1. In a scanner whose scanning action is capable of being stopped and started instantly, and having associated therewith a microprocessor for controlling the scanner in its performance of a scanning process, the improvement comprising:

  • scanning means for scanning a target containing indicia to obtain information therefrom;

    initiating means for triggering said scanning means, said scanning means being responsive to a signal from said initiating means;

    first memory means for retaining information transferred therein from said scanning means during a first scan;

    completion indicating means responsive to a signal from said scanning means, for determining that the first scan is completed;

    decoding means, responsive to said completion indicating means, for decoding information from the completed first scan;

    halting means, responsive to said completion indicating means, for preventing initiation of a subsequent scan by said scanning means; and
