STAMP

PROBLEM TO BE SOLVED: To provide a stamp made of a porous stamp material which enables high-accuracy sealing on a limited position while holding a state of an exposed stamping surface.SOLUTION: In a stamp, a slide cover 3 that freely moves up/down under resilience of a return spring 5 is interposed between a gripping tube 2 and a downward section of a stamp body 4 mounted therein. Further a part of the stamp body 4 can be pushed down by external operation, while a lock mechanism 6 for locking elevation movement of the stamp body 4 is prepared in the feed position where the stamping surface on the porous printing unit of the stamp body 4 is pushed down from the lower end opening of the slide cover 3 to the downward position.
