Abstract: A screen printing apparatus includes an inspection region setter and an operation stop controller. The inspection region setter sets an inspection region in an inspection plane that intersects with a moving path of a mask until the mask positioned at a printing-job performing position moves to a mask shelter position by the moving mechanism. In addition, the inspection region setter excludes a passing region of the mask from the inspection region while the mask to be positioned at the mask shelter position passes over the inspection plane from the printing-job performing position.
