Sample stage for magnetism measuring apparatus

PURPOSE: To achieve a smaller size of the apparatus and higher efficiency of origin indexing work by arranging a plurality of sample containers filled with samples labeled magnetically on the circumference of a sample base formed in disc to form a cut part at the part of the sample base between sample containers adjacent to each other. CONSTITUTION: A sample stage 13 is made up of a disc 18 and a sample container 19 and sample container placing holes 20 are formed at an equal interval on the circumference near the periphery thereof. Moreover, a part of the disc 18 is cut between the placing holes 20 to form a sector-shaped cut part 22 lest magnetism should leak to a sample labeled magnetically adjacent to the sample labeled magnetically to be applied. The size of the cut part 22 is so set the yokes 16 and 16' do not obstacle the vertical movement of the sample base 13. This enables the prevention of the magnetic leakage to the adjacent magnetically labeled sample requiring no so large interval with the adjacent sample container. It is also possible to let the sample base 13 move vertically without returning a finely adjusting base 25 to the horizontal origin position. COPYRIGHT: (C)1993,JPO&Japio
