Abstract
A microtome for stable production of continuously cut thin sections of a specimen for electronmicroscopic examination by an electromagnetic drive mechanism. Employing a lever hinged so as to swing in a dynamically balanced state, and a specimen holder attached to one end of the lever opposite to a knife, the electromagnetic mechanism drives the other end of the lever so that on every swinging of the lever the specimen is cut by the knife with accurate speed control for continuously cutting. Also, the electromagnetic drive realizes an automated specimen cutting cycle.
