to the location of the probes and the end part b corresponds to the outlet in the longitudinal scan the microcontroller 5 includes a previously installed internal program or firmware 6 which analyzes the signals processed by said microcontroller 5 providing the result of the operation to the display 7 on which they are shown this display 7 being complemented with a block of buttons 8 the note 2 which is constantly in view of its bearer passes through the device up to the outlet 9 thus proceeding to processing the seized signals thereof the system also includes several note 2 driving means in order to facilitate its longitudinal range a driving which is carried out with the aid of a motor 10 and several pulleys 11 which move mounted wheels 12 for driving there being an inclined wheel 12 u2032 for aligning the note 2 once it has entered into the device and whose alignment consists of shifting and aligning that note 2 on the side edge 13 so that the probes 3 suitably and correctly act the mounted wheels 13 act by means of friction for passing the note 2 through there being mirror wheels in order to facilitate the homogenous driving without damaging the note the system also includes a standard commun ication output with other computer systems with the object of aiding the exchange of data such as updating features to be recognized performing remote tests in the case of a.
