ABSTRACT:
A device for opening and closing a data carrier exit slit. The device includes a mobile door disposed at the level of the slit so as to cover it and a mechanism for raising and lowering the door, so that the door occupies a raised position in which the slit is open, thus allowing the carrier to leave and a lowered position in which the slit is sealingly closed, thus preventing the carrier from leaving.
