The Minimum Idea (ミニマムアイデア) is a Japanese strut-folding camera taking 5.5×8cm meishi plates (more precisely 55×82mm). It was made by Rokuoh-sha, manufacturing branch of Konishi (the predecessor of Konica), from about 1911.
The Minimum Idea has a wooden body with an almost rectangular front standard mounted on spring-loaded folding struts inspired from some models of the Folding Pocket Kodak. This front standard contains two brilliant finders, for horizontal and vertical pictures, a simple shutter giving Time and Instant settings, and a simple meniscus lens. The name MINIMUM IDEA CAMERA is inscribed on a small nameplate below the lens.
Commercial life Edit
The Minimum Idea was reportedly released in April 1911. It is listed as a new model (最新型) in the December 1911 catalogue of Konishi Honten, where it is called the "Idea" Minimum Camera (ミニマム、アイデヤ、カメラ). The exposure format is given in older units as 1 sun 8 bu (一寸八分) width and 2 sun 7 bu (二寸七分) height; this translates as 5.5×8.2cm, commonly rounded as 5.5×8cm, and corresponds to the meishi (名刺) format. The dimensions of the camera are given as 9.7×7.3×2.7cm, and its weight as 225g. The camera was supplied with six single-sided plate holders; set A (A號) included a cloth wallet and cost ¥9.50; set B (B號) included a leather case and cost ¥10.50. Various accessories were also offered for the Minimum Idea, including a tripod and various darkroom accessories to process meishi plates.
It is said that the Minimum Idea was a sales success, at least in relation to the state of the Japanese market at the time. In March 1913, Konishi Honten organized photography awards for pictures taken by the Minimum Idea; the selected photographs were displayed at the fourth exhibition of the Tokyo Photographic Research Society (東京写真研究会). A specific photographic club for the owners of the camera, called the Minimum Photographic Society (ミニマム写真会, Minimamu Shashin Kai), was founded on September 20, 1913. It was perhaps the first time that such clubs appeared in Japan around a specific camera; this would later become a common practice, notably around the Vest Pocket Kodak and Pearlette. The Minimum Idea was succeeded by the Korok, and it announced the wide success of the Pearlette.
In the original drawings known so far, the camera has a small leg retracting on the right side of the front standard, allowing it to stand on a table, and has no leather handle. On the surviving examples, minor variations are visible in the shape of the standing leg and of the lock for the plate holders. At least one surviving example has no standing leg at all and has an additional leather handle on the top. It probably corresponds to a later evolution of the camera.
