Abstract
In a mask printing machine, a target through hole, which is at least one of multiple through holes formed on the mask, is imaged by an imaging device when the board is below the mask and is at a separated position that is separated from the mask, and when the board is at a contact position in which an upper surface of the board contacts a lower surface of the mask, respectively. Based on a captured image, when the board is at the separated position, and a captured image when the board is at the contact position, it is possible to acquire the movement state of at least one target through hole when the board is lifted from the separated position to the contact position.
