ABSTRACT:
The present invention relates to a screen printing apparatus comprising a support mechanism for supporting the material to undergo printing; a printing plate in which an ink penetrating portion is formed possessing the shape of the print; a printing plate housing for housing the printing plate at a position in contact with the material to undergo printing; a slider which is capable of bi-directional horizontal movement with respect to the printing plate; a slider driving mechanism for driving the slider bi-directionally; a first squeegee and a second squeegee for spreading over the printing plate ink supplied to the printing plate; and a squeegee switch mechanism installed in the slider for supporting the first squeegee and the second squeegee, and for selecting one of these first squeegee and second squeegee, and placing the selected squeegee in contact with the printing plate. In this manner, a sheet support mechanism for supporting a sheet; a plate unit formed from a printing plate and plate housing; and an ink imprinting mechanism are provided. The aforementioned ink imprinting mechanism comprises the aforementioned first squeegee and second squeegee; slider; a belt for moving the slider in both directions, and a first cylinder and second cylinder for raising and lowering each squeegee. The printing plate is formed from a material incorporating a ferromagnetic substance, and electromagnets and/or permanent magnets are arranged in the aforementioned sheet support mechanism.
