1. A device for processing binary information marks coded as a series of binary valued marks each mark being represented by the presence of a sensible characteristic of one of two possible values on definite potential data locations which are of equal logitudinal extent on a relatively moving label independently of the then existing relative velocity therebetween said device comprising:

  • a mark sensor for sensing the presence and binary value of said marks when passing thereby and for providing corresponding binary valued electrical mark pulses in response thereto,strobe timing means for detecting the transit time between at least two marks and for thereafter producing successive repetitive electrical strobe mark pulses which are timed to correspond to the expected subsequent occurrences of each potential information mark, anddata register means connected to said mark sensor and to said strobe timing means for accumulating successive binary data values corresponding to the binary value of said mark pulses in time with the occurrence of said strobe mark pulses thereby registering the coded format of said information marks on the moving label.
