Abstract:
1. A screen printing apparatus mounted to a component mounting line, the apparatus comprising: two printing portions that perform a screen printing, and that are arranged symmetrically to each other with respect to a perpendicular symmetrical plane extending in a transportation direction of a substrate in the component mounting line; and substrate moving stages that are provided so as to respectively correspond to the two printing portions, and which receive the substrate from an upstream side so as to position the substrate with respect to the respective printing portions and move the substrate subjected to the screen printing by the respective printing portions so as to discharge the substrate to a downstream side of the component mounting line; when ending the screen printing performed to the substrate by the respective printing portions, the substrate is moved from the respective printing portions so as to discharge the substrate to the downstream side of the component mounting line by the substrate moving stage, wherein the substrate subjected to the screen printing by one or the other of the two printing portions is discharged to the downstream side of the component mounting line at one of two different discharging positions depending upon which of the two printing portions prints the substrate, and wherein the two different discharging positions are separate from the perpendicular symmetrical plane and all parts of the printing portions are positioned further from the perpendicular symmetrical plane than the two different discharging positions.
