Transport device and analysis system

A transport device configured to transport a transport container having a magnet or a magnetic body, the transport device comprising:

• a plurality of coils configured to generate a thrust to transport the transport container;
• a coil drive unit configured to apply a voltage to each of the plurality of coils;
• and
• a calculation unit configured to estimate a position of the transport container based on current information when a voltage pulse is applied to the coils, wherein
• when a power supply of the device is activated, the calculation unit applies a voltage pulse in a positive direction and a voltage pulse in a negative direction to the target coils so as to detect the position of the transport container from the current information of current flowing through the coils,
• the current information used in the calculation unit is a current change amount which is a difference between a maximum current and a minimum current flowing through a coil when the voltage pulse in the positive direction and the voltage pulse in the negative direction are applied, and
• the calculation unit is configured to determine whether the transport container is present right above a coil when a voltage pulse in a first direction is applied to the coils and to determine whether the transport container is present at a position distant from the coil when a voltage pulse in a second direction is applied to the coils.
