Abstract
An instant print slide projector is provided for sequentially displaying a plurality of photographic images on a remote screen one at a time and selectively copying one or more of said images on self-developing photographic print film. In addition to conventional slide projector components, the invention also includes means for holding a pack of instant print film, a camera lens for selectively focusing the image from a transparency on the photosensitive surface of the film, a shutter to normally prevent light from entering the camera lens, and image directing means for intercepting the image and creating an optical path for the same to the film surface. In the preferred embodiment the camera lens and the image directing means are selectively movable between a first position spaced apart from the optical axis of the projector to permit normal projection of the transparency image on the screen, and a second or print position in which the image directing means is juxtaposed along the optical axis to intercept the image, and the camera lens is positioned to focus such image on the instant print film. Means are also provided to actuate the shutter to expose the film upon movement of th…
