Glossing over the complete document, the engineers had their work cut out. They re-designed the shutter and mirror drive mechanisms to fit in a smaller volume and they also considered weight distribution, momenta and torque direction of the moving parts, probably aiming to reduce mirror and shutter slap. It is probably standard engineering practice to consider all this, but maybe they figured out some ingenious cam mechanism along the way.

Seems like patent is related to re-arranged mirror drive mechanism to achieve smaller size and reducing vibration/slap, increase speed of rotation (frame performance). Seems like they devised a new way or moving the mirror. That is, if I'm understanding all this correctly...

This is not K-3, as the patent document mentions inclined top display, and you can clearly see that the prism box is much bigger than on K-3

From statement nr. [066] :

" The camera 10 shown in FIG. 1 is a digital camera using the image sensor 21 as a photographic light-receiving medium; however, the present invention can also be applied to a camera using silver-salt film as a photographic light-receiving medium. "

I think it's just a generic pattent for the shutter mechanism. If it was specific to the new FF-camera the prototype 3D-print would definatly have the inclined top display (since this patent is already 1.5 years old) and judging by the photo's it doesn't.

Yep I think its the new anti mirror shake mechanism first seen in the K3

But that doesn't mean it won't apply to future models

Why would the document have FEB 5, 2015 if this is about K-3?

OK, maybe !!! But with a prism that size there is no room for a flash !!!

The prototype is only a prototype!

As you can read in statement nr.

", I don't believe they're referring to APS or 110 film.

Because patents take a long time to process. The U.S. now has a first-to-file patent system, so the filing date is key - excluding an earlier filing, they have the rights in the process sewn up from the 2013 filing date and can begin rather confidently marketing it the day they filed, even if the patent is still pending.

There is. Take a look at the photos of the K-3 innards above. The prism bracket matches exactly. Now take a look at a front view of the K-3 body and compare the lens mount positions. That prism easily fits under the flash housing.

Either way, the patent, as others have stated is not for the attached camera, but for the anti-shake mechanism only. The reason film is mentioned is because Ricoh wants to maximize the breadth of the patent and to be able to demand licensing fees in the unlikely event someone else ever does make a film-stabilized camera body. I seriously doubt they have plans to build such a camera themselves. And 110 and APS film are silver-salt based, as is 35mm and MF. They are just cut down to different sizes. The patent applies to any sized sensor and any sized film frame and can be scaled up and down in size as long as the underlying mechanism is essentially the same.
