Abstract
A microtome actuable both manually and by a motor, with a single coupling element, whereby rotation of the hand wheel when the motor drive is engaged and thus the risk of injury by the manual grip are excluded. The coupling element is located in the hand wheel and is capable of locking in two positions by means of pulling and rotating, the respective positions establishing the manual or motor drive mode. The drive mode is made readily apparent from the outside by means of symbols. In the hand wheel, an equalizing weight for the object carriage is provided.
