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.

Abstract: A microtome particularly suitable for sectioning specimen to be observed on a transmission type electron microscope. Mounted on top of and located to one side of a machine base (2) are an X-Y axis stage and a tilting stage (4) which in turn supports thereon a cutter holder block (5) with a cutting knife (6). Located to the other side of the machine base (2) is a micro-feed mechanism (7) which supports thereon a specimen holder support arm (12) with specimen (14) and a Z-axis stage (11). The micro-feed mechanism (7) has first and second linear motor stages (8) and (9) to be displaced inversely in intersecting directions crossed each other with a predetermined intersection angle (28) across Y-axis. As the first and second linear motor stages (8) and (9) are displaced at the intersection angle (20) with each other, the specimen (14) is displaced over a small distance of nanometrically fine level in the direction of X-axis, thereby permitting to produce an ultra-thin specimen piece.
