    • A bar code reader having two reading windows, i.e., a bottom window and a side window. An increased number of scanning lines are used for constituting scanning patterns for scanning bar codes, and the arrangement of the optical system is contrived to decrease the whole size of the bar code reader and, particularly, to decrease the depth of the bar code reader. A source of laser light, a splitter for splitting the laser beam emitted from the laser light source into two, a reflection mirror for transmitting one beam from the splitter to a polygon mirror, the polygon mirror which rotates to scan the incident laser beam, a mirror system for emitting the beam reflected by the polygon mirror through the reading window, and a focusing member for focusing the beam reflected by the bar code onto a detector that detects the beam reflected by the bar code, are arranged on the same line in the bar code reader. By using a concave mirror, furthermore, the beam reflected by the bar code is folded back to one detector. The light-receiving surface of another detector is faced downward to receive the beam reflected by the bar code through Fresnel lens and mirror, thereby to decrease the depth of the bar code reader. Furthermore, the beam passage from the reflection mirror goes through the lower surface of the polygon mirror intersecting the axis of rotation of the polygon mirror.
    • 具有两个读取窗口,即底部窗口和侧面窗口的条形码阅读器。 使用扫描线数量增加来构成用于扫描条形码的扫描图案,并且设计了光学系统的布置以减小条形码阅读器的整体尺寸,特别是降低条形码阅读器的深度。 激光源,用于将从激光光源发射的激光束分为两部分的分离器,用于将一束光从分光镜传输到多面镜的反射镜,旋转以扫描入射激光束的多面反射镜, 用于通过读取窗口发射由多面镜反射的光束的反射镜系统,以及用于将由条形码反射的光束聚焦到检测由条形码反射的光束的检测器上的聚焦部件布置在 条码读取器。 此外,通过使用凹面镜,由条形码反射的光束被折回到一个检测器。 另一个检测器的光接收表面面向下以接收由条形码反射的光束通过菲涅尔透镜和反射镜,从而减小条形码阅读器的深度。 此外,来自反射镜的光束通过穿过与多面镜的旋转轴交叉的多面镜的下表面。
