Abstract: Provides is a seal surface carving apparatus capable of carving a seal surface using only a single attachment irrespective of a size of a stamp. A porous impression die having a seal surface to be carved is set on a dedicated attachment, and is loaded in a seal surface carving apparatus. A fitting projection fit to a bottom portion of the impression die is formed on the attachment, and impression dice having various sizes may be set. In addition, a slit hole extending in a conveyance direction is formed in an impression die setting portion of the attachment. Impression die size determination means of the seal surface carving apparatus determines a size of the impression die by detecting a position at which the impression die blocks the slit hole.

Abstract: Provided is a stamp unit comprises a case that accommodates an ink occluding member and a frame on which an impression member formed of a porous film is tightly stretched, and a leaf spring is provided between the case and the frame. By an elastic repulsive force of the leaf spring, the impression member and the ink occluding member are constantly separated from each other, and the ink is not allowed to penetrate the impression member during distribution. In this way, even when an unexpected external force is applied to an unprocessed stamp unit, the impression member and the ink occluding member do not come into contact with each other, and penetration of ink into the impression member is prevented from starting.
