ABSTRACT:
A microtome with a drive device is described, which has a shaft and a handwheel, arranged thereupon, with a grip. For locking the drive device, an electromagnet is firmly arranged on the housing frame of the microtome. The latter is in effective connection with an indexing ring, axially displaceable on the shaft. A control device, which is electrically connected to the electromagnet and to a sensor, controls the electromagnet in response to a signal of the sensor. The sensor triggers the signal by the position of an indexing ring arranged axially displaceably on the shaft. The said indexing ring is movable in frictional connection with a pin arranged in the grip and axially displaceable by means of a lever. The lever is actuated by seizing of the grip and the locking of the drive device is cancelled.
