Keyboard-display combination

Claim 2

A keyboard-display arrangement in combination with a controlled system capable of performing a plurality of system functions, comprising: a flexible screen having extended upper and lower surfaces; a series of keys which are functionally and structurally integral with said screen and disposed in an array, each of said keys being substantially invisible when disabled and visible when enabled at said upper surface of said screen, each of said keys being operative to initiate a particular system function and comprising a contact switch responsive to and actuated upon depression of a corresponding surface portion of said screen, said controlled system being responsive to each of said keys, as selectively actuated, to initiate said particular system function; first means for enabling selected ones of said keys; means for rendering said enabled keys visible at said upper surface of said screen; and second means responsive to said keys, as selectively actuated, for controlling said first means to enable others of said keys operative to initiate other system functions in proper sequence with said particular system function by a selected one of said keys and for disabling remaining ones of said keys.

Claim 3

The keyboard-display combination of claim 1, wherein said rendering means comprises individual lamps corresponding to each of said switches, said lamps being housed within a partitioned cage disposed adjacent said lower surface of said screen.

Claim 4

The keyboard-display combination of claim 1, wherein said surface defines a plurality of illuminative portions corresponding to said keys, each of said keys comprising a label which is visible at said corresponding surface portion when said key is enabled.

Claim 5

The keyboard-display combination of claim 3, wherein said screen comprises a plurality of panels, a first panel defining said illuminative portions, and three contiguous panels comprising said contact switches.

Claim 6

The keyboard-display combination of claim 4, wherein said three contiguous panels comprise two panels comprising conductors and separated by a spacer panel having a plurality of apertures wherein said conductors on said two panels can contact.

Claim 7

A keyboard-display in combination with a controlled system capable of performing a plurality of system functions, comprising: a screen having an extended upper and lower surface; a plurality of keys disposed in an array in close adjacency to said lower surface of said screen, said keys being substantially invisible at said upper surface of said screen when disabled, each of said keys being operative to initiate a corresponding system function, each of said keys comprising an illuminative identification area, said controlled system being responsive to each of said keys, as selectively operated, to initiate said corresponding system function; first means for selectively enabling one or more of said keys in accordance with particular system operations to be performed by said controlled system; means for illuminating said identification areas of said enabled keyes, so as to be visible at said upper surface of said screen; means responsive to enabled ones of said keys, when operated, for controlling said system to perform in said corresponding system functions; and means responsive to said enabled keys, when operated, for controlling said first means to selectively enable others of said keys corresponding to other system functions to be performed in proper sequence with said system function being performed by said system and for disabling remaining ones of said keys.

Claim 8

A keyboard-display in combination with a controlled system capable of performing a plurality of system functions, comprising: a screen having an extended upper and lower surface; a plurality of keys disposed in an array in close adjacency to said lower surface of said screen, said keys being substantially invisible at said upper surface of said screen when disabled, each of said keys being operative to initiate a corresponding system function, each of said keys comprising an illuminative identification area, said controlled system being responsive to each of said keys, as selectively operated, to initiate said corresponding system function; first means for selectively enabling one or more of said keys in accordance with particular system operations to be performed by said controlled system; means for illuminating said identification areas of said enabled keyes, so as to be visible at said upper surface of said screen; means responsive to enabled ones of said keys, when operated, for controlling said system to perform in said corresponding system functions; and means responsive to said enabled keys, when operated, for controlling said first means to selectively enable others of said keys corresponding to other system functions to be performed in proper sequence with said system function being performed by said system and for disabling remaining ones of said keys.

Claim 9

The keyboard-display combination of claim 6, wherein said keys comprise illuminative areas disposed upon said screen.

Claim 10

The keyboard-display combination of claim 6, wherein said plurality of keys comprises a plurality of contact switches.

Claim 11

The keyboard-display combination of claim 8, wherein said contact switches comprise conductors mounted upon panels, said panels being separated by a spacer panel having apertures disposed therein for allowing contact between said conductors.

Claim 12

The keyboard-display combination of claim 6, wherein said illuminating means comprise a plurality of lamps, each lamp being associated with a respective key, said lamps being housed within a partitioned cage disposed over the lower surface of said screen.
