Abstract

A microtome (1) having a motorized feed drive system (2) for generating a relative movement between an object (7) that is to be cut and a cutting knife (4). A control circuit (8) and a pressure-sensitive sensor (9) are provided for detecting a position between the cutting knife (4) and the object (7). The motorized feed drive system (2) is switched via the control circuit (8) when the sensor (9) responds. The sensor (9) is equipped with a sensor surface (14) that is at least exactly as large as the surface (16) of the object (7). The sensor surface (14) is arranged parallel to the cutting plane (17).
