An optical reading device for documents endowed with printed and/or perforated surfaces, with at least one CIS (15) equipped with light emitters (19) and detectors (20) and positioned, on one side of a path for the movement of a document with respect to the sensor, for reading, by means of reflection, one side of the document, and means (18, 16, 116, 216, 19) of sending light towards the sensor, arranged in a frontal position with respect to the sensor (15), on the other side of the path for the movement of a document for lighting the sensor (15) through any holes which may be present in the document. Processing means receive the signals from the sensor (15) and obtain images of the perforated and/or printed areas in the document. A detecting method is also described. |
