Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a push button device for electronic equipment such as radio receivers and tape recorders.

2. Description of the Related Art In recent years, feather-touch push button devices have been increasingly used as switch devices for audio equipment such as radio receivers.

An example of a conventional switch push button device will be described below with reference to the drawings.

FIG. 6 shows a conventional push button device. In Fig. 6, 1 is a cabinet, 2a and 2b are push button bodies, and 3 is a push button body 2J.
Guide pieces 4a and 4b guide the push button bodies 2a and 2b, and 6 is a printed circuit board on which tact switches 4L and +b are mounted. Guide piece 3
push button bodies 2N, 2b each independently guided by
are provided protrudingly, and tact switches 41L, +b on the printed circuit board 6 are associated with these push button bodies 2IL, 2b.

In such a configuration, when one of the push buttons 21 protruding from an opening provided in the cabinet 1 is pushed in, the tact switch 4& provided in the printed circuit board 5 is operated and the electric circuit is switched. Next, when the other push button 2b is pressed, the tact switch 4b is operated and the circuit is switched to another electric circuit.

Problems to be Solved by the Invention However, with the above configuration, two push button bodies and two tactile switches are required, resulting in a cost increase.

In view of the above-mentioned problems, the present invention provides a push button device that can switch two switches with one push button body, is easy to operate, and can be made at low cost.

Means for Solving the Problems In order to solve the above-mentioned problems, the push button device of the present invention includes push buttons arranged in parallel on a printed circuit board housed in a cabinet, and push buttons arranged so as to face each of the push switches. The push button body is disposed in the opening hole of the cabinet and is capable of see-saw movement using a horn provided around the periphery as a fulcrum.

Function: Due to the above-mentioned function, when the right half or the left half of the push button body is pushed in, the push button body moves as a seesaw using the collar part on the side farther from the part to which the pressing force is applied as a fulcrum. The seesaw movement causes the push switches arranged in parallel on the printed circuit board to be pressed. As a result, two switches can be switched with one push button body, making it easy to operate and inexpensive.

EXAMPLE Hereinafter, a push button device according to an example of the present invention will be described with reference to the drawings.

1 to 3 show embodiments of the present invention. Figures 1 to 3
In the figure, 11 is a main body cabinet, 12 is a cassette lid rotatably attached to the main body cabinet 11,
Reference numeral 13 designates a panel of the cassette lid book 12, which is made of transparent plastic. 14 is a tuning operation button, 1
5 is a stop operation button, 16 is a liquid crystal display whose dots change according to the frequency, 17 is an operation button for a mechanism built into the main body cabinet 11, and 18 is a switch for changing between radio and tape.

Here, the tuning operation button 14 protrudes from an opening hole 122L provided in the cassette lid body while being guided by the guide piece 19, and the collar portion 141L around the opening hole 122L comes into contact with the inner surface of the opening periphery of the guide piece 19. ing. The cassette lid body 1 is provided on the bottom surface of the tuning operation button 14.
Push switches 251L and 25b are arranged in parallel on the printed circuit board 21 housed in the push switch 4 and are opposed to each other.

The push switches 251L, 25b include a rubber 20 formed into a truncated cone shape so as to have elasticity, and a contact piece 24 made of conductive rubber provided in a truncated cone-shaped recess of the rubber 20 is placed on a printed circuit board 21. The truncated cone-shaped convex portions 23 arranged in parallel with the rubber 20 are arranged to face a conductive foil serving as a switch contact piece, and are adapted to abut on the lower surfaces of the tuning operation buttons 14, respectively.

In other words, the right half of the tuning operation button 14 is for up,
The left half is for down, and these halves have push switches 251L and 25b arranged side by side on the printed circuit board.
are associated with each other. Note that 22 is a liquid crystal display board mounted on a printed circuit board.

In such a configuration, when the left half of the tuning operation button 14 is pressed as shown in FIG. The tuning operation button 14 rotates about the fulcrum, and the push switch 26a is suppressed. In other words, when the tuning operation button 14 is tilted to the left, the protrusion 23 of the rubber 20 placed under the tuning operation button 14 is bent, and the contact piece 24 made of conductive rubber, which is integrally provided inside the protrusion 23, is bent to the printed circuit board. Contact with 21. At this time, the electric circuit is switched and the liquid crystal display section 1
The dot number 6 moves toward the higher frequency. Similarly, when the other side of the tuning operation button 14 is pressed, the tuning operation button 14 tilts to the right as shown in FIG. 6, the push switch 25b changes, and the dots on the liquid crystal display 16 move toward the lower frequency side. To go.

As described above, according to this embodiment, the switches are arranged in parallel by disposing rubber pieces formed in the shape of elastic truncated cones and having contact pieces partially made of conductive rubber on the printed circuit board. The push button body provided at a position corresponding to the switch arranged in parallel is configured to be able to move in a seesaw manner, and when one side of the push button body is pressed, the switch is activated and the electric circuit is switched.
It can be constructed so that pressing the other side switches to another electrical circuit, and one pushbutton body can switch between two circuits.

In the embodiment, a tuning operation button is provided on the cassette lid, but it goes without saying that the cassette lid constitutes a part of the cabinet.

Effects of the Invention As described above, the present invention associates a scene-movable push button body with a collar portion as a fulcrum with push switches arranged in parallel on a printed circuit board, so that when one side of the push button body is pressed, the switch is activated. To realize a push button device in which the working electric circuit is switched, and when the other side is pressed, the switch is activated and a different electric circuit is made to work, thereby making it possible to switch two electric circuits with one push button body. be able to.
