发明名称 Sketching aid
摘要 A sketching aid is provided which includes an opaque frame mounting a rigid transparent plate, and having a slide arrangement allowing a transparent drawing film to be moved into face-to-face contact with the plate. A supply of transparent drawing films may be stored within the frame hand-held portion and a common pivotal blocking member can prevent sliding of the films out of the storage compartment and from engagement with the plate. The plate and frame may be coplanar, or may be pivoted together so that they are movable from the face-to-face position to a position wherein an angular relationship is provided. A resting bar may be adjustably mounted to the frame, facilitating support of the frame on a resting surface, and may have a drawing implement holding portion formed with it.
