Title: Innovations by Katsutoshi Seguchi

Introduction

Katsutoshi Seguchi is a notable inventor based in Aichi-ken, Japan. He has made significant contributions to the field of optical devices, particularly in the context of facsimile machines and image scanning technologies. With a total of 2 patents, his work has enhanced the efficiency and accuracy of document processing systems.

Latest Patents

One of Seguchi's latest patents is a light illumination assembly featuring a tapered light guide plate. This optical guide device is designed for use in facsimile devices, copying machines, and image scanners. The assembly includes an array of LEDs and a light guide plate that, when cut along the longitudinal axis, reveals a tapered cross-section. This design allows for an increase in thickness at the side facing the light array, resulting in high and uniform light intensity. Consequently, a CCD unit can accurately capture the light reflected from documents.

Another significant patent by Seguchi involves a light reflection type detection device in facsimile machines. This device includes a reflection type sensor mounted directly on a control board. An actuator, which is pivotally supported in the main frame of the facsimile machine, has arms that interact with the sheet medium. As the sheet medium is transferred, it triggers the actuator, allowing the reflection member to align with the reflection type sensor, thus detecting the passage of the sheet medium.
