Abstract:
An arrangement for selectively electro-optically reading one-dimensional and two-dimensional symbols, comprising:a) a support; b) a first, selectable light source on the support for producing a first light beam having a generally elliptical cross-section; c) a second, selectable light source on the support for producing a second light beam having a generally circular cross-section; d) means for detecting whether a symbol being read is one-dimensional or two-dimensional, and for selecting the first light beam when a detected symbol is one-dimensional, and for selecting the second light beam when the detected symbol is two-dimensional; e) a scanner on the support for sweeping a selected beam over the detected symbol for reflection therefrom; and f) a sensor on the support for sensing light reflected from the detected symbol and for generating an electrical signal corresponding to the detected symbol.
