Input keyboard apparatus for information processing device and other keyboard devices

摘要

An input keyboard unit includes a left and right keyboard. A separate universal pivot support unit is secured one to each keyboard and to a base support plate. Each universal pivot unit includes a telescopic shaft with a releasable connector for holding of the shaft in desired extended position. One end of the shaft or post unit is secured to the keyboard through a mounting plate. A ball and socket unit is secured to the opposite end and through a tongue and groove connection to a base plate for lateral positioning of the pivot units and the attached keyboard relative to each other. The ball and socket unit allows universal pivoting of the keyboard about the mounting to the base plate and thereby permits the optimal positioning of the keyboard with respect to the hands of the operator. In one embodiment, the two separate keyboard boards are generally rectangular members. A universal pivot units interconnects the top inner corners of the two keyboards whereby a generally inverted V-shaped spacing is provided between the two keyboards with each keyboard having a front-to-back inclination and a lateral side inclination with the universal pivot units of the keyboards permitting the precise optimal setting for any given individual or group of individuals. The keyboard connecting pivot unit is releasable to allow lateral spacing of the keyboards where desired or necessary for any given individual.
