PROBLEM TO BE SOLVED: To provide a screen printer capable of through-hole printing on a workpiece by moving two tables.SOLUTION: While a lower table 21 and an upper table 22 are moving, an auxiliary cylinder 65 of the upper table 22 raises a table upper part 40 of the upper table 22, and the lower table 21 passes under the upper table 22. A front roller 44 is pressed against a front vertical surface 13, and the table upper part 40 is vertically raised to be positioned at a printing height. A rear roller 48 of the upper table 22 is pressed against a rear vertical surface 15, and a piston 63 of the auxiliary cylinder 65 is lowered so that the upper table 22 becomes as high as the lower table 21 to allow a workpiece 210 to be carried in and out. A suction apparatus 220 vertically moves, and sucks and attaches to a lower surface of the table, thereby realizing through-hole printing.SELECTED DRAWING: Figure 1 |
