Key duplicating machine

A machine for duplicating keys, comprising:

• a clamp configured to block at least one flat key to be copied, wherein said clamp defines a resting plane for said key;
• a reading assembly for reading the cuts of said key;
• a cutting tool for reproducing said cuts on a blank key, wherein the reading assembly comprises:
• a support bearing a feeler element, wherein said feeler element is movable, with respect to said support, along a first reference direction (Y) parallel to said resting plane, said feeler element comprising a reading end contacting said original key at said cuts;
• elastic means interposed between said support and said feeler element, wherein said elastic means push said feeler element away from said support so that said reading end is in contact with said cuts;
• a position sensor configured to detect the position, or the change of position along said first reference direction (Y), of said feeler element with respect to said support, said position sensor being electrically connected to a control unit of said machine,
• wherein a component, selected from said support and said clamp is movable along at least a second reference direction (X) orthogonal to said first reference direction (Y) and parallel to said resting plane and wherein, during the movement of said component along said second reference direction (X), said reading end is constantly in contact with said cuts, so as to follow the shape thereof, and said position sensor continuously detects said change of position along said first reference direction (Y), said change of position being determined by said shape of said cuts.
