Abstract
A housing frame includes a recess, a flat seat portion and a frame-shaped seat portion which are positioning units for a spot-like light source, a light conductive bar and a light conductive plate, respectively. The required assembly accuracy can be reliably obtained by fitting the light source, the light conductive bar and the light conductive plate to the predetermined positioning units of the housing frame. A recess and a flat seat portion have a thickness Dsmaller than the thickness Dof a frame forming the positioning unit for the light conductive plate, and the housing frame forms a cavity, an opening of which is directed upward, and in order to obtain the required strength a reinforcing frame is provided. By reducing the thickness of the reinforcing frame, the light conductive plate can be disposed close to a display surface of any electronic product in incorporating the spread illuminating apparatus into any the electronic product.
