Abstract
A screen printer effects a printing by moving a squeegee in contact with a screen to force a printing paste through a printing pattern formed on the screen. The squeegee is held by a squeegee head. The squeegee head includes a support member for supporting the squeegee in such a manner as to move the squeegee upward and downward, and at least one moving member which swingably supports the support member and is movable together with the support member. When the squeegee is to be exchanged, only the support member is angularly movable relative to the moving member so as to provide a sufficient space above the screen to facilitate the exchange of the squeegee.
Claims13
