发明名称 Instant processing film unit
摘要 An instant-processing film unit of the preregistered type is adapted for use in commercially available adapters for professional type cameras. The film unit includes a photosensitive element for recording a processable latent image, a cover sheet for facilitating the distribution of a processing composition over the element, and an internal dark slide removably positioned between the photosensitive element and cover sheet for shielding one side of the element from premature exposure. The dark slide extends from between the photosensitive element and cover sheet through an opening at one end of the film unit, and is provided with an opaque hood which is attached to the dark slide and encloses the opening to protect such end from light leaks.
