Positioner

A positioner is equipped with a housing, a table, a drive unit, a tube, a first coil section, and a first cord. The tube has a first open section positioned at the center of rotation of the table, and a second open section connecting to the first open section and positioned on the opposite side from the first open section. The first coil section is positioned outside of the second open section of the tube. The first cord has a first draw-out section and a first take-up section. The first draw-out section is drawn out from the table through the inside of the tube from the second open section. The first take-up section is wound on the first coil section as the table rotates. The number of air tubes or electrical wires drawn out onto the table can be increased while keeping the positioner from becoming much larger.
