摘要： An image reading apparatus in which an original is illuminated with visible light and with infrared light, and in which a lens assembly forms an image of the original on the surface of a reading device such as a CCD. The lens assembly is housed in a lens barrel. A focus correcting device such as a flat glass or resin plate is movably mounted to the lens barrel, so as to correct defocus of the original on the surface of the reading device due to differences in wavelength between the visible light and the infrared light. The lens assembly includes a resin lens which is disposed on a side of the lens assembly nearest to the reading device, and which is mounted in close proximity to the focus correcting device.
