ABSTRACT:
A handrest surface of the writing aid is supported on both ends of side supports. Three lockable hinged joints are parallel to each other and the side supports and, when locked, present a rigid handrest surface. When the hinges are unlocked, the handrest surface collapses, allowing the side supports to move inward toward each other. The dimensions of the writing aid in the collapsed or folded position are approximately the same size as a video cassette, allowing efficient storage of the folded writing aid among a collection of video cassettes. Alternatively, a handrest surface of the writing aid is attached to a support locator surface, which in turn has attached to its opposite edge a video cassette support surface. Attached to the opposite edge of the support surface is a locator positioning the video cassette in the writing aid. When both the nested video cassette and the writing aid are grasped in the non-writing hand, the writing hand rests on the handrest surface, improving writing control upon the video cassette edge.
