A hand stamp comprises a casing which in the lower portion thereof has a printing member for producing an invariable text such as the name of a company, a logotype or the like and further houses a printing unit which is vertically displaceable in said casing and comprises a belt with a plurality of separate printing blocks which selectively may be shifted by means of shifting wheels. Said printing unit can be locked in an upper position in which the shifting wheels are accessible for setting through an opening in the casing. A compression spring normally keeps the printing unit in a lower active position in which the printing surface thereof is located beneath the printing surface giving the invariable text to allow said printing unit to make an imprint before the invariable text is printed and with a printing pressure solely obtained by said compression spring. In the lower position of the printing unit the shifting wheels thereof are not accessible through the opening in the casing. |
