Conveying Device, and Analyte Analysis System

A conveyance device comprising:

• a conveyance plate that can convey a conveyed body along a conveyance surface;
• a magnetic circuit unit arranged on an opposite side of the conveyance surface of the conveyance plate and having a winding wound around teeth;
• a position detection unit configured to detect a position of the conveyed body;
• a current detection unit configured to detect a current in the winding;
• a gap estimation unit configured to estimate a gap that is a distance in a perpendicular direction between the conveyed body and the conveyance surface;
• a data storage unit configured to store data indicating a relationship among a position on a conveyance surface of the conveyance plate, a current flowing through the winding, a force applied to the conveyed body, and a size of the gap;
• and
• an abnormality determination unit configured to determine an abnormality regarding conveyance of the conveyed body including deterioration or abnormality of the conveyance surface based on gap estimated by the gap estimation unit, the position detected by the position detection unit, the current detected by the current detection unit, and the data.

A specimen analysis system comprising:

• an analysis unit configured to be injected with a specimen from a conveyed body and to analyze the specimen;
• and
• a conveyance device configured to convey the conveyed body toward the analysis unit, wherein
• the conveyance device includes
• a conveyance plate that can convey the conveyed body along a conveyance surface;
• a magnetic circuit unit arranged on an opposite side of the conveyance surface of the conveyance plate and having a winding wound around teeth;
• a position detection unit configured to detect a position of the conveyed body;
• a current detection unit configured to detect a current in the winding;
• a gap estimation unit configured to estimate a gap that is a distance in a perpendicular direction between the conveyed body and the conveyance surface;
• a data storage unit configured to store data indicating a relationship among a position on a conveyance surface of the conveyance plate, a current flowing through the winding, a force applied to the conveyed body, and a size of the gap;
• and
• an abnormality determination unit configured to determine an abnormality regarding conveyance of the conveyed body including deterioration or abnormality of the conveyance surface based on the gap estimated by the gap estimation unit, the position detected by the position detection unit, the current detected by the current detection unit, and the data.
