  However, in the conventional multifunctional electronic component shown in Patent Document 1, the shaft portion (31) provided at the center of the display member (10) is inserted into the opening (103) provided at the center of the rotary knob (100). Therefore, when the outer peripheral dimension of the rotary knob (100) becomes relatively larger than the outer diameter dimension of the shaft section (31) (that is, the inner diameter dimension of the opening (103)), the shaft section ( 31) In contrast to the slight rattling (tilting) of the rotary knob (100) in the tilt direction, the rattling in the tilt direction (vertical direction) of the vicinity of the outer periphery of the rotary knob (100) increases. There was a fear. If the outer diameter of the shaft portion (31) is small, a strong force acts between the opening (103) and the shaft portion (31) when the vicinity of the outer periphery of the rotary knob (100) is rattled up and down. There is also a risk that the shaft support of the rotary knob (100) may be hindered (for example, the rotational torque increases).

  In addition, since the rotary knob (100) is pivotally supported by the central shaft portion (31) of the display member (10), the pivotal support portion cannot be used for other purposes, and the electronic components can be reduced in size accordingly. Conversion was inhibited.

Each fixing portion 173 is provided so as to be located in the middle of each connecting portion 171.

  The first circuit board part 131 and the second circuit board part 135 are formed on one flexible circuit board 130. That is, the flexible circuit board 130 is configured by providing a desired circuit pattern on a flexible synthetic resin film. In this embodiment, a thermoplastic polyethylene terephthalate (PET) film is used as the synthetic resin film.

  The support member 200 is formed of a hard plate (in this embodiment, a metal plate (for example, a stainless steel plate)), and is attached to each of the fixing bases 173 of the mounting base 150 at positions facing the mounting portions 173b. Part 201 is formed.

  Next, a method for assembling the rotary electronic component 1 will be described. First, the click plate 110 and the slider 120 are overlaid on the mounting surface 85 of the rotary knob 80 in advance. At this time, each mounting portion 91 of the rotary knob 80 is inserted into each mounting portion 117 of the click plate 110 and each mounting fixing portion 123 of the slider 120, and the tip of each mounting portion 91 is caulked with heat to thereby click the click plate 110. The slider 120 is attached to the rotary knob 80. On the other hand, the first circuit board part 131 is placed on the mounting base 150, and at that time, the board locking parts 165 of the mounting base 150 are inserted into the insertion parts 139 of the first circuit board part 131, and the tips thereof are heat-caulked. As a result, the first circuit board 131 is mounted on the mounting base body 151. At this time, the connecting part 149 of the flexible circuit board 130 is inserted into the gap between the mounting base 150 and the mounting base holding part 153 by inserting the board insertion part 169 provided on the mounting base 150.

  Next, the push button knob 10 is inserted into the knob housing part 35 of the display member 30, and at this time, the pressing part 13 of the push button knob 10 is inserted into the opening 55 of the display member 30. At this time, the guide protrusion 17 of the push button knob 10 is inserted into the guide portion 55b of the opening 55, and the guide protrusion 17 protruding to the lower surface side of the guide portion 55b is rotated 180 °. 3 and 5 show a state after the push button knob 10 is rotated by 180 °, the directions of the guide protrusion 17 and the guide portion 55b are different from each other by 180 °.

  Next, the display member 30 to which the pushbutton knob 10 is attached is inserted into the display portion storage portion 81 of the rotary knob 80 to which the click plate 110 and the slider 120 are attached, and the shaft portion 51 of the display member 30 is then inserted. The opening 83 of the rotary knob 80, the opening 115 of the click plate 110, and the opening 121 of the slider 120 are inserted.

  Next, the rotary knob 80 on which the above components are mounted is placed on the first circuit board portion 131 attached on the mounting base 150, and the shaft portion 51 of the display member 30 is click-engaged with the mounting base 150 at that time. The inner surface of the portion 161 is inserted, and the lower surface thereof is placed on the shaft contact surface 159. At this time, each mounting portion 53 on the lower surface of the shaft portion 51 is inserted into each mounted portion 163 of the mounting base 150, and the tip thereof is heat-caulked on the lower surface of the mounting base 150.

  When the display member 30 is placed on the mounting base 150, as shown by a dotted line in FIG. 7, the guide portion closing portion 157 of the mounting base 150 is inserted into the guide portion 55 b of the opening 55 of the display member 30 to close it. The opening 55 is only the circular portion 55a, and the pressing portion 13 of the push button knob 10 is reliably guided.

  Then, the mounting base 150 is placed on the second circuit board portion 135 placed on the support member 200, and at this time, the mounting portions 173 b of the fixing portions 173 of the mounting base 150 are attached to the second circuit board portion 135. The attachment portion 148 and the attached portion 201 of the support member 200 are inserted, and the tip of the attachment portion 148 is heat caulked by the lower surface of the support member 200. Thereby, the rotary electronic component 1 is completed. The above assembling procedure is an example, and it goes without saying that the assembly may be performed using other various assembling procedures.

  In the rotary electronic component 1 configured as described above, when the rotary knob 80 is rotated, the slider 120 attached to the rotary knob 80 rotates integrally with the rotary knob 80, and the contact portion 127 of the rotary knob 80 is slid. The detection output from the sliding contact pattern 137 changes by sliding on the top. At the same time, the click plate 110 rotates integrally with the rotary knob 80, and the click elastic contact portion 114 gets over the unevenness of the click engagement portion 161 of the mounting base 150, and a click feeling is generated. By the way, when the click elastic contact portion 114 rides on the convex portion of the click engaging portion 161, the arm portion 113 of the click plate 110 faces the opening 83 of the rotary knob 80. And the arm portion 113 enters the opening 83 of the rotary knob 80. That is, it is not necessary to separately provide a space in which the elastic contact portion 114 and the arm portion 113 move up and down between the rotary knob 80 and the mounting base 150. From this point, the rotary electronic component 1 can be made thinner.

  Next, when the operation part 15 of the push button knob 10 is pressed, the push button knob 10 is lowered, the pressing part 13 presses the reversing plate 145a of the central switch 145 and reverses, and the central switch 145 is turned on. When the push on the push button knob 10 is released, the push button knob 10 returns to the original position by the elastic return force of the reversing plate 145a, and the central switch 145 is turned off.

  If the upper surface portion (the upper surface portion on the outer side in the radial direction of the index 37) corresponding to any of the indexes 37 of the knob operation unit 89 of the rotary knob 80 is pressed downward, the rotary knob 80 or the display member. 30 and the push button knob 10 and the like, the entire components installed on the mounting base 150 are tilted and swung in the direction of being pressed integrally with the mounting base 150, and the pressing switch 167 on the lower side faces the pressing switch. The reversing plate 147a of 147 is pressed and reversed, and the pressing switch 147 is turned on. The mounting base 150 is inclined when the connecting portion 171 and the mounting base holding portion 153 are bent. When the pressure on the rotary knob 80 is released, the rotary knob is caused by the elastic return force to the original shape of the bent connecting portion 171 and the mounting base holding portion 153 and the elastic return force of the inverted reversing plate 147a. All of the swinging components such as 80 and mounting base 150 are automatically restored to their original positions, and the pressing switch 147 is turned off.

  As described above, the rotary electronic component 1 has the display member 30 including the mounting base 150, the shaft portion 51 fixed on the mounting base 150, and the display portion 31 projecting radially outward from the shaft portion 51. A rotary knob 80 rotatably installed between the mount 150 and the display unit 31 of the display member 30, a slider 120 that changes an output signal by the rotation of the rotary knob 80, and a detection pattern 137. And a rotation engaging portion 90 that rotatably supports the rotary knob 80 on the lower surface of the display portion 31 of the display member 30.

  As described above, according to the rotary electronic component 1, the rotary knob 80 is pivotally supported by the rotation engaging portion 90 provided on the lower surface of the display portion 31 of the display member 30. The diameter of the part 51 can be easily made larger than the diameter. As a result, the backlash of the rotary knob 80 in the tilt direction (vertical direction, arrow B direction in FIG. 1) can be further reduced. Further, even when a force is exerted to rattle the vicinity of the outer periphery of the rotary knob 80 in the vertical direction (arrow B direction), the force applied to the rotary engagement portion 90 can be small, and the rotary knob 80 can be made smooth. Rotation can be maintained. Further, the portion around the shaft portion 51 of the display member 30 can be used for other purposes (in this embodiment, the click mechanism is installed), and the rotary electronic component 1 can be reduced in size accordingly. Further, since the shaft portion 51 of the display member 30 does not pivotally support the rotary knob 80, the outer diameter can be easily reduced. From this point, the rotary electronic component 1 can be downsized.
