An Introduction to the NMFS Marine Recreational Fisheries Statistics Survey with an Emphasis on Economic Valuation

A keyboard, which may be made very thin and be suitable for notebook computers or personal digital assistants, has a substantially rigid base plate supported for movement between an extended position and a retracted position but biased to the extended position. The keyboard has a plurality of keys and a switch means associated with each key to register when the key has been pressed. When a key is pressed the base plate moves from the extended position to the retracted position, that movement providing for at least some travel of the pressed key. A sufficient degree of travel can be provided that the keyboard, even in a very thin form, can be used for touch-typing.
