Abstract
An image reader comprising a variable magnification system for moving a lens disposed between an image of a document and an image sensor is disclosed. The focus adjustment is performed by moving the image sensor in a direction parallel to an optical axis of the lens. An initializing processing is finished without the focus adjustment in case the image formed on the image sensor is in the infocus condition when the power is supplied to the image reader and the magnification is the equal last magnification.
