Horizontal lifting system
Posted: 24 Aug 2009, 16:52
I found the Instructable yesterday and just love the first couple of scanners. I have been busy digitizing some books using photocopiers and scanners because I thought there was no other (cheap) way of doing it. Boy was is wrong
I am thinking of building my own scanner and just happen to have a Canon A590 IS. Only one for now, but if my scanner is any good I’ll buy me another one.
The systems with the cameras fitted to the platen are my favorite. Only adjusting the camera once and no autofocus needed. Also the systems with a sliding book holder which prevents the book from shifting in the pictures from the first to the last page.
I was thinking of ways to lift the whole platen and cameras horizontally. When looking at the Scott Russell Straight-line motion mechanism I realized that I’d seen this before in scissor lift systems and that it might be useful. I’ve made some sketches of my idea.
I realize that it’s not sturdy sideways but that’s not needed when the book is allowed to slide in that direction. Lengthwise this solution looks very sturdy to me. The vertical posts can also be made sturdier by fixing it to the horizontal slides with some diagonals. On the other hand ... maybe it can do without the horizontal posts at all, also saves two sliders.
What do you guys think? Looking ok?
