An automatically controllable microscope stage positioning system capable of repeatable, precise adjustment for use in an automatic scanning microscope is disclosed. The system includes a slide tray in which an object slide is mounted and which is adjustable in the x-y plane and along the z axis to achieve automatic scanning and focusing functions in the automated microscope system. The positioning is achieved by using x, y and z axially adjustable lead screws which operate through non-rotating contact nuts to apply a force to move the stage in one direction along each of said x, y and z axes. Return springs which apply a force vector opposite that of the lead screws maintains the stage against the reversible lead screws at all times. Guide means are also provided for maintaining the alignment of the slide tray in both the x-y plane and along the z axis. The drive is controlled by means of signals generated by the automatic microscope signal processing system.
