Abstract
A screen printing apparatus includes: a positioning stage for positioning an object and a plate arranged above it; printing squeegees which are moved horizontally on the plate for printing through the plate onto the object; a driver for moving the positioning stage; a horizontal driver for moving the positioning stage in two substantially perpendicular directions; a positioning controller for calculating a central position of a pattern on the plate from a reference position and the size of an outer periphery of the object, moving the positioning stage so that the central position corresponds to a center of the object. A carry-in conveyor is provided for feeding the object onto the positioning stage along a predetermined transferring direction, the conveyor being arranged away from the positioning stage and having a carry-in conveyor surface on which the object is placed before the object is fed onto the positioning stage. The carry-in conveyor surface is positioned within the same plane as an object placing surface of the positioning stage. A carry-out conveyor is provided for transferring the object on the positioning stage along the transferring direction, the carry-out conveyor being arranged away from the positioning stage and having a carry-out conveyor surface on which the object is placed after the object is fed from the positioning stage. The carry-out conveyor surface is positioned within the same plane as the object placing surface of the positioning stage.
