Arrangement for blocking a data support in a data exchange device

摘要

The arrangement has a blocking unit (80) moved elastically towards a blocking position by a spring (82). A control unit (46) is mounted in a longitudinal translation with respect to a case between back rest and extreme front positions of the blocking unit. The control unit is mounted with respect to the blocking unit to provoke automatic blocking of a data medium, when the control unit reaches its front position.
