【Hitachi 】 H-8252 Optical Character Reader

The Hitachi H-8252 optical character reader was a document reader that could read characters and marks on relatively small forms. The reader was designed primarily to address the need to read turnaround forms. The H-8252 was the first domestically produced general-purpose OCR reader that supported general applications. Document readers were first used in Japan in 1965, and Hitachi entered the market with a U.S.-made OEM product (the H-5820). By producing the H-8252 domestically, Hitachi was able to outfit it with many outstanding features, including processing speeds, reading performance, mechanical assembly stability, and the ease of recovering from an unreadable character. The primary application was reading handwritten marks to meet the need of the life insurance industry to process monthly insurance premiums and the need of power and gas utilities to process meter-reading cards.
