2. Description of the Related Art In recent years, the functions of electronic devices such as televisions have become diversified and complicated. For this reason, conventionally, as a method of executing a desired function among a large number of functions in a TV remote control, a function to be performed by rotating a rotary knob of a rotary switch attached to the remote control is selected. Then, in that state, there is a type in which the selected function is set and executed by pressing a push button of a push button switch attached to the remote controller and turning it on.

If the rotary knob of the rotary switch and the push button of the push button switch are located at different positions, the operation becomes complicated. Therefore, by integrating the two and pressing the rotary knob of the rotary switch, Rotary switches with pushbutton switches that can be turned on and off have been put to practical use.

FIG. 5 is a perspective view of a main part showing a mechanism of a conventional rotary switch with a push button switch of this kind. As shown in the figure, the rotary switch 80 with a push button switch is
A cylindrical rotary knob 81 and a gear 83 are fixed to the same shaft 85, and both ends of the shaft 85 are rotatably supported by a substantially U-shaped rotating arm 87. Here, support projections 89, 89 project from both end surfaces of the rotating arm 87, and projections 91 project from the center side thereof. The support projections 89, 89 are provided at positions displaced from the shaft 85 in parallel by a predetermined distance. A pressing portion 93a of a push button switch 93 is provided at a position facing the projection 91.
A resin belt 95 is wound between the gear 83 and the shaft 97 of the rotary switch 96. The supporting projections 89 of the rotating arm 87 are rotatably supported by a main body (not shown), and a push button switch 93 is also fixed to the main body. Further, the rotating arm 87 is pressed by a resilient means (not shown) from the direction of arrow a in the figure with a predetermined resilient force.

When the rotary knob 81 is rotated, the rotational force is transmitted to the shaft 97 via the shaft 85, the gear 83, and the belt 95.
And the on / off state of the rotary switch 96 is changed.

On the other hand, when the rotary knob 81 is pressed in the direction of arrow c, the support projections 89, 89 supported by the main body and the shaft 85
Since the distance is shifted in parallel by a predetermined distance, the rotating arm 87 rotates about the support projections 89, 89, and the projection 91 moves in the direction of arrow d shown in FIG. Is pressed to turn it on.
At this time, since the gear 83 moves with the movement of the shaft 85, the distance between the gear 83 and the shaft 97 of the rotary switch 96 slightly changes. However, the displacement is absorbed by the expansion and contraction of the resin belt 95. You.

When the pressing of the rotary knob 81 in the direction of arrow c is released, the rotating arm 87 is returned to the original position by the elastic force in the direction of arrow a by the elastic means (not shown).

[0008]

However, the above conventional example has a problem that the structure is complicated and the number of parts is large, so that not only the assembling becomes difficult but also the manufacturing cost increases.

The present invention has been made in view of the above points, and an object of the present invention is to provide a rotary electronic component with a push button switch which has a simple structure, a small number of components, and is easy to assemble.

[0010]

In order to solve the above problems, the present invention provides a base 33 on which a rotary electronic component (rotary switch 30) is mounted and a pressing portion 337 is provided.
A mounting plate 10 that rotatably supports the base 33 about a predetermined position thereof; and a base plate 33 that is rotated with respect to the mounting plate 10 by pressing the rotary electronic component. A rotary electronic component with a push-button switch (rotary switch 1 with a push-button switch) is provided by including a push-button switch 50 disposed at a position where the pressing portion 337 of the base 33 is pressed to turn on and off.

[0011]

When the rotary electronic component is rotated, the rotary electronic component can be operated. On the other hand, if the rotary electronic component is pressed,
The base 33 rotates around the point where the base 33 is pivotally supported on the mounting plate 10 together with the rotary electronic components, and the pressing portion 337 turns on the push button switch 50. When the pressing is released, the base 33 returns to the original position, and the push button switch 50 is turned off.
