Two-way anti-reverse transmission 1b

This is an embodiment of the mechanism shown in “Two-way anti-reverse transmission 1a”
http://youtu.be/wZjoNIkYQqM
Pink input shaft transmits rotation to output green shaft in both directions.
Reverse transmission is impossible because rollers wedge between the fixed outter rim and the green shaft.
The mechanism has self-locking feature like worm drive but transmission ratio is 1/1.
It can be used for motion control system where servo motor needs a rest (interrupting electric supply) when motion control is not required.
