Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an operating pushbutton device, and more particularly to an operating pushbutton device suitable for audio equipment, particularly tape decks and the like.

The operation push button device is used in audio equipment such as a cassette tape deck, and a typical example is shown in FIGS. 1 and 2.
That is, the upper ends of each of the operation buttons 1, 2, and 3 are connected by a horizontally horizontal connecting piece 4, and a projection 7 protruding from the back side of the operation panel corresponds to a small hole 5 formed in the connecting piece 4. The ends of the protrusions 7 are melted and fixed by caulking, and the locking claws 1a, 2a, 3a formed at the lower end of each operation button are attached to the edge of the mounting hole 6a of the operation panel 6 on the back side. It's starting to hit me. Each of the operating buttons 1, 2, and 3 has operating protrusions 1b, 2b, and 3b at the center of the back side, and these operating protrusions can operate an operating switch 8 such as a tact switch.

In such an operation push button device, the various operation buttons 1, 2, and 3 are connected to each other, so if even one of them is defective or damaged, all the operation buttons will be replaced. In addition, during assembly, it is necessary to weld the protrusions 7, and in addition, when plating is applied, masking must be performed on the 4 parts of the connecting piece that has the hinge function, which is a hassle during manufacturing and assembly. This is a cumbersome configuration.

Therefore, this invention is an attempt to solve the above-mentioned problems in manufacturing and assembling the conventional operation pushbutton device.For this purpose, it is possible to drill a mounting hole in the operation panel, and also to A pushbutton support piece is formed integrally with the operation panel so as to face each other, and the pushbutton is sandwiched and supported between the operation panels by the elasticity of the pushbutton support piece.

The configuration of this invention will be explained below with reference to the embodiments shown in FIGS. 3 to 7. First, in FIGS. 3 and below, reference numeral 10 indicates an operation panel. This operation panel 10 has a push button mounting window hole 11, and a push button is inserted into the back side of the operation panel 10 so as to fit through this mounting window hole 11. A button support piece 12 is integrally formed therewith. This push button support piece 1
2 is formed by two horizontal pieces 12b, 12b perpendicular to the vertical pieces 12a, 12a on both sides, and each end 12 of the vertical pieces 12a, 12a
c has an L-shaped bent shape and is integrated with the operation panel 10.

The push button 20 has locking hooks 22 and 23 formed at both upper and lower ends of the flat surface portion 21, respectively, to be locked on both upper and lower sides of the mounting window hole 11 of the operation panel 10. Reference numerals 22 and 23 are located at the center portion in the width direction of the surface portion 21 of the push button 20, and the shape is such that an operation protrusion 24 is formed on the back side of the surface portion 21.

At the back of the operation panel 10 is a tact switch 31 attached to a board 30, and a push button 20.
The tact switch 31 can be operated by pushing the button.

Next, the assembly and operation of the operation push button device according to this invention will be explained. First, the pushbutton 20 is pushed into the mounting hole 11 made in the operation panel 10, and the locking hooks 22 and 23 formed on the pushbutton 20 are attached to the operation panel 10.
It is now locked on the back side of the locking hook 2.
Vertical pieces 12 of push button support pieces on both sides of 2 and 23
a, 12a are located, a pushing force is applied from the back side of the push button 20 toward the front side, and furthermore, the operation protrusion 24 is pressed against the vertical pieces 12a, 1 of the push button support piece 12.
It protrudes from the space surrounded by horizontal pieces 12b and 2a, and its operation protrusion 24 pushes the tact switch 31.

The pushbutton 20 is inserted into the mounting hole 11 of the operation panel 10.
By attaching the push button support piece 12 to the push button 20, the push button support piece 12 is slightly pushed in, but this elastic deformation becomes a force that urges the push button 20 in the projecting direction.

Therefore, when you press the push button 20 with your fingertip,
The pushbutton support piece 12 is pushed and deformed against its elasticity, and the operating protrusion 24 operates the tact switch 31. When the force on the push button 20 is removed, the elasticity of the push button support piece 12 causes the push button 2 to
0 is returned to its original position.

As is clear from the above description, the operation pushbutton device of this invention allows the operation panel to have a mounting hole for the pushbutton, and is located opposite to the mounting hole with a slight gap between the operation panel and the pushbutton. A push button support piece is integrally formed on the back side, and locking hooks that can be locked to the edges of the mounting hole of the operation panel are provided at both ends of the push button, so that the push button support piece and the operation panel are provided with locking hooks. Since the pushbuttons are configured in a sandwiched manner, each pushbutton is independent and can be assembled by simply pushing each pushbutton into the mounting hole of the operation panel.
In addition, the push button can be easily formed.
