Yamagata
Yamagata Kikai Kōgyō K.K. (山形機械工業㈱) was a Japanese company founded in December 1946, that was dependent of Tōkyō Kōgaku and was based in the town of Yamagata (山形).[1] It made the Semi Oscon 4.5×6 folder, distributed by Ōsawa Shōkai in 1953 and 1954, with lenses provided by Tōkyō Kōgaku. It became K.K. Topcon Yamagata (㈱トプコン山形) in 1971 and still (2007) exists under that name.[2]
Notes
- ↑ See the chronology of the Topcon official website and the chronology of the Topcon Yamagata official website. Lewis, p. 79, says that it was affiliated with Nippon Kōgaku, certainly by mistake.
- ↑ See the chronology of the Topcon Yamagata official website. Lewis, p. 79, says that it "went out of business", certainly by mistake too.
