    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).

    摘要翻译： 用于具有减小的厚度和实现更完整的360°读取条形码的条形码读取器的多头的光学扫描装置。 所述扫描装置包括：（8）包含（1），侧部（4），所有这些是几乎垂直于底部分，一个光源（5），多面反射镜（6）和一个光检测器本体内部的底部部分 的侧部。 光束从所述光源（5），以便GDP是可以几乎垂直于所述底部部分（1）的表面上，并且多面镜（6）具有一个旋转轴的位置处的所有其几乎平行于的表面发射 底部。 光学扫描装置消除了对执行的底部部分内扫描和自由的与每个图案反射镜被布置增加的程度的机构的需要，并提供了一个扫描图案是谁的阅读能力可以通过使用扫描图案进行升级 所有这一切都从底部部分发射（1）。
