The Idea Spring (アイデア・スプリング) are Japanese strut-folding cameras with a focal plane shutter, made by Rokuoh-sha, the manufacturing branch of Konishiroku (predecessor of Konica). The name Idea was used on various other products by Rokuoh-sha. The name "Spring" was certainly patterned after the German "Klapp", and was probably first used in Japan on this camera; the words "spring camera" (スプリングカメラ) later became a generic term for a self-erecting folder in that country.

First generation
The first generation models were released in 1926.[1] They were available in three different formats: kabine (12×16.5cm), meishi (5×8.5cm) and atom (4.5×6cm).[2] They are only known from original advertisements, and no surviving example seems to have surfaced so far.[3] The kabine cameras seem to have been strongly influenced by, if not directly copied from the Goerz Anschütz Ango.[4] It is worth noting that the date of the release of the Idea Spring coincides almost to the month with the end of production of the Ango in Germany. [5]
Kabine model

The larger kabine model (12×16.5cm) was a copy of the Goerz Ango, as is blatantly said in original advertisements.[6] It has various shutter controls on the right-hand side, a folding optical finder with no cover flaps and a front standard allowing vertical and horizontal movements, locked by two knobscrews. The lens is mounted on a focusing helical with a focus tab. In an early advertisement, the picture shows a multi-creased bellows, and the shutter is said to give 22 settings from 1/10 to 1/1200, other than T and B.[7] Three lens options are listed: Dynar 210/5.5, Collinear 200/6.3 or Heliar 180/4.5, all of them supplied with three double-sided plate holders and one film pack holder. The dimensions are given as 22×18½×6½cm, and the camera is boasted as weighing no more than 1950g with the Heliar lens.[8] One source says that the kabine model cost ¥295 in 1926 with the Heliar lens.[9]

Advertisements for the Idea Spring and Neat Reflex in Ars Camera December 1926 (left) and in Asahi Camera February 1930 (right). (Image rights) |
In the December 1926 issue of Ars Camera, the kabine model was advertised along with the Neat Reflex SLR; no other Idea Spring model was listed. It is presented as the "latest model" (最新型). The picture shows a single-creased bellows; no other difference is visible from the picture described above. The weight is again made a sales point of the camera. Four lens options are listed, all made by Voigtländer:
- Dynar 18cm f/5.5, ¥290;
- Dynar 21cm f/5.5, ¥320;
- Collinear 18cm f/6.3, ¥310;
- Heliar 18cm f/4.5, ¥330.
The pictured camera has the f/4.5 lens.
A very similar advertisement appears in the February 1930 issue of Asahi Camera.[10] The camera is again presented as the "latest model" (最新型), a mention which is now unfounded. The picture is exactly the same, and the only difference is the list of lens options: Dagor f/6.8, Tessar f/4.5 and Heliar f/4.5. The latter is written in bold characters, perhaps because it was considered the most prestigious. No price is mentioned.
Meishi model
The middle meishi model (5×8.5cm)[11] was somewhat inspired by the Ernemann Klapp, but it seems to have four struts hinged at the middle, the same as on the kabine model, instead of the rigid struts of the Ernemann camera.[12] There are two knobs on the photographer's right, apparently copied from the shutter controls of the Ernemann model. The upper knob presumably winds the mechanism and the lower one presumably sets the slit width; there is probably a third control on the left to set the tension of the main spring. The release button protrudes at the front of the right-hand side plate. One advertisement says that the shutter gives 21 settings up to 1/1000, other than T and B.[13] The lens is mounted on a focusing helical with a large focus tab, and is surrounded by a sort of hood, slightly off-centered towards the bottom. It seems that the folding optical finder was originally uncovered, then received two cover flaps copied on the Ernemann camera.[14] The advertisements say that the camera was made of mahogany; one of them mentions "polished wood" (木製塗), another presents it as a "tropical model" (トロピカル・モデル). One advertisement only mentions the Heliar 120/4.5 lens, and says that the camera was supplied with six single-sided metal plate holders and one pack film holder. The other advertisement lists the following lens options:
- Dynar f/5.5, ¥175;
- Heliar f/4.5, ¥200;
- Heliar f/3.5, ¥220.
Atom model
The smaller atom model (4.5×6cm) is presented as a copy of the Ernemann Miniature Klapp in an original advertisement.[15] No picture is known of this model. According to the same advertisement, the shutter gives eight settings from 1/10 to 1/650, other than T and B, the camera was only available with the Heliar 75/3.5 lens, and was supplied with six single-sided metal plate holders and one pack film holder.
Second generation
The second generation models were released in 1932.[16] They were again available in three formats: kabine (12×16.5cm), tefuda (8×10.5cm) and daimeishi (6.5×9cm).
Kabine model
The kabine (12×16.5cm) model was essentially a continuation of the earlier model. It has a neater side plate with two sets of controls: on top is the winding knob for the focal-plane shutter, which is also used to set the slit width,[17] and two releases at the bottom controlling the tension of the main spring (1-4) as well as a counter indicating the tension strength. There is a table riveted between these two controls, showing the shutter speed resulting from the selected settings, from T, B, 8–1000 speeds[18] The text ROKUOH-SHA TOKYO is engraved at the very top of the side plate. The shutter release is placed at the front of the right-hand side plate, in a slightly recessed position; there is a thread for a cable release placed just below.
The bellows are single-plated, the same as on the Goerz Anschütz Ango. The viewfinder is larger than on the previous model, and has cover flaps on both sides, the same as on the late Ernemann Klapp. The front standard is normally similar to that of the previous model.[19] However at least one example is known with a fixed lens standard, allowing no movements, perhaps the result of a repair.[20] The front standard carries an oval metal sign reading 'IDEA SPRING.'
The camera was reportedly available in 1932 with the Dynar 180/5.5 (¥255), Dynar 210/5.5 (¥275), Dagor 180/6.8 (¥295), Tessar 180/4.5 (¥295) and Heliar 180/4.5 (¥295).[21]
Tefuda model
The tefuda model was a new design, much inspired by the Ernemann models, with four straight folding struts, mounted by pairs on spring-loaded axis. However the shutter controls are similar to that of the kabine model, and the mechanism was probably a downsized version of the latter, inspired by the Ango. (This is the reverse of the previous meishi model, which combined an Ernemann-type shutter with Ango-type struts.) The table of shutter speeds is reportedly the exact same part as on the larger model;[22] the viewfinder is similar and the shutter release is placed the same but is not recessed. The front standard has semi-circular indents on both sides, helping to pull it out, and provides horizontal and vertical movements.
The camera was reportedly available in 1932 with Tessar f/4.5 (¥234) and f/3.5 and Heliar f/4.5 (¥234) and f/3.5 lenses.[23] It seems that an Hexar Ser.1 13.5cm f/4.5 lens was offered after some time.[24]
Daimeishi model
The daimeishi model is a downsized version of the tefuda camera. The cable release thread is placed below the shutter button instead of above. The right-hand side plate is inscribed ROKUOH-SHA at the top and has a small additional lever at the bottom. The lens standard has a different construction, apparently allowing horizontal movements only.[25] The only surviving example observed so far has a thick metal plate screwed to the left of the viewfinder, with a protruding pin, whose purpose is unknown.
The daimeishi model was reportedly available in 1932 with Tessar f/4.5 and f/3.5 and Heliar f/4.5 (¥200) and f/3.5 lenses.[26] It was probably released with an Hexar lens after some time, perhaps with the Hexar Ser.1 10.5cm f/4.5, but this is merely a guess.

Third generation
The third generation models were released in 1933 or 1934.
Kabine model

The kabine (12×16.5cm) model was essentially a continuation of the earlier model. It has a neater side plate with two controls only: the winding knob for the focal-plane shutter, which is also used to set the slit width,[27] and a smaller knob at the bottom controlling the tension of the main spring. There is a table riveted between these two controls, showing the shutter speed resulting from the selected settings, from 1/10 to 1/1000.[28] The shutter release is placed at the front of the right-hand side plate, in a slightly recessed position; there is a thread for a cable release placed just above.
It carries the Hexar Ser.1 18cm f/4.5 lens made by Rokuoh-sha itself, perhaps from 1933 or 1934.[29] The helical for the 18cm lens focuses down to 2 metres. The focal length is repeated on the fixed and rotating parts, perhaps to avoid mismatching the helical and lens during the assembly process. The diaphragm is built in the focusing mount, and has many blades, perhaps 17 or so, giving a near perfect circle.[30]
Military models
The kabine and tefuda models were also supplied to the Japanese military forces as the Handheld Land Camera (手持式地上写真機, temochi-shiki chijō shashinki).[31] They have an identification plate riveted to the top, on the right of the viewfinder, and no other visible difference. This plate reads as follows:
- 手持式地上写真機 ("Handheld Land Camera", the name of the camera);
- カビネ (kabine size) or 手札 (tefuda size), in parentheses;
- 第xxx號 (the serial number);
- 昭和xx年x月 (the Shōwa year and month);[32]
- 株式会社小西六工場 / 六櫻社製造 (Made by Rokuoh-sha, a factory of K.K. Konishiroku).
The plate also has an anchor and another sign stamped on it, perhaps indicating that delivery was taken by the Navy. (However a few sources say that the camera was made for the Japanese Army.)[33]
The kabine cameras normally have a Hexar Ser.1 18cm f/4.5 lens[34] , but the example pictured in Sugiyama has a non original Dagor 180/6.8,[35] perhaps taken from a civilian Idea Spring. The tefuda camera has a Hexar Ser.1 13.5cm f/4.5 lens.[36] The serial numbers known so far range from 56 to 1053 [37] The 1939 to 1944 dates inscribed on the military models indicate that they were made long after the introduction of the third generation models in 1933 or 1934. It is not known if civilian production was continued until that time, or if the military models were a resurrection of a discontinued camera. The Idea Spring does not appear in the official list of set prices compiled in October 1940 and published in 1941, thus indicating that civilian sales were stopped at the time.[38]
