Abstract

The microtome of the present invention includes a base, a knife for cutting a sample, a knife holder fixed on the base and holding the knife, a carrier bar carrying the sample at the leading end thereof and vertically traveling with the trailing end as a fulcrum. A bar traveling mechanism supports and moves the carrier vertically. A transmission lever transmits force to feed the leading end of the carrier bar toward the knife. A support plate is mounted on the base and rotatably supports the transmission lever. A tension spring pulls the carrier bar toward the transmission lever. A lever moving mechanism is in contact with the transmission lever.

Dependent claims

A microtome, comprising:

a base;
a knife;
a knife holder, mounted on said base, that holds said knife;
a carrier bar having a leading end which can support a sample in proximity to said knife, and a trailing end having a wedge shaped edge which acts as a fulcrum about which said carrier bar can pivot;
a bar traveling mechanism that supports said carrier bar and for pivoting said carrier bar about said wedge shaped edge;
a lever moving mechanism;
a transmission lever having a first end in contact with said lever moving mechanism and a second end having a recess which engages said wedge shaped edge of said trailing end;
a support plate, mounted on said base, which rotatably supports said transmission lever;
and
at least one tension spring which pulls said carrier bar toward said transmission lever;
wherein said lever moving mechanism moves said transmission lever to move said leading edge of said carrier bar toward and away from said knife.
