Abstract
An optical scanner for optically scanning a bar code includes a housing having a window formed on a selected surface thereof, a first scanning system, housed in the housing, for emitting a first scanning beam from the housing through the window and a second scanning system, housed in the housing, for emitting a second scanning beam from the housing through the window. The first scanning beam moves in a first scanning pattern and the second scanning beam moves in a second scanning pattern which is different from the first scanning pattern. Additionally, the second scanning pattern may be used for scanning a bar code having a selected special form.
