ABSTRACT:
This invention relates to a relatively small printing device for printing onto a printing assembly of the kind having at least one form and an ink transferring ribbon associated with it. The printing device is top loading and includes a flat printing pad and a printing anvil serving as a support for a printing plate, such as a credit card, and for the printing assembly. Also included is an electromagnetic impulse device which has at least one electromagnet and an armature plate connected to the printing anvil and by means of which a short impression impulse is exerted after the distance between the printing pad and the printing anvil has manually been reduced to virtually the distance corresponding to the thickness of the plate and the printing assembly.
