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.

In conventional push button devices, separate push button bodies of the same shape were often attached side by side if they had the same function.

That is, a guide piece is attached to the inner surface of the cabinet, and an independent push button body guided by each square hole of the guide piece is made to protrude from an opening provided in the cabinet, while a printed circuit board disposed inside the cabinet. Each of the upper button switches was arranged to face each of the push button bodies.

Problems to be Solved by the Invention However, in the conventional configuration, an independent push button body must be attached to each guide square hole of a guide piece, which makes assembly of the push button body into a cabinet difficult and costly. It also had the problem of being expensive.

In view of the above problems, the present invention provides a push button device that is easy to assemble and is inexpensive. .

Means for Solving the Problems In order to solve the above-mentioned problems, the push button device of the present invention has an arbitrary number of push button bodies integrally attached to one end of a guide piece that is disposed on the inner surface of the cabinet and guides an arbitrary number of push button bodies. The present invention is characterized in that an elastic piece is formed and a push button part is integrally formed at the tip of the elastic piece, and the push button part is configured to protrude from the opening hole of the cabinet.

According to the above-described structure, the present invention simplifies the assembly of the push button by integrally providing an elastic piece at one end of the guide piece for guiding the individual push button bodies, and providing the push button part at the tip of this elastic piece. And it is possible to aim at cost reduction.

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

FIGS. 1 to 3 are diagrams showing an embodiment of the present invention, and FIGS.
In Fig. 3, 1 is the main cabinet, 2 is a cassette lid rotatably attached to the main cabinet, 3 is a panel provided on the cassette lid 2, 4 is a tuning operation button, and 5 is a memory operation button for presetting. , 6 are tuning stop operation buttons, 7-1 to γ-6 are preset operation buttons, and these 4 degrees of operation re, s, -r-1 to 7-6 are attached to the cassette lid. There is. A push button guide piece 8 is integrated with the inner surface of the cassette lid 2, and has square holes for guiding the operation buttons 4, 5, and 6, respectively.

Elastic pieces 8-1 to 8-5 are integrally formed at one end of this guide piece 8, and preset operation buttons 7-1 to 7-6 are provided at the tips of these elastic pieces 8-1 to 8-5. The push button part is integrally formed. Reference numeral 9 denotes a rubber member, which together with the printed circuit board 11 constitutes a plurality of bushing switches 1o corresponding to the operation buttons 4, 5, 6, 7-1 to 7-5. That is, the bushing switch 1o includes a rubber molded into a truncated cone shape so as to have elasticity, and a contact piece made of conductive rubber provided in the truncated cone-shaped recess of the rubber is attached to a conductive foil on the printed circuit board 11. It is designed so that they face each other. 12 is a liquid crystal display board that serves as a frequency display indicator.

The guide piece 8 is attached to the inner surface of the cassette lid 2, so that the push button parts 7-1 to 7-1 at the tips of the elastic pieces 8-1 to 8-6
7-6 are square holes 13-1 to 13- provided in the cassette lid body 2.
Operation buttons 4, 5.6 are projected from the openings of the cassette lid body 2 and are guided by square guide holes of the guide pieces 8.

In this embodiment, the tuning operation section for radio reception is concentrated on the front part of the cassette lid 2 fixed to the main cabinet 1, and when the tuning operation button 4 is pressed, the frequency changes and the desired number is set. When the frequency reaches that station, press the stop operation button 6 and the station will be fixed. Next, when the memory operation button 5 and preset button 7 are pressed simultaneously, the preset is completed.

The memory operation button 5 and preset operation button 7 are always pressed by a bushing switch 10 so that they protrude from the surface of the cassette lid 2. In addition, memory operation button 6
has a structure in which it is guided by a square hole in the guide piece 8 and moves upward and downward. When the preset operation button 7 is pressed, the preset operation button 7 is deformed by the elastic pieces 8-1 to 8-5, and the conductive rubber 14 provided inside the bushing switch 10 is deformed by the elastic pieces 8-1 to 8-5.
The conductive foil on the printed circuit board 11 comes into contact with the printed circuit board 11, and the electric circuit is switched.

Effects of the Invention As described above, the present invention provides an arbitrary number of elastic pieces integrally provided at one end of a guide piece for an arbitrary number of push button bodies guided by square holes, and a push button body at the tip of the elastic piece. Since it constitutes a part, it is possible to reduce the number of man-hours when assembling the push button body, and to reduce costs by integrating the lead part, which is extremely effective in practical terms.
