# Sample conveyance system and sample conveyance method

## 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 unit 208 applies a first voltage to a first coil 207 a located on a front side in a traveling direction of a holder 202 , which is selected to attract or repel the holder 202 , to excite the first coil 207 a and applies a second voltage having a polarity opposite to a polarity of the first voltage to at least one or more of second coils 207 b among coils 207 adjacent to the first coil 207 a except for the coils 207 in the front side in the traveling direction to excite the second coil 207 b , and a control unit 210 A estimates a position of the holder 202 based on a value of a current flowing through a winding 206 of the first coil 207 a.
