Abstract: A screen printing apparatus moves a mask, inserted through an insertion opening, to a printing position at which paste is printed onto a substrate via a mask moving mechanism, and includes: a first detecting unit that detects one of a front frame component and a back frame component of the mask at a first detection position on a path along which the mask inserted through the insertion opening is moved to the printing position; a second detecting unit that detects one of the front frame component and the back frame component at a second detection position closer to the printing position than the first detecting position is; and a print suspension controller that suspends printing when the second detecting unit detects one of the front frame component and the back frame component while the first detecting unit is detecting one of the front frame component and the back frame component.

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.
