  • Patent number: 6625395
    Abstract: In a digital instant camera, a fixed exposure head emits a printing light to an instant film contained in a film pack, and a spreading roller performs a developing process. While the instant film is conveyed by the spreading roller toward the outside of the camera, the exposure head emits the printing light in synchronism with the conveyance of the instant film. A conveyance speed of the instant film is suddenly increased at the moment that a developer pod provided on the instant film is broken by the spreading roller. A brake roller, however, prevents the conveyance speed from suddenly increasing. In virtue of the brake roller, the printing light may be surely emitted to the instant film.

  • Patent number: 6499893
    Abstract: An image-recording device that improves processing speed for image-recording that is carried out using a light and heat sensitive recording material. At the same time as irradiation of the light and heat sensitive recording material with light by a light source for fixing, a heating device heats the light and heat sensitive recording material. Because photo-fixing/photo-decolorization is carried out while the light and heat sensitive recording material is heated, viscosity of the system decreases, and dispersibility of active radicals increases. Due to this activation of radicals, a photopolymerization reaction and a photo-decolorization reaction accelerate, so that efficiencies of fixing and decolorizing increase.
