Image read/write head, and image processing apparatus incorporating the same

An image read/write head comprising:

• a substrate having a first widthwise side portion, a second widthwise side portion, and an upper surface carrying a row of light-receiving elements longitudinally of the substrate;
• an elongate case mounted to the upper surface of the substrate to enclose the light-receiving elements;
• a transparent cover mounted to an upper surface of the case for contact with a document to be fed;
• a light source disposed in the case for illuminating the document;
• a lens unit disposed in the case for causing an image of the document illuminated by the light source to be formed on the light-receiving elements;
• and
• a row of printing elements carried by the upper surface of the substrate;
• wherein the first side portion of the substrate has an excess portion extending beyond a lower edge of the case and located outside the case;
• wherein the row of printing elements is located on the excess portion of the substrate outside the case;
• and
• wherein the lens unit is inclined toward the second side portion as the lens unit extends away from the substrate.
