Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a direction control key of a controller used for remote control of home electric appliances and game machines.

[0002]

2. Description of the Related Art It is desirable that remote controllers for home electric appliances and game machines be as small and sturdy as possible. FIG. 6 is a sectional view of a direction control key of a remote controller of a conventional game machine or the like. The remote controller forms a case by combining the bottom case 14 and the top case 13, and an opening for a key top is provided in a part of the top case 13, and the top of a key top (plus key top) 15 that can be controlled in four directions. The surface is made to appear on the surface of the top case 13.

A wiring board 16 is supported on the bottom case 14, and the key top 15 on the upper surface of the board 16 is supported.
The rubber switch assembly 17 is arranged at a portion corresponding to. A protrusion 15a is provided at the center of the lower surface of the plus key top 15, and the protrusion 15a contacts the wiring board 16 to form a fulcrum of the plus key top 15. The rubber switch assembly 17 includes four rubber switch contacts 17a,
17a is provided, and one of the rubber switch contacts 17a is compressed by the plus key top 15 to form a circuit.

[0004]

When a game machine or the like is operated by a remote controller, the player pushes the plus key top 15 with a force more than expected during heat, so that the player is provided at the center of the lower surface of the plus key top 15. Protrusion 1
The substrate 16 may be destroyed by 5a. Furthermore, one of the rubber switches 17a of the rubber switch assembly 17 may be compressed more than necessary and may be damaged in an extreme case. Further, it is not preferable that the excessive compression force is repeatedly applied to the rubber switch 17a, even if it is not broken, because it causes fatigue of the rubber switch 17a. It is an object of the present invention to provide a direction control key for a controller, which can solve the above-mentioned problems.

[0005]

In order to achieve the above-mentioned object, the direction control key of the controller according to the present invention is supported so that the direction control key appears on the surface of the top case of the combined case composed of the top case and the bottom case. In a direction control key of a controller that generates a signal for controlling a direction, a key top provided with a flange portion larger than the opening of the top case and a top portion thereof being exposed from the opening, and being supported by the bottom case. A wiring board, a rubber switch assembly provided on the surface of the wiring board so as to correspond to the keytop, and a shaft which penetrates the wiring board and is desired at the center of the keytop and serves as a fulcrum of the keytop. And the limit of the inclination of the key top is that the key top contacts the shaft and the flange contacts the back surface of the top case. It is configured to be defined by Rukoto. The rubber switch assembly is a four-contact switch, and the key top can be a plus key top. The key top may be configured so that the flange of the key top is pressed against the back surface of the top case by the elasticity of the contacts of the rubber switch. A shaft serving as a fulcrum of the key top may be provided integrally with a base that supports the wiring board. A cylindrical portion that surrounds the key top and that directly or indirectly contacts the substrate may be provided on the back surface of the top case.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the direction control key of the controller according to the present invention will be described in more detail with reference to the drawings. FIG. 1 is a plan view of a controller to which an embodiment of a direction control key of a controller according to the present invention is applied. This controller is a controller of a game device, and a plus key top 5 is provided on the left side of the top case 3 and an input key group 8 is provided on the right side of the top case 3, and a remote control signal is forwarded from a front filter (infrared radiation window) 2 in the center. It is designed to be projected on. 2 is a sectional view of an embodiment of the directional control key of the controller according to the present invention in a natural state, and FIG. 3 is a sectional view of an embodiment of the directional control key of the controller according to the present invention in an operating state. 2 and 3 correspond to sectional views taken along the line AA of FIG.

As shown in FIGS. 2 and 3, the plus key top 5 has a flange portion 5a larger than the opening 3b of the top case 3, and the top portion is provided so as to emerge from the opening 3b. The bottom case 4 is provided with a pedestal 4b of the wiring board 6 and a shaft 4a penetrating a hole of the wiring board 6 and forming a fulcrum of the plus key top 5. A rubber switch assembly 7 provided corresponding to the plus key top 5 is provided on the surface of the wiring board 6.

FIG. 4 is a sectional view of a rubber switch assembly used in an embodiment of a directional control key of a controller according to the present invention, and FIG. 5 is a plan view of a rubber switch assembly of an embodiment of a directional control key of a controller according to the present invention. . The plus key top 5 is provided at the center of the rubber switch assembly 7 substrate.
Is provided with a hole 7c penetrating the shaft 4a forming the fulcrum, four rubber switch contacts 7a, 7a ... Are arranged, and a circuit is formed by the printed wiring 7b. The flange 5a of the plus key top 5 is pressed against the back surface of the top case 3 by the elasticity of the contacts 7a, 7a ... Of the rubber switch assembly 7 as shown in FIG.

When the right end of the plus key top 5 is pressed as shown in FIG. 3, the plus key top 5 is moved to the position indicated by the point A in FIG.
The left end side of the flange 5a contacts the back surface of the top case 3, the center of the top case 3 contacts the tip of the shaft 4a as shown by the point B, and the right rubber switch contact 7a is pushed to form a circuit. The inclination limit of the key top 5 is defined by the center of the back surface of the key top 5 contacting the shaft 4a and a part of the flange 5a contacting the back surface of the top case 3.

On the back surface of the top case 3, a cylindrical portion which surrounds the plus key top 5 and indirectly contacts the wiring board 6 through the outer peripheral portion of the rubber switch assembly 7 arranged on the board 6. 3a and structurally reinforced. As described above, various modifications can be made to the embodiments described in detail within the scope of the present invention. The direction control key can be applied not only to the plus key top but also to the two-way key top.

[0011]

Since the direction control key of the controller according to the present invention is constructed as described above, the key top 5 is used.
The limit of the inclination of the key top 5 is that the center of the back surface of the key top 5 is the shaft 4
It is defined by contacting a and a part of the flange 5a contacting the back surface of the top case 3. Therefore, the operation range of the keytop 5 is determined, and the problem that the axis of the keytop excessively pushes the wiring board and destroys the board unlike the directional control key of the conventional controller cannot occur. Also,
Similarly, the rubber switch contacts of the rubber switch assembly will not be crushed excessively. Furthermore, the stroke of the key top can be adjusted by changing the height of the fulcrum shaft 4a. The directional control key of the controller according to the present invention allows the directional control key of the controller to be robustly constructed with a minimum number of parts.
