Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a push button device that can be used in a channel selection device for a television receiver.

Conventionally, there have been preset type channel selection devices that use multiple switches and select a channel by pressing one of the switches. In this method, the switch lever of a multiple switch is often a general-purpose product, so from a design point of view, a separate button is placed over the lever, and the head of this button is made to protrude outside through the opening in the cabinet. Tuning operations were performed by pressing the top of the button from outside the cabinet.

A conventional push button device is shown in FIGS. 1 to 3. In the figure, reference numeral 1 denotes a multiple switch, which has a plurality of switch levers 2, and is electrically and mechanically connected and fixed to a printed circuit board 3. Each of the switch levers 2 is covered with a button 4, and the head of the button 4 is projected to the outside through an opening provided in the cabinet 5. A display plate 6 made of aluminum or the like is provided on the front side of the cabinet 5 to display the operation of the button 4. Since the switch 1 is of a multiple type, when one pole (button) is pressed, the other poles are unlocked and returned to their original state. Therefore, 1 in Figure 3
When one button 4 is pressed, this button 4 is locked in the pressed state and the degree of protrusion is smaller than the other buttons. I tried to identify whether it was a channel or not.

In such a push button device, the present invention uses a multiple switch similar to the conventional one, provides a button shape integrally in a part of the cabinet, and distinguishes the selected channel display by the degree of protrusion of the button. Without,
This allows for easy identification using a display element such as a light emitting diode.

An example of this will be described below with reference to FIGS. 4 to 6. The figure is similar to FIG. 1 in that a multiple switch 1 is used and that a printed circuit board 3 is attached to the multiple switch 1. Reference numeral 10 denotes a button leg, which has an inverted U shape and is provided integrally with the plastic cabinet 5 so that both free ends thereof are joined to the plastic cabinet 5, and which corresponds to each lever 2 of the multiple switch 1. Multiple pieces are formed. The rectangular projecting piece 11 is attached to the button leg 1 so as to extend further upward from the curved part of the button leg 10.
0. Furthermore, button pieces 12 and 13 are integrally provided on this projecting piece 11 so as to project vertically from both sides thereof. At this time, one button piece 12 projects outward from the opening in the display panel 6 provided in the cabinet 5, and the other button piece 13 comes into contact with the lever 2 of the multiple switch 1. Further, this button leg portion 10 has elasticity, and therefore the button pieces 12 and 13 at the tip end thereof are elastic.
is swingable in the direction of the arrow. Therefore, by pressing one of the button pieces 12, one of the multiple switches 1 is locked and the switch operation becomes possible. Therefore, since the button pieces 12 and 13 are integrated with the button leg 10 as described above, when the pressing force on the button piece 12 is released, it returns to its original position. It is not possible to check the selected channel. Therefore, in this example, the light emitting diode 14 is used as the display element, and the printed circuit board 3
The light emitting diode 14 can be seen from the front side through the central space of the button leg 10. This is also one of the reasons why the button leg 10 is shaped like an inverted U. The lighting state of the light emitting diode 14 can be ensured from the outside of the cabinet through an aperture provided in the display panel 6 or a transparent portion 15 covering the aperture from the central space of the button leg 10.

According to this configuration, without using a separate button,
By integrally providing the button leg portion 10 and the button pieces 12, 13 on the cabinet 5, a general-purpose multiple switch number can be operated, and the channel selection can be confirmed using a light-emitting display, improving operability. In addition, although the above-mentioned example explained the case where it is used for a channel selection device, it is not limited to this.

As described above, according to the present invention, an inverted U-shaped button leg is integrally provided in the cabinet, and a first button piece facing a switch lever and a second button leg for operation are integrally formed on this button leg. By providing a button piece, a switch operation can be performed without providing a separate button, improving operability. Further, since the operation display is a light-emitting display, confirmation can be easily performed.
