ABSTRACT:
A printing apparatus has a holder which incorporates a permanent magnet and has a printing element or elements containing magnetically soft material.
In use a printing element is held against a thin positioning portion by the attraction of the permanent magnet. To engage a printing element the printing element is placed in contact with the positioning portion and the permanent magnet is brought up to the positioning portion. To release a printing element the permanent magnet is moved away from the positioning portion.
Printing elements may be aligned printing-face down in an aligning member. The printing elements have depicted on the face opposite the printing surface the character on the printing surface.
In one version a printing apparatus is used as a hand-stamp, and in another version a printing apparatus is inked and used by hand-rolling.
