Shinkō Seiki (perhaps 新光精機) was a Japanese camera maker in the early 1940s. The company is mentioned as "Shinkō" (新光) in the April 1943 government inquiry on Japanese camera production. Its full name Shinkō Seiki is only known from a marking on a Rorox camera. The company made the Shinko Baby and certainly the Shinkoflex and Shinko Super, as well as the Shinko enlarger; all these products were distributed by Yamashita Shōten, of which Shinkō was perhaps a dependent company. It also made the Baby Doris distributed by Fukada Shōkai, and the Rorox, perhaps a name variant of the Shinko Baby.
