ABSTRACT:
A communication apparatus using infrared rays (IR) and capable of receiving an IR signal without regard to its orientation is disclosed. An IR signal incident to the apparatus is transmitted through an IR signal inlet implemented by a one-way mirror. Subsequently, the IR signal is sequentially reflected by reflectors and the IR signal inlet to reach an IR signal receiving portion.
