Abstract
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 away from their normal underlying relationships with the keys and the keys are forcibly retracted to a storage/transport orientation in which the overall thickness of the keyboard structure is reduced by an amount essentially equal to the stroke distance of the keys. When the lid is subsequently opened, the key return spring portions are shifted back to their normal underlying relationships with the keys, and the keys are forced outwardly by the return spring portions to their extended, operative orientations above the return spring portions. Incorporated into the collapsible keyboard structure is a cursor position control pointing stick device that is automatically retracted to a collapsed orientation in response to a corresponding collapsing of the keys, and automatically extended back to a use orientation in response to a corresponding return of the keys to their extended use orientations.
