    Abstract: In an image reading apparatus (1), a plurality of reading sensors (9. 11) extend in a main scanning direction and separated from each other in the main scanning direction so as to be located in a staggered arrangement in which a part of one of the reading sensors (9. 11) in the longitudinal direction faces a part of adjacent one of the reading sensors in a subscanning direction. A first connection member (25) is provided to the part of one of the reading sensors facing the part of the adjacent one of the reading sensors. The first connection member (25) protrudes toward the adjacent one of the reading sensors. A second connection member (27) is provided to the part of the adjacent one of the reading sensors facing the part of the one of the reading sensors. The second connection member (27) protrudes toward the one of the reading sensors. The first and second connection members are brought into contact with each other by being urged by a spring (29).

    Abstract: An original reading unit is provided that is superior in the performance of the adjustment of line sensors. According to the present invention, between a unit base and a transparent original support plate, multiple sensor assemblies are arranged, to form a zigzag pattern, as a first array for reading an original and a second array for reading the original following the first array. Each of the sensor assemblies includes a sensor holder, a line sensor and a focus setup unit. Each of the sensor holders, which serve as fulcrums, are rotatable at a single pivot (a rotation center), along the wall of a unit base that is parallel to the original support plate. When the sensor holders are rotated and positioned at predetermined locations, they are fixed to the wall. The line sensors 51 are held, relative to the sensor holders, in the main scanning direction and in the sub-scanning direction, and are moved in an approaching or separating direction in which the line sensors approach or are separated from the wall and the original support plate. The focus setup units, each of which includes coil springs and spacers, move the line sensors 51 in the approaching or separating direction, and position the line sensors 51 at locations whereat focuses are adjusted.

    Abstract: PROBLEM TO BE SOLVED: To provide an image reading apparatus and an image forming apparatus capable of improving image quality, using a simple configuration. SOLUTION: The image reading apparatus converts a manuscript image read with a reading means into an image signal. The reading means comprises a first and a second reading sensors 9 and 11, disposed in a staggered form so that their longitudinal direction extends along and is separated from a main scanning direction, while a part of the longitudinal direction faces on a sub-scanning direction. One connection member 25 and the other connection member 27, projecting toward the facing reading sensors 9 and 11, are provided at a facing position of the first and the second reading sensors 9 and 11. The one connection member 25 and the other connection member 27 are pressure-welded by being energized by a first spring 26. COPYRIGHT: (C)2005,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To provide a technique for adjusting a distance between an original platen glass and a closely contact image sensor (CIS) without disassembling an image reading apparatus. SOLUTION: A CIS unit 10 is provided with: a CIS 12; and an elastic body 13 for energizing the CIS 12 toward a direction approaching the platen glass 4. A CIS roller holder 20 is provided with a thin plate-like spacer 22 molded in a rectangular shape; and a CIS holder 21 for holding the spacer 22 movably in a vertical direction and a sub-scanning direction for the platen glass 4 and to be fixed on the CIS unit 10. Meanwhile, a concave and a convex which can be mated are formed on a surface where the CIS holder 21 opposes the spacer 22. When the CIS unit 10 moves in the sub-scanning direction and the CIS roller holder 20 abuts on a rib 7a (rib 7b), the convex portion of the CIS holder 21 abuts on the concave portion (convex portion) of the spacer 22, and thus, the distance the platen glass 4 and the CIS 12 becomes the shortest.
