ABSTRACT:
A stage driving device for optical examining apparatus has a pair of moving beds capable of traveling in directions perpendicular to each other, straight guide members mounted on the moving beds, driving knobs coaxially arranged to move the moving beds, and a transmission mechanism converting a rotary motion of each of the driving knobs into a rectilinear motion of each of the moving beds. By the operation of the transmission mechanism, the movements of the moving beds can be made in two directions perpendicular to each other, independently or simultaneously. Additionally, the wear of parts of the straight guide members and the transmission mechanism is minimal and the use of inexpensive parts and the ease of assembly makes it possible to reduce the cost of the entire device.
