Abstract: A thin-section preparation method and device includes, in a one-blade set state where an entire first cutting blade is held by a holder, performing a first rough cutting step of rough cutting an embedded block using a first end region of the first cutting blade, and a first main cutting step of main cutting the embedded block using a second end region of the first cutting blade; and further includes, in a two-blade set state where the second end region of the first cutting blade and a first end region of a second cutting blade are held by the holder, performing a second rough cutting step of rough cutting the embedded block using the second end region of the first cutting blade, and a second main cutting step of main cutting the embedded block using the first end region of the second cutting blade.

Abstract: A block storage device includes: a magazine which accommodates embedding blocks to be inserted into or removed from the magazine in a state where the embedding blocks held in a cassette to which ID data is attached are arranged vertically in one row; a magazine holding portion which detachably holds each of the magazines; and a reading portion which reads the ID data. The magazine holding portion includes a rotary body which is rotatable around a rotation axis O, a holding mechanism which is multiply provided on a circumferential wall portion in the rotary body and detachably holds the magazines individually, and a rotation drive portion which positions one of the magazines at a block extraction position facing the reading portion by rotating the rotary body, and the magazine positioned at the block extraction position and the reading portion are movable relative to each other along the vertical direction.

Abstract: A thin-section preparation method includes: a first rough cutting step performing rough cutting of the embedded block in one end region of a first cutting blade, in a one-blade set state where entire of the first cutting blade is held by a holder; a first main cutting step performing main cutting of the embedded block in another end region of the first cutting blade in the one-blade set state; a second rough cutting step of performing rough cutting of the embedded block in the other end region of the first cutting blade, in a two-blade set state where the other end region of the first cutting blade and one end region of a second cutting blade are held by the holder; and a second main cutting step of performing main cutting of the embedded block in the one end region of the second cutting blade in the two-blade set state.
