Latest Patents

Hiraga's latest patents demonstrate his ingenuity in the realm of image reproduction. The first, titled "Color Image Reproduction Apparatus," details a machine capable of producing vibrant polychromatic reproductions of color originals. This apparatus employs a light scanner to capture the color original, which is then separated into red, green, and blue light images using a prism or color filters. A memory component is included to store these color-separated images. The design incorporates multiple marking units positioned around a transfer drum, which facilitates the formation of cyan, magenta, and yellow toner images that can be transferred onto copy paper with perfect registration. The precision of this system is enhanced by a controller that synchronizes the operation of each marking unit to the movement of the paper.

The second patent, "Copying Device with Facsimile Function," reveals a sophisticated copy machine featuring a plane stationary platen and the capability of facsimile transmission and reception. In this innovation, a first scanning mirror operates in parallel with the platen at the same speed as the photosensitive medium, while a second scanning mirror is synchronized to move at half that speed. The technology employs an in-mirror lens system combined with a beam deflector, facilitating the selection of optical paths for directing laser beams toward either the platen surface or the photosensitive medium, enhancing both copying and transmission functionalities.
