PURPOSE:To position a lower die without enlarging the lower die by projecting the lower die for a printed board press vertically on a lower die fixing surface and fixing the lower die when the projected center agrees with the fixing center of the lower die. CONSTITUTION:The lower die 18 of the printed board press 10 is moved along the lower die fixing surface of a lower die fixing part and maintaining such a state that a projection center O2 obtained by projecting the lower die 18 vertically on the lower die fixing surface is superimposed on a prescribed straight line L1 passing the fixing center O1 in the lower die fixing surface. When the lower die 18 is moved to a position where its projecting center 02 agrees with the fixing center O1 of the lower die fixing surface, the lower die 18 is stopped and the lower die 18 is fixed there. |
