    Abstract: Disclosed herein is an improved lens focusing and holding arrangement for an imaging system of the type which may include a photosensor array. The lens may be in contact with a reference surface or surfaces formed within the imaging system housing and may be translatable along the surface in directions toward and away from the photosensor array in order to adjust the focus of the imaging system. A lens retention clip may be provided to secure the lens within the imaging system housing and to cause translational movement of the lens along the imaging system reference surface. When focusing the imaging system, the lens retention clip may be in a first operating condition in which the lens retention clip applies a relatively small force tending to hold the lens in contact with the housing reference surface. After the desired focus has been set, the lens retention clip may be placed in a second operating condition in which the lens retention clip applies a relatively high force tending to hold the lens in contact with the housing reference surface, thus locking the lens in place.

    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.
