摘要: A two-shaft drive mechanism includes a processing unit, a first linear motor provided with a first movable portion and a first fixed portion, which elevates the processing unit along a first linear guide, and a second linear motor provided with a second movable portion and a second fixed portion, which moves the processing unit in a horizontal direction vertical to the direction for elevating the processing unit, a support body that fixes the first fixed portion, a second linear guide that is provided between the support body and the second fixed portion, and allows the second fixed portion to freely move, and a control unit that controls a position of the first movable portion in the horizontal direction based on an output of the linear sensor that detects a position of the first movable portion in a horizontal direction with respect to the support body.
