Abstract
Abstract An automatic driving and control circuit for a microscope stage mounted movably in two directions, which can automatically drive the microscope stage in the given directions. Provision is made of a detector for detecting the amount of movement of the stage and a preset means for presetting a predetermined amount of movement of the stage. When the amount of movement supplied from the detector is coincident with the amount of movement preset by the preset means, a coincidence signal is delivered to stop the stage, whereby the amount of light absorbed by substance disposed on the stage, for example, a cellular specimen is automatically measured in an accurate manner.
