1. In a system for electro-optically reading indicia having parts of different light reflectivity, a scanning head comprising:

  • a) a hand-held, generally gun-shaped housing having a hollow handle sized to fit in a hand of a user, said handle extending away from the housing along a handle axis to a handle end and having a predetermined cross-sectional dimension, said housing being movable relative to an indicium within a range of working distances;

    b) a DC voltage-powered, solid-state light source mounted in the housing, for directing a light beam away from the housing toward the indicium for reflection therefrom;

    c) a sensor for detecting light of variable intensity reflected off the indicium over a field of view, and for generating a signal indicative of the indicium;

    d) means for automatically scanning at least one of said light beam and said field of view;

    e) decode control means for decoding the signal, and for controlling the automatic scanning, said decode control means being mounted on a printed circuit board insertable and accessible through the handle end for mounting in the handle;

    f) an electrical connector;

    g) one of the printed circuit board and the electrical connector having electrically conducting pins extending along the handle axis,and the other of the printed circuit board and the electrical connector having electrically conducting sockets extending along the handle axis;

    h) a battery pack for supplying DC voltage to the light source, the sensor, the scanning means and the decode control means through the electrical connector and the printed circuit board; and

    i) a mounting assembly for securing the battery pack and the electrical connector to the handle, said assembly including a casing on which the electrical connector is mounted, said electrical connector and said casing being respectively electrically connected by receiving the pins in the sockets and mounted by movement solely in one direction along the handle axis on the handle to close the handle end, said electrical connector and said casing being respectively electrically disconnected by removing the pins from the sockets and demounted by movement solely along the handle axis in a direction opposite to said one direction to open the handle end, said casing having an insert portion extending only along the handle axis and insertable through the open handle and within the handle along the handle axis and a uniform cross-sectional dimension the same as said predetermined cross-sectional dimension.
