Abstract
A substrate transfer mechanism includes a moving body, a support body supported by the moving body, first and second rotary shafts at the support body, first and second arms respectively extending from first and second rotary shafts and having first and second substrate support regions. The first arm and the second arm are disposed at different height positions. The mechanism includes a third rotary shaft rotating the support body with respect to the moving body, and a switching mechanism switching a first rotation operation of rotating the support body such that a distance in a right-left direction between the first and second substrate support region is maintained and a second rotation operation of rotating the support body together with rotation of at least one of the first and second rotary shaft such that the distance is changed between a first distance and a second distance shorter than the first distance.
