  • Patent number: 5036355
    Abstract: An auxiliary camera/projector is mounted on one side of an automatic step-and-repeat camera to obtain a template film image and project it onto the subject holder to provide a visual guide for properly positioning copy which is to be photographed by the step-and-repeat camera. The auxiliary unit has a film holder which latches into place and which includes removable opaque panels in front of and behind the film. When the camera/projector is being used to photograph the template, the front panel is removed for exposure of the film to the template image. After the exposed film has been processed, the film holder is replaced in the camera/projector and both opaque panels are removed for projection of light through the film and onto the subject holder.
