The invention relates to a hand embossing device for the arranged actuating member in embossing itself of characters in a band, in the housing 35 of which can be actuated in a known manner. The embossing tool that Band by a mating member in resilient system pairs 28 are on the circumference of a dial 32 anmit a feed roller is held, which is arranged by a, which is rotatably provided in the housing 12 so the actuation triggering the embossing process is that any pair of tools is sent to the embossing station Lever-mounted pawl on return of the 26 for embossing certain characters in the band 14 The actuating lever can thus be moved step-by-step to the starting position. The dial 32 has an upper one is rotatable that the pawl through the loading and lower disc 34 and 36, one of which is the Operating lever supported one end of one with its male dies and the other the dies of the tool on the other End in the housing supported screw pairs carries.
