Publication number: 20110042591Abstract: A first bar code that is reproduced by linearly polarized red light (first read light) parallel to a short-side direction and a second bar code that is reproduced by linearly polarized green light (second read light) parallel to a long-side direction are recorded on a birefringence label. A probe is a reading device that reads the first and second bar codes from the birefringence label and includes first and second light sources and an imaging unit. The first light source emits the first read light to the birefringence label. The second light source emits the second read light to the birefringence label at a time different from that of the first read light. The imaging unit captures the birefringence label through a polarizing plate having a transmission axis aligned with the short-side direction of the birefringence label, and acquires reproduced images of the first and second bar codes.Type: ApplicationFiled: August 23, 2010Publication date: February 24, 2011Inventors: Minoru Kurose, Junichi Yokoyama, Yasuhiro Noguchi, Takashi Nagashima, Nobuaki Ueki, Hiroyuki Nagasaki, Ichiro Amimori, Kouki Takahashi
