Idea No.1
The Idea No.1 (アイデア一号) are Japanese plate folders made by Rokuoh-sha, the manufacturing branch of Konishiroku (predecessor of Konica). They exist in meishi (5.5×8cm), daimeishi (6.5×9cm) and tefuda (8×10.5cm) size, and replaced the Idea A and Idea B series in 1923. The Pearl No.2 released the same year is essentially a rollfilm version of this camera line.

Description
The Idea No.1 models have a mixed construction, with a wooden main body and a metal folding bed.[1] The folding struts are quite large, and there is a handle at the top of the main body. The front standard mainly consists of a U-shaped metal part, and has no visible movement ability. The brilliant finder is attached to the top of the lensboard, straight in the middle. The bellows have single extension, and there is a distance scale on the photographer's left.[2] The name N°1 IDEA is sometimes inscribed at the bottom of the front standard; at least some examples also have an IDEA embossing in the top handle, and an Idea logo on the ground glass hood.
The larger tefuda (8×10.5cm) model has a focusing wheel on the photographer's right, and a rigid brilliant finder covered by a hood.
The smaller meishi (5.5×8cm), then daimeishi (6.5×9cm) model, has no focusing wheel but a lever in front of the lens standard, whose exact purpose is unknown. The brilliant finder is collapsible and has a square window.

Commercial life

Some sources claim that the Idea No.1 was released in August 1923, others say that it appeared in 1924.[3]
The November 1924 advertisement in Ars Camera shows an illustration of the smaller model. The camera is said to take film plates or pack film, and the format is not mentioned. Nothing is said of the shutter, and three lens options are listed:
The meishi and tefuda models were also offered in 1924 with Testar lenses; Tanaka suggests that this temporary measure was taken because the company was facing a shortage of lenses after its stocks were destroyed in the 1923 Great Kantō earthquake.[4]

The advertisements in Ars Camera June 1926, December 1926 and February 1927 shows the same illustration as in November 1924. In June 1926, the cameras are said to have received the medal of honor (名誉賞牌) at the Second Chemical Industrial Exposition (第二回化学工業博覧会),[5] and prices are given for the versions with f/6.8 lens: ¥35 in meishi size and ¥45 in tefuda size, with a mention of "other models" (外種々). The December 1926 advertisement gives no specific information on the Idea No.1, and the February 1927 advertisement offers the camera from ¥29 in meishi size and from ¥45 in tefuda size.
In the May 1927 advertisement in Ars Camera, important changes are announced for the Idea No.1 and Pearl No.2. The film size of the Idea No.1 is switched to 6.5×9cm, and an insert taking regular meishi-size plates is supplied as an accessory.[6] The price is given as ¥35 with a Deltas f/6.8 lens, six single-sided metal plate holders and one film pack holder. Another advertisement dated 1927 and mentioning the format change also lists a version with Trinar f/6.3 lens for ¥40.[7]
