摘要：
A printing plate is held at one point thereof by a holding portion provided at a surface plate. When pushed by a pushing portion, the printing plate is only rotationally displaced. Thus, an angular error is substantially eliminated and displacement of the printing plate is small. Then, the pushing portion positions the printing plate in a direction perpendicular to a direction in which the surface plate can be moved. Then, movement of the surface plate positions the printing plate in the direction in which the surface plate can be moved.
