ABSTRACT:
A bouncing ball scanner is described which is a ball driven in a reciprocal motion for reflecting image-bearing light onto a photosensitive medium. The image-bearing light can be dictated by a computer, in which case the photosensitive medium may be film for a printed output, or the image-bearing light may be reflected from a subject having an image imprinted thereon, and the photosensitive medium may be a charge coupled device where the image is being read into a computer. The bouncing ball scanner comprises a ball being driven in a reciprocal motion by electromagnetic forces acting thereon. The motion of the bouncing ball is substantially linear in each direction so as to allow ease of calculation of ball position thereby ease of knowledge of pixel position on the photosensitive medium.
