A notebook computer is provided with a collapsible keyboard structure in which, in response to closing of the computer housing lid, the key return spring portions of the keyboard are shifted horizontally away from their normal underlying relationships with the keys and the keys are forcibly retracted downwardly to a storage/transport orientation in which the overall vertical thickness of the keyboard structure is reduced by an amount somewhat greater than the stroke distance of the keys. Each key has a relatively rigid top side portion with a periphery around which is secured a downwardly and horizontally outwardly sloped resilient skirt structure. In response to the forcible downward movement of the keys to their retracted positions the skirt structures are pressed and vertically compressed against a bottom side portion of the monoblock member that operatively carries the keys, thereby reducing the vertical height of the keyboard by more than the normal stroke distance of the keys when the computer is in its closed storage and transport orientation. When the lid is subsequently opened, the key return spring portions are upwardly shifted back to their normal underlying relationships with the keys, and the keys are forced upwardly by the return spring portions to their extended, operative orientations above the return spring portions. <IMAGE> |
