1. Field of The Invention
The present invention relates to an elastic apparatus for a keyswitch key in a keyboard, and particularly to an elastic apparatus which can be easily positioned in the keyswitch key of the keyboard without resulting in unwanted displacement or inclination thereof with respect to a horizontal base of the keyswitch key.
2. The Prior Art
Keyboards are the most popular input devices for personal computers. Each key of a conventional keyboard generally has a cap connected to a scissors-like mechanism and an elastic device for generating a resilient force during clicks. Generally, conventional elastic devices may be classified into spring-type and rubber-type structures. The spring-type structure is commonly used in the keyboard of a desktop computer. However, the spring-type structure can not satisfy the trend of the PC market toward increasing compactness due to the requirement of at least a minimum length of the spring to exhibit a sufficient resilient force for recovering the keyswitch key back to its undepressed status after manual release there. The rubber-type structure was introduced to overcome the minimum length limitation of the spring-type structure. Although the conventional rubber-type structure meets the compactness requirement, the keyswitch thereof is prone to declination or displacement during clicks. Moreover, most of the present keyswitch keys will generate noise during clicks thus affecting a user's concentration.
Therefore, it is requisite to provide an improved structure of the elastic device for the keyswitch key and a new keyswitch key which can reduce the noise during clicks into a minimum level.
