Zusammenfassung: | Sensing apparatus includes scanning means for producing electrical signals corresponding to code marks in a code on an article as the code is scanned along a path corresponding to the disposition of the code marks. The code defines a series of digit spaces and each digit space defines a plurality of digit value positions. The apparatus further includes means for generating a corresponding plurality of code-sampling gate signals in each digit space, a code-sampling gate signal being generated corresponding to each digit value position in each digit space, and means for producing an output in response to an electrical signal corresponding to a code mark produced by the scanning means coincident with a code-sampling gate. |
