Abstract
The present invention relates to a device for controlling a brake of a microtome. The microtome (1) has an actuating element (2), a movement mechanism (8) and a brake. With the aid of the movement mechanism (8), an object to be cut can be moved relative to a knife blade. The actuating element (2) can be manually actuated by an operator and, as a result thereof, the relative motion between the object and the knife blade can be performed with the movement mechanism (8). The relative motion can be locked with the aid of the brake. So that the relative motion between the object and the knife blade can be used in a mechanically designed movement mechanism (8) and/or the relative motion can be locked without an additional hand movement of the operator, the inventive device is characterized by at least one sensor unit (5, 13). The sensor unit (5, 13) is provided on the actuating element (2) or adjacent to the actuating element (2). With the aid of the sensor unit (5, 13) a contact by the operator can be determined. The device is further characterized by a control of the brake depending on a contact by the operator determined or not determined by the at least one sensor unit (5, 13).
