Abstract

A microtome blade changing apparatus for a knife holder (1) of a microtome comprises a blade dispenser (4) storing unused blades and a blade container (5) for receiving used blades. The blade dispenser (4) and blade container (5) are respectively arranged adjacent to the knife holder (1). To reduce the risk of injury to an operator in the context of a blade changing operation, enable operation of the microtome blade changing apparatus reliably and in simple fashion, and allow economical manufacture of the microtome blade changing apparatus, the microtome blade changing apparatus is characterized in that an entraining element (13) manually actuable by an operator is provided, and is configured in such a way that an unused blade is transferable with the entraining element (13) from the blade dispenser (4) to the knife holder (1), and a used blade is thereby conveyable into the blade container (5).
