Abstract:
An arrangement (10) for an interchange of data between a rigid or semi-rigid data medium (12) in an overall shape of a card and a data interchange device (14), particularly one for reading data contained in the medium, comprising a unit (11, 13, 16) in which the data medium (12) is introduce longitudinally into a housing of the unit in which the data medium occupies a given active position, of the type in which the unit comprises a lever (34) for immobilizing the medium (12) which lever is mounted to pivot (A) between an immobilizing position in which the lever longitudinally holds the data medium (12) in an active position in the unit, and a retracted position in which the data medium (12) can be extracted from the unit, and of the type in which the unit comprises a controlled member (70) for locking the immobilizing lever (34) in the lever's angular position for immobilizing the data medium (12), a finger (82) of which can extend facing a part (84, 86) of the immobilizing lever (34) so as to prevent the latter from rotating from the lever's active immobilizing position toward the lever's retracted position, wherein the immobilizing member is a member is a member that is controlled manually by a first â€œonâ€  push-button (70) mounted to slide between a pushed-in â€œonâ€  position in which the immobilizing lever (34) is locked in the immobilizing position, and an â€œoutâ€  position of rest toward which the lever is elastically returned, and wherein there is a retaining mechanism (104, 120, 118) for automatically keeping the first push-button (70) in the â€œonâ€  position, the release of which is controlled by a second, â€œoffâ€  push-button (94) which is mounted to slide between an â€œoutâ€  position of rest toward which the button is elastically returned and a pushed-in â€œoffâ€  position in which the first â€œonâ€  push-button (70) is free to slide.
