Introduction

Tohru Uchida is a notable inventor based in Hachioji, Japan. He has made significant contributions to the field of recording apparatus technology, holding a total of 6 patents. His work primarily focuses on improving the efficiency and functionality of paper feeding devices and toner collection systems.

Latest Patents

One of Uchida's latest inventions is a paper feeding device for recording apparatus. This device is designed to feed stacked paper to an electrophotographic copying machine. It features a lift for the stack of papers, which moves the top sheet against a swingably supported feeding roller as the stack size decreases during use. Additionally, a plate in frictional contact with the roller helps to feed the paper forward to the copying machine, effectively preventing multifeeding issues. The feeding operation is enhanced by separating claws that engage the leading corners of the paper as it passes from the feeding roller.

Another significant patent is for a collecting apparatus for scattering toner. This apparatus includes an air flow path and a toner collecting chamber at one end. A suction device generates a directional flow of air to transport scattering toner through the air flow path to the collecting chamber. Magnets within the chamber facilitate toner collection, and a filter made of magnetizable material can enhance the collection capacity and efficiency.
