ABSTRACT:
The straight guide driving device comprises a guide rail fixedly attached to an immovable block such as the microscope body, a movable block such as a microscope tube block mounted so as to be displaced along the guide rail and a rack-pinion connection interposed between the immovable block and the movable block for driving the movable block. The rack-pinion connection has a pair of rack members which are fixedly attached to the movable block and arranged respectively in the vicinity of both the opposite sides of the guide rail. Accordingly, the movable block can perform straight movement with very high accuracy along the guide rail.
