The Ricohflex B (理光フレックスB型) is a Japanese 6×6 TLR made and sold by Riken Kōgaku Kōgyō in 1941 and 1942.[1]

Description

The Ricohflex B is a 6×6 TLR made of pressed steel.[2] It is a close copy of the early versions of the Richter Reflecta with three red windows.[3] The focusing is done by a lever at the bottom of the taking lens, driving a helicoid supporting the lens and shutter assembly. The viewing lens is coupled to the helical focusing, certainly by internal coupling gears.

The film advance knob is on the photographer's right. The back is hinged to the top and contains three red windows on the left, protected by a vertically sliding cover. Indications are embossed in the back leather next to the red windows: 1357, 2468 and 1357, meant to use the 1 to 12 series of numbers for the 6×9 format. The exposure chamber and film spool holders are grouped in a removable frame.

There is a depth-of-field plate written in English on the back of the viewing hood, and strap attachments on both sides of the body. The nameplate is inscribed Ricohflex and MOD.B. Two variants of the nameplate are known, one is almost rectangular and has MOD.B written in small capital letters, the other has an incurved top and MOD.B written in larger letters.

The shutter gives T, B, 5–200 speeds on all the versions. On the early examples, the shutter is everset and the shutter plate is inscribed HEIL at the top and has an AKK logo on the right. On the late examples, the shutter has a setting lever and no shutter name is visible.[4]

The viewing lens is a Ukas Anastigmat 75mm f/4.5. The taking lens is the same Ukas Anastigmat on the early examples and it is a Koa Anastigmat 75/4.5 on the late ones.[5]
