摘要

A stamp unit capable of preventing ink from leaking out of the stamp unit is disclosed. The stamp unit includes a skirt member attached to an ink impregnated body. The skirt member has a substrate formed with a through-hole at its center. A pair of first guides and a pair of second guides are provided on the substrate for guiding corresponding edge portions of a stencil sheet. The first guides extend in a lengthwise direction of the substrate, and the second guides extend in a widthwise direction of the substrate. A pair of third guides are provided on the substrate outside of the second guides. The third guides guide corner portions of the stencil sheet so as to position between the second guides and the third guides. The corner portions guided by the third guides have corners with sharp crease.
