Abstract
A micromanipulator apparatus includes an operation handle joined to a slide plate for moving the slide plate forward and backward and leftward and rightward. A first lever joined to the slide plate is rotated in forward and backward direction around a supporting point pin by means of a first guide pin engaged in a first slot in the slide plate, and a second lever is rotated in leftward and rightward direction around a second supporting pin by means of a second guide pin engaged in a second slot in the slide plate. Separate hydraulic devices are operated in response to activation by working rods associated with the respective levers. Movement of the slide plate and operation of the hydraulic devices provides precise movement to a workpiece supported by the apparatus.
