A rotation side member to which a plate 110 and a click plate 70 having a click elastic contact portion 79 elastically contacting the click engagement portion 165 are provided, and the slider plate 11 Polymerization plate 200 obtained by superimposing the click plate 70 and can be said to have been constructed attached to the rotatable member. Since the slider plate 110 and the click plate 70 are placed so as to overlap with each other in this way, the detecting means including the slider plate 110 and the click mechanism including the click plate 70 and the like are provided on one surface of the superposition plate 200. Can be installed in the same space on the side (gap space between the rotary knob 10 and the mounting base 150), and thereby the thickness of the rotary electronic component 1-1 can be reduced.

  That is, in the rotary electronic component 1-1, the slider plate 110 has the opening 111 at the center and the sliding booklet 115 is disposed so as to surround the opening 111. The sliding contact 117 is provided, and the sliding contact 117 is protruded toward the opposite side of the surface of the slider plate 110 on which the click plate 70 is superimposed, while the click elastic contact portion 79 of the click plate 70 is provided. When the click plate 70 is overlapped with the slider plate 110, the click plate 70 is configured to protrude through the opening 111 of the slider plate 110 toward the side where the sliding contact 117 protrudes. Yes. With this configuration, the sliding contact 117 of the slider plate 110 and the click elastic contact portion 79 of the click plate 70 face the same direction, so that the detection means and the click mechanism are connected to one of the overlapping plates 200 as described above. It can be installed in the same space on the surface side. Therefore, unlike the multifunctional electronic component of Patent Document 1, it is not necessary to install the detection means and the click mechanism in the space above and below the rotary knob, and the thickness of the rotary electronic component 1-1 can be reduced. I can plan. Further, since the click elastic contact portion 79 of the click plate 70 passes through the opening 111 of the slider plate 110, the click elastic contact portion 79 and this elastically contact with the empty space inside the sliding contact 117 of the slider plate 110. The click engagement portion 165 can be disposed, and thereby the outer diameter of the rotary electronic component 1-1 can be reduced.

  In addition, the rotary electronic component 1-1 includes a shaft portion 17 provided on the rotation side member by inserting a shaft portion 17 provided on the rotation side member into a shaft support hole 53 provided on the stationary side member. The overlapping plate 200 having a portion whose outer diameter is larger than the outer diameter of the portion 17 is attached to a portion protruding through the shaft support hole 53 of the shaft portion 17, whereby the shaft portion 17 is removed from the shaft support hole 53. Is preventing. In this way, the overlapping plate 200 formed by overlapping the slider plate 110 and the click plate 70 has a function of preventing the shaft portion 17 of the rotation side member from coming off from the shaft support hole 53 of the stationary side member. There is no need to prevent the removal by using a dedicated component separately, and the number of components can be reduced and the cost can be reduced. Further, as described above, it is not necessary to interpose a separate component for preventing the removal, so that the thickness of the rotary electronic component 1-1 can be reduced.

  The rotary electronic component 1-1 includes a rotary knob 10 having a rotation side member having the shaft portion 17, and a case 50 in which the stationary side member is provided with the shaft support hole 53. The first circuit board portion 171 is provided at the lower portion of the case 50 to form the sliding contact pattern 179, and the shaft portion 17 of the rotary knob 10 is inserted into the shaft support hole 53 of the case 50. The overlapping plate 200 is attached to a portion that is penetrated and protruded, and a click engagement portion 165 is disposed at an inner position where the sliding contact pattern 179 of the first circuit board portion 171 is provided. With this configuration, the shaft portion 17 of the rotary knob 10 is rotatably inserted into the shaft support hole 53 of the case 50 to support it, and the first circuit board portion 171 is installed below the case 50. The present invention can be effectively applied to the rotary electronic component 1-1 having the structure as described above.

  The rotary electronic component 1-1 also includes a click plate 70 which is formed in a ring shape and overlaps the slider plate 110, and a click elastic contact installed in the opening 73 in the center of the attachment portion 71. A portion 79 and a connecting portion 77 for connecting the attachment portion 71 and the click ball contact portion 79 are provided. Thus, since the attaching part 71 of the click plate 70 is overlapped with the slider plate 110, the strength of the superposed plate 200 is increased. Accordingly, if this overlapped portion is attached to the rotary knob 10, it can be firmly attached. At the same time, the portion of the click elastic contact portion 79 does not have to overlap with the slider plate 110, so that the elastic force (elastic force) is not hindered by the overlap with the slider plate 110, and the effect Elastic force can be maintained.

  By the way, it is also possible to combine the function of the slider and the function of the click plate on one metal plate. However, this configuration has the following problems. That is, it becomes difficult to independently adjust the elastic force (ie, click feeling) of the click elastic contact portion and the contact pressure of the sliding contact of the slider plate, and the degree of freedom of adjustment of both is reduced. End up. For example, when the plate thickness is increased, the click feeling and the rotational torque become heavier (stronger), but the sliding contact pattern is scraped and the sliding life is shortened. On the other hand, when the plate thickness is reduced, the sliding life is extended, but the click feeling and the rotational torque are reduced. On the other hand, when the click plate 70 and the slider plate 110 are two separate parts as in the present invention, adjustment of the resilience (ie, click feeling) and rotational torque of the click elastic contact portion 79 and the sliding torque are performed. Since the contact pressure of the sliding contact 117 of the moving plate 110 can be adjusted independently and independently, the degree of freedom for adjusting both is increased. For example, since the slider plate 110 is an electrical function part, it is necessary to strictly manage its spring pressure. However, the click plate 70 only needs to have a mechanical click feeling and rotational torque, so that the spring pressure is managed. Don't have to be so strict. That is, the material and thickness of the slider plate 110 and the click plate 70 can be freely changed according to the purpose of both, and the contact pressure of the sliding contact 117 is strictly controlled (the maximum and minimum width is narrow). In addition, it is possible to easily manage the click resilience and rotational torque of the click plate 70 which are relatively strict (the maximum and minimum widths are wide). Further, the click plate 70 can be made of a material (for example, stainless steel) whose material cost is lower than that of the material (for example, phosphor bronze) of the slider plate 110, and the cost can be reduced. In addition, these effects obtained as the polymer plate are similarly generated in the following examples.

The moving contact 427 protrudes toward the protruding side (the front side in FIG. 10).

  On the other hand, as shown in FIG. 9, the first circuit board portion 431 is placed on the mounting base 450, and at that time, the board locking portions 465 of the mounting base 450 are inserted into the insertion portions 439 of the first circuit board portion 431. And the 1st circuit board part 431 is attached on the mounting base 450 by heat-staking the front-end | tip. At this time, the connecting portion 449 of the flexible circuit board 430 is passed through the board insertion portion 469 provided in the mounting base 450 to be inserted into the gap between the mounting base 450 and the mounting base holding portion 453.

  Next, the push button knob 310 is inserted into the knob housing portion 335 of the display member 330, and the pressing portion 313 is inserted into the opening 355 of the display member 330. At this time, the guide protrusion 317 of the push button knob 310 is inserted into the rectangular portion of the opening 355, and the guide protrusion 317 protruding to the lower surface side of the shaft portion 351 is rotated 180 °. FIG. 8 shows a state after the push button knob 310 is rotated by 180 °, so that the directions of the rectangular portion of the guide protrusion 317 and the opening 355 are different by 180 °.

  Next, the display member 330 to which the pushbutton knob 310 is attached is inserted into the display portion storage portion 381 of the rotary knob 380 to which the overlapping plate 400 is attached, and the shaft portion 351 of the display member 330 is then opened to the opening of the rotary knob 380. The part 383 and the opening 415 of the click plate 410 and the opening 421 of the slider plate 420 are inserted.

  Next, the rotary knob 380 on which the respective components are mounted is placed on the first circuit board portion 431 attached to the mounting base 450, and the shaft portion 351 of the display member 330 is then clicked on the click engaging portion of the mounting base 450. It is inserted inside 461, and its lower surface is placed on the shaft contact surface 459. At this time, each mounting portion 353 on the lower surface of the shaft portion 351 is inserted into each mounted portion 463 of the mounting base 450, and the tip thereof is heat-caulked on the lower surface of the mounting base 450.

  When the display member 330 is placed on the mounting base 450, the closing portion 457 of the mounting base 450 is inserted into the rectangular portion of the opening 355 of the display member 330 to close it, and the opening 355 becomes only a circular portion, and the push button The pressing portion 313 of the knob 310 is reliably guided.

  The mounting base 450 is placed on the second circuit board portion 435 placed on the support member 500, and each fixing portion 473 of the mounting base 450 is connected to the attached portion 448 of the second circuit board portion 435. It is inserted into the attached portion 501 of the support member 500, and the tip thereof is heat caulked with the lower surface of the support member 500. Thereby, the rotary electronic component 1-2 is completed.

  In the rotary electronic component 1-2 configured as described above, when the rotary knob 380 is rotated, the slider plate 420 attached to the rotary knob 380 rotates integrally with the rotary knob 380, and the sliding contact 427 is By sliding on the sliding contact pattern 437, the detection output from the sliding contact pattern 437 changes. At the same time, the click plate 410 rotates integrally with the rotary knob 380, and the click elastic contact portion 414 gets over the unevenness of the click engagement portion 461 of the mounting base 450, and a click feeling is generated. By the way, when the click elastic contact portion 414 rides on the convex portion of the click engaging portion 461, the elastic contact arm 413 of the click plate 410 faces the opening 383 of the rotary knob 380. The part 414 and the elastic contact arm 413 enter the opening 383 of the rotary knob 380. That is, it is not necessary to provide a space where the click ball contact portion 414 and the ball contact arm 413 move up and down separately between the rotary knob 380 and the mounting base 450, and the rotary electronic component 1-2 can be thinned.

  Next, when the main body portion 311 of the push button knob 310 is pressed, the push button knob 310 is lowered and the pressing portion 313 presses the reverse plate of the central switch 445 to reverse it, and the central switch 445 is turned on. When the push on the push button knob 310 is released, the push button knob 310 returns to the original position by the elastic restoring force of the reversing plate, and the central switch 445 is turned off.

  Further, if the upper surface portion corresponding to any of the indexes 337 of the knob operation unit 389 of the rotary knob 380 (the upper surface portion on the radially outer side of the index 337) is pressed downward, the rotary knob 380 and the display member 330 are pressed. And the push button knob 310 and the like, and all the components installed on the mounting base 450 are tilted and swung in the direction of being pressed integrally with the mounting base 450, and the pressing part 467 on the lower side faces the pressing switch 447. The reversing plate is pressed and reversed, and the pressing switch 447 is turned on. The mounting base 450 is inclined when the connecting portion 471 and the mounting base holding portion 453 are bent. When the pressure on the rotary knob 380 is released, the rotary knob 380 is caused by the elastic force of the bent connecting portion 471 and the mounting base holding portion 453 to the original shape and the elastic return force of the inverted reverse plate. In addition, all the swinging components such as the mounting base 450 are automatically restored to the original positions integrally, and the pressing switch 447 is turned off.

  Here, the rotary knob 380 and the overlapping plate 400 that rotates together with the rotary knob 380 are referred to as a rotation-side member. When the first circuit board portion 431, the mounting base 450, the second circuit board portion 435, and the support member 500 are referred to as stationary members, the rotary electronic component 1-2 forms a sliding contact pattern 437 and is clicked. The stationary plate member provided with the engaging portion 461, the slider plate 420 having the sliding contact 427 that is slidably contacted with the sliding contact pattern 437 and is clickably engaged with the stationary member. A rotation side member formed by attaching a click plate 410 having a click elastic contact portion 414 that elastically contacts the portion 461, and the slider plate 420 and the click plate 410, The overlapping polymerization plate 400 was able that is constituted by attaching to the rotating side member. Since the slider plate 420 and the click plate 410 are installed so as to overlap with each other in this way, the detection means including the slider plate 420 and the sliding contact pattern 437, and the click mechanism including the click plate 410 and the click engagement portion 461. Can be installed in the same space on one surface side of the superposition plate 400 (a gap space between the rotary knob 380 and the mounting base 450), whereby the thickness of the rotary electronic component 1-2 can be reduced.

  More specifically, in the rotary electronic component 1-2, the slider plate 420 has an opening 421 at the center and a sliding booklet 425 is disposed so as to surround the opening 421. A sliding contact 427 is provided in the booklet 425, and the sliding contact 427 is further protruded toward the side opposite to the surface of the slider plate 420 where the click plate 410 is overlapped, while the click plate 410 is clicked. When the click plate 410 is overlapped with the slider plate 420, the elastic contact portion 414 protrudes through the opening 421 of the slider plate 420 toward the side where the sliding contact 427 protrudes. It is configured. With this configuration, the sliding contact 427 of the slider plate 420 and the click elastic contact portion 414 of the click plate 410 are directed in the same direction, so that the detection means and the click mechanism are connected to one of the overlapping plates 400 as described above. Can be formed in the same space on the surface side. Therefore, unlike the multifunctional electronic component of the above cited reference 1, there is no need to install a detection means and a click mechanism in the space above and below the rotary knob, and the thickness of the rotary electronic component 1-2 is reduced. I can plan. Further, since the click elastic contact portion 414 of the click plate 410 passes through the opening 421 of the slider plate 420, the click elastic contact portion 414 and this elastically contact with the empty space inside the sliding contact 427 of the slider plate 420. The click engagement portion 461 can be disposed, and thereby the outer diameter of the rotary electronic component 1-2 can be reduced.

  More specifically, the rotary electronic component 1-2 includes a rotary knob 380 having an opening 383 at the center of the rotary side member, while the stationary side member is installed below the rotary knob 380. The first circuit board portion 431 on which the sliding contact pattern 437 is formed, the shaft portion 351 erected at the center position where the sliding contact pattern 437 of the first circuit board portion 431 is provided, and the shaft portion 351 radially outward. And a display member 330 having a display portion 331 projecting on the upper surface side of the rotary knob 380, and on the surface of the rotary knob 380 facing the first circuit board portion 431. A superposition plate 400 is attached, and a click engagement portion 461 is disposed at a position around the shaft portion 451 on the inner side where the sliding contact pattern 437 of the first circuit board portion 431 is provided. With this configuration, the display member 330 is arranged at the center of the rotary knob 380 and the first electronic circuit board portion 431 is installed below the rotary knob 380. The invention can be applied effectively.
