    • PROBLEM TO BE SOLVED: To provide an indicia reader capable of reading indicia of proximally and distally located targets by a single traction trigger.SOLUTION: A multiple range indicia reader 112 comprises: a proximal laser generator 288 which generates light beam for scanning an indicium on a target T located near the indicia reader 112; a distal laser generator 312 which generates light beam for scanning an indicium on a target T located far from the indicia reader; a single traction trigger for activating the proximal/distal laser generators; a scan mirror 292 for directing light beam to the target T; a photo diode 300 for converting the light reflected from the target T into an output signal; and a decoder for decoding indicia information derived from the output signal. An operator activates selectively the proximal/distal laser generators by the single traction trigger.
    • 要解决的问题:提供能够通过单个牵引触发器读取近端和远端定位的目标的标记的标记读取器。 多范围标记读取器112包括:近端激光发生器288,其生成用于扫描位于标记读取器112附近的目标T上的标记的光束; 远端激光发生器312,其产生用于扫描远离标记读取器的目标T上的标记的光束; 用于激活近端/远端激光发生器的单个牵引触发器; 用于将光束引导到目标T的扫描镜292; 用于将从目标T反射的光转换为输出信号的光电二极管300; 以及用于解码从输出信号导出的标记信息的解码器。 操作员通过单个牵引触发器选择性地激活近端/远端激光发生器。 版权所有(C)2012,JPO&INPIT
