摘要： 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transfer photographic materials, and a photosensitive material in the form of a roller contained in a magazine which is withdrawn and cut to a predetermined length to form a photosensitive sheet.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 The image-receiving sheet is withdrawn from a cassette wherein a stack of image-receiving sheets are contained.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 photosensitive material from the magazine and transport it to an exposure station where the exposing is performed. If the sensor does not detect the image-receiving sheet within a predetermined time, copying operations are suspended.

摘要： 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.

摘要： 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. The cam groove comprises a straight cam section which extends along the moving direction and which is provided to place the pair of aperture blades out of the optical path so as to maintain the maximum size of the variable aperture and an inclined cam section which is provided to bring the pair of the aperture blades into the optical path so as to vary the size of the variable aperture.

摘要： 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.
