Magnetization of Magnetic Ink Characters Marks or Symbols

Magnetic ink characters, marks or symbols are magnetized, for subsequent character recognition, by two sources of magnetism disposed on opposite sides of the document path.

Document 7 translates the magnetic ink characters 9 in the direction of the arrow between the magnets 3, 5, comprising a set of like poles (N), disposed opposite each other, one over and one under the document path. In this manner a strong longitudinal magnetic field is concentrated in the area of the characters, magnetizing them for subsequent recognition.

The document does not contact the poles and because of the symmetry of the field some tolerance is allowable in the distance of the document from the opposed poles.
