Abstract: When a roller is moved to an opening of a case by a pressing action to the roller, a cover member on a stamp face rotates such that the stamp face is exposed at the opening. Such a mechanism allows a working state and an off-duty state of a roller stamp to be easily switched between. Also, the cover member covers the opening side of the stamp face before the roller is squeezed out. Such a configuration prevents the stamp face from being accidentally exposed while the roller stamp is not in use.
