摘要： A document illuminating method and device for illuminating a document with higher efficiency with light emitted from a light source. The method for illuminating a document with light emitted from a light source includes a step of illuminating a document with light produced by combining lights emitted from light sources arranged at least in a first direction and a step of diffusing the light beams emitted from the light sources so that each light beam is diffused to a light bema having a width two or more times the interval between adjacent light sources of the light sources in the first direction. The document illuminating device for illuminating a document with light emitted from a light source comprises light sources arranged at least in a first direction, and an optical system for combining lights emitted from the light sources, illuminating the document with the combined light, and diffusing each of the light beams emitted from the light sources to a light beam having a width two or more times the interval between adjacent light sources of the light sources in the first direction.

摘要： PROBLEM TO BE SOLVED: To provide a luminaire which efficiently illuminates without light emission at an end so that a spread of an optical flux in a sub-scan direction is suppressed and the optical flux in a main scan direction (one-dimensional direction) is made more uniform in an area to be illuminated. SOLUTION: This luminaire is a luminaire for an image reader which forms a scattered light from a manuscript face illuminated by a light source into an image in an image sensor by an image formation lens, reads the image of the manuscript face in one dimension, and shifts it in a rectangular direction to this read direction to repeat this one-dimensional read operation successively, thereby reading a two-dimensional image. The luminaire has an illumination lens having at least a plurality of lenses, and a plurality of optical fluxes outputted by an individual lens of the illumination lens are overlapped on the manuscript face.
