ABSTRACT:
An improved hand stamp for numbering, dating, etc. is provided. The stamp has printing belts, a shaft and a plurality of polygonal members. The shaft has a protrusion along the entire length, and the polygonal members have a through-hole and a plurality of grooves on the circumferential surface of the through-hole such that the position of the polygonal members may be fixed by an engagement between the protrusion and the grooves. The printing belts are rotated by a rotation of the polygonal members about the shaft against the engagement between the protrusion and the grooves.
