摘要 PROBLEM TO BE SOLVED: To provide an optical information reading apparatus capable of positioning two lenses adopted as a focusing optical system at high accuracy and with ease.SOLUTION: A first lens 51 (one of the lenses) of the first lens 51 arranged on an information code c side and a second lens 52 arranged on the light receiving sensor 28 side as the focusing optical system 50 has a supporting unit 54 for supporting the second lens 52 (another lens) from the outer periphery side so that optical axes L1, L2 of both lenses 51, 52 match formed integrally to a lens body 53. In addition, the first lens 51 and the second lens 52 respectively have contact surfaces 55, 56 formed coming into surface contact with each other when the second lens 52 is supported by the supporting unit 54.
