1. Omnidirectional optical scanning apparatus for scanning bar coded labels, comprisingan elongated scanning window at which said labels are presented in random orientation,optical means for generating a beam of light,optical means arranged with respect to said generating means for deflecting said beam of light along a line in a given plane intersecting the plane of said scanning window at a predetermined angle to the longitundinal axis of said window,optical means interposed between said deflecting means and said scanning window for dividing said deflected beam of light along said line into scanning segments and offsetting said segments with respect to each other intersecting the plane of said scanning window at the same predetermined angle for producing a multiple of scans across said scanning window, andoptical means intercepting a portion of said deflected light beam scanning segments and reflecting the intercepted scanning segments over to and intersecting the other scanning segments within said scanning window.
