ABSTRACT:
Device for reading magnetic codes borne by carriers such as cards of a specified thickness and optical codes printed on carriers of smaller thickness, characterized in that it includes, mounted in opposite walls (2,3) of a common slot with a width slightly greater than the thickness of a magnetic card, a magnetic reading head (5) associated with elastic means (6) for applying the magnetic head (5) against the magnetic tracks of the card, and an optical reading head (10), means (11;14) for limiting, in the absence of a magnetic card, the engagement of the magnetic reading head into the slot (1) over a part of the width of the latter so as to leave between the magnetic head and the wall of the slot opposite the latter, a gap (B) sufficient for the passage of a carrier of optical codes, and means (11) for recognizing the output signals from the magnetic reading head (5) or from the optical reading head (10).
