Abstract
A stamp-making apparatus is provided in which a transparent presser plate is arranged such that the presser plate is parallel with a stamp-making object material, an ink ribbon having a stamp image formed thereon is urged against the stamp-making object material via the presser plate, and exposure of the stamp-making object material to light is carried out via the ink ribbon as a mask. A ribbon feeder rolls out an ink ribbon wound around one end portion thereof to a position facing the stamp-making object material, and then rolls up the ink ribbon around another end portion thereof. A relative translation of the presser plate and the stamp-making object material is made toward each other by moving at least one of the presser plate and the stamp-making object material to thereby urge the ink ribbon against the stamp-making object material. A guide guides the ink ribbon when the ink ribbon is fed, to space between the presser plate and the stamp-making object material. Tension of the ink ribbon is regulated in a manner linked to operation of the relative translation of the presser plate and the stamp-making object material made toward each other.
