Abstract
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.
