Title: Syoji Sagae: Innovator in Electrophotographic Technology
Introduction
Syoji Sagae is a notable inventor based in Hitachiota, Japan. He has made significant contributions to the field of electrophotographic technology, holding a total of 9 patents. His work has advanced the capabilities of color image printing, making it more efficient and effective.
Latest Patents
One of Sagae's latest patents is a color image electrophotographic apparatus designed for printing long-size copies. This innovative apparatus utilizes multiple development units to form color toner images on a photo-sensitive drum. The exposure and development processes are executed repeatedly for each hue of the image information. The toner images of various colors are transferred to the drum by making contact with the recording paper. The apparatus is capable of selecting a record mode based on the length of the image information in relation to the drum's peripheral length. If the image information exceeds the drum's length, multiple transfer processes are employed, dividing the image into several areas for effective recording. Conversely, if the image is shorter, a single transfer process is utilized.
Another significant patent involves an image transfer apparatus that employs a roller to create a curve in the recording paper. This design allows for the toner image, formed on the curved surface of a photosensitive drum, to be transferred effectively along the curved surface of a transfer drum. The roller is strategically placed in the path of the recording paper to ensure optimal contact with the transfer drum.
