Claim Text:
1. A photoelectric conversion device comprising: a circuit board; a plurality of light emitting modules mounted on the circuit board; a plurality of light receiving modules mounted on the circuit board and being apart from the light emitting modules; and an optical coupling lens part mounted on the circuit board and comprising a first mounting surface, a second mounting surface perpendicularly connected to the first mounting surface, a reflection surface oblique relative to the first mounting surface and the second mounting surface, a plurality of first converging lenses, and a plurality of second converging lenses, the first mounting surface defining a first recess, the first recess having a first optical surface at the upper part thereof, the first mounting surface having a plurality of peripheral edges, each of the peripheral edges of the first mounting surface defining a receiving groove being apart from the first recess, the receiving grooves extending along the respective peripheral edges of the first mounting surface, the second mounting surface defining a second recess, the second recess having a second optical surface at the left part thereof, the first converging lenses formed on the first optical surface, the second converging lenses formed on the second optical surface corresponding to the first converging lenses, the optical coupling lens part mounted on the circuit board, the first converging lenses aligned with the light emitting modules and the light receiving modules, the reflection surface configured for reflecting light beams from each of the first converging lenses toward the corresponding second converging lens and reflecting light beams from each of the second converging lenses toward the corresponding first converging lens, wherein each of the receiving grooves comprises a plurality of first receiving portions and a second receiving portion perpendicular to each of the first receiving portions, the first receiving portions are spaced from each other, the second receiving portion communicates with the first receiving portions, and the first receiving portions are nearer to the first recess than to the second receiving portion.
