Method and Microtome for Producing Thin Sections with a Section Profile Recording Mode
First Claim
1. A method of producing thin sections by means of a microtome, wherein a hand wheel (32) is manually driven for producing a first thin section, andwherein the rotational movement of the hand wheel (32) during production of the first thin section is detected by means of an encoder (38), and a profile of the rotational movement is determined,wherein the determined profile is stored in a storage element (42),wherein a plurality of profiles are determined by means of the encoder (38), said profiles being stored in the storage element (42),wherein at least one characteristic feature is stored, unambiguously assigned to each profile,wherein one of the prior stored profiles is selected for producing at least a second thin section,and wherein a motor (24) for generating a cutting movement between a cutting unit (16) and a sample holder (12) is driven in accordance with the respective stored profile selected, for producing the second thin section.

Abstract
The present invention relates to a method of producing thin sections by means of a microtome, wherein a hand wheel (32) is manually driven for producing a first thin section, and wherein the rotational movement of the hand wheel (32) is detected by means of an encoder (38), and a profile of the rotational movement is determined. The determined profile is stored and selected for production of at least a second thin section. A motor (24) is driven for generating a cutting movement between a cutting unit (16) and a sample holder (12) in accordance with the respective stored profile selected for producing the second thin section. The invention further relates to a microtome (10) by means of which the above method is carried out.

14. A microtome for producing thin sections, comprising:
-
a sample holder (12) for receiving a sample to be microtomed, a cutting unit (16) for cutting the sample, a motor (24) for generating a relative movement between the sample holder (12) and the cutting unit (16) for cutting the sample, a manually operable hand wheel (32), an encoder (38) for detecting a rotational movement of the hand wheel (32), and a control unit (40) for driving the motor (24), characterized in that, in a recording mode, the control unit (40), using the encoder (38), determines a plurality of profiles of rotational movements (32) performed for cutting thin sections, the control unit (40) stores the profiles in a storage element (42), the control unit (40) stores for each profile at least one characteristic feature unambiguously assigned thereto, and wherein the control unit (40), when producing at least one further thin section, drives the motor (24) in accordance with a prior stored, selected profile.
