Abstract: The improved slit scanning exposure apparatus has a variable slit assembly that is provided in proximity with the exposing zone and which is composed of two slit plates movable independently of each other in synchronism with the scanning speed. The apparatus may additionally have a color filter that can be inserted into the optical path of reflected light from the image on a document in the scanning direction. The apparatus is capable of preventing flare from being admitted through an exposure slit to a light-sensitive material on the exposure position when it is being exposed from light reflected from the document image. In addition, the apparatus enables more than one document image to be edited into a single image and permits the color filter to be inserted into the optical path of reflected light without causing unevenness in colors.

Abstract: An exposure device effects a slit exposure to a photosensitive sheet material moving over an exposure station, and includes two pairs of conveyor rollers disposed on opposite sides of the exposure station. The two pairs of conveyor rollers first convey a photosensitive sheet material forward, passing over the exposure station until one of the two pairs of conveyor rollers holds the trailing end of the photosensitive sheet flat therebetween. Prior to making an exposure, the two pairs of conveyor rollers are rotated in a reverse direction to move the photosensitive sheet back. After the trailing end of the photosensitive sheet is grabbed by the other of the two pairs of conveyor rollers, a shutter is actuated to effect an exposure to the photosensitive sheet with a slit line exposure light while the photosensitive sheet is being moved back, trailing end first.

Abstract: An apparatus for feeding a photosensitive material to an exposure station of a copying machine which makes copies on the photosensitive material from various originals. The apparatus includes at least two magazines, each of which is detachably mounted on the copying machine; at least two photosensitive materials having different sensitivities contained in the magazines, respectively; and a magazine selector for selecting one of the magazines according to the type of original. The magazine selector includes an automatic classifying device for classifying various originals into at least two types.

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.

Abstract: An exposure device for a color copying apparatus having a filter holding frame mounting a filter plate provided with color filter layers and a transparent section and a pair of aperture plates for forming a variable aperture. The filter holding frame is movable in a first direction perpendicular to an exposure light path to selectively place the filter layer and transparent section into the exposure light path. The aperture plates are movable toward and away from each other in a direction perpendicular to the first direction and to the exposure light path so as to vary the size of aperture formed therebetween. Between the filter holding frame and the pair of aperture plates there is a mechanism comprising pins and cam grooves for relative movement of the filter holding frame and the aperture plates.
