Whilst this website is about Taiyodo Koki and the Beauty Camera Company's 35mm cameras, the companies also made a number of other non-35mm products. Further details of each can be found at the websites listed below.
Sub-miniatures (1948 to early 1950s)
Taiyoko Koki's first cameras were sub-miniatures, starting with the 1948 Meteor. There doesn't appear to be an agreed definition of "sub-miniature", but in the case of Taiyodo's models, these were cameras that used either 16mm or 17.5mm film. The best source of information on Taiyodo sub-miniature cameras is probably Camera-wiki (16mm Spy 16 and Beauty 16, or 17.5mm Meteor, Vestkam, Epochs and Beauty 14).
6x6 Folders (1950 to mid 1950s)
6x6 Twin Lens Reflexes (1950 to mid 1950s)
Taiyoko Koki made TLRs alongside their folders. There were named Beauty, Beautyflex and Beautycord. Whilst these cameras are highly collectable, good information is a little scattered and hazy. I recommend Barry Toogood's "TLR Cameras Website", as the best English language source. The Chinese site "Dujingtou.com" is also very good, with a second page of information about Taiyodo made cameras sold under other names (note that the writer also reflects some doubts over the claim that Taiyodo Koki became bankrupt). It seems that Taiyodo Koki were also the manufacturers of Fodorflex, Gen-flex, Wardflex, the SCL Photoflex and USC Auto Fifty TLRs.
6x6 Single Lens Reflexes (1954 to mid 1950s)
Taiyodo Koki made just two 6x6 SLRs; the Beauty Reflex I and II. For more information, once again, the best source is Camera-Wiki's Beauty Reflex page.
M42 Zoom Lens (1962)
The Beauty Camera company made one of the earliest Japanese zoom lenses, which was built with an M42 Praktica screw fitting. The 50-100mm f/3 "Zoom-Biokor" featured a direct lever zoom mechanism that was completely different to the twist of push/pull zoom lenses that were to become conventional. Details can be found on the Omocane World website (written in Japanese).
Other projects (1963)
I read on a Japanese photography Blog, in an article about the closure of the "Camera Taiyodo" shop in Tokyo, that "in 1963 ... there are records that a 35mm camera with a radio was prototyped". Not such a wacky idea as you might first think; other manufactures actually made such things.
In 1948, the Automatic Radio Manufacturing Company of Boston made the "Tom Thumb Camera Radio"; an 828 pseudo-TLR combined with a valve radio.
The "Ramera" (a.k.a. Bell Karma) was a combination of a transistor radio and a 16mm camera (i.e. a camera in a radio, rather than a radio in a camera), made by Kowa in 1959–60.
The 1962 "Sonocon 16" was a sub-miniature made by Minolta, which incorporated a transistor radio.
Finally, the "Vivitar Radio 110" was a 1970s model that combined a compact camera with a built-in radio and flash.
