Abstract
A screen-printing machine includes a mask holding device; a board holding device configured to grip a board; a positioning device to relatively position the board and the mask; and a control device. The board holding device includes a lifting and lowering table positioned in an up-down direction by a lifting and lowering mechanism, and a backup block including a mounting surface on which the board is placed, an installation surface disposed parallel to the mounting surface on an opposite side thereof, multiple suction holes to penetrate in a thickness direction between the mounting surface and the installation surface, and a chamber recessed section formed on an installation surface side so as to surround positions of the multiple suction holes, and in which an air chamber made by the chamber recessed section is configured when the backup block overlaps an upper face of the lifting and lowering table.
