Revision as of 19:36, 5 April 2009
The Gokoku (ゴコク) and Ricohl (リコール) are Japanese cameras taking 3×4cm pictures on 127 film, made by Riken Kōgaku Kōgyō (the predecessor of Ricoh) and originally announced in 1938 as the Riken No.1. They have a focal plane shutter and look like the Leica screw models, without a rangefinder. (It is said that the Roico 4×4cm camera with leaf shutter used the body of the Gokoku and Ricohl in a slightly modified form.)[1]
Contents
Context and possible predecessors
The Gokoku was preceded by the Lausar and Baika with the same features, made c.1937 in small quantities by Tomioka and perhaps Sankyō Kōgaku. The general aspect and the layout of the controls are very similar to the Riken No.1 and Gokoku but the body is more angular and it seems that no part is shared with Riken's models. The striking design similarity nonetheless leads to the hypothesis that Riken took over the Lausar or Baika project from Tomioka or Sankyō and developed it into the Gokoku.
These Japanese models were not the only 3×4cm cameras with a focal plane shutter: other examples are the Foth Derby, the Ensign Multex or the French Lumière Elax, Gallus Derlux and Pontiac Lynx II. However they were perhaps the only ones with an exposure counter and film advance fully coupled to the shutter winding.
The Riken No.1
The Gokoku itself was first announced by Riken Kōgaku Kōgyō as the Riken No.1 (理研NO.1) or Riken Camera (理研カメラ) in advertisements and articles dated October 1938.[2] The pictured camera is identical to the Gokoku but it seems to have no markings above the top plate. The shutter speed range goes from 1/20 to 1/500.[3] The lens looks like it is interchangeable but this is not mentioned anywhere in the original documents.[4] It has a large focusing tab, different from the part normally found on the Gokoku lenses. The lens was said to be a Ukas Anastigmat f/3.5 in the October 1938 Asahi Camera article but it was announced as a Riken Kōgaku Anastigmat f/3.5 in the advertisements and the pictures show the engraving RIKEN 1:3.5 F=50mm.
The Riken No.1 was available for ¥195 to subscribers only (the same price as the Weha Chrome Six and Auto Semi Minolta).[5] It seems that the camera was never produced under that name and no surviving example has surfaced so far. It is said that the delivery was delayed and that this caused complaints.[6]
The Gokoku
The Riken No.1 was actually sold in 1939 and 1940 under the name Gokoku (or Gokoku No.1). The word gokoku (written 護国) means "protector of the country", it is an example of the "patriotic" wartime names often used by Riken.
Description
The camera has a metal body with leather covering and chrome-plated top and bottom plates. The viewfinder is offset to the left, as seen by the photographer, and is contained in a casing extending to the right. The name GOKOKU N°1 is engraved above the finder (with a stylized G) together with the R.K.K initials of Riken Kōgaku Kōgyō. The accessory shoe, speed dial and shutter release are above the top casing, to the right of the viewfinder. The speed dial has Z, 20, 30, 40, 60, 100, 200, 500 settings. The serial number is engraved in front of the accessory shoe.
The advance knob is at the right end, it turns in the counter-clockwise direction and is surrounded by the exposure counter. The film is advanced and the shutter is wound in the same movement.[7] Because of the absence of perforations, the film advance mechanism only relies on feeler-rollers, and was plagued with reliability problems.[8] There is a fake rewind knob at the left end of the top plate: the camera does not need rewind and it is only there to mimic the Leica.
The back is removable together with the bottom plate for film loading. It is locked by keys at both ends, and the bottom plate also has a tripod thread. There is a single red window at the left end of the back, used to set the position of the first exposure. It is protected by a cover that is retracted by a thumbwheel surrounding the red window.
Original documents
In an advertisement dated February 1939 by Riken Kōgaku Kōgyō, the Gokoku was listed among the camera range for ¥195 (the name was written 護国).[9] A full advertisement for the Gokoku was inserted in the October 1939 issue of Shinkō Graph. The camera was presented with a fixed Gokoku Anastigmat f/3.5 lens and the price was ¥170.[10] The Gokoku was listed again in another advertisement dated October 1940 in Asahi Camera.[11] It was also listed for ¥190 in the list of set prices compiled on October 1940 and published in January 1941.[12]
Variations
With fixed lens
The regular version of the Gokoku has a Gokoku Anastigmat 50mm f/3.5 fixed lens, with a collapsible barrel. The focusing helix is driven by a tab, and the lens focuses down to 0.5 metre. The front rim is engraved GOKOKU ANASTIGMAT 1:3.5 F=50mm and the lens number is engraved on the distance scale. The diaphragm is controlled by an index around the front element. On some lenses, the aperture scale is 3.5, 4.5, 6.3, 9, 12.5, 18; on others it is 3.5, 4.5, 5.6, 8, 11, 16, 22. The camera normally comes with a metal lens cap engraved RKK.
Variations are known in the feeler roller system advance system, presumably because of an attempt of making the troublesome mechanism more reliable. Some cameras have a roller attached to the back and facing the main roller inside the body. On others, there is a metal bridge forcing the film onto the main roller and the pressure plate is accordingly modified.[13]
Examples have been observed with body numbers ranging from 1168 to 2954 and lens numbers ranging from 10168 to 12043. The production of this version can be estimated at about 1,500 to 2,000 units.
With interchangeable lens
One example of the Gokoku is known with an interchangeable lens; it has body no.1887 and comes with an Ofunar 50mm f/3.5 lens (no.48010).[14] It is not known if a small batch of interchangeable-lens cameras were made, or if that particular example is an isolated prototype or an aftermarket conversion. The lens mount is the standard Leica thread mount; it is said that the camera can take regular Leica lenses but that they end up in the upside down position, with the infinity setting at the bottom.[15]
The Ofunar 50mm f/3.5 lens found with the camera is the only example of its kind observed so far. The collapsible barrel is closely copied on the Leitz Elmar 5cm f/3.5. The focusing mount is driven by a tab with an infinity lock, and goes down to 1 metre. The front rim is engraved Ofunar 1:3.5 f=50mm N°xxxxx. The diaphragm is controlled by an index around the front element, and the aperture scale goes from 3.5 to 18. It seems that the lens has a rangefinder coupling cam;[16] this is useless on the Gokoku, and it is not known for sure if it is properly adjusted for Leica-mount rangefinder cameras.

Little is known on that Ofunar lens. It is not certain that it was originally mounted on the camera, but the inverted mount makes this quite plausible. The Ofunar brand was used after World War II by the company Ōfuna Kōgaku, which started during the war as a factory of Tomioka in Ōfuna, near the city of Kamakura. The lens might have been manufactured in that factory, either during the war by Tomioka for Riken, or after the war by Ōfuna to fit a specially converted Gokoku — the serial number 48010 might indicate year 1948 and come in favour of that theory. The lens looks very similar to the Lausar 5cm f/3.5 made by Tomioka for the Lausar camera (see above), but the similarity between these two Elmar copies might be fortuitous.
Accessory rangefinder
An external rangefinder was available for the camera. It is marked RKK and GOKOKU RANGE-FINDER, and it was copied on the external rangefinder of the Leica Standard, with a shorter base.
The Ricohl

Riken launched the Ricohl, successor of the Gokoku, around late 1940. It is said that Ichimura Kiyoshi (the founder of Riken Kōgaku Kōgyō) sought the help of Fujimoto Sakae (藤本栄), who would later design the Ricohflex III, to make the camera more reliable.[17]
Description
(Image rights) |
The Ricohl has a longer top housing covering the whole top plate. The finder is larger and the fake rewind knob has been suppressed. The accessory shoe, speed dial and release button are similar to the parts mounted on the Gokoku. The advance knob is different, it turns in the clockwise direction and contains the exposure counter. There is an index next to the advance knob, pointing to the frame number. The advance mechanism was completely reworked, and the knob is now turned clockwise. It is said that the shutter is wound first and the film is advanced next, and that this needs about three turns of the knob.[18] The auto-stop mechanism still relies on feeler rollers, but now works reasonably well.[19]
The name Ricohl is engraved above the viewfinder, together with the model number and the initials R.K.K for Riken Kōgaku Kōgyō. The serial number is engraved in front of the accessory shoe.

The Ricohl I
The Ricohl I (リコールⅠ型) has the same fixed-mount Gokoku Anastigmat 50mm f/3.5 lens as the Gokoku. The aperture scale usually goes from 3.5 to 18, but at least one advertising picture shows f/22 minimum aperture.[20]
The Ricohl (I) already appears in the list of set prices compiled in October 1940 and published in January 1941, at ¥190.[21] Advertisements showing the same price of ¥190 appear in the February, March and October 1941 issues of Shashin Bunka.[22] The camera was also featured in the new products column of the April 1941 issue of Asahi Camera.[23]
Examples of the Ricohl I have been observed with body numbers ranging from 2750 to 4143 and lens numbers ranging from 10642 to 12285. It seems that the serial number sequence continues the sequence of the Gokoku, with some overlap at the beginning of the production, and that about 1,000 to 1,500 examples of the Ricohl I were produced.
The Z indication on the speed dial was substituted by B soon after the beginning of the production run.[24] A few examples are known with maroon leather covering, which is perhaps original.[25]

The Ricohl II
The Ricohl II (リコールⅡ型) is a more expensive version, about which little is known. It was briefly announced but no picture has been found yet, and no surviving example has ever surfaced.
The Ricohl II already appears in the list of set prices published in January 1941, at ¥335 with no further detail.[26] The price was set according to the camera characteristics, and is on par with the original Leotax and with the rangefinder versions of the Canon, perhaps indicating that it was equipped with a rangefinder too. The camera was also advertised for ¥314 in 1942, along with the Ricohl IIB at ¥256.[27]
The Ricohl IIB
The Ricohl IIB (リコールⅡB型) has an interchangeable lens using a specific screw mount, with 40mm diameter, 32 threads per inch and 27.9mm flange to film distance.[28] Very few examples have been observed so far, and the only observed serial number is in the 44xx range.[29]
The Ricohl IIB was offered for ¥256 in various advertisements dated February 1942.[30] The price later rose to ¥291.48,[31] and the camera was advertised until mid 1943.[32] The Ricohl is still mentioned in a government inquiry listing the Japanese camera production as of April 1943, with no specification of a model name.[33] In that document, the focal plane shutter is said to give B, 1–500 speeds, surely by mistake.[34]
Neutar 50mm f/3.5 lens
The standard lens of the Ricohl IIB is a collapsible four-element[35] Neutar 50mm f/3.5, seemingly made by Riken itself.[36] It is probable that no other lens was made for the camera. The diaphragm is controlled by a ring around the front element, and the aperture scale goes from 3.5 to 18. The front rim is engraved NEUTAR 1:3.5 F=50mm, sometimes with two dots around the NEUTAR name.[37] No lens number is visible. Variations are known in the size and shape of the focusing tab: it is either small with a striated tip, or large with a smooth tip (reminiscent of the focusing tab visible on the pictures of the Riken No.1).[38]
One isolated example of the Neutar 50mm f/3.5 lens is known in genuine Leica screw mount.[39] It is equipped with an oblique coupling cam at the rear, made to fit a rangefinder camera, perhaps the hypothetical Ricohl II. It differs from the above lenses by the slightly larger fairing for the focusing helix, and by an infinity lock replacing the stopping screw. It has the small focus tab and the two dots around the NEUTAR name.
