Abstract
Disclosed herein is an optical image sensor device comprising a light source; a first printed circuit board (PCB) having a first through hole for accommodating the light source; a directional light unit configured to progress a light from the light source through a total refraction, and configured to converge light deviated from the total reflection by an object having biometric information when the object is placed to be adjacent to the directional light unit in a predetermined area, and emit it outside thereof; and an optical sensor between the first PCB and the directional light unit to receive the light emitted from the directional light unit.
