Origami Scanner- a folding book scanner
Origami Scanner- a folding book scanner
I thought I would open this topic. I am posting overmuch in the," Input on the best way to build a portable scanner" thread on what I would build. I don't think that was the intention of the thread... in hindsite of course. Sorry about that o3h1p. So I will start this thread and move much of the information here or restate it here.
Please feel free to suggest or argue what you think would work best in this sort of a scanner. The drawings will express what I am thinking of in the best way I can present those thoughts. To start that process... I will restate what I first said in the other thread:
I have been doodling with the idea of making a folding scanner. The ideas are very rough. In gerneral I am working from the idea of a box that folds in on itself. Much like a cardboard box with no top can be cut at the corners and then be made to fold in on the bottom (assuming for a moment the box is of such dimentions that the sides are no deeper than the bottom is wide). If one takes the open box and sets it on the shortest side with the open end facing out, that is the basic model of the scanner scaffold or carcase(nothing new really). The cradle would be made as minimally as possible in the bottom side of the box using slides to allow side to side movement. Much like the new standard scanner. The angled book rack/ cradle would not be permanently set but rather fold flat by making its support struts fold along side the primary rack (no triangles underneath of it). The platen on the sliding rear upright would fold in the opposite way from Danial R.s' 3rd gen platen so that it might fold flat while still attached to the upright. A set of telescoping supports would hold it either flat or in its 90 degree functional form. A hinge at the upright suport to the telescoping supports would allow the flat platen to fold up flat on the back of the "box". Once everthing is collapsed flat the "box" then folds flat. The lighting would be placed on the top and the cameras on the sides in the completed scanner. Cameras to be removed as folding is needed. I believe the whole will fold into a sort of flat portfolio or suitcase. This is a very rough description and I will post 3 dimensional drawings asap. I have started calling this the origami scanner.

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.- ceeann1

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.- ceeann1

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.
The supports, if you look very closely, will detach and the cradle should fold flat. This will require more space horizontally than is shown. The thumbscrew allows the book width to be adjusted. The attachment points where the the cradle flattens are a type of knife hinge. A permanent attachment point hinge. Where the supports are allowed to detach I would use an aircraft type nut plate that is riveted to the supports. A bolt would hold things fast when not being moved around.- ceeann1

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
I really like this flat platen idea... I think it's a really nice take on the folding platen concept. And it's simple to make, with a hinge there, it makes good sense.

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 a couple of views of the front articulation of the platen. These could be cast of aluminum or more simply made in a slightly different form from sliding channel and bolts.

Re: Origami Scanner- a folding book scanner
This is a picture of the rear articulation of the platen. It is really the key to getting the platen to fold. The next image will show this in more detail.

Re: Origami Scanner- a folding book scanner
This is an exploded view of the rear articulation of the platen. It has sleeves that the bolts fit in to allow this to slide. All the sleeves are through and through and are only fit to slide in the elongated channels.
