摘要： PROBLEM TO BE SOLVED: To enable correct reading of image data according to the characteristics of an original image, even if the original image includes a very highly lustrous image such as an image of a metallic color. SOLUTION: A light of a light source 20 is guided to a first irradiation direction A1 and a second irradiation direction A2 to irradiate an original 10 with the guided light, and a reflection light reflecting from the original in a predetermined reflection direction C is guided to a CCD unit 50 for performing photoelectric conversion, so that image data is obtained. At this time, the intensity of light in the irradiation direction A2 is adjusted so as to be weaker than the intensity of light in the irradiation direction A1 by optical amount adjusting means 21, 22 provided on optical paths to the irradiation directions A1, A2, and the direction of light reflection is switched between the directions A1 and A2. Moreover, the image data of the original are composed on the basis of two types of the image data generated from the reflected light of the light of each of the irradiation directions A1 and A2.

摘要： PROBLEM TO BE SOLVED: To prevent timing to write an image on a photoreceptor from becoming incomplete be to of staining of polygon mirror. SOLUTION: In this optically scanning optical device where a laser beam is deflected by the polygon mirror 5 so as to perform scanning and expose the photoreceptor 8, a reflecting mirror for a sensor 9 and a photosensor 10 are arranged corresponding to the back within a deflecting scanning range. The timing for writing image on the photoreceptor 8 is decided, based on a counted value set by each deflectingly reflecting surface of the mirror 5 by counting a reference clock from the time of the laser beam reflected by the front deflecting reflection surface of the mirror 5 being detected.

摘要： PROBLEM TO BE SOLVED: To provide a document reader capable of preventing deterioration of image quality by maintaining balance of colors of a read document image even if the temperature of the document reader changes, and to provide an image forming apparatus equipped with the same. SOLUTION: The document reader 2 equipped on the image forming apparatus 1 causes a document reading section 11 including a light source, an imaging element and an image forming lens to read a document for each of a plurality of colors, e.g. three colors of red (R), green (G) and blue (B), and causes an original image processing section 14 to process the read document image. The document image processing section 14 processes the document image on the basis of the temperature of the document reading section 11 to be detected by the temperature detecting section 15 so that an evaluation value for evaluating a deviation amount between the focusing position of the image forming lens for the plurality of colors read by the document reading section 11 and the light-receiving position of the imaging element may be included within a predetermined range using an evaluation value for one of the plurality of colors as a reference.

摘要： An embodiment of the present invention involves a document reading apparatus that includes an optical scanning unit that moves back and forth in a document reading direction so as to read information of a document placed on a document placement table arranged in a top face of a frame by irradiating the document with light emitted from a light source lamp, and a distribution cable connected to the light source lamp. The optical scanning unit includes a support member that leads out and supports the distribution cable connected to the light source lamp in the document reading direction, and the support member includes a regulating member that regulates inclination of the lead-out distribution cable with respect to the document reading direction to support the distribution cable so as to be substantially parallel to the document reading direction.
