Title: Kenkichi Tagawa: Innovator in Electrophotographic Technology
Introduction
Kenkichi Tagawa is a notable inventor based in Ebina, Japan. He has made significant contributions to the field of electrophotographic technology, particularly in the development of fixing devices for copying machines. With a total of 2 patents, his work has had a lasting impact on the efficiency and quality of photocopying processes.
Latest Patents
One of Tagawa's latest patents is a fixing device for use in electrophotographic copying machines. This invention features a contact fusing apparatus that includes a heated roll structure working in conjunction with a pressure roll structure. This design creates a nip through which support material carrying toner images is moved, ensuring that the toner images come into contact with the heated roll structure. The contact fuser is distinguished by its stripping means, which guarantees the removal of the support material from the heated fuser roll. Additionally, a roller structure is interposed between the stripper means and the nip, which contacts the support material to restrain it while the leading portion is stripped from the heated roll. This innovative approach minimizes the curling of copy paper during the process.
Another significant patent by Tagawa is a fixing device in an electrophotographic copying machine. This device includes stripping members that are in contact with the surface of a heating roll, along with conveying rolls that serve to transport the support material while it is held between them. These components are strategically positioned on the feedout side of the heating roll to thermally fix a thermoplastic material on the image support material. Notably, the peripheral speeds of the conveying rolls are higher than that of the heating roll, enhancing the overall efficiency of the fixing process.
