PROBLEM TO BE SOLVED: To provide a stamp surface plate-making apparatus that exactly detects a size of a stamp surface material held by a medium holder inserted in the stamp surface print-making apparatus, a method for detecting a size of the stamp surface material, a medium holder, and a method for manufacturing the medium holder.SOLUTION: A stamp surface plate-making apparatus 1 where a medium holder 16 that holds a stamp surface material 18 at the center of a plate-like body and has a notch part 22 at one side end part is inserted into a plate-making insertion part 15 to transport the medium holder 16 to the printing part detects an amount of transportation from the insertion direction tip part of the medium holder 16 to a notch starting end position of the notch part 22 as a first amount of transportation α, and an amount of transportation from a pattern starting end of the notch part 22 to a notch terminating end as a second amount of transportation &bgr;, calculates a longitudinal dimension of the stamp surface material 18 on the basis of the first amount of transportation α, as width dimension calculation means of the stamp surface material 18 on the basis of the second amount of transportation &bgr;, and a plate-making start position to the stamp surface material 18 on the basis of α + &bgr; - γ (constant). |
