The storage element is a set of mechanically moving diaphragms (4) or groups of binary coded holes. At least one remotely or key controlled signalling lamp (2) of a program sensor projects through the diaphragms (4) or groups of oles a bit pattern corresponding to the coding. It is received in an optoelectronic reader (10-12) which decodes it into a voltage stage corresponding to the coding. Preferably the reader has a group of photoelements (10), switching each an electronic switch (11), on light infringement. The elements (10) from a D/A converter, together with a resistor matrix (12). the code selected voltage feeds burning voltage to capacitive diodes. |
