Abstract

PURPOSE:To detect accurately only a label of a specific code system by counting the number of all bars up to the last scanned bar of a stop mark after detection of a start mark. CONSTITUTION:When the scanning for a start bar code is completed, pulses are generated from start signal generation source 1 to set FF 5, and the input terminal of AND gate 6 reads out 1 of bar codes. Consequently, pulses are outputted successively by strobe signal generation source 2 at the scanning completion for numeric information and the bar code for the stop mark after that and are supplied to counter 4 through gate 6. In this process, counter 4 counts the number of bars after information bar codes at the completion for the last bar code constituting the stop mark. An output is generated from coincidence circuit 8 at the counting time of this number, and the signal from stop signal generation source 3 is outputted simultaneously, and output terminal 9c of AND gate 9 reads out 1, and it is confirmed that the bar code of a scanned label is a code of the code system entered in setting equipment 7.
