Abstract

Abstract The present invention discloses a screen printing machine having a position adjusting means for carrying out adjustment of position of a material (10) to be printed having a plurality of alignment marks (10A, 10B) in a direction of X, Y and ϑ. The adjusting means com­prises a placing means (11) for placing and positioning the material (10) to be printed, a means (14, 15, 16) for displacing the placing means (11) in a direction of X and moving and carrying the placing means (11) from a recognition station to a printing station, and a means (27, 17. 19; 28, 18, 20) for displacing the placing means (11) in a direction of Y. The displacing means (27, 17, 19; 28, 18, 20) is composed of a mechanism in which both side portions of the placing means (11) are respectively independently displaced in the direction of Y to make adjustment of positions of the placing means (11) in the direction of Y and ϑ. The position adjusting means further comprises a recognition means (30) for recognizing alignment marks (10A, 10B) marked on the material (10) to be printed placed on the placing means (11) and a displacement means for displacing the placing means (11) in response to the recognition of the marks (10A, 10B) by the recognition means (30), the recognition means (30) being moved in a direction at right angles to the carrying direction of the material to be printed.
