One way rotation and linear reciprocation

Input: blue shaft of narrow gear (20 teeth) and wide gear (19 teeth) rotating regularly.
Output: orange shaft of orange gear (20 teeth) and cam follower performing one way rotation and linear reciprocation.
Pink cam of pink gear (20 teeth) is idly mounted on the output shaft.
Red spring and green curved bars maintain the cam-follower contact.
There is a speed difference between the pink and orange gears.
A double stroke (forward and backward) of the output shaft corresponds 10 revolutions of the input shaft.
