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.
