1. A scanning system for reading symbols comprising:

  • portable hand-held scanning means for generating electrical signals descriptive of the symbols including manually actuable trigger means for initiating reading of the symbols each time said trigger means is manually actuated by the user when said portable hand-held scanning means is supported by the user;

    said portable hand-held scanning means, further including;

    a housing;

    a light source mounted within said housing for generating a light beam;

    optic means mounted within said housing for directing said light beam along a path towards the symbol;

    scanning means mounted within said housing for cyclically sweeping said light beam across the symbol;

    sensor means mounted within said housing for detecting the intensity of light reflected from the symbol, and for generating an electrical signal indicative of the detected intensity of the reflected light;

    signal processing means mounted within said housing for processing said electrical signal and for generating said electrical signals descriptive of the symbol; and

    handle means for normally supporting said housing in a non-contacting relationsip with the symbol during reading thereof when said scanning means is supported by the user, said manually actuatable trigger means being disposed in said handle means;

    fixture means for receiving and supporting said portable hand-held scanning means and including a head portion and a base portion, said hand-held scanning means being supported by said head portion a predetermined distance above said base portion to allow objects bearing the symbols to pass between said head portion and said base portion;

    said scanning means housing is generally handgun-shaped and said handle means is dimensioned to be gripped by the hand of a user and wherein said housing further includes a barrel portion connected to said handle portion, said barrel portion being received by said head portion of said fixture means; and

    said fixture means further including means interconnected to said portable hand-held scanning means for sensing the presence of an object between said head portion and said base portion and for automatically initiating reading by said portable hand-held scanning means of the symbols without actuation of said manually actuatable trigger means each time said sensing means senses the presence of an object when said portable hand-held scanning means is supported by said fixture means.
