ABSTRACT:
A scanning apparatus comprises a scanner body portion having an internal receptacle within a scan head portion thereof. A scanning control unit is disposed within the body portion separate from the receptacle and has an electrical connection that extends through the body portion to the receptacle. A removable optical module is adapted to engage the receptacle and be connected electrically to the scanning control unit through the electrical connection. The module includes an optical sensor adapted to receive light reflected from the bar code symbology through an opening through the body portion and convert the light into data representative of the symbology. The data is thereby provided to the scanning control unit. The optical sensor may comprise either a one-dimensional charge-coupled device, a two-dimensional charge-coupled device, an articulated laser, or a light emitting diode.
