ABSTRACT:
A mechanism is disclosed for use in supporting a keyboard in a desired adjustable position relative to a CRT unit at a work station. The mechanism is adapted for attachment to the downwardly facing surface of a suitable horizontal support arranged at various levels or distances from a floor; and is characterized as being capable of mounting a keyboard for horizontally directed movements between storage or retracted and use or extended positions and for vertically directed movements into maximum upper and lower use positions in opposite directions from an intermediate or reference position normally assumed by the keyboard when in its storage position, wherein means are provided to automatically move the keyboard from its upper position into its intermediate position incident to movement of the keyboard horizontally towards its storage position.
