A stamp set is provided which includes a stamp base (11) and a flat plate-like stamp plate (12) having a stamp surface (121) at its one main surface. The stamp plate (12) is fixed to a middle of the stamp base (11). The stamp set further includes a pair of antislip elements (13A, 13B) detachably provided at both sides of the fixed stamp plate (12) on the stamp base (11). Each of the pair of antislip elements (13A, 13B) has an antislip surface (131) at its surface side.

A reverse type stamp includes an outer cylindrical body, an inner cylindrical body which is movable relative to the outer cylindrical body, an elastic member that constantly urges the inner cylindrical body in a protruding direction inside the outer cylindrical body, an inversion body which is reversed and returned in synchronization with the relative movement, and a print body which is joined to the inversion body. When the outer cylindrical body is pressed down while the inner cylindrical body stands on a paper surface, the inversion body is reversed inside the inner cylindrical body for an imprinting operation. An ink pad is provided inside a movable container inside a cartridge. The movable container is elastically supported inside the cartridge by a coil spring provided at a rear surface thereof. Since contact between the ink pad and the print body is buffered, the sagging of the ink pad can be prevented.

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.

A device (1) for guiding an ink pad container (2) into and/or out of a receiving space (3) in the stamp housing (4) of a self-inking stamp (5), comprising a drawer-type receiving container (6) for the ink pad container (2) which comprises, on one side, a free access opening (11) for pushing out and/or pushing in the ink pad container (2).

A seal carving apparatus includes a thermal head having a plurality of heat generating elements disposed in lines, and thermal drive control means that performs a control process of selectively and thermally driving the individual heat generating elements while moving the thermal head and a porous material in relative to each other with the thermal head being in abutment with the porous material, thereby forming a seal face on the porous material. The thermal drive control means controls a pulse time width for thermally driving the individual heat generating elements of the thermal head under pulse width modulation control based on gradation image data having a gradation value, thereby forming a seal with a gradation on the porous material.
