Title: Keizo Nishiguchi: Innovator in Image Processing Technology
Introduction
Keizo Nishiguchi is a notable inventor hailing from Osaka, Japan, with a commendable portfolio of six patents to his name. His inventions have largely contributed to advancements in image processing technology, specifically in the realm of sheet-like media processing and laser beam printing.
Latest Patents
Nishiguchi's recent innovations include a "Processing Device for Sheet-like Media." This device processes sheets by immersing them in a special fluid, allowing for the effective removal of printed materials, such as toner, from copy sheets. The device features a tank that holds the fluid, along with mechanisms for feeding sheets into the tank, accommodating sheets, and sensing the state of the sheets. Notably, this design simplifies the removal of jammed sheets without requiring the operator to directly handle the fluid.
Another significant patent of his is the "Laser Beam Printer Capable of Forming Line Images Having Stable Image." This advanced image forming apparatus allows electrostatic latent images to be developed on the surface of a photosensitive member. A reference line image is formed outside the effective image forming area, enabling the changing of the developing bias voltage based on sensor detection of the line image width, which helps maintain image quality.
