Abstract

A lock cylinder (1) carries a bore (4) passing through the cylinder housing (5), the cylinder core (6) and the key channel (3). A radiation source (9) and a sensor (10) are provided in a rose (8) or in another component surrounding the lock cylinder (1). Electronic signals of different amplitudes are generated by bores (13 to 20) of differing size which are located in the key bit of a flat key (12) and which fade out the beam path in the bore (4) of the lock cylinder. These signals are divided in a receiver (11) into a clock track (21) and a code track (22) by means of two threshold values. The code resulting from this is compared in a comparator circuit (23) with at least one desired code of one or more code stores (26, 27, 31, 32, 33, 34). When the codes correspond, the release of an electromechanical blocking mechanism (25) additionally provided takes place. One code store (26) contains a cyclically activatable sequence of codes (C1, C2, C3), a further store (27) is freely programmable (Cn) after the insertion of a programming key into the lock, and a third store (31 to 34) allows individual direct access to the storage locations (C10, C20, C30, ... Ci) by means of a programming unit (35). <IMAGE>
