To suppress liquid wavering corresponding to the switching of an energized coil in a carrier apparatus.SOLUTION: A carrier apparatus for carrying a to-be-carried article with a magnetic material comprises: a plurality of coils for generating a thrust for carrying the to-be-carried article; a coil drive unit for applying a pulsed voltage to each of the plurality of coils; and an arithmetic unit. The arithmetic unit determines a width of the pulsed voltage so that a speed or an acceleration speed of the to-be carried article is stabilized based on a position, and a time of passing the position, of the to-be-carried article during a prescribed period before the switching of the energizing, or current that flows through the energized coil when switching the energized coil, to be output to the coil drive unit.SELECTED DRAWING: Figure 3 【課題】搬送装置において通電するコイルの切替に伴う液揺れを抑制する。【解決手段】磁性体を有する被搬送物を搬送する搬送装置であって、被搬送物を搬送するための推力を発生させる複数のコイルと、複数のコイルのそれぞれにパルス状の電圧を印加するコイル駆動部と、演算部と、を備え、演算部は、通電するコイルを切替える際には、当該通電切替以前の所定期間における被搬送物の位置及びその位置を経過した時刻又は通電しているコイルに流れた電流に基いて、被搬送物の速度又は加速度が安定するようにパルス状の電圧の幅を決定し、コイル駆動部に出力する。【選択図】図３
