Next, the overlapped intermediate portion 140, contact pattern forming portion 150, and insulating portion 160 are folded back at the connection portion 173 and installed on the lower surface of the mounting plate 190 (at this time, the intermediate portion 140 contacts the lower surface of the mounting plate 190). At that time, a pair of mounting projections 197 provided on the lower surface of the mounting plate 190 is inserted into mounting holes 145, 155, 165 provided in the intermediate portion 140, the contact pattern forming portion 150, and the insulating portion 160, and both mounting projections 197 are inserted. Fix it by caulking the tip. Thus, the substrate laminate 100 shown in FIG. 2 is completed. As shown in FIG. 2, the ground pattern 180 formed in the ground pattern forming portion 120 is exposed in the opening 131 formed in the sliding contact pattern forming portion 130. In addition, a pressing switch 151 including switch contact patterns 151 a and 151 b is disposed in the opening 131 of the sliding contact pattern forming unit 130.

  Next, as shown in FIG. 2, the support plate 200 is formed by forming a metal plate into a substantially disc shape having an outer diameter substantially the same as the outer diameter of the substrate laminate 100, and the ground pattern in the vicinity of the outer periphery thereof. A case mounting portion 203 having a plurality of (eight) penetrating small holes is provided at a position facing each case mounting portion 123 of the forming portion 120 (a position facing when overlapped), and the intermediate portion in the vicinity of the outer periphery. A hole 205 made of a small hole is provided at two positions (positions facing each other when overlapped) at two positions facing the 140 mounting holes 145.

  Next, the assembly method of the rotary electronic component 1-1 with a press switch is demonstrated. First, in FIG. 1, the operation knob 10 is placed on the protruding portion 41 of the case 40 to which the click spring 81 is attached. At this time, the shaft portion 17 of the operation knob 10 is rotatably inserted into the opening 47 of the case 40. Next, the main body portion 31 of the push button knob 30 is inserted into the insertion portion 15 of the operation knob 10 from the lower surface side of the case 40, and the rotating body 50 with the click plate 91 attached thereto is further disposed below the main body portion 31. At this time, the pressing portion 35 of the push button knob 30 is inserted into the pressing portion insertion portion 51 of the rotating body 50 so as to be movable up and down, and at the same time, the protrusions 19 of the operation knob 10 are connected to the insertion portions 99 of the click plate 91 and the rotating body 50. It is inserted into each protrusion insertion portion 55. Then, the tip of each protrusion 19 is caulked with heat on the lower surface of the rotating body 50. Next, the substrate laminate 100 and the support plate 200 are installed on the lower surface side of the rotating body 50. At that time, each ground pattern forming part 120, sliding contact pattern forming part 130, intermediate part 140, contact pattern forming part 150, insulating part FIG. 3 shows a plurality of case mounting portions 123, 133, 143, 153, 163, and 193, which are provided on the mounting plate 190 and overlap with each other in the vertical direction, and the case mounting portion 203 of the support plate 200. The mounting protrusions 48 of the case 40 shown are inserted, and the tips of the mounting protrusions 48 are caulked on the lower surface of the support plate 200 to integrate these members. The hole 205 provided in the support plate 200 is a clearance hole for inserting the thermally crimped tip portion of the mounting protrusion 197 of the mounting plate 190 exposed on the lower surface of the insulating portion 160.

  When the operation knob 10 is rotated in the rotary electronic component 1-1 with the pressure switch, the rotating body 50 rotates integrally therewith, and the sliding booklet 63 of the slider 60 rotates on the sliding contact pattern 137. While sliding, the electrical output changes. On the other hand, when the push button knob 30 is pressed, the pressing portion 35 presses the pressing switch 151 to reverse the reversing plate 151c and turn it on. When the pressing on the push button knob 30 is released, the reversing plate 151c automatically returns to its original shape and the pressing switch 151 is turned off. On the other hand, when a finger or the like for operating the operation knob 10 or the push button knob 30 is charged, the surface of the operation knob 10 is subjected to conductive metal plating. After entering and conducting the plated surface of the operation knob 10, it enters the upper surface side of the rotating body 50 from the opening 47 of the case 40. Then, the static electricity that has entered the upper surface side of the rotating body 50 enters the click spring 81 or the click plate 91 made of a metal plate (note that the static electricity that has entered the click spring 81 is guided to the click plate 91 in contact with the click spring 81). The tip of the earth lead portion 97 provided on the plate 91 is discharged to the earth pattern 180 disposed close to the earth lead portion 97 and grounded. Therefore, the static electricity incident on the upper surface side of the rotating body 50 from the operation knob 10 and the push button knob 30 is applied to the slider 60, the sliding contact pattern 137 and other circuit patterns which are electrical function units installed on the lower surface side of the rotating body 50. There is no incidence and static electricity can be effectively prevented from entering the electric circuit.

  In this embodiment, the surface of the shaft portion 17 of the operation knob 10 is not plated, so that static electricity conducted through the plating is not conducted to the shaft portion 17. Static electricity does not enter the lower surface side through the protruding portion insertion portion 55 provided for fixing (static electricity is reliably caught by the click plate 91 on the lower surface before passing through the protruding portion insertion portion 55). . In the case of this embodiment, since the ground pattern 180 for introducing static electricity is provided in the ground pattern forming portion 120 different from the sliding contact pattern forming portion 130 in which the sliding contact pattern 137 is formed, both patterns are on the same surface. It is also possible to reliably prevent discharge between the two that may occur in the case of. In this embodiment, the sliding contact pattern forming unit 120 and the ground pattern forming unit 130 are the same flexible circuit board 110, but the sliding contact pattern 137 and the ground pattern 180 are provided on different upper and lower surfaces of the flexible circuit board 110. Therefore, no discharge occurs between the two from this point.

  In the above-described embodiment, the ground pattern forming unit 120 is provided as a countermeasure against static electricity. However, the ground pattern forming unit 120 may be omitted if it is not necessary. Further, the insulating portion 160 may be omitted.

  As described above, the substrate laminate 100 is provided with at least the sliding contact pattern 137 that is in sliding contact with the slider 60 while rotating, and the sliding contact pattern forming portion 130 that is provided with the opening 131 at the center of rotation of the slider 60. And a contact pattern forming part 150 provided with switch contact patterns 151a and 151b for pressing switches, and an intermediate part 140 installed between the sliding contact pattern forming part 130 and the contact pattern forming part 150. A plurality of flexible circuit boards 110 connected by the portions 173 and 175, the sliding contact pattern 137 and the switch contact patterns 151a and 151b are formed on the same surface of the flexible circuit board 110, and the sliding contact pattern is formed. A contact pattern is formed on the lower surface side of the surface of the portion 130 where the sliding contact pattern 137 is provided. 150 are stacked in this order in a zigzag manner so that the sliding contact pattern 137 and the switch contact patterns 151a and 151b are directed to the same surface side, and the switch contact patterns 151a and 151b are included in the opening 131 of the sliding contact pattern forming portion 130. A push switch 151 is arranged. That is, the substrate laminate 100 having a plurality of functional patterns (sliding contact pattern 137 and switch contact patterns 151a and 151b) can be easily manufactured with a small number of parts by simply folding and overlapping one flexible circuit board 110. In addition, since it is only laminated, the thickness can be reduced. In that case, since the intermediate part 140 is provided in addition to the sliding contact pattern forming part 130 and the contact pattern forming part 150 on one flexible circuit board 110, the flexible circuit board 110 is folded in a zigzag shape and overlapped. The sliding contact pattern 137 and the switch contact patterns 151a and 151b can be easily arranged on the same surface without using a complicated circuit configuration such as a through hole.

  In addition, since the rigid mounting plate 190 is installed and overlapped between the stacked sliding contact pattern forming unit 130 and the contact pattern forming unit 150 on the substrate laminate 100, the slider 60 has the sliding contact pattern 137. Even if it slides on the surface, the sliding contact pattern forming portion 130 made of synthetic resin film does not dent due to an increase in the elastic pressure and the ambient temperature, and it is possible to prevent noise from being generated in the output, and the formation described above. It is also possible to prevent a click sensation from occurring when the slider 60 passes through the formed recess. Further, since the sliding structure pattern forming part 130 and the switch contact pattern forming part 150 are fixed to the upper surface side and the lower surface side of the mounting plate 190, respectively, the integrated substrate stacking body 100 can be configured.
