Episkop skoptikon
Episcopal (επι - na + σκοπεω - see) - a device enabling projection (projection) on a projection screen or eg the wall of an image room resulting from reflection from illuminated material to a presentation, enabling it to be enlarged, eg, paper pages publishers (newspapers, books, etc.) or specially designed boards for this purpose. Episcopal is the prototype of a more universal device - epidiascope, which in one casing connects the episcopal with a dioptop also allowing the presentation of enlarged materials that can be illuminated by passage (eg various types of films).
