INFORMATION-READING COMPONENT AND INFORMATION-READING DEVICE UTILIZING SAME

摘要

The purpose of the present invention is to provide an information-reading component, which can be made small and allows the number of adjustment steps to be reduced, and an information-reading device. An information-reading component (10a) equipped with a light-emitting component (11a), which serves as a polarized light-emitting part for emitting polarized light as outgoing light, and a light-receiving component (11b), which serves as a polarized light-receiving part for receiving the polarized light as returning light after the polarized light is reflected off a reflecting plate (13a), said reflecting plate being a target object from which information is to be read, wherein the light-emitting component (11a) and the light-receiving component (11b) have different polarization characteristics from each other.
