Abstract
A screen printing machine comprises a conveyor for conveying a substrate to a positioning station, an XY.theta. table on which the substrate is to be put, and a printing device for printing a pattern onto the substrate in a printing station. The XY.theta. table is movable in an XY.theta. plane in the positioning station and also movable along a Z-direction perpendicular to the XY.theta. plane. The machine further comprises a device for moving the printing device between the printing station and a waiting station, an image processing device and a driving device for the XY.theta. table. The image processing device recognizes a position of the substrate and calculates the respective amount of movement of the XY.theta. table in the XY.theta. plane necessary for making the predetermined relative positional relation between the printing device and the substrate. The driving device moves the XY.theta. table, based on the amounts of movement calculated by the image processing device.
