Wall-mounting image processing apparatus

A wall-mounting image processing apparatus comprising a machine housing mounted on a substantially vertical wall surface, and an image reading/writing head disposed in the machine housing, the image reading/writing head including:

• a substrate having one surface on which a plurality of light receiving elements are arranged in a row;
• a head case mounted on said one surface of the substrate to surround the plurality of light receiving elements;
• a transparent cover mounted to the head case and spaced from the substrate in facing relation thereto, a document being transferred in contact with the cover;
• a light source disposed in the head case for illuminating the document;
• a plurality of lenses arranged in the head case for forming, on the plurality of light receiving elements, an image of the document illuminated by the light source;
• and
• a plurality of printing elements mounted on the substrate in a row extending in the same direction as the row of light receiving elements;
• wherein part of said one surface of the substrate forms an excess surface projecting laterally from the head case, and
• wherein the printing elements are arranged on the excess surface.
