Here's the picture, sorry for the quality, but I couldn't find my camera.

Yes, the 9th hole is the timing hole, the tape is 2,5cm wide
I want to build a reader.
I could scan the tape, but I don't know how to decode the picture.
@cr0sh
It's a CNC programm tape.
I think, the data is encoded in 7 bit ASCII with the 8th bit being parity, based on my small research about punched tapes, however I don't really understand the encoding until now, I will have to search for it.
The problem with scanning is the same thing: how?
I found somebody who has built a paper tape reader, but he is selling it quite expensive:

I have asked some people who worked with tapes, what they are encoded in but they haven't replied yet.
Until then, I would want to build the hardware.
@retrolefty
It is a way to do it, but I think it is overcomplicated, to use IR diodes, because of the need to pulsate IR diodes.
@justone
Yes, it is a one-time read, and used readers are expensive too.
I do not know any cnc shop located nearby.
I live in Satu Mare, Romania: http://g.co/maps/z2x24
Every Company that used paper tape readers, has either sold them or they were thrown away.
@MartinH
It is a possibility to make it via metal surface contact, but I don't know how to write the code, so that It reads characters indifferent from speed, because I want to move it by hand.
Buying a used printer would cost...
@Grumpy_Mike
It would be really great to make it as cheap as possible, because I need only a one-time scan.
I don't know how I could decode the video feed.
Thanks guys for the quick answers
