On the other hand, when any one of the pair of push button knobs 310 is pressed, the switch 115 opposite thereto is turned on by the pressing portion 311 of the pressed push button knob 310. When the push on the push button knob 310 is released, the switch 115 is turned off. When the light emitting element 117 emits light, the push button knob 310 is brightly illuminated from the lower surface side and illuminated.

  By the way, the main board 250 is generally composed of a hard board (printed wiring board), and the attachment insertion portion 253 is processed by a machine tool or the like. Therefore, the position of the attachment insertion portion 253 is not necessarily formed with a precise dimension. In addition, in general, since one main board 250 is attached to one outer case 10, a plurality of rotary electronic component main bodies 50 attached to the main board 250 as in the conventional case is used as the outer case 10. When attached, as described above, the position of each rotary electronic component main body 50 with respect to the outer case 10 is likely to cause an error, and it is difficult to install the rotary electronic component main body 50 at a precise position. However, according to the present invention, the rotary electronic component main body 50 is directly attached to the outer case 10 and the main board 250 is attached to the outer case 10 separately from the rotary electronic component main body 50. 12, the functional component storage portion 79 of the rotary electronic component main body 50 can be positioned and installed easily and accurately. Further, according to this embodiment, the functional component storage portions 79 of the plurality of rotary electronic component main bodies 50 can be positioned and installed with high accuracy in the plurality of openings 12 provided in the exterior case 10. Further, since the flexible circuit board 100 and the main board 250 are electrically connected via the flexible connecting portion 111, the mounting position shift of the main board 250 to the exterior case 10 is the position of the rotary electronic component main body 50. Will not be affected. In this embodiment, the rotary electronic component main body 50 can be easily attached to the exterior case 10 by the mounting portion 73 provided on the rotary electronic component main body 50. In this embodiment, the main board 250 is attached to the exterior case 10 via the rotary electronic component main body 50 and a predetermined gap S. Therefore, other electronic components (not shown) are mounted in the gap S. (In this embodiment, other various electronic components (not shown) are mounted on the surface (upper surface) of the main substrate 250 facing the gap S, but instead of or together with the gaps of the rotary electronic component main body 50. Other various electronic components may be mounted on the surface facing S (lower surface). Since other electronic components can be mounted using the gap (space) S generated between the main board 250 and the rotary electronic component main body 50 in this way, the mounting density of the electronic components can be increased.

  In addition, as the synthetic resin (molding resin) constituting the exterior case 10, the mounting base 60, and the rotating body 170 used for the rotary electronic component 1 with the case, various synthetic resins can be used as long as they can be molded. For example, PMMA resin, ABS resin, PBT resin, POM resin, polycarbonate resin, acrylic resin, or the like can be used. The synthetic resin film 101 constituting the flexible circuit board 100 may be made of various other thermoplastic, thermosetting, and photocurable synthetic resin films such as polyphenylene sulfide (PPS) film in addition to PET film. , Polyimide (PI) film, Polyethylene naphthalate (PEN) film, Polyetherimide (PEI) film, Polyetheretherketone (PEEK) film, Polyetherketone (PEK) film, Polycarbonate (PC) film, Polybutylene naphthalate (PBN) film, polybutylene terephthalate (PBT) film, or the like can be used.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea described in the claims and the specification and drawings. Is possible. It should be noted that any shape, structure, and material not directly described in the specification and drawings are within the scope of the technical idea of the present invention as long as the effects and advantages of the present invention are exhibited. For example, in the above embodiment, the switch 115 and the light emitting element 117 are used as functional parts. However, functional parts that exhibit various other functions may be used. For example, another rotary electronic part, a seesaw switch, a swing type electronic part, etc. It may be a functional component (for example, a decorative board) having a function other than a component and an electrical function. In the above embodiment, a rotary switch (encoder) having a function of continuously outputting an ON / OFF waveform is installed as a rotary electronic component. However, a rotary switch that outputs another switch waveform, a resistor You may install the rotary electronic component which comprises the electrical function part from which other various electrical outputs are obtained, such as a rotary variable resistor which changes a value. Although the example which provided the some opening part in one exterior case was shown in the said embodiment, this invention is applicable even if it provides one opening part in one exterior case.

  In the above embodiment, a flexible circuit board is used as the circuit board. However, a hard circuit board may be used. In this case, the circuit board and the main board are separately connected by a flexible connecting part (both electrical connection means) such as a flexible circuit board and a lead wire. In some cases, the functional component and the electrical functional unit may be connected to the main board by electrical connection means having no flexibility. Moreover, in the said embodiment, although the flexible circuit board and the main board | substrate were electrically connected by the connector and the male side connector, you may connect using other means, such as a conductive adhesive, for example. In the above-described embodiment, the hard circuit board is used as the main board. However, the flexible circuit board may be placed on a hard mounting member to replace it. The position where the attachment portion for attaching the rotary electronic component main body to the exterior case is not limited to the position of the above embodiment, and may be various other positions. The main board is not necessarily shared by a plurality of rotary electronic components. In some cases, the case may be a case other than the exterior case. Moreover, although the example which used the rotary electronic component concerning this invention as an interior electronic component of a motor vehicle was shown in the said embodiment, you may use as a rotary electronic component mounted in various apparatuses and apparatus other than a motor vehicle. Note that the structure of the switch 115 can be variously modified. For example, even a so-called membrane switch in which two synthetic resin films are laminated and a pair of contact patterns are opposed to each other through a thin gap. Alternatively, a single switch having a switch mechanism housed in the case may be used.
