OPTICAL POINTING APPARATUS AND PORTABLE ELECTRONIC APPARATUS WITH THE SAME

摘要

Disclosed are an optical pointing device and a portable electronic device having the same, in which external noise light and/or noise light due to diffused reflection or the like is prevented from being introduced into an optical sensor, so that precision of operation can be enhanced and a cover forming a housing can have an improved structure. The optical pointing device includes an infrared (IR) source emitting an infrared ray; a cover having a cover plate transmitting the infrared ray so that the infrared ray emitted from the IR source reach an subject out of the cover plate and a cover frame coupled with the cover plate for supporting the cover plate; an optical unit which is provided in the cover and on which the infrared ray reflected from the subject is incident; and an optical sensor sensing the infrared ray incident thereon from the optical unit; wherein the cover plate comprises a base coupled to the cover frame, and an IR band-pass filter layer provided on one side of the base.
