INFORMATION-READING COMPONENT AND INFORMATION-READING DEVICE UTILIZING SAME

摘要

An information-reading element may be provided, which can be made small, and allows the number of adjustment steps to be reduced, and an information-reading device may be provided. An information-reading element may be provided and equipped with a light-emitting element, which serves as a polarized light-emitting part for emitting polarized light as outgoing light, and a light-receiving element, 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, said reflecting plate being a target object from which information is to be read, wherein the light-emitting element and the light-receiving element have different polarization characteristics from each other.

主权项

1. An information-reading element comprising:
a polarized light emitting part emitting polarized light as outgoing light; and a polarized light receiving part receiving as returning light the outgoing light reflected on a read object as an object from which information is read, the polarized light emitting part and the polarized light receiving part respectively having different polarization characteristics.
