摘要： The present invention relates to an optical pointing device for mobile terminals, which can improve assembly efficiency and stability. An optical pointing device according to the present invention includes a holder having an accommodation opening therein. Light emitting means is installed in the accommodation opening of the holder. A condensing element includes a pair of prisms installed in the accommodation opening of the holder and integrated into a single structure so as to condense light emitted from the light emitting means, and a condensing lens disposed between the paired prisms. An image sensor captures light provided through the condensing element and calculates the captured light as displacement values. The condensing element includes a lens holder coupled to the condensing lens so as to maintain stable installation of the condensing lens between the paired prisms.
