  • Image recording apparatus and application device thereof
    Patent number: 6201594
    Abstract: An image recording apparatus which effects digital exposure while aiming for compactness. An exposure unit digitally exposes a photosensitive material successively while moving above a stage. An application unit moves from the rear side of the exposure unit and applies water successively to the photosensitive material. A superposing unit moves from the rear side of the application unit, and successively superposes an image-receiving material on the photosensitive material. Heat development transfer is carried out, and an image is obtained on the image-receiving material.
    Type: Grant
    Filed: September 8, 1998
