Abstract
A document scanning apparatus including a light source, first and second optical scanner systems optically coupled in series, an image forming lens supported on a lens support member including a lens base and a driving system including pulleys and driving wires, for moving the first and second optical scanner systems relative to each other and the lens. For the purpose of re-establishing a predetermined alignment of the first and second optical scanner systems in relation to the lens, such as might become necessary upon a breakage or stretching of a driving wire, for example, the first and second optical scanner systems are each provided with at least one reference point defining hole, and the lens base is provided with corresponding reference point holes. Then in the event that adjustment of the positions of the first and second optical scanner systems becomes necessary, the requisite positional alignment can be obtained by aligning the reference point holes of the first and second optical scanner systems with the corresponding reference point holes provided on the lens base. In this way, factory alignment settings can be quickly re-established in the field.
