Abstract
An image reader for an image-carrying member is provided which includes a light source for illuminating the image-carrying member, a sensor for detecting light coming from the image-carrying member along a predetermined optical path, and an optical system including a lens fixed to a lens holder. The lens holder together with the lens is movable along the optical path for adjusting the focus of the lens. The image reader also includes a shield member for partially blocking the passage of the light coming from the image-carrying member. The lens and the shield member keep a predetermined distance to each other while the focal adjustment of the lens is being performed.
