摘要：
A multi-head optical scanning device used for a bar code reader having a reduced thickness and realizing more complete 360° bar code reading. The scanning device includes a bottom part (1), a side part (4) which is nearly vertical to the bottom part, a light source (5), a polygon mirror (6) and a light detector (8) contained inside the body of the side part. Light beams are emitted from the light source (5) so that they are nearly vertical to the surface of the bottom part (1), and the polygon mirror (6) has a rotation axis at a position which is nearly parallel to the surface of the bottom part. The optical scanning device eliminates the need for a mechanism which performs scanning inside the bottom part and the degree of freedom with which each of the pattern mirrors is disposed is increased, and provides a scanning pattern whose reading capacity can be upgraded by using a scanning pattern which is emitted from the bottom part (1).
