The Ricoh Six is a Japanese 6×6 folder. It was made around 1952–3, perhaps by Asahi Seimitsu Kiki Kōgyō, a depending company of Riken, or by Riken Kōgaku Kōgyō, into which Asahi Seimitsu was soon merged.^[1]

Description

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. The name RICOH SIX and the serial number are engraved on the top plate, to the right of the finder. There is a body release and a leather-covered film retaining flange at the right end.

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.

The lens is a three-element C. Orinar Anastigmat 80mm f/3.5.^[2] 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.

Production

The Ricoh Six was featured in a column of the May 1952 issue of Asahi Camera.^[3] This article reportedly mentions a Ricoh 80/3.5 lens, but this lens name has not been observed so far.^[4]

At least one source says that the Ricoh Six was made by Asahi Seimitsu Kiki Kōgyō (旭精密機器工業), a depending company of Riken, that was finally merged into Riken Kōgaku Kōgyō in 1953.^[5] It is also said that the body was bought from a sub-contractor.^[6] The lens was made by Fujita Kōgaku^[7] and the Riken shutter was the same as mounted on the Ricohflex III, IV, VI and VII.

The Ricoh Six was mainly sold in the PX shops of the occupying American army in Japan.^[8] It is said that it cost ¥6,800.^[9] It seems more common in the USA than in Japan.

All the Orinar lenses observed have a four-digit serial number (lowest is 1654, highest is 3731). The body numbers are more or less in the same range (lowest is 1696, highest is 2953). The total production was probably around 2,000 units.

Notes

1. ↑ Date: "Rikō 6", p.45 of Kurashikku Kamera Senka no.14, and this page of the Ricoh website say 1953, but Kokusan kamera no rekishi, p.372, mentions a May 1952 article about the camera, and Sugiyama, item 1413, and McKeown, p.831, say 1952.
