Abstract: In an image reader that can adjust a distance between a platen glass and a close-contact-type image sensor (CIS) without disassembly, a CIS unit includes a CIS and a resilient body which biases the CIS toward the platen glass. A CIS roller holder includes a spacer, and a CIS holder which holds the spacer movably in the vertical direction as well as in the sub scanning direction with respect to the platen glass and is fixed to the CIS unit. Irregularities are formed on surfaces of the CIS holder and the spacer which face each other and are engageable by fitting. When the CIS unit is moved in the sub scanning direction and the CIS roller holder is brought into contact with one rib ,the CIS roller holder is brought into contact with the spacer at projections or recesses, thus changing a distance between the platen glass and the CIS.

Abstract: 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: A scanning module of the present invention includes a light source for illuminating a document. Light reflected by the document is incident to a first and a second mirror provided in a pair. The two mirrors reflect the light a plurality of times therebetween and then output it as light reflected from the first mirror. Subsequently, a third and a fourth mirror sequentially reflect the light along a path including a lens. A fifth mirror reflects the light incident thereto from the lens. A linear sensor is spaced from the fifth mirror by a preselected distance such that the light passed through the lens is focused on the linear sensor. The first and second mirrors are adjustable in position on a path, extending from the document to the first mirror, while maintaining a positional relation therebetween.
