A rubber stamp comprising a housing (13, 14), a base plate (12) fixed at one end of the housing and a handle in the form of a knob (15, 16) mounted at the other end of the housing. A stamp block (24) formed by independently-changeable rubber stamp elements carried by endless rubber bands (25) rotatable in the housing, protrudes through an aperture (23) in the base plate (12). To change the stamp block, the rubber band assembly is withdrawn by axial movement of the knob (15, 16) so as to bring the stamp block within the housing, and the rubber bands are then rotated to set a new stamp block within the housing. Rotation of the rubber bands (25) is effected by respective wheels (31) acting through respective sprocket wheels (56) over which the rubber bands pass. The peripheries of the wheels (31) protrude through slots (33) in a wall of the housing. The slots (33) have recesses (36) through which a part of the periphery of the wheel can be observed carrying information indicating the particular stamp element then forming part of the stamp block.
