    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.

    摘要: An object is to provide an imaging optical system having a very simple structure that can read image while maintaining excellent image quality without suffering from significant asymmetrical aberrations. An imaging optical system for image reading is adapted to form an image of image information on a surface of an original onto a line sensor while changing a relative position of the original surface and the line sensor to allow the line sensor to read the image information. The imaging optical system includes two off-axial reflecting surfaces, and the two off-axial surfaces are a plus deflecting surface and a minus deflecting surface, or a minus deflecting surface and a plus deflecting surface disposed in the mentioned order from the original surface side, where an off-axial reflecting surface that deflects a reference axis beam clockwise is defined as a minus deflecting surfaces and an off axial reflecting surface that deflects the reference axis beam anticlockwise is defined as a plus deflecting surface.
