Abstract
Barcode scanning device () includes a rotatable polygon mirror () and a first fixed reflection mirror (). The polygon mirror () comprises a first reflection surfaces (c), (e) and a second reflection surfaces (a), (b), (d), (f). The first reflection surfaces (c), (e) reflect laser light and thus emitting first scanning light in a range of ±20° with respect to an optical axis (). The second reflection surfaces (a), (b), (d), (f) reflect laser light and thus emitting second scanning light in a range larger than ±20° with respect to an optical axis (). The first fixed reflection mirror () reflects the first scanning light and second scanning light forming scanning patterns in an object readable area. These scanning patterns are composed of a plurality of second scanning lines each parallel with other and first scanning lines disposed between the second scanning lines.
