Abstract

A control network is for use in an automatic banknote or other document validity checking machine, which can be reprogrammed to allow a variety of different notes to be checked. The document concerned can be monitored by laser appts. thickness measurement transducer or other means and this produces a varying signal (V1) as it passes the transducer. This signal is compared with a threshold and the resulting binary output is timed by a clock and compared with a programmed nominal sequence of clock pulses. The logic required comprises an addressing register (10), clock (11), counter (18), nominal sequence store (15) comparator (19) and evaluation network (20). For a different banknote or document the sequence store (15) address register (10) and evaluation network (20) are reprogrammed.
