Miniature keyboard with sliding keys

Abstract

Abstract A miniature keyboard assembly for generating code signals representative of selected characters and functions. The assembly including at least one but preferably, two glide keys, each coupled to a depressible keybutton for controlling the movement of its respective keybutton. In one embodiment, each keybutton base carries an electrically conductive layer and is slidable on a membrane panel having thereon a plurality of signal code generating switches. The keybutton being movable along orthogonal axes in response to movement of the glide key. Each keybutton extends upwardly through a longitudinal slot opening in a lateral slide support member and then through a fitted opening in an indicator panel. The indicator panel also include an indicia marker which underlies a transparent keyboard panel and is visible therethrough. Finger movement of the glide key causes the marker to indicate the character or function on the keyboard representative of the signal code to be generated by the switch over which the keybutton is positioned. Depression of the keybutton results in the activation of the switch and the generation of the selected signal code.
