BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover for a key switch group mounted on an electronic device such as a computer, a computer or a typewriter.

[0002]

2. Description of the Related Art Conventionally, a key switch for an electronic device or the like of this type has a display symbol such as an operation character or a symbol printed on the top surface of the key switch itself of the electronic device or the like.

[0003]

In the above-mentioned conventional key switch, since the operator's finger directly touches the key switch, the top surface of the key switch is easily soiled, which causes a drawback that the operator is likely to make an erroneous operation. . The invention is
The present invention has been made in view of the above-mentioned conventional drawbacks, and an object thereof is to provide a key switch cover in which display characters are always easy to see and an operation error of the key switch is reduced.

[0004]

In order to achieve this object, a key switch cover according to the present invention is a cover that covers the whole of a key switch group that is mounted on an electronic device and has no display symbol on its top surface. That is, the whole is made of soft and transparent plastic or silicon alloy plastic, and the operation part for pressing from above the key switch of the electronic device is formed into a convex body by heating corresponding to the position of the key switch and The display symbol is printed on the back surface of the operation unit.

[0005]

In the present invention, the display symbol is not directly touched by a finger, and when the operating surface is dirty and the display symbol is difficult to distinguish, the stain is removed with a cloth or the key switch is used. Replace cover.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described based on an embodiment shown in the drawings. In FIG. 1, the key switch cover 1 according to the present invention is entirely made of a soft and transparent plastic or silicon alloy plastics material, and has a thickness of about 20 to 30 mm. This key switch cover 1
First, a display symbol consisting of letters and codes is printed from the back side on the plastics material used as a plasticizer, and then by heating, the operation portion 11 and the operation portion 11 which are convex bodies are connected to the portion corresponding to the display symbol. Recessed connecting portion 12
Are integrally formed. Further, the key switch cover 1 itself is colored in a conspicuous color such as crimson, yellow or blue. The key switch cover 1 is put on the keyboard 2 by fitting the operation portion 11 of the key switch cover 1 in correspondence with the key switch 21 of the keyboard 2 directly below.

The operation will be described below. 3 and 4, when the upper surface 111a of the operating portion 11a is pressed downward from the state in which the operating portions 11a, 11b and 11c are covered on the respective key switches 21a, 21b and 21c, the key 21a located therebelow is moved downward. It is pushed into and works. At this time, since the recessed connection portions formed on both sides of the operation portions 11a, 11b and 11c perform a supporting action, the adjacent key switches 21b and 21c do not malfunction.

[0008]

As described above, according to the present invention,
Since the display symbol is attached to the back side of the operation part of the key switch cover, your finger does not come into direct contact with the display symbol,
Since it is possible to always provide a good operation state without stains on the display symbol, and therefore the operator does not make an erroneous operation, there is an effect that an efficient operation can be performed.
