Abstract

1,235,748. Sensing records. ELEKTRONISCHE RECHENMASCHINEN VEB. 11 Dec., 1968, No. 58980/68. Heading G4M. The operation of photo-cells sensing a record is monitored by supplying the photo-cell outputs to an AND or OR gate having its output connected to a circuit with a variable threshold. The AND gate monitors during gaps between records and the OR gate monitors the sensing of a record.
