ABSTRACT:
A read/write copier, including an integrally formed image reading and image printing unit. The copier also includes means for feeding a document to be read in unison with a copy substrate material to be printed past both faces of an integrally formed image reading and image printing unit. The image reading and image printing unit further includes a page-wide linear array of image reading elements located on one of the faces of the image reading and image printing unit, where the reading array is oriented in a direction normal to the direction of travel of the document. Furthermore, the reading elements of the reading array generate image signals representative of the document image scanned, by way of an optical path for each of the image reading elements suitable for transmitting image rays as reflected from the document surface to the image reading elements. Also included on the image reading and image printing unit is a light source to illuminate at least a linear portion of the original document as defined by the optical path of the image reading elements. The image reading and image printing unit further includes a page-wide linear array of image printing elements operatively disposed on another face of the image reading and image printing unit, whereby the printing array is oriented in a direction normal to the direction of travel of the copy sheet and whereby a copy of the document image is produced by the printing elements on the copy sheet.
