Latest Patents

Two of Hirota’s listed patents focus on cleaning mechanisms for image-forming equipment.

“Image Forming Apparatus with Variable Efficiency Cleaning Mechanism” describes a system that adjusts cleaning efficiency according to image-forming conditions. In one embodiment, the apparatus changes the contact pressure between a cleaning blade and an image carrier. This approach is intended to reduce wear on both components. For color apparatus, the relevant conditions may depend on whether the image is monochrome, composite color, or simul-color.

“Cleaning Device” concerns removing residual toner from a toner image carrier. A blade contacts the carrier at an acute angle and scrapes away toner, while a collecting device moves in the opposite direction to gather the removed material.

Career Highlights

Hirota’s listed inventions address practical challenges in image formation, including residual-toner removal and the wear that can result from cleaning. His patent work reflects an emphasis on cleaning-device design and the operation of image-forming apparatus.

Collaborations

Hirota’s listed coworkers include Futoshi Okazaki and Hiroshi Sakakibara. His work is associated with Minolta Company, Ltd.

Conclusion

Shingo Hirota’s patent portfolio highlights engineering approaches to cleaning image carriers, managing residual toner, and reducing component wear in image-forming equipment.
