A knife holder 100 with a blade changing apparatus comprising a first blade receptacle 111 defining a cutting position, securing means 130 for securing a blade 201 received in the first blade receptacle, a second blade receptacle 112 defining an output position and ejection means 140 for ejecting the blade from the first blade receptacle. The first and the second blade receptacles are so arranged in the knife holder that a blade ejected from the first blade receptacle can travel by gravity into the second blade receptacle. The first and second blade receptacles may be arranged to be spaced vertically apart. Preferably the knife holder is a microtome including a first external mounting location for a blade supply container, and a second external mounting location for a blade disposal container, where both are arranged to be vertically spaced from one another and horizontally spaced from the first and second blade receptacles respectively. Driver actuation element 304 may convey the blade into the first blade receptacle from the blade supply container and convey a used blade from the second blade receptacle into the blade disposal container, preferably simultaneously. |
