According to a fourth aspect of the present invention, there is provided the luminous keyboard according to the first aspect, wherein the luminous body is electrically connected to or disconnected from a work power supply by turning on and off the key.

[0007]

[Embodiment of the invention]

 According to the present invention, the illuminated keyboard is provided with at least one kind of space inside the base of the keyboard on which the key group is installed, at the space at the bottom of the key top of each key or at the space at the bottom of the key top of the special key. A color light source is provided, the keytop is transparent or translucent, the light source is a light emitter of a different form, and the electrical contacts of the light emitter conduct to the substrate in the base of the keyboard, and the light transmission of the keytop is performed. Utilizing the characteristics, the keys of the keyboard display different colors by the light emitted from the light source, display different function information, and form a variety of beautiful keyboard appearances.

[0008]

【Example】

 As shown in FIGS. 1 and 2, the illuminated keyboard 10 of the present invention has a space located at the bottom of the key top 13 of each key 12 inside a keyboard case 11 having a key group on the surface. Alternatively, at least one type of color light source is provided in a space at the bottom of the key top 13 of the special key.

The above-mentioned key 12 has a convex column 14 extending downward from the bottom surface of the upper wall of the key top 13, and the bottom end of the convex column 14 is connected to the elastic body 15, and the bottom edge of the elastic body 15 A conductive contact is provided on the substrate 16 so as to correspond to the substrate 16, and the key top 13 vertically moves through the elastic body 15 to trigger the electrical contact of the substrate 16.

The above-mentioned key top 13 is made of a material that becomes transparent or translucent after molding, is made transparent or translucent, and has a light transmitting property.

The above-mentioned color light source is a light emitting body 20 of various different forms, for example, an LED, and electrical contacts of the light emitting body 20 are electrically connected to a board 16 inside the keyboard to provide a necessary work power. You.

In an actual application, the installation position of the light emitter 20 is determined according to actual needs. For example, a luminous body 20 is provided at the bottom of each one of the keys 12 of the keyboard 10 so that each of the keys 12 has a luminous display function, or a key top 13 of a special key. A luminous body 20 is provided at the bottom, and the special key has a luminous display function.

As shown in FIG. 2, the illuminant 20 is installed in the bottom space of the key top 13, and light is introduced by the transparent or translucent key top 13, or a key on the inner edge of the key top. The light from the light emitter 20 is displayed directly in the interior space of the top 13 or the light emitter 20 is fixed to the inner wall surface of the key top 13 and transmitted through the key top 13.

The number of light emitters 20 can be changed as needed. It is possible to display only a single color light by displaying only a single light emitting body 20 at the bottom of the key top 13, and to perform various kinds of color light emitting display by installing a plurality of light emitting bodies 20. .

There are many types of conduction between the luminous body 20 and the power supply end. For example, conduction and disconnection of the luminous body 20 and the working power supply through the on / off of the key, or on / off control of the key Regardless, the DC power supply of the wireless keyboard or through a cable to the computer provides power to the computer so that the keyboard emits light when a key is pressed or turns off when a key is pressed. Achieve the function.

[0016] The above-mentioned related circuit for continuity between the luminous body and the power supply, and the normally open and normally closed electric connection circuit are not the targets of the claims of the present invention, and are circuits already found in general electronic devices. The description is omitted.
