Hi George,
A 'copy stand' is just one of the devices you can use for copying. Many different variations. One I remember, was something like a photographic enlarger, a bed, with column and bracket (adjustable) with a camera mount (instead of enlarger head), so the camera film plane was // to the bed. It had lamps placed at each corner, above the bed. Once set up, you simply put the papers on the bad and fired the button. Even if you have a 'black and decker' you can make something similar.
A cheap tripod, with the camera hung underneath, with some lamps clamped to the legs? If you white balance, ordinary tungsten lamps will do, or daylight fluorescent tubes - (think garden centre or pet shop), or LED down lighters. Of course you can google around, and buy something off the shelf, but by the time it arrives, you could have made your own.
Or, prop the picture on a chair, and use your camera as normal. You do not need flash, you do not need bright lights, you do not need reflections, generally. With some post processing, you can get some very good results.
A flat bed scanner does not work for non flat surfaces - e.g. oil painting, if done with a knife, say. It has shadows, which vary in direction as the scan head/lamp moves. I have often scanned printed circuit boards, to show component layouts, it is useful, but not an accurate reproduction (Something like Google - earth, but on a smaller scale)
Best wishes,
Ray
