Screen printing machine and electronic component mounting system

A screen printing machine for forming, on a board, a print of paste supplied to a mask plate having pattern holes in a state where the board contacts the mask plate,

• said screen printing machine comprising:
• a filling squeegee which is held to have a given clearance with respect to the mask plate, and which fills the pattern holes with the paste by moving the filling squeegee relative to the mask plate in a printing direction;
• an urging member which urges the filling squeegee toward the mask plate such that at least the given clearance is maintained;
• a scraping squeegee which is held to maintain a given interval from the filling squeegee in the printing direction, and which scraps off paste remaining on the mask plate after passage of the filling squeegee by moving the scraping squeegee together with the filling squeegee in the printing direction;
• and
• an attachment which attaches the filling squeegee to the scraping squeegee,
• wherein the attachment comprises a recess extending approximately vertically from a bottom surface of the attachment, and the urging member is placed in the recess.
