Abstract
A precision slide positioning system is disclosed which is particularly adapted for rigid and repeated positive location of a microscope object specimen slide relative to the movable stage of a scanning automated microscope such that a predetermined field of view based on perpendicular axis in the plane of the slide carrier tray can be automatically recalled after removal and subsequent replacement of the slide on the slide carrier plate. A pair of oppositely disposed, resiliently held slide retainers are provided which, operating on the slide, urge the slide against fixed alignment registration guides on the slide tray to retain the slide in a predetermined fixed parallel relation thereto. The slide is, in turn, held in adjustable fixed alignment with the traverse plate of the microscope stage. A release mechanism mechanically linked to both of the retainers is provided to withdraw the resiliently held retainers for ease of slide removal and insertion.
