Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an operating device for electronic equipment equipped with a push button switch and a variable resistor for operating the electronic equipment.

[Conventional technology]

Conventionally, operation buttons and the like for operating electronic devices such as televisions and video devices have been attached to the operation panel portion of the surface of the electronic device, or have been attached to the surface of a remote control device that operates this type of electronic device using infrared rays. It had been installed.

This type of operation panel or remote control device is equipped with a synthetic resin board on which a circuit pattern is formed and various electronic components are attached to the inner surface of a synthetic resin case, and a push button or rotary variable resistor is installed between the case and the board. It is constructed by arranging the containers and the like and pasting a metal decorative board on the surface of the case.

The electronic device is operated by operating the push buttons, rotary variable resistor, etc. from the front side of the case.

[The problem that the idea aims to solve]

However, in the case of such a conventional operating device for an electronic device, it is necessary to attach a metal decorative plate to the upper surface of the case, resulting in a problem that the number of parts increases.

In addition, in the case of an operating device with a structure in which operation buttons are attached to both sides, the structure becomes even more complicated because decorative plates are attached to both sides, and the number of parts increases, making it difficult to make it smaller and thinner. .

Furthermore, since the case and the board are made of synthetic resin, there is a problem in that heat generated by various electronic components tends to accumulate inside them.

The present invention has been made in view of the above points, and provides an operating device for electronic equipment that can reduce the number of parts, has a simple and thin structure, and can easily dissipate heat generated inside the operating device. It's about doing.

[Means to solve the problem]

In order to solve the above problems, the present invention has developed a resistor pattern in which a slider is in sliding contact with the back surface of a metal exterior plate,
A circuit pattern having contact portions for turning on and off switches was formed, and a variable resistor, a push button switch, etc. were arranged on the surface on which various patterns were formed, thereby constructing an operating device for an electronic device.

[Effect]

By configuring the operating device for electronic equipment as described above, the metal plate itself is used as an exterior plate, a circuit pattern is formed on the back side of the metal exterior plate, and a slider is attached to this circuit pattern on the back side. Since we have placed a variable resistor that slides into contact with the switch and a push button switch that turns on and off the contacts of the circuit pattern, this metal exterior plate serves as a board, and a special board for these variable resistors, push button switches, etc. is no longer necessary, which not only reduces the number of parts but also makes the structure thinner.

Further, since electronic components can be directly attached to the circuit pattern provided on the metal plate, the heat dissipation property of the electronic components is improved.

Press 3. As a result, this click spring is reversed, and the contact portion 72 forming part of the circuit pattern on the back surface of the flexible substrate 7 is pressed and comes into contact with the contact portion 22 on the second metal exterior plate 2, turning it on. It is. Note that when the pressure on the push button portion 51 is released, each member returns to its original position and the connection between both contact portions is turned off.

Even if the push button 6 is pressed, the first metal exterior plate 1
The upper contact portion and the contact portion on the flexible substrate 8 are turned on.

Note that 15 attached to the back surface of the first metal exterior plate 1 shown in FIG. 1 is a light emitting element.
