PROBLEM TO BE SOLVED: To provide a more practical screen printing machine which is easy to open and close a cover thereof, and can easily obtain an effect resulting from that an operator supplies a cream-like solder by hand.SOLUTION: A solder supply window 260 is provided in an opening/closing cover 242 for covering a squeegee device 16 or the like, and a shielding device 280 is arranged inside. A shutter 282 of the shielding device 280 shields a print area corresponding to a substrate holding device 20 of a screen 100 from a solder supply area corresponding to a solder supply base 230. During supplying a solder, after an operator sets the shutter 282 in a shielding state, the operator opens a door 264, and mounts the solder on the solder supply base 230. After supplying the solder, the operator closes the door 264, and sets the shutter 282 in a non-shielding state, and squeegees 110, 112 take a supplied solder 400 into the print area by moving to the solder supply area. The operator can supply the solder while printing by shielding with the shutter 282 without touching the squeegees 110, 112 even if the door 264 is opened. It is possible that the shutter device 280 is omitted, and the squeegees 110, 112 supply the solder in a state of being positioned in a rear side position. |
