ABSTRACT OF THE DISCLOSURE Longitudinal grooves and/or ribs (2a,2b,2c) depart from the card's (1) forward extremity (1a), likewise two similar rows of toothing (3) occupying a limited portion of the card. The obliterator is furnished with a slot (30) accessible from without, whose cross-section complements the card's transverse profile and whose two longitudinal grooves (32a,32b) serving to accommodate the said tooth- ings (3) give place to teeth of corresponding small cog- wheels (36a,36b) idling on respective shafts. Insertion of the card (1) into the slot (30) causes gear-pairing of the cogwheels (36a,36b) with the toothings (3), intercep- tion, or not, of mechanical tracer points (24,25,33,34,37) linked with corresponding micro-switches (24a,25a,33a,34a, 37a), with predetermined areas of the card, with consequent excitation of an electromagnet (16) commanding a blade (19) which clips a paring (Z) from the card's (1) forward extre- mity (1a) ;the number of clippings equates to the number of teeth (3a) in each of the card's toothings and the final clipping may be effected only when individual micro- switch (34) is inserted into the corresponding aperture (45) located within the card itself. Each accomplished clipping occasions activation of a corresponding micro-switch (18a) which in turn activates a drinks/services vending unit (50).
