Well, it took a while but I got all 2751 pages scanned and the scanner worked great through the entire process.

Re: A Scanner for books with text VERY close to the gutter.
That is awesome! How long did it take you to train FineReader for this? The reason I ask is that I tried training FineReader for an English-Latin dictionary that had accented characters plus greek letters, and after going through several pages of long and boring work, the thing couldn't tell the difference between S and s.
After training, modulo the S/s problem, it would get the pages I trained correct... and then fall down completely on the pages I didn't train. Presumably FineReader needs many more pages to train on, but it's so FUCKING BORING.

That's an excellent build, Nice and Simple. Would you mind sharing pics from the camera back side. Just want to see what you used for the hinge. And also from the bottom glass side. What did you use to make the groove in the side panels? Thanks.

I never said I had ORC'd them all. I'm still working on it. You are right, it's boring has hell. I find that if I do the training on the parts it's having trouble with, it works better.rob wrote:That is awesome! How long did it take you to train FineReader for this?

There are two character pairs the s & f and the u & n that I I'll probably have to read every page to double check it.
I just used common 3 1/2" door hinges for the pivot attached to the side facing the glass. Nothing critical about it.smartechs wrote:That's an excellent build, Nice and Simple.

I used a table saw for the 3 sided frame surrounding the glass. A little silicone at the bottom corners to hold it all together.

Thanks for the details.

Are you planning on building one?
Re: A Scanner for books with text VERY close to the gutter.
Dear Jthomas,
I am sorry I wasn't able to reply back to your message, its been a busy month and never got a chance to check the website. I did make one, thanks to you. A larger version of it. My platen size is 25"x20", which I used to digitize a 1950 page manuscript. It worked perfectly for it. I will try to post a picture. Thanks again.

I know, this threat is OLD, but maybe I can get a response
As I want to build a scanner very similar to the one Jthomas built I have some questions:
Which improvements have you done till now? What about the lighting?
Last but not least: Are you still using it or do you have a new model, which is somehow better than the old type?
Hope I get an answer
Regards,
Jakob

These images of the model reminds me of the Quartz model I see.
With it you can get more text when the text is too close to the gutter, but the tricky part of it is scanning without harming the book, and most of them will be if they're opened more than 90º.
In any case, one key is to get the pages to be flatten from the book spine itself, so flattening the text with a glass is not enough, you must get the entire book in a position where the pages block is not turned or curled at any point. You make this at the same moment you choose the angle of scanning. Its the way to do it specially if you want to OCR the text lated, in order to avoid distorsions.
With this kind of 'unilateral' preset you will want to to all the left pages before going for the right ones. That kind of book are the slower to scan.

Re: A Scanner for books with text VERY close to the gutter.
if this thread is still active has anybody the dimensions of this design?
