Two page turning mechanisms

Built a scanner? Started to build a scanner? Record your progress here. Doesn't need to be a whole scanner - triggers and other parts are fine. Commercial scanners are fine too.

Rifle through pages to break any bonds between pages. Vacuum suction should pick up one page only since stuck pages are unstuck prior to scanning (hopefully). The movement of the turner is powered by the counterweight pully system of the platen. Count pages in book and match with number of files (quick way to verify if any pages missing rather than check each page manually.

I did not flesh out the attachments to the pulley system in the drawing but one part of cable should be attached to the rear and the other to the front such that as the platen goes up the page turner moves to the right and when the platen goes down the page turner goes to the left. By adding posts to the front of the suction tube extending out through the travel guide you can work out a method to attach the left cable.
