Abstract
An electronic locking device consisting of a lock and key cards and the lock electronics of which has a data storage and which can be coupled with a mobile printer which can be connected to the lock electronics and retrieve data, the locking device having an insert shaft for the key cards in which shaft a card reader is arranged and which shaft is provided at its end with a socket device connected to the lock electronics for a card-shaped coupling element of the printer which can be inserted into the insert shaft and has electrical contacts. For improved protection against unauthorized reading of data, the invention proposes that the coupling element (9) have a key-card code, and that a slide which can be displaced by the coupling element (9) upon insertion thereof be present in the insert shaft (4), which slide can be fixed in position by tumblers which are transferred into the release position in case of a valid key-card code and thus permit displacement of the slide into its end position in which the contacts come into engagement with the socket drive (49).
