Patent ID: 7954427

Claim:
A rotary stamp with master stamp comprising: a rotary stamp in which an endless print belt is stretched between a shaft part of a rotator supported rotatably by a shaft provided on a rotary stamp frame and a bridge part provided on the rotary stamp frame; and a master stamp having a porous fixed print base containing an oblong hole which exposes a desired print section from a plurality of print sections provided along an outwardly facing belt surface of the endless belt of the rotary stamp, with the rotary stamp and the master stamp being built in a grip case, wherein the endless print belt of the rotary stamp is a thin melt-processed laminated belt whereby the print sections are kept in a porous state and a space part between the print sections is treated into a non-porous state, the print section and the space part being created as a result of melt-processing a superficial layer of the space part, whereby the endless laminated belt base is composed of a thermoplastic resin base belt foundation having an infinite number of continuous pores as a front layer and an ink circulation reinforced rear fabric as a rear layer, the oblong hole in the master stamp has a width in the front-forth direction which allows the endless print belt to be rotated such that the outwardly facing belt surface of the endless belt does not make contact with hole edges in the front and back of the oblong hole when the belt is rotated along the bridge part with the print section being exposed through the oblong hole, and a changing of the print section of the rotary stamp that is exposed through the oblong hole is only enabled by a rotating operation of a rotator exposed outside of the grip case.
