摘要：The present invention provides an optical information reading apparatuscapable of producing uniform and bright illumination light and of projecting the
illumination light onto an appropriate position on an object of reading at all times. In theapparatus, a light-receiving optical system including a light-receiving sensor and an image
formation lens is provided and illumination optical systems each including an LED and anillumination lens device are placed on both sides of the image formation lens. Theillumination optical systems are integrally connected to each other through a connectingportion to form a lens-connected assembly. In an incident surface of the illumination lensdevice, a plurality of convex lens tiers and a plurality of concave lens tiers are alternatelymade smoothly to form a multi-tiered lens surface, and an output surface thereof ismade into a gentle cylindrical configuration to form a rod-like lens surface.
