Abstract

An optically open stacked type subminiature optical device according to the present invention has an independent aperture stop structure to enable designing of a stable small optical device having an optical open cover structure, thus improving optical performance. Further, the optically open stacked type subminiature optical device of the present invention is configured in that the aperture stop structure is assembled with another structure into a stacked structure to establish a stable assembly together with the cover structure, thereby allowing for ease of assembly and improving productivity.

Description

technical field [0001] The present invention generally relates to an optical device installed in a mobile device such as a mobile communication terminal and used as a miniature pointing device or an input device, and more particularly, to an optical mouse suitable for touching an optical opening micro-optical devices used in . Background technique [0002] figure 1 An optical device is shown comprising a lens / lens pipe structure 50 for projecting light emitted from a light source 10 onto an object plane forming a lower surface of the optical device 30; also includes a chip package housing 60 that serves as the outermost cover of the optical device module and doubles as a sensor protection structure and a light receiving aperture on the reflected light receiving lens. The above-mentioned structure of the optical device is designed to be used in a general personal computer mouse. In the optical device having the above structure, the optical device body can intercept light d...
