REPLACEABLE BLADE FOR MICROTOME AND MEANS FOR KEEPING SLICED SPECIMEN AGAINST CURLING

摘要

A means used for a replaceable blade or knife in a microtome to keep a sliced specimen against curling has a first plate laid to overlap on top of the replaceable blade and another plate joined with the first plate to extend ahead of a cutting edge of the blade in a direction of blade travel to keep the sliced specimen against curling as well as any operator against injury. Between the overlap plate over the replaceable blade and another plate to keep the specimen against curling, a slit to expose the cutting edge of the blade lying under the overlap plate is made lengthwise of the overlap plate in geometry crossing the blade travel. Thus, not only the sliced specimen of thin section is kept against curling which whirls around, but also any fingers of the operator are protected from accidental injury. Instant inspection of the sliced specimen of thin section can be easily performed with the aid of the present curling-prevention means for the replaceable blade simple in construction.
