PROBLEM TO BE SOLVED: To provide an optical information reader having a holder capable of adjusting a relative position by a simple structure and supporting an imaging lens.SOLUTION: An imaging lens 50 includes: a lens body 51 having an outer peripheral surface 55b formed in a cylindrical surface shape around an optical axis L; and a flange 52. On the inner peripheral surface of an insertion hole 60c formed in a holder 60, one side guide parts 61 and 63 and the other side guide parts 62 and 64 are formed for guiding the flange 52 along a predetermined angle α in the state of holding the flange 52 from one side of an optical axis direction and the other side of the optical axis direction. The imaging lens 50 is relatively movably supported along the optical axis L by slide-contacting the respective inner surfaces 61a-64a of the guide parts 61-64 to the outer peripheral surface 55b of the lens body 51. The one side guide parts 61 and 63 and the other side guide parts 62 and 64 are arranged not so as to be overlapped to each other as viewed from an optical axis direction. |
