ABSTRACT:
A device for image shifting to permit tracing a drawing or other configuration from an original onto a sheet that is positioned at a location shifted from the original. The device includes a mirror which reflects an image onto a reflective surface of a partially reflective or semi-transparent panel, and the viewer then sights through the part-reflective surface so that the line of sight projects the image onto a surface displaced from the original. This provides for amusement and rapid free-hand sketching. The displaced image as viewed remains properly oriented on the sketch paper.
