摘要: An image recording apparatus having an exposure unit, a pressure developing unit and a thermal fixing unit. The apparatus employs a separate type image recording mediums including a microcapsule sheet and a separate developer sheet. The thermal fixing unit applies heat to the developer sheet carrying an output image thereon. A heat application means of the thermal fixing unit is positioned spaced away from the imaging surface of the developer sheet for avoding direct contact therewith.

摘要: A sheet heating device having heat insulators for preventing at least one of sheet feeding roller and sheet discharge roller from being overheated. The sheet heating device includes a delivery unit for delivering a piece of sheet, a heating unit for heating the sheet on a delivery path of the sheet, a cover member for covering the heating unit and opening on a feed side and a discharge side of the sheet, respectively, and two pairs of rollers adapted to close respective openings of the cover member. The pair of rollers serve as heat insulators for avoiding overheating to the sheet feeding and discharging rollers. Shutter members are also available for heat insulation. The shutter members also serve to confine hot air within an interior of the heating device.

摘要: A method and an apparatus of exposing a photosensitive medium for forming thereon a latent image which corresponds to an original image to be reproduced and which is developed into a visible image. The photosensitive medium has a basic minimum amount of exposure to a radiation, below which a density of the visible image remains constant and above which the density varies with an amount of exposure to the radiation. An entire recording surface of the photosensitive medium is evenly exposed to a first radiation by a predetermined first exposure amount determined by the basic minimum amount, and each label area of the recording surface is exposed to a second radiation by a second exposure amount which corresponds to a density in a corresponding local area of the original image, so that the first and second exposure amounts cooperate to form the latent image.
