  • Patent number: 4908742
    Abstract: A portably writing box usable primarily by children during long automobile trips. The writing surface is illuminated by three separate lamp mechanisms arranged along three different edges of the writing surface. Light rays are directed onto the writing surface from three different directions, thereby eliminating shadows that might otherwise be generated by a single light source located only long one edge of the writing surface. The writing box preferably includes a transistor radio on the lid of the box, such that the child can choose between writing on the writing surface or listening to the radio.
