Abstract

A stamp unit comprising a holding unit, and a method of manufacturing a stamp unit, comprising, holding a stamp material in the holder member to create a holding unit; positioning the holding unit in a stamp manufacturing device so that the holding unit is disposed between a presser unit and an irradiation unit of the stamp manufacturing device; and pressing the holding unit by means of the presser unit so as to force a surface of the stamp material against the irradiation unit to form a desired image on a surface of the stamp material when irradiated by the irradiation unit to thereby create a stamp surface. The height of the holder member is selected in proportion to a size of the stamp material to provide a uniform pressure on the holding unit irrespective of the size of the stamp material. When the holding unit is pressed in the presser unit, a reaction force works on portions of the presser unit and the irradiation unit in proportion to the stamp material size. The reaction force causes portions of the presser unit and irradiation unit to bend. Thus, the height of the holding unit is selected in proportion to the stamp material size so as to absorb the bending or to increase the amount of pressure. Thus, the stamp material can be pressed uniformly in the stamp manufacturing device regardless of the stamp material size ensuring a good quality manufactured stamp surface.
