Title: The Innovative Contributions of Shigeki Muramatsu

Introduction

Shigeki Muramatsu is a notable inventor based in Kakegawa, Japan. He has made significant contributions to the field of optical systems, holding a total of 13 patents. His work focuses on enhancing image reading technologies, which have applications in various industries.

Latest Patents

One of his latest inventions is the Variable Magnification Reflecting Mirror Apparatus. This innovative reading apparatus allows for stepwise or sequential variable magnification using a relatively small optical system. The apparatus features a first mirror that reflects light from the reading position of an original document and a second mirror that reflects this light multiple times before directing it toward an image-forming lens. Additionally, a mirror angle positioner adjusts the angle of the reflection surface based on the designated reading magnification.

Another significant patent is the Image Reading Apparatus. This device integrates a reduction optical system, including a lens and a mirror, along with a CCD image sensor. The entire unit is housed within a frame and covered with a protective cover member. A lamp is positioned on the cover to illuminate the document, while the reflected light is captured by the CCD image sensor, converting it into electrical information for image reading.

Career Highlights

Shigeki Muramatsu has worked with prominent companies such as NEC Corporation and Sankyo Company, Limited. His experience in these organizations has contributed to his expertise in optical technologies and image processing.

Collaborations
