Abstract: An environmentally protected keyboard display and input device is provided which may be utilized in conjunction with a variety of digital control systems such as automated bank tellers or building security systems. The keyboard display and input device includes a unitary, transparent flexible keyboard having thickened portions forming keys. The keyboard forms an environmental seal including a peripheral gasket to protect an underlying, transparent, pressure sensitive switching assembly, which, in turn, overlies a corresponding visual display of alphanumeric characters which indicate the significance of the individual pressure sensitive switches and corresponding keys overlying each character. Pins are formed on the underside of the flexible keyboard, below each key, to focus and concentrate pressure exerted on each key to the corresponding pressure sensitive switch below. An optical grid is provided to restrict the viewing of the alphanumeric characters to the user of the device, to prevent compromising the data input.

Abstract: An environmentally protected keyboard display and input device which may be utilized in conjunction with a variety of digital control systems such as automated bank tellers or building security systems. The keyboard display and input device includes a unitary, transparent flexible keyboard (16) having thickened portions forming keys (36). The keyboard forms an environmental seal including a peripheral gasket to protect an underlying, transparent, pressure sensitive switching assembly (18), which, in turn, overlies a corresponding visual display (24) of alphanumeric characters which indicate the significance of the individual pressure sensitive switches and corresponding keys overlying each character. Pins (66, 68) are formed on the underside of the flexible keyboard (16), below each key (36), to focus and concentrate pressure exerted on each key to the corresponding presure sensitive switch below. An optical grid (22) is provided to restrict the viewing of the alphanumeric characters to the user of the device, to prevent compromising the data input.
