colored bodies 8a to 8j on the lower side can be seen in a ring shape through the transparent part 10, which improves the aesthetic appearance. Are better. Moreover, since the operation knob 2 is not colored or attached with a color for each function, it can be used in common regardless of each function.

Therefore, it is not necessary to prepare operation knobs for each function, and it is sufficient to prepare one type of operation knob 2, thereby improving the yield of operation knobs 2. In addition, since the same operating knob 2 can be installed at any position during the production process, there is no need to worry about selecting the wrong operating knob for each function, which is required in the past, and work efficiency during assembly is improved. In addition to this, it also eliminates the work errors that occur in the past when operating knobs of different colors are attached incorrectly. In addition, since the transparent part 10 as the operating part of the operating knob 2 is thinned,
It has an excellent design and can be finely adjusted with good operability by pressing the protrusion 10c protruding on the periphery of the transparent part 10 with a fingertip. Further, since the protrusion 10c is arranged so as to overlap the scale 9, the amount of operation can also be determined from the rotational position with respect to the scale 9.

FIG. 5 shows a modification of the present invention. In FIG. 5, a colored body 13 and a scale 14 are provided on the upper surface of the front panel 12.
A scale sheet 15 on which is printed is attached.
The operation knob 2 is attached to the shaft 5 so as to face the colored body 13 and the scale 14 of the scale sheet 15. Therefore, the operation knob 2 is arranged at a position separated from the front panel 12 by the thickness of the scale sheet 15. In this case, since the periphery of the operating knob 2 is exposed, there is a sufficient amount of light from the periphery, and the colored body 13 and scale 14 can be clearly seen through the transparent part 10.

In addition, in the above explanation, a colored body printed with a predetermined color and a scale sheet with a scale printed thereon are pasted on the bottom or top surface of the front panel, so that the colored body and scale are visible through the transparent part of the operation knob. However, the present invention is not limited to this, and it goes without saying that the colored body may be formed directly on the panel facing the operation knob, for example.

Furthermore, although the above embodiment has been described using an example of an operation knob applied to a mixer, the present invention is not limited to this, and can of course be applied to operation knobs used in devices such as other electronic devices.

Effects of the invention As mentioned above, the operation knob structure according to the present invention is such that the colored body and scale provided below the operation part can be seen from above through the transparent operation part, and it is possible to perform multiple operations. When color-coding parts by function,
There is no need to prepare multiple types of operation knobs colored in different colors, and simply attach the operation knobs with a common operation section above the colored bodies that are colored according to each function, so there is no need to use operation knobs of different colors by mistake. This prevents accidental attachment and facilitates assembly work. Furthermore, the operating knob is made thinner, and fine adjustments can be made easily because the projections on the operating section can be pressed with a fingertip and rotated in accordance with the scale.

In addition, since the operation knob mounting shaft of the operated part is covered with an opaque part that fits into the center hole of the operation part, the central shaft cannot be seen as if the entire operation knob were made transparent, and the appearance is different. It can be configured so that it does not look unsightly. Furthermore, the color-coded operation knobs can be made common, which improves the yield of operation knobs in the production process and improves assembly work efficiency.
