Re: Origami Scanner- a folding book scanner

This is the platen in its full suspended form, at this moment, with front and back articulations to allow it to flatten. I believe this will need a support of some sort on the tip of the V to keep it from sagging. It can not be much because it must not interfere with the folding.

Re: Origami Scanner- a folding book scanner

This is the platen as I imagine it will fold. the dark things on the bottom are hinges. I do not intend it to fold all the way around, just to flatten. The clear material will probably be lextan and will no doubt need a cover on it for when it is folded.

Re: Origami Scanner- a folding book scanner

This picture shows the cradle from the front and some of the side is missing. I believe the drawing needs modified to allow the bottom to move more. cradle front.jpg The supports, if you look very closely, will detach and the cradle should fold flat. This will require more space horizontally than is...

Re: Origami Scanner- a folding book scanner

This picture shows a slighly more advanced version of the carcase in its folding configuration, but without a platen. The view is from the back looking down to the front. The picture is labled to orient the view.

It also has a numbering to show how it might fold up.

Re: Origami Scanner- a folding book scanner

This first picture is how I first imagined a carcase for a book scanner with side and back supports.

I imagined a light system of some type attached to the top. Perhaps an led system that lends itself to flatness.

Reply to spamsicle: Ok that is what I thought keystoning ment. An optical distortion, in effect. I always intended to keep the plane of the cameral lens parallel to the plane of the book page.

Re: Let's talk about Lighting

I was rereading the thread and it occured to me to ask how many folks have actually made reasonably effective and relatively inexpensive LED lighting systems for a scanner? Is there a count of these somewhere? How repeatable is any one design at this point? HELP!! I don't really know how to answer t...
