PURPOSE:To increase the operability for the key input, by shifting a printed base board that supports the key top to the appearance face of keyboard and accordingly controlling the height of the key top to the said appearance face. CONSTITUTION:Plural holes 1a are arrayed on an appearance face (key panel) 1 of a key board, and a key top 3 is set opposite to each hole 1a. The key top 3 is supported on a printed base board 2 via a block 3a made of conductive rubber, etc. The board 2 is turned round a shaft 7, and a controller 5 is fixed to the other end of the board 2. The height of the top 3 is controlled to the face 1 by adjusting a fine adjustment knob 4. In other words, the board 2 turns round a fulcrum 7 by pulling forward the knob 4 to move close to the face 1. Thus the top 3 is moved to a higher position. |
