ABSTRACT:
A print mask apparatus has a pair of slide members provided on a base plate such as to oppose each other and supported such as to be independently movable in the direction orthogonal to the direction in which they oppose each other. The apparatus further has a pair of mask members respectively provided on the slide members and supported such as to be independently movable orthogonally with respect to the direction of movement of the slide members. Accordingly, it is possible for print sizes to be easily changed without any need to replace the mask members with others.
