Abstract

The invention comprises a finger actuated one handed keyboard having a palm rest portion for the palm of the operator'"'"'s hand to rest upon, and at least three finger actuated sleeve receptacle assemblies. Each assembly has an outer lateral extending sleeve pivotally connected to a longitudinally extending inner half sleeve aligned for receiving the outer and inner portions, respectively of a finger; and a plurality of finger actuated key members with at least two key members aligned in front and behind the lateral outer sleeve and confronting the pivotal path of longitudinal movement of the lateral outer sleeve in either direction and adapted, upon longitudinal movement in either direction by the outer finger portion about the middle joint in either direction, to actuate either confronting key. Each sleeve receptacle assembly has a third one of the plurality of key members mounted below the pivotal longitudinal extending half sleeve to be actuated by the inner portion of the finger pivoting downward about its inner pivot against the half sleeve to pivot the half sleeve laterally downward against the third key member to actuate the third key member, separate from the actuation of the two key members by the outer sleeve, and with the outer two key members being actuatable by the longitudinal movement of the outer sleeve when the inner half sleeve is in either is upper or pivotal downward position, separate from the actuation of the third one key member. The keyboard also has a thumb receptacle movable by the thumb of of the operators hand to actuate a plurality of key members, while the fingers of the hand operate the finger sleeve assemblies to actuate the finger key members.
