<p>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 toothings (3) give place to teeth of corresponding small cogwheels (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), interception, 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 extremity (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 microswitch (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).</p> |
