Abstract: PROBLEM TO BE SOLVED: To significantly reduce the effect of dust on a read original image even if dust is present on the optical path extending from a photoelectric transducer to a main scanning line.
SOLUTION: A control unit 106 averages, for each pixel of interest, white shading levels corresponding to two pixels preceding and following the pixel of interest, and obtains a difference by subtracting the average value from the white shading level of the pixel of interest, and compares the absolute value of the difference (a variation amount of the white shading level) with a threshold value. Then, if the variation amount exceeds the threshold value, the control unit determines that the white shading level has irregularly varied, references the black shading level in a black shading memory 105, corrects the black shading level of the pixel of interest to increase the level in proportion to the variation amount, and updates the black shading level in the black shading memory 105.

Abstract: PROBLEM TO BE SOLVED: To provide an image reader capable of suppressing a deterioration in resolution even though the scanning speed of image reading is increased, and to provide an image forming apparatus. SOLUTION: The image reader 100 includes a CCD 26 and a control part 400. The CCD 26 has three photoelectric conversion parts 261 to 263. The three photoelectric conversion parts 261 to 263 detect light of three colors of RGB respectively and output RGB signals. The control part 400 generates image data by alternately using a first luminance signal based on a G signal outputted from the photoelectric conversion part 262 and a second luminance signal based on an R signal and a B signal outputted from the photoelectric conversion parts 261 and 263 in a sub-scanning direction, when an original is moved at a pixel shifting speed at which a pixel detected by the photoelectric conversion part 262 is shifted from a pixel detected by the photoelectric conversion parts 261 and 263 for the integer multiple of one pixel plus 0. 5 pixels in the sub-scanning direction.

Abstract: PROBLEM TO BE SOLVED: To illuminate an original document so that no shadow occurs for an end part level difference of the original document.
SOLUTION: In an illuminating apparatus, a light axis X of an LED 82n located at a position overlapping with an original document reference line L is in a vertical direction to a main scanning line B when seen from a front direction. In addition, the light axis X of each LED 82(n-1), 82(n-2), ..., on left side from the original document reference line L inclines at a constant inclination angle α to a vertical line orthogonal to the main scanning line B so as to be directed to the original document reference line L when seen from the front direction. In a similar way, the light axis X of each LED 82(n+1), 82(n+2), ..., on right side from the original document reference line L inclines at the constant inclination angle α to the vertical line orthogonal to the main scanning line B so as to be directed to the original document reference line L when seen from the front direction. The LED 82(n-2) irradiates diagonal light from a position closer to the outside of the original document MS to the vicinity of the left side end part, and illuminates the shadow of the left side end part level difference of the original document MS on a surface of an original document presser mat 79 by the light. Thereby, the shadow part becomes bright, and the shadow is almost eliminated.

LED82（n-2）将来自原稿MS的外侧的位置的对角线照射到左侧端部附近，照射原稿的左侧端部电平差的阴影 在原始文件按压垫79的表面上。 因此，阴影部分变亮，并且阴影几乎被消除。 版权所有（C）2011，JPO＆INPIT

Abstract: PROBLEM TO BE SOLVED: To prevent dirt from sticking to a reading opening part and black stripes from being generated in reading an original by arranging an opening/closing cover, to be opened/closed in response to the passage of the original, in the reading opening part.
SOLUTION: When a leading end part of the original P carried on a lower carrier guide board 31 is abutted onto an abutment piece 48, the abutment piece 48 is rotated so as to be pushed-up toward the downstream side of an original carrier direction X by the leading end part of the original P. A rotary arm 45 is rotated in the same direction by the rotational movement. When the rotary arm 45 is rotated, a connection rod 43 is pushed-out toward the downstream side of the original carrier direction X. When the connection rod 43 is pushed-out, the opening/closing cover 41 is moved by sliding toward the downstream side of the original carrier direction X, thereby opening the reading opening part 32a. In the meantime, when the original passes in the lower part of the reading opening part 32a, the abutment piece 48 comes off the rear end part of the original and naturally falls by self weight. Consequently, the opening/closing cover 41 is moved by sliding toward the upstream side of the original carrier direction X, thereby closing the reading opening part 32a.
