Title: Kazuya Hara: Innovator in Optical Reading Technology

Introduction

Kazuya Hara is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of optical reading technology, holding a total of 17 patents. His innovative designs have paved the way for advancements in various electronic devices.

Latest Patents

One of Hara's latest patents is a non-scanning type optical reading apparatus. This apparatus is designed for reading patterns such as bar codes. It features an imaging lens that captures the bar code as a pattern to be read, along with a CCD line sensor that reads the information from the image. Additionally, it includes a light damping mirror and/or filter positioned between the pattern and the CCD line sensor. The central part of the light damping mirror filter is denser than the periphery, ensuring a uniform distribution of light on the sensor. In one embodiment, the filter is a bandpass filter.

Another notable invention is a compact type electronic information card. This intelligent card is designed to have a calculation function and a card holder collation function, matching the size of a credit card. The collation function allows numeral data input from a key input section of the card to be compared with identification data stored in an internal integrated memory circuit. While traditional IC cards can be relatively expensive, Hara's intelligent card offers an economical solution by incorporating a calculation function alongside the IC card capabilities.
