Abstract:
A bar code reader comprising:a first reading window; a second reading window disposed next to said first reading window and at a predetermined inclination angle with respect thereto; a source of light for emitting an initial ray of light; splitting means for splitting the initial ray of light into a first ray of light following a first optical path from the source of light and a second ray of light following a second optical path from the source of light; rotary scanning means having a plurality of reflection planes in rotation about an axis of-rotation included in the specified plane, said rotary scanning means having the first and second rays of light incident thereupon from different respective directions and reflecting the first and second rays of light therefrom to form first and second scanning beams respectively following the first and second optical paths; first and second reflecting means for guiding the second ray of light to said rotary scanning means; first focusing means for focusing the first reflected scanning beam toward a first detector; and second focusing means for focusing the second reflected scanning beam toward a second detector, wherein the source of light, the splitting means, the rotary scanning means, the first and second reflecting means, the first focusing means, and the second focusing means have a co-planar arrangement with respect to a specified plane.
