Key Pad Structure of Keyboard and Method for Manufacturing the Same
First Claim
1. A key pad structure of a keyboard, comprising:
- a circuit board having a plurality of through holes;
an elastic portion disposed on the circuit board;
a key cap disposed above the elastic portion; and
a supporting structure, being partially pivoted within the through holes and below the key cap so that the supporting structure allows the key cap to move in a linear up-and-down motion with respect to the circuit board,wherein the circuit board is activated when the key cap moves downward from an initial position, and then the key cap moves upwards so as to return to the initial position from a resilience provided from the elastic portion.

Abstract
The present invention provides a key pad structure for a keyboard. The key pad structure comprises a circuit board, an elastic portion, a key cap and a supporting structure. The elastic portion is disposed on the circuit board that has a plurality of through holes. The key cap is disposed above the elastic portion. Additionally, the supporting structure is partially pivoted within the through holes and below the key cap. The supporting structure allows the key cap to move in a linear up-and-down motion with respect to the circuit board. In detail, when the key cap moves downwards from an initial position, the switch of the circuit board is thus, activated. Then, the key cap moves upwards to return to the initial position from the resilience provided from the elastic portion.
