Canon patent for a dSLR that can take EF-M lenses (if I got it right)

I am not sure I understood this patent correctly. Machine translated Japanese patent literature is never an easy task to get. Any help is thankfully accepted.

However, Canon filed a patent for an SLR that can switch the position of the sensor (108 in the second image). If you look at the first image, you can see that the sensor stays in a different position and that the mirror (104) is there were the sensor was.

What about the flange distance, which is different for EF-M and EF/EF-S lenses? The Japanese text mentions an adapter that has to be used when using EF-M lenses.

I am really not sure I got this right. It appears to be a camera body for some sort of transition from dSLR to mirrorless.

What do you think?
