To provide technology to detect, with high sensitivity, a position of each actuator (magnetic pole) without using a container carrier detection device.SOLUTION: The present disclosure proposes a conveying device that conveys a conveyance container including a magnet or a magnetic body to a target position along a conveyance path, the conveying device including: a conveyance surface configured by arranging a plurality of magnetic poles including a core and a coil, and having a conveyance path; a drive unit for supplying a current to the coil; and a position detection unit for performing a process of estimating a position of the conveyance container. The position detection unit is configured to perform: a process of determining a plurality of magnetic poles around a currently scheduled conveyance position as a first magnetic pole that is a candidate for the position of the conveyance container on the basis of a conveyance history information on the conveyance path of the conveyance container; a process of exciting the first magnetic pole, and applying a voltage to at least one second magnetic pole that is a peripheral magnetic pole within a predetermined range from the first magnetic pole and is different from the first magnetic pole in a direction in which the polarity becomes opposite to an exciting current of the first magnetic pole; and a process of determining presence or absence of the conveyance container on the basis of a current value of a plurality of the first magnetic poles.SELECTED DRAWING: Figure 11 【課題】容器キャリア検出デバイスを用いずに各アクチュエータ（磁極）の位置を感度よく検出する技術を提供する。【解決手段】本開示は、磁石または磁性体を含む搬送容器を搬送経路に沿って目標位置に搬送する搬送装置であって、コアとコイルを含む磁極を複数個配置して構成され、搬送経路を有する搬送面と、コイルに電流を供給する駆動部と、搬送容器の位置を推定する処理を実行する位置検出部と、を備え、当該位置検出部は、搬送容器の搬送経路上での搬送履歴情報に基づいて、現時点で予定される搬送位置周辺の複数の磁極を、搬送容器の位置の候補となる第１磁極とする処理と、第１磁極を励磁すると共に、第１磁極から所定範囲にある周辺の磁極であって第１磁極とは異なる少なくとも１つの第２磁極に対して第１磁極の励磁電流とは逆極性となる向きに電圧を印加する処理と、複数の第１磁極の電流値に基づいて、搬送容器の有無を判断する処理と、を実行する搬送装置を提案する。【選択図】図１１
