Latest Patents

Isonaka holds a patent for an "Identification card producing apparatus." This apparatus is designed to create identification cards that include a photograph of a person along with written material. The process involves using a photoreceptor with a layer of photoconductive material that is charged and exposed to an optical image. This exposure forms an electrostatic latent image of the person on the photoconductive material layer. The identification card material, which has a layer of dielectric material, is then placed on top of the photoreceptor to transfer print the electrostatic latent image. Finally, toner particles are supplied to develop the image into a visible format, and written matter can be added before the card is laminated for protection.
