DEVICE AND METHOD FOR BRAKING A SHAFT OF A MICROTOME

摘要

The invention relates to a device for braking or locking the shaft (6) of a microtome (1). The microtome (1) comprises a shaft (6), an actuating element (2), a motion mechanism (37) and a housing (38). The motion mechanism (37) moves an object to be cut in relation to a knife blade. The actuating element (2) can be manually actuated by a user, thus causing the shaft (6) to rotate. The motion mechanism (37) for carrying out the relative motion between the object and the knife blade is driven by means of the shaft (6). The invention also relates to a method for operating a device for braking a shaft (6) of a microtome (1). To enable the device to be used with a mechanically designed motion mechanism (37), said device according to the invention is characterised by an actuator and a braking unit (25). The braking unit (25) is rotationally fixed to the shaft (6). By using the actuator, the braking unit (25) can be automatically moved into a braking position in which the shaft (6) can be rotationally fixed to the housing (11).
