Abstract:
An optical module 100 includes an optical path unit 101 including a plurality of reflectors 104 for securing an optical path of reflected light from a manuscript, an image processing unit 102 including a reading device 105 which reads image information on the manuscript based on the reflected light from the manuscript entered via the optical path, and a connecting component 103 which connects the optical path unit 101 and the image processing unit 102 so that their positional relation will become a prescribed state.
Abstract:
PROBLEM TO BE SOLVED: To provide an image reader capable of preventing flare light from getting into a reading means, making illuminance distribution constant with easy operation so as to align a peak light quantity position of the illuminance distribution with center of a reading area, and reading a clear image; and to provide an image forming apparatus equipped with the same. SOLUTION: A shielding member 42 isolating an original illuminating part 56 and an image reading part 54 is provided in a housing 41 so as to demarcate a second space 58 in which the image reading part 54 is housed, and reflection parts 48 and 49 for irradiating an irradiation area W1 of an original P with light from an LED unit 44 are provided on an upper surface of the shielding member 42, then a long-length slit 59 extending in a main scanning direction so as to guide the light reflected from the original P from a first space 57 to the second space 58 is provided thereon. Projections 67 fit in a groove 66 of the housing 41 and performing positioning of the original illuminating part 56 and the image reading part 54 are provided at both ends in a main scanning direction of the shielding member 42.

Abstract:
A light projection unit includes a substrate, a plurality of light emitting elements arrayed on the substrate in a main scanning direction and including light emitting surfaces, a light guide facing the light emitting surfaces to direct light projected from the light emitting elements onto an illumination target and including a first positioning portion, and a holder including a second positioning portion that engages the first positioning portion of the light guide to position the light guide on the holder. The first positioning portion of the light guide is positioned between centers of light emission of adjacent light emitting elements in the main scanning direction of the substrate when the first positioning portion engages the second positioning portion of the holder.
