A microtome for producing thin sections, in which the cutting operation is performed by way of a relative movement between a cutting knife and an object. A drive system ( ) having a drive motor ( ), a control circuit ( ), and a handwheel ( ) is provided to generate the relative movement. The handwheel ( ) is connected to an encoder ( ) that delivers corresponding signals to the control circuit ( ) upon rotation of the handwheel ( ). The drive motor ( ) is then activated accordingly by way of said control circuit ( ). In the absence of encoder signals, the drive system ( ) is locked.

Microtome

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