The invention relates to an inscription position (BP) of a laser beam controlled in terms of two coordinates and its intensity, whereby one photoelectric barrier-controlled driven pair of feed and pressure rollers (1, 2; 3, 4) each is disposed on the feed end and the outlet end and the credit card (C) is positioned in parallel lateral guide tracks (5, 6) in a manner so as to be ready for inscription. The guide tracks (5, 6) are disposed in a turning mechanism (7) which is disposed between the pairs of rollers (1, 2; 3, 4) together with a transfer conveyor (8, 12) which displaces the credit card (C) between the pairs of rollers (1, 2; 3, 4) to such an extent that it is inserted in a first transfer position from the pair of feed rollers (1, 2) into the guide tracks. In a second transfer position, the credit card is retained only at its edges and is held between the pairs of rollers (1, 2; 3, 4) in such a manner that its entire surface is freely accessible for laser inscription. In a third transfer position, the card can be seized by the pair of outlet rollers (3, 4). |
