Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is applicable to electronic devices such as computers, electronic calculators, or typewriters. Regarding the cover of the mounted key switch group.

0002

[Conventional technology]

Conventionally, key switches for this type of electronic equipment, etc. Display symbols such as characters or symbols for operation are printed on the top surface.

0003

[Problem that the idea aims to solve]

In the conventional key switch described above, the operator's finger does not touch the key switch directly. Because of this, the top surface of the key switch is likely to get dirty, making it easy for the operator to make incorrect operations. resulting in disadvantages. The present invention was developed in view of the above-mentioned drawbacks of the conventional technology, and its purpose is to Koro has a key switch that makes it easy to see the displayed characters at all times and reduces key switch operation errors. The aim is to provide a ticover.

0004

[Means to solve the problem]

In order to achieve this purpose, the key switch cover according to the present invention is suitable for electronic equipment. A cover that covers the entire key switch group that is installed and does not have a display symbol on the top surface. The entire body is made of soft, transparent plastic or silicone alloy plastic. The operating section is operated by pressing from above the key switch of the electronic device. It is formed into a convex shape by heating in accordance with the position of the switch, and the back surface of the operating section is The display symbol is printed on the .

[0005]

[Effect]

With this invention, fingers do not touch the display symbols directly, and the operation surface is dirty. If the displayed symbols become difficult to distinguish, remove the dirt with a cloth or clean the keypad. Replace the switch cover.

【Example】

The present invention will be explained below based on an embodiment shown in the figure. In Figure 1, the present invention The key switch cover 1 is made entirely of soft and transparent plastic or silicone. It is made of Recon alloy plastic material and has a thickness of approximately 20 to 30 mm. This key switch cover 1 is made of a plastic material that is considered to be a plasticizer. Display symbols consisting of letters and codes are printed on the back side, and then heat is applied to the front side. The operation part 11 which is a convex body and the recess which connects the operation part 11 to the part corresponding to the symbol A shaped connecting portion 12 is integrally formed. Also, the key switch cover 1 itself is not conspicuous. For example, it is colored red, yellow, or blue. The key switch of the keyboard 2 directly below the operating part 11 of this key switch cover 1 21, and fit the key switch cover 1 to the keyboard 2. put it on top.

[0007] The operation will be explained below. 3 and 4, each key switch 21a, 21 From the state where the operation parts 11a, 11b and 11c are placed on b and 21c, When the upper surface 111a of 11a is pressed downward, the key 21a located below it is pressed down. It operates by being pushed towards the side. At this time, both operation parts 11a, 11b and 11c Since the recessed connection portion formed on the side acts as a support, the adjacent key switch 21 b and 21c will not malfunction.

[0008]

[Effect of the idea]

As explained above, according to the present invention, the back side of the operating section of the key switch cover Since the display symbol is attached, your finger does not come into direct contact with the display symbol, so you can easily It is possible to always provide good operating conditions without dirt adhering to the The effect is that the operator can perform operations more efficiently because there is no possibility of erroneous operation. There is.
