Abstract

The invention provides a conveyance device having a smaller loss of a winding than that of a related art while increasing thrust for conveying a body to be conveyed, and a specimen analysis system and a specimen pretreatment device including the same. A conveyance device 1 includes: a permanent magnet 10 provided on the side of a specimen rack 111; teeth 22 formed of a second magnetic body; and a winding 21 wound around the side of an outer periphery of the teeth 22, wherein a cross-sectional area of a cross section of a part of the teeth facing the permanent magnet 10 is larger than that of other parts thereof. Alternatively, the conveyance device 1 includes: the permanent magnet 10 provided on the side of the specimen rack 111; the teeth 22 formed of the second magnetic body; and the winding 21 wound around the side of the outer periphery of the teeth 22, wherein a gap Lc between the permanent magnet 10 and the winding 21 and a gap Lt between permanent magnet 10 and the teeth 22 satisfy a relationship of Lc>Lt.

First claim

1 . A conveyance device, comprising:
a first magnetic body provided on a side of a body to be conveyed; teeth formed of a second magnetic body; and a winding wound around a side of an outer periphery of the teeth, wherein a cross-sectional area of a cross section of a part of the teeth facing the first magnetic body is larger than that of other parts thereof.

2 . The conveyance device according to claim 1 , wherein
among the teeth, the cross-sectional area of the part of the teeth facing the first magnetic body is larger than a cross-sectional area of a part thereof around which the winding is wound.

3 . The conveyance device according to claim 2 , wherein
a gap Lc between the first magnetic body and the winding and a gap Lt between the first magnetic body and the teeth satisfy a relationship of Lc>Lt.

4 . A conveyance device, comprising:
a first magnetic body provided on a side of a body to be conveyed; teeth formed of a second magnetic body; and a winding wound around an outer periphery of the teeth, wherein a gap Lc between the first magnetic body and the winding and a gap Lt between the first magnetic body and the teeth satisfy a relationship of Lc>Lt.

5 . The conveyance device according to claim 1 , wherein
the cross-sectional area of the cross section of the part of the teeth facing the first magnetic body is larger than that of other parts thereof.

6 . The conveyance device according to claim 1 , wherein
among the teeth, a shape of a surface of the teeth facing the body to be conveyed is circular or elliptical.

7 . The conveyance device according to claim 1 , wherein
among the teeth, a shape of a surface of the teeth facing the body to be conveyed is polygonal.

8 . The conveyance device according to claim 7 , wherein
among the teeth, the shape of the surface of the teeth facing the body to be conveyed is rectangular.

9 . The conveyance device according to claim 8 , wherein
among the teeth, a corner part of the surface of the teeth facing the body to be conveyed faces a conveyance direction of the body to be conveyed and a direction perpendicular to the conveyance direction thereof.

10 . The conveyance device according to claim 8 , wherein
among the teeth, a corner part of the surface of the teeth facing the body to be conveyed faces a direction inclined by 45 degrees in a conveyance direction of the body to be conveyed.

11 . The conveyance device according to claim 1 , wherein
among the teeth, a surface of the teeth facing the body to be conveyed becomes thinner continuously or stepwise as approaching the side of the body to be conveyed.

12 . The conveyance device according to claim 1 , wherein
among surfaces of the teeth facing the body to be conveyed, a length is different between a conveyance direction of the body to be conveyed and a direction perpendicular to the conveyance direction thereof.

13 . The conveyance device according to claim 1 , wherein
among surfaces of the teeth facing the body to be conveyed, a length in a direction inclined by 45 degrees in a conveyance direction of the body to be conveyed is different from a length in the conveyance direction thereof or in a direction perpendicular to the conveyance direction thereof.

14 . The conveyance device according to claim 1 , wherein
a width of the largest part of the teeth is 0.5 Pt or less with respect to a pitch Pt of the teeth.

15 . A specimen analysis system, comprising:
the conveyance device according to claim 1 .

16 . A specimen pretreatment device, comprising:
the conveyance device according to claim 1 .
