[0032]
Next, the portion 33 of the rotary electronic component substrate 90 and the portion of the first substrate 30 are inserted into the insertion portion 55 of the shaft support member 50 from above, and then placed on the placement portion 51 of the shaft support member 50. The second base 110 is placed, and each locking piece 113 is inserted into each small hole 57 and is bent and fixed on the back surface thereof. At this time, the connecting portion 35 passes through the substrate storage portion 59.
[0033]
Next, the drawer portion 33 of the rotary electronic component substrate 90 and the portion of the first substrate 30 are placed above the opening 41 of the first rotary mold 40 to which the click plate 60, the first slider 70 and the coil spring 80 are attached. And the shaft support 53 of the shaft support member 50 is inserted into the opening 41 so as to be rotatably supported. Next, the first substrate 30 is positioned under the first rotary mold 40 and below it. The first click plate 20 and the first base 11 are arranged in the two, and two of the four small projections 54 provided on the shaft support member 50 are thereby fixed to the two fixing holes of the rotary electronic component substrate 90. 38, and four small protrusions 54 are further inserted into the four small holes 21 provided in the first click plate 20 and the four small holes 13 provided in the first base plate 11, and the tips thereof are heat caulked.

At this time, the pressing protrusion 15 of the first base 11 is inserted into the pressing protrusion storage portion 49 on the lower surface of the first rotary mold 40.
[0034]
As shown in FIG. 1, the double rotary electronic component includes a first rotary electronic component 10 in which a first rotary mold 40 is rotatably installed on a first substrate 30, and a second substrate 120. The second rotary electronic component 100 in which the second rotary mold 130 is rotatably installed is the same as the rotation center axis of the first rotary mold 40 and the rotation center axis of the second rotary mold 130. The second rotary electronic component 100 is disposed on the first rotary electronic component 10 so that the second rotary electronic component 100 is rotated by the second rotary knob 160 that rotates the second rotary electronic component 100. Since it comprised so that a functional part might be covered, the double rotation type electronic component which has many functions can be attached to an apparatus with a small installation area.
[0035]
Also, since the first substrate 30 and the second substrate 120 are provided on both sides of the flexible sheet via the connecting portion 35 on one flexible sheet, and the portion of the connecting portion 35 is inserted through the rotation center portion of the first rotary mold 40. The second substrate 120 and the first substrate 30 can be easily and compactly installed above and below the first rotary mold 40.
[0036]
Next, the operation of the double rotary electronic component will be described. In FIG. 1, if the second rotary knob 160 on the upper side is rotated, the second rotary object 130 is rotated integrally therewith, and the second slider 170 slides on the switch pattern 121 of the second substrate 120 to At the same time as the on / off state is changed, the elastic contact portion 183 of the click spring 180 repeats insertion / removal to / from the click engagement hole 141 of the second click plate 140, thereby generating a click feeling. The rotation range of the second rotary mold 130 is a range in which the stopper 165 provided on the second rotary knob 160 can move within the stopper insertion groove 153 provided on the case 150.
[0037]
On the other hand, when the first rotary mold 40 is rotated in one direction (direction in which the end face of the coil spring 80 is pressed) by pushing and rotating the operation knob 42, the pressing protrusion 15 located in the pressing protrusion storage portion 49 is moved. One end surface of the coil spring 80 is pressed to compress and contract the coil spring 80 in the coil spring housing portion 47. At this time, the first slider 70 slides on the switch pattern 31 of the first substrate 30 and changes its on / off state. When the pressing of the operation knob 42 is released, the first rotary mold 40 is automatically returned to the original position by the elastic force of the coil spring 80. When the operation knob 42 is pushed in the reverse direction to rotate the first rotary mold 40, the first slider 70 slides on the switch pattern 31 to change its on / off state, and at the same time, is attached to the first rotary mold 40. The click portion 63 of the click plate 60 engages with the click engagement hole 23 of the first click plate 20, and a click feeling is generated at that time. The first rotary type 40 does not rotate before the position where the elastic portion 63 of the click plate 60 is engaged with the click engagement hole 23. This is because the rotation range of the first rotary type 40 is restricted by the range in which the stopper 56 (see FIG. 5) provided on the shaft support member 50 moves within the stopper storage portion 43 provided on the first rotary type 40. Because.
[0038]
That is, this double-rotating electronic component is configured such that a large number of switches are switched by rotating the second rotating mold 130, while the first rotating mold 40 is in the neutral position and while pressing the coil spring 80. The switch is configured to be switched at three positions, that is, a position to rotate and a position to rotate in the opposite direction to generate a click sensation.
[0039]
By the way, the first substrate 30 is inserted into the insertion portion 55 of the shaft support member 50 at the time of assembly. In the above embodiment, the first substrate 30 is provided so as to protrude in an arc shape from one side surface of the connecting portion 35. Therefore, it can be easily bent and can be inserted easily.
[0040]
Further, in the present invention, the second substrate 90 is formed on the first substrate 30 by bending the rotary electronic component substrate 90 in which the first substrate 30 and the second substrate 120 are connected by the connecting portion 35 into a substantially “Z” shape. Since 120 is disposed, the circuit pattern formed on the rotary electronic component substrate 90 may be formed on only one surface, and the manufacture thereof is facilitated. In particular, in the above-described embodiment, when the connecting portion 35 is bent so that the second substrate 120 is disposed immediately above the first substrate 30, the arc-shaped switch pattern formed on the first substrate 30 by the connecting portion 35 ( Since the first sliding contact pattern) 31 is bent near the center of the arc, the connecting portion 35 can be easily passed through the insertion portion 55. Further, since the connecting portion 35 is passed through the inside of the rotary electronic component, the middle portion of the rotary electronic component substrate 90 does not come out, and the size can be reduced.
[0041]

Is possible. Note that any shape, structure, or material not directly described in the specification and drawings is within the scope of the technical idea of the present invention as long as the effects and advantages of the present invention are exhibited.
[0043]
【The invention's effect】
As described in detail above, the present invention has the following excellent effects.
That is, since the first substrate and the second substrate are formed on both sides of the flexible sheet via the connecting portion on one flexible sheet, the number of components can be reduced. Further , by inserting the connecting portion through the insertion portion of the shaft support member , the first substrate is installed at the lower portion of the shaft support member and the second substrate is installed at the upper portion of the shaft support member . Without pulling out the drawer from between the first rotary electronic component and the second rotary electronic component, the size can be reduced and the structure can be simplified.
