Attachment of a transport ticket validator

摘要

The mechanism has a lock (6) locked at a first position in which a tickets validator is mechanically locked on a support and an access point to data contained in the validator is locked. Unlocking of the validator from the support is authorized in a second position of the lock. The validator is mechanically locked on the support when the access to the data is unlocked in a third position of the lock. The access point is designed as a socket (62) such that the lock actuates a flap for partially closing the socket in the third position of the lock. An independent claim is also included for a system for removably fixing a tickets validator on a support.
