SYSTEM FOR READING OUT BAR CODED LABELS

摘要

SYSTEM FOR READING OUT BAR CODED LABELS Bar coded labels are picked up by television camera disposed in n register units respectively. The resulting video signals are written into allotted portions of a writing and reading device through a first multiplexer under the control of a control device. The written video signals are read out from the device controlled by the control device while a scanning direction changes. Then the read signal are successively converted to digital signals which are, in turn, examined if they are regular coded signals. The regular coded signals are delivered to the resistor units through a second multiplexer controlled by the control device.
