Abstract
An optical code reader includes a manually operated focusing distance adjustment mechanism, which includes an electronic memory of a configuration parameter representing the desired focusing distance.
Claims30
An optical code reader, wherein the optical code reader comprises optical and electronic components for acquiring and decoding an optical code and a manually operated adjustment mechanism for manually adjusting a focusing distance for acquiring and decoding the optical code, and an electronic memory storing a value of a configuration parameter representing a focusing distance, which value is available to a user to facilitate adjustment of a desired focusing distance.
An optical code reader comprising a manually operated focusing distance adjustment mechanism, an electronic memory having a configuration parameter representing a desired focusing distance, a user interface and a processor provided with focusing management program code means adapted to cyclically display through said user interface a percentage of successful results of a plurality of reading attempts of a sample optical code, and to detect a current value of a parameter indicating a focusing distance and to store it in said electronic memory upon receipt of a storing instruction when said percentage of successful results is satisfactory.
An optical code reader comprising a manually operated focusing distance adjustment mechanism, an electronic memory having a configuration parameter representing a desired focusing distance, display means and a processor provided with focusing management program code means adapted to display on said display means a value of the configuration parameter representing the desired focusing distance stored in said electronic memory,
- wherein the focusing management program code means is additionally adapted to detect current focusing distance value, to compare it with the value of the configuration parameter representing the desired focusing distance stored in the electronic memory and, when the difference between said two values is not null or greater than a threshold, to provide a mismatch alarm signal.
