Abstract
A conveyor apparatus used in a copying apparatus of the type using separate diffusion transfer photographic materials, and a photosensitive material in the form of a roller contained in a magazine which is withdrawn and cut to a predetermined length to form a photosensitive sheet. A latent image is created in the photosensitive sheet by exposing it using a light source, and an image-receiving material in the form of a sheet is superposed under the exposed photosensitive sheet. A positive image is formed on the image-receiving material using a diffusion transfer processing. The image-receiving sheet is withdrawn from a cassette wherein a stack of image-receiving sheets are contained. The conveyor apparatus includes feeding rollers disposed in front of the cassette for feeding the image-receiving sheet to a superposition station of the apparatus, an extracting roller for extracting an uppermost image-receiving sheet in the stack and transferring it to a position between the feeding rollers so that it is nipped by the rollers, and a sensor for detecting the image-receiving sheet nipped between the feeding rollers to cause withdrawing rollers to rotate so as to withdraw the photosensit…
