Abstract
There are provided a sample conveyance system and a sample conveyance method capable of conveying a sample in a more stable manner than in the related art corresponding to a conveyance method using an electromagnetic actuator. A driving unitapplies a first voltage to a first coillocated on a front side in a traveling direction of a holder, which is selected to attract or repel the holder, to excite the first coiland applies a second voltage having a polarity opposite to a polarity of the first voltage to at least one or more of second coilsamong coilsadjacent to the first coilexcept for the coilsin the front side in the traveling direction to excite the second coil, and a control unitA estimates a position of the holderbased on a value of a current flowing through a windingof the first coil
