The Ricoh Six is a Japanese 6×6 folder. It was made from 1952, by Riken's subsidiary Asahi Seimitsu, which was in charge of camera development at the time, before it was merged in 1953 into its parent company Riken Kōgaku Kōgyō.
The Ricoh Six is a horizontal folding camera. The folding struts are inspired by the Ikonta. The top plate has a chrome finish, with the tubular optical finder in the middle. The advance knob, placed at the left end, has two arrows to indicate the winding direction and a round piece of leather. On the left of the finder, there is an accessory shoe and a button to release the folding bed. There is a body release and a leather-covered film retaining flange at the right end of the top plate. The name RICOH SIX and the serial number are engraved to the right of the finder. The name is repeated on the leatherette covering of the front door.
The camera can take 6×6 or 4.5×6 pictures with an exposure mask. The back is hinged to the right and contains two red windows placed in the middle, one above the other. They are protected by sliding covers, engraved 4.5X6 and 6X6. Indications of the format (6×6 or 4.5×6) are also embossed in the leatherette covering, under the levers controlling the red window covers.
The lens is a three-element C. Orinar Anastigmat 80mm f/3.5. The shutter gives B, 25, 50, 100 speeds and is engraved RIKEN at the bottom of the speed rim. It is synchronized via an ASA bayonet post and has a distant release connection.

All the examples observed so far are identical. The known serial numbers have four digits in the 1xxx and 2xxx range (lowest is 1118, highest is 2953), in a sequence probably starting at 1001. The numbers on the Orinar lenses are more or less in the same range (lowest is 1185, highest is 3731). The total production was probably around 2,000 or 3,000 units.
- ↑ Kokusan kamera no rekishi, p.372, mentions a May 1952 article about the camera. The release year is given as 1952 in Sugiyama, item 1413, and in McKeown, p.831. It is given as 1953 by mistake in "Rikō 6", p.45 of Kurashikku Kamera Senka no.14, and in this page of the Ricoh website.
