The one problem I see right away is your cradle doesn't support the spine of the book.
I thought a long time over this problem, but I think, I found a solution (not build, only an idea)
I think everybody saw this Video: http://www.youtube.com/watch?v=pb6E4Hrgi9Y
The Pages are sucked via some kind of vacuum-cleaner-engine onto a corner. inside this corner is some kind of camera or scanner-device. Doesent matter for me. The whole thing is moving upwards and finally a small air blast is turning the pages over.
This is my idea: Ignore the scanning unit, and turn the pages with a vacuum cleaner, some thing to move the corner where the pages are sucked at and a small air-blast-thingy (perhaps use the exhaust from the vacuum cleaner)
This page-turning device must shurely be moved away from the book, to allow the Glas-Corner to get on the book to flatten the book for making the photo.
What do everybody thinks? I think one would only need 3 Axis (one for moving the Glas-V vertical, one for moving the page-turning-thingy vertical, and one thing for rotating the page-turning-thingy out of the way around a vertical axis (maybe even move it paralel to the Z-Axis)
Y-Axis = Vertical
X-Axis = Book Left/Right (not needed, moves automatically when the glas-corner is moved down)
Z-Axis = ... the other Axis
What does everybody think?
I think, this is a much more cheap solution than this stuff: http://www.youtube.com/watch?v=UyB5c3S4vzc They used a shitload of different axis and stepper-engines ... I think nobody is able to build this without studing rocket science and having thousands of dollars budget, several CNS-Mills ...
two things: this is just an idea to discuss, I have not yet started to build my first bookscanner ... so this might be a little early ... but this board is for discussion of ideas...
second: my native language is german, and my english is not so good, as I wish it was ... so dont wonder about strange descriptions, wrong words (with a onyl nearly matching meaning) wrong grammar ... I hope this is ok for you all ...
If there are better words to describe what I mean .. tell me!
