BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in machines, mechanisms, and the like, which require input by a key, and more particularly, relates to a tilted key input device capable of generating a signal by operating in accordance with a change in tilt.

Conventional key input devices include a keyboard in which keys are simply listed, a mouse for selecting a menu displayed on a monitor, and a joy stick.

However, the present invention uses a different principle from these key input devices, and in addition to the key input means by a general push switch, a conductive ball for rolling an inclined valley or face serves as an electrode to electrically connect or disconnect the conductive plates. It is an object of the present invention to provide a key input device by tilting a switch function.

In the key input device for manipulating a machine, a mechanism, and the like provided with a limb key formed on one side of the handle housing and a thumb key on the upper side of the present invention for achieving the present invention as described above, installed in the handle housing And each of the valleys in the four directions in the center, but has a conductive support plate formed to be inclined so that the valley of the center is relatively lower than the ends, and four sides to surround the conductive support plate at a predetermined interval, and these surfaces are insulated from each other. And a tilt switch composed of a conductive direction plate and a conductive ball electrically connected to or blocking the conductive support plate and the conductive direction plate so as to be mounted on an upper portion of the conductive support plate and move in a tilted manner.

Hereinafter, with reference to the accompanying drawings the technical configuration and preferred embodiments of the present invention will be described in more detail.

1 is a perspective view of a key input device of the present invention.

2 is an exploded state diagram of the components of the present invention.

3a, b, and c are views showing an operating state of the present invention, and 4a, b, and c are shown in a circuit diagram of FIG.

According to the configuration of the present invention, the thumb key 40, which is operated by the thumb large, the limb key 50, which is operated by the four fingers except the thumb, and the thumb key 40 and the limb key 50 are fixed. And a tilt switch 60 installed in the case.

The inclination switch 60 includes a conductive support plate 20, conductive direction plates 30, 31, 32, 33, and a conductor ball 10.

The conductive support plate 20 has each ball in the four directions from the center and the center is formed to be inclined relatively lower than the end of each bone.

The conductive direction plates 30, 31, 32, and 33 are positioned around the conductive support plate 20, and each of them and the conductive support plate 20 are fixed to be spaced apart at predetermined intervals to be electrically connected to each other. Do not connect.

The conductor ball 10 is mounted on the conductive support plate 20 and moved along the valleys or corners by tilting in each direction.

Referring to the operation relationship of the present invention having the above configuration is as follows.

As shown in FIGS. 1 and 2, when the main body of the key input device is lightly gripped, the four fingers and the thumb are positioned on the limb key 50 and the thumb key 40, respectively.

This state is a state in which the conductor ball 10 is not inclined in the center of the conductive support plate 20 having a valley inclined in four directions (hereinafter, divided into east, west, south, and north for convenience) from the center. That is, it is located in the center of the conductive base plate 20.

The state at this time is the same as that of the 3a diagram, and the conductor ball 10 is located at the center where the valleys having the inclination are gathered. It is not neutral.

When the key input device is inclined to the east in the neutral state as described above, the conductor ball 10 rolls along the valley of the conductive support plate 20 and comes into contact with the conductive direction plate 30 to stop.

In this state, the conductive base plate 20 and the east conductive direction plate 30 are electrically connected by the conductor ball 10 so that the switch is closed.

When the key input device is tilted in the same way as the south and north directions, the ball 1 moves to turn on the respective west, south and north switches.

In addition, only one example of having an inclination in the north-east, south-east, north-west, and south-west directions rather than the east, west, south, and north directions will be described below, and thus the remaining directions operate the same.

For example, when the key input device is tilted in the northeast direction as shown in FIG. 3C, the conductor ball 10 moves to an intermediate position between north and east so that the east conductive direction plate 30 and the north conductive direction plate 31 are adjacent to each other. It stops in contact with the edge.

Accordingly, since the conductive base plate 20, the east conductive direction plate 30, and the north conductive direction plate 31 are electrically connected by the conductor ball 10, the tilt of the northeast direction can be detected.

4 is a circuit diagram showing the operating relationship of the present invention shown in FIG.

That is, the size of the tilt at which the tilt switch 60 operates is determined by the slope of the valley of the conductive support plate 60.

Therefore, the operation of each switch may also make the operation according to the inclination in each direction different from the inclination of the valley in the east, south, west, and north directions.

As described above, the present invention has the advantage that it can be utilized as a tilt detection device by installing the switch, the operation of the machine, the operation or mechanism of the mechanism, the moving parts in the machine, etc. by simply operating the switch by simply tilting.
