Abstract

A screen printing apparatus includes print executing parts, first and second substrate loading parts and a substrate unloading part, and first and second substrate support tables for supporting a substrate. The first substrate support table moves between a first receiving position where the substrate loaded from the first substrate loading part is received, and a sending position where the substrate is unloaded from the substrate unloading part. The second substrate support table moves between a second receiving position where the substrate loaded from the second substrate loading part is received, and the sending position. The print executing parts are respectively placed at positions on the substrate support tables where printing on the substrate is enabled.
