UNIT FOR MOUNTING MARKER

摘要

PROBLEM TO BE SOLVED: To provide a unit for mounting a marker such as an RAS marker, the unit allowing a precise detection of a detection reference unit.SOLUTION: The unit 1 for mounting a marker includes a lamination structure of an upper substrate 10 and a lower substrate 11, the upper substrate 10 having a through-hole 102, the lower substrate 11 having a convex part 112 as the detection reference unit in a position of the upper substrate 10 which corresponds to the through-hole 101, the convex part 112 of the lower substrate 11 being inserted in the through-hole 102 of the upper substrate 10, and the upper surface 112a of the convex part 112 of the lower substrate 11 in the lamination structure being located at a height lower than the height of the upper surface of the upper substrate 10.SELECTED DRAWING: Figure 1
