Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary electronic component with a push button switch.

[0002]

2. Description of the Related Art Conventionally, rotary electronic parts with push-button switches have been used as operating devices for various electric devices such as audio devices. This type of rotary electronic component with a push button switch rotates a rotary electronic component (for example, a rotary encoder) by rotating a knob,
On the other hand, the push button switch is turned on / off by pressing the knob in the rotation axis direction. Then, for example, by rotating a knob, a desired mode (for example, AM, F
M, CD, etc.) is selected, and then the knob is pressed in the direction of its rotation axis to utilize the mode.

[0003]

However, the conventional rotary electronic parts with a push button switch have the following problems.

[0004] Since one knob is turned to operate the rotary electronic component and at the same time press the knob to turn on and off the push button switch, it is possible to rotate the knob while pressing a finger on the surface of the knob. In such a case, the user may accidentally push the knob, thereby causing an unintended on / off operation. On the other hand, in order to prevent such an erroneous operation, it is necessary to increase the pressing pressure for turning on and off the push button switch. However, in that case, the pressing feeling is deteriorated.

A rotary electronic component with a push button switch is usually configured so that the push button switch is turned on and off by pressing the center of the knob. However, since the knob rotates, a desired pressing mark is provided at the center thereof. If you print something like this, it will also rotate. For this reason, the mark needs to be a 360-degree symmetric mark such that its shape does not change even when rotated, which hinders the freedom of mark selection.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object to optimize the operational feeling of a rotary electronic component and a push-button switch separately and independently. An object of the present invention is to provide a rotary electronic component with a push button switch in which a mark does not rotate.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention comprises a substrate, a rotator disposed on the substrate, and an electric function unit for changing the output of the rotator by rotating the rotator. In the rotary electronic component provided, a push rod for a push button switch is attached so as to penetrate the rotating body and the substrate, and a push button switch is disposed at a lower end of the push rod on the lower side of the substrate, and the push rod is provided. The push button switch is configured to be turned on and off by being pressed. It is preferable that the rotary electronic component with the push button switch is provided with means for stopping rotation of the push rod.

Accordingly, the ON / OFF pressing force of the push button switch 110 by the push button 110 can be set as an optimum pressing force to improve the operational feeling.

In this embodiment, the pressing portion 91 of the push rod 90 (see FIG. 4) and the substrate 1 through which the pressing portion 91 penetrates are provided.
Since each of the 0 through holes 17 (see FIG. 2) is formed in an oval shape, the push rod 90 does not rotate. For this reason, even if the rotary knob 100 is rotated, there is no possibility that the push button 110 will rotate with it.

Although the embodiment of the present invention has been described in detail, the present invention is not limited to the above embodiment, and various modifications such as the following are possible.

In the above embodiment, an example is shown in which a metal plate is insert-molded in a mold resin as a substrate. However, it is needless to say that the substrate may be of various other forms such as a flexible substrate. Needless to say, the pattern may be of various other shapes, and may be a resistor pattern. In addition, a slider may be attached to the substrate side, and a pattern may be provided on the rotating body side. Further, an electrical function unit having another structure may be used. In short, any structure may be used as long as it has an electrical function unit that changes the output by rotating the rotating body.

In the above embodiment, since the push rod 90 is made of metal, the insulating sheet 61 is interposed between the push rod 90 and the click contact plate 60. However, either the push rod 90 or the click contact plate 60 is made of an insulating member. If so, the insulating sheet 61 is unnecessary. However, also in this embodiment, since the push button 110 is made of an insulating material, the insulating sheet 61 is not always necessary.

In the above embodiment, the pressing portion 91 of the push rod 90
And the through hole 17 of the substrate 10 is formed in an oval shape, that is, a non-circular shape, so that the rotation stopper of the push rod 90 is configured.
It goes without saying that various other structures may be considered as the push rod rotation stopping means. Further, the through hole 17 constituting the rotation stopping means does not necessarily need to be provided in the substrate 10 and may be provided in another member.

[0033]

As described in detail above, the present invention has the following excellent effects. Since the pushbutton switch is turned on / off by a push rod completely different from the rotating body, there is no possibility that the pushbutton switch is turned on / off by mistake while rotating the rotating body. Therefore, it is possible to optimize the operation feeling of the rotary electronic component and the push button switch separately and independently.

The push rod does not rotate because the push rod rotation stopping means is provided. Therefore, even if the rotating body is rotated, there is no danger that the push rod rotates with it. Therefore, even if a desired mark is printed on the push button attached to the push rod, the mark does not rotate and the mark does not reverse, so that the mark can be formed in a desired shape without any limitation. .
