Title: Tomoyuki Yamawaki: Innovator in Image Recording Technology
Introduction
Tomoyuki Yamawaki is a notable inventor based in Hyogo, Japan. He has made significant contributions to the field of image recording technology. His innovative work has led to the development of a patented apparatus that enhances the efficiency of image recording processes.
Latest Patents
Yamawaki holds a patent for an "Image recording apparatus with exposure start and toner supply control." This invention includes a photosensitive drum where an electrostatic latent image is formed through laser beam irradiation from an optical unit. The apparatus features a developing unit that receives toner from a feeder and includes a toner agitator. This unit supplies toner onto the drum to convert the latent image into a visible one. A toner sensor detects the concentration of toner within the developing unit, providing a corresponding detection signal. The toner supply controller manages the toner feeder by comparing the sensor's output with a varying standard voltage. Additionally, the exposure start controller initiates the optical unit's irradiation of the photosensitive drum after the drum's rotation stabilizes but before the toner sensor's output reaches its peak level. This innovative design improves the overall performance of image recording devices.
