ABSTRACT:
A microtome has a frame structure in which an object holding member for holding an object to be thinly cut is movable with an oscillating movement by a drive device. The object holding member has a cutting thickness feed member and an object return member, the latter including a switch element disposed on the object holding member for oscillating movement therewith. The frame structure carries first and second abutments arranged at the respective end portions of the path of movement of the switch element which oscillates with the object holding member. The switch element is thus displaceable by co-operation with the first and second abutments between first and second positions respectively; when the switch element is in its first position the object holding member is in a position in which it is set back from the cutting plane while when the switch element is in its second position the object holding member is in a position of being advanced into the cutting plane for an object-cutting operation.
