Abstract
A squeegee head having a volume-variable container and a printing space is used. The volume-variable container is variable in capacity with pressures applied thereto. The volume-variable container includes a projecting portion having a plurality of projections, a push-plate with a plurality of through-holes formed therein, and a side wall. A paste is stored in the volume-variable container. The projecting portion is pressurized to move and the paste is pushed out into the printing space from the through-holes, and then, the projections are fitted into the through-holes. In this way, the paste being stable in viscosity is completely pushed out into the printing space without wasting at all.
