Abstract

This invention relates to an electronic embossing machine of the type which has a keyboard controlled die head bearing embossing dies. The die head is rotatably displaceable for placement into the embossing position in accordance with which character is to be embossed. Control means is provided so that the rotational displacement represents the shortest distance between the die last actuated and the die selected to be actuated next. The die head is lockable at the selected die position by means of a brake device and a pawl. Detection means are associated with the die head to determine its angular position, under whose effect one of two circuits is closed depending upon the direction of rotation the die head is to take for the shortest distance, in the case where the die which is selected through the keyboard control does not correspond to the die to be located next in the embossing position.
