The Minoriflex is a Japanese 6×6 TLR, sold and perhaps made by Rokuwa Shōji in 1950 and 1951.
A number of versions are listed in a March 1950 advertisement by Japan Photo Service Co., Ltd.
The Minoriflex I has no auto-stop advance, a "Torionsu" (トリオンス) f/3.5 viewing lens and a Super-Rapid shutter (T, B, 1–500). It was available with the following lenses:
The Minoriflex II has auto-stop advance and a Lausar S f/3.5 viewing lens; it was available with the following lens and shutter combinations:
- Lausar S f/3.5, Super-Rapid shutter (¥18,500);
- Hexar f/4.5, Super-Rapid shutter (¥23,000);
- Tessar f/4.5, Compur shutter (¥23,000);
- Tessar f/3.5, Compur shutter (¥23,000).
The use of German lenses and shutters at that time is surprising. These were possibly coming from old stocks of parts.
No surviving example of the Minoriflex has been observed so far.
