摘要

The invention relates to a system for replacing the carriages by avoiding overflows of files. It consists of a known consigner box (1), equipped with a lock (5) of varied shape. It also consists of a key (3) equipped with a polarizer (6) in adequacy with the shape lock (5). The unlocking of the deposit will only occur if the lock and the keying are identical. If this is the case the user can engage the key in the bottom of the race and get his instructions, otherwise the race will be stopped by the inconsistency of the profiles of the key (6) and the lock (5). The user will have to bring the carriage in the queue having the same form of lock as that equipping his carriage, each file having a different lock.
