The Riken Roico was a 4x4cm format camera released in 1940. It is said on this page from the All Japan Classic Camera Club that the Roico was made by Riken Optical Industries (Riken Kōgaku Kōgyō, 理研光学工業) whereas the Riken Letix introduced the same year was made by Asahi Optical Industries (Asahi Kōgaku Kōgyō, 旭光学工業), a sub-company of Riken.
The Roico had a metal body, and the back was removed together with the bottom plate. The lens and shutter assembly was mounted on a telescopic tube. It had a body release, a tubular optical finder, an accessory shoe and a frame counter, similar to the Adler IV. The frame counter was necessary because at the time, the film paperback was not marked for 4x4cm pictures. The lens was a Roico Anastigmat 60/3.5 triplet. There were two variants depending on the shutter:
- the early Roico, from 1940, with a T-B-5-200 shutter (see here) or T-B-5-250 shutter (see here), Ricoh's corporate site says T-B-25-50-100-150 everset, contradicted by the picture
- the later Roico, from 1943, with a NKS Tokio T-B-1-200 shutter (Tokio is maybe an old transcription of Tokyo)
Ricoh's corporate site says that the Roico was based on the focal plane shutter Gokoku / Ricohl model, adapted for a simpler lens shutter. It also says that Roico was the acronym of Riken Optical Industry Co.
