Next, the rotating body 30 is placed on the slider fixing plate 50. At this time, the protrusion of the rotating body 30 is rotatably inserted into the hole 64 of the slider fixing plate 50 and is pivotally supported.
At this time, the sliding contact 531 of each slider 53 is in elastic contact with the movable contact pattern 33 on the lower surface of the rotating body 30, while the click protrusion 73 of the click plate 57 is the click engaging portion 35 on the side of the rotating body 30. It is elastically touching.

Then, the upper case 90 is covered from above the rotating body 30, and the shaft 32 of the rotating body 30 is inserted into the through hole 93. Then, when each locking piece 81 of the bottom plate 80 is inserted into the locking concave groove 95 and the upper part thereof is bent on the upper surface of the upper case 90, the rotary electronic component 100 is completed. When the shaft 32 is rotated, the sliding contact 531 of each slider 53 comes into sliding contact with the movable contact pattern 33, and its on / off output can be taken out to each terminal 55.
At this time, since the click projection 73 of the click plate 57 is in elastic contact with the click engagement portion 35 on the side surface of the rotator 30, the click sensation is repeated each time the engagement and disengagement of the unevenness is repeated.

In this case, the adhesive sheet 20 is formed of a light-guiding sheet material, and the light from the light emitting member 9 is transmitted through the movable portion 16b of the first knob 16 to the pressing portion 18a of the third knob 18. It comes to lead to the surface.

  The third knob 18 can be moved up and down together with the movable portion 16b of the first knob 16, and can be moved up and down (lifted and lowered) in the insertion hole 17a of the second knob 17. The movable member 16b of the first knob 16 and the third knob 18 constitute a pressing member that can be moved up and down at the center of the operation member 15.

The operating member 15 is engaged with the engaging protrusion 12c of the rotating plate 12, is inserted into the insertion hole 14a of the frame 14, and is disposed on the upper surface side of the housing 1 so as to be rotatable and movable up and down. Also, at this time, the driving member disposed in the second storage portion 1b of the housing 1 is below the movable portion 16b of the third knob 18 and the first knob 16 which are pressing members provided in the center. 7 is arranged.
And the upper surface of a pair of protrusion part 7b of the both sides of the accommodation recessed part 7a in which the light emission member 9 of this drive member 7 was accommodated, and the lower surface of the movable part 16b of the 1st knob 16 are in the state contact | abutted. When the pressing portion 18a of the third knob 18 constituting the pressing member is pressed, the movable portion 16b presses the driving member 7, and the driving protrusion 7c presses the movable contact 5 disposed on the lower surface side. To reverse it.

  In the above embodiment, the housing 1 is provided with the guide member 10 that guides the raising and lowering of the drive member 7, and the guide member 10 supports the wiring member 8 to which the light emitting member 9 is attached, and the drive. The member 7 is provided with a housing recess 7a for housing the mounting portion 8b of the light emitting member 9 of the wiring member 8. A pair of projecting portions 7b are formed on both sides of the housing recess 7a, and the pair of projecting portions 7b. Since the contact surface with the lower surface of the movable portion 16b of the first knob 16 is formed on the upper surface of the first knob 16, the contact surface with the lower surface of the pressing member accommodates the mounting portion 8b of the light emitting member 9 of the wiring member 8. Since it is formed on the upper surface of the ridge 7b on both sides of the housing recess 7a, no stress is applied to the wiring member 8 during the rotational movement operation of the operation member 15 or the pressing operation of the pressing member, and high reliability is obtained. Become a thing There.

At this time, the inclined surface 16e provided on the lower surface of the movable portion 16b of the first knob 16 and the light emitting member 9 housed in the housing recess 7a of the driving member 7 are disposed facing each other. By irregularly reflecting the light emitted from the light emitting member 9 on this inclined surface, the operation surface on the surface of the pressing portion 18a of the third knob 18 can be illuminated brightly and uniformly via the movable portion 16b. Yes.
In addition, since the entire pressing member including the contact surface that contacts the driving member 7 is made of a light-guiding material, the light from the light emitting member 9 can be efficiently taken and incident on the operation surface. It is possible to do.

According to the embodiment of the present invention described above, the rotating body 12 that is rotatably held by the housing 1 and has a plurality of concave and convex cam portions 12d on the outer peripheral side surface portion, and is embedded in the rotating body 12 and exposed to one surface side. A code pattern 13 provided in contact with the code pattern 13, a slider 2 that slidably contacts the code pattern 13 and outputs a signal, and a click member 4 that abuts the cam portion 12d when the rotating body 12 rotates to generate a click feeling. A plurality of through holes 12e penetrating vertically in an inner surface surrounded by the outer peripheral side surface portion of the rotating body 12, and a metal plate connected to the code pattern 13 in the through hole 12e. Since the cut part 13a is exposed and provided, the exposed part of the metal plate can be cut and separated from the frame body 21 constituting the outline of the metal plate using the through hole 13e.
For this reason, the cutting portion 13a does not protrude outward from the outer peripheral side surface portion of the rotating body 12, and an uneven cam portion 12d for click can be formed on the outer peripheral side surface portion where the cutting portion 13a is located, so that design freedom This makes it possible to provide a rotating electronic component with a high click function.
According to the above-described embodiment of the present invention, the rotary electronic component is described as being housed in the housing having the housing recess. However, a flat circuit board may be configured as the housing, and the slider Alternatively, the click member may be provided on a holding member separate from the housing. Further, a slider may be provided on the rotating body, and a code pattern may be provided on the housing side.
