Abstract
A screen printing apparatus 199, 169 has a roll paper vibrating device which vibrates roll paper in contact with the lower surface of a screen mask in a direction perpendicular to a moving direction of the roll paper while the roll paper is being moved in contact with the lower surface of the screen mask. Thereby, the roll paper in contact with the lower surface of the screen mask is moved in a waveform-shape pattern. Therefore, the cumulative contact area of the roll paper on the lower surface of the mask is increased, and it is possible to efficiently remove residue, such as paste attached onto the lower surface of the screen mask of the printing apparatus and paste attached inside pattern openings of the screen mask, to maintain a good printing performance.
