Takane Kōgaku (高嶺光学, Takane Optical), was from 1953 to 1958 the maker of several folding roll-film cameras, most models of which had an integrated range/viewfinder and unit focusing and were sold as the Mine Six. The final model, the Super 66, was remarkable as the first Japanese folder to have a coupled exposure meter.

The manufacturer that became Takane was started by Mr Izawa (井沢広治) in 1952, in suburban Takasaki (north from Tokyo), and more precisely in the garden of his father, a farmer. (The resulting company would remain in the Takasaki area until its demise.) Izawa's factory produced components for other companies, among which was Mihama Seikō (三浜精工; very soon to be Suruga Seiki, 駿河精機), for whose Mihama Six it produced the body.

In 1953, Izawa determined to make his own camera. He obtained a loan from Daidō bank (now the Gunma Bank), created a company that he gratefully named Daidō Seikō (大同精工, Daidō precision engineering) and, using the body first designed for the Mihama Six, he produced two folding viewfinder cameras, the Daido Six and Semi.

A change of company name to Takane Kōgaku soon followed, with a new camera, the Sisley 55, which added a (non-coupled) rangefinder to the Daido Six.

The Sisley 55 was a solid camera, but not a remarkable one. Izawa realized that he needed a better product, which in turn would require specialist knowhow. He employed a new head of production, Machida Nobuyoshi (町田信義), and also had the good fortune to attract the attention of a well-heeled elderly enthusiast, the aristocratic local photographer Sakurai Ihei (桜井伊兵衛), who in turn encouraged Izawa to employ as designer Takamatsu Kingo (高松金吾), who had worked at Konishiroku during the war and was now a teacher of engineering in Takasaki and whose handmade TLR had impressed Sakurai. Takamatsu designed the first Mine Six, whose most obvious innovation was unit focussing (i.e. focussing by movement of the entire lens assembly, and not merely the frontmost element), but which also had an improved shutter and an S-Kominar lens from Nittō Kōgaku (日東光学), whose president, Kaneko Sadamasa (金子定正), took a great interest in the camera and gave useful advice for collimation and other adjustments.

The next model, the Mine Six IIF, had a coupled rangefinder, but Takane still wanted improvements to keep their product competitive, so an improved version of the IIF was released with a Copal shutter and Asahi Takumar lens.

The next stage was the IIISB (or IIIS), which had two advances. First, "semi-automation": film advance stopped automatically, and thus there was no need for, or provision of, one or more red windows on the back. (The camera could not be used for 6×4.5.) Secondly, a larger finder with a bright frame with marks for parallax (although not moving to adjust for parallax).

A third claimed advance was a lens that was advertised as by Zunow, famous for its f1.1 lenses. The "Zuminor" lens was indeed made by Zunow, but Zunow had no experience of lenses for purposes such as this. A new employee at Zunow was Kunitomo Kenji (国友健司), who had designed the "Ofunar" lens for Ōfuna Kōgaku's Ofunaflex and Ofuna Six cameras, and a deal was struck among Zunow, Ōfuna and Takane whereby Zunow would use the Ofunar design and Takane would manufacture a batch of Mine Six IIF bodies for export as Ofuna Six cameras.
