Abstract
A scanner can read machine-readable code on an object. A scanner has a scanning device, a data device, and a registration device. The scanning device can repetitively scan the code and provide a scan signal repetitively corresponding to at least fragments of the code. The data device is coupled to the scanning device and responds to its scan signal for repetitively storing it. The registration device is coupled to the data device for reconstructing the code from at least two of the fragments of the code by relatively shifting the code fragments until they are in registration.
Claims13
An improved scanner of a type having scanning means for repetitively scanning a code and for providing a scan signal repetitively corresponding to at least a fragment of said code;
- clock means for generating counts;
- storage means for repetitively storing said scan signal;
- and a processor for combining successive scan signals into an extended scan signal cluster;
- the improvement characterized by:
- said scan signal comprising a series of stored counts, each of which corresponds to a transition between code elements;
- and
- said processor further comprising:
- means for comparing stored counts from successive scan signals;
- means for detecting matching portions of compared counts;
- means for combining successive counts having matching portions into the extended scan signal cluster;
- and
- means for decoding said cluster.
