The Semi Elka (セミエルカ) is a Japanese 4.5×6 camera, about which almost nothing is known. It is mentioned in the official list of set prices published in November 1941, under the names "Semi Elka I" and "Semi Elka II". In this document, it is attributed to the company Banno Toyoji Shōten, which is otherwise unknown. The Semi Elka does not appear in an earlier price list compiled in October 1940 and published in January 1941, probably because it was not yet produced.
The Semi Elka was perhaps related to the earlier Elka shutter, which sometimes has T.B.C.T. markings or a TB logo. (The "TB" initials might stand for Toyoji Banno, but this is merely a guess.) It might also be related to the company Fuji Kōgaku, which made an Elka accessory rangefinder c.1936.
