ABSTRACT:
Apparatus for reproducing information recorded on a flexible, opaque tape in the form of successive images having a high resolution such that they cannot be read by the naked eye.
The apparatus comprises a tape drive for advancing the tape to and through a presentation zone. A luminous source provides a luminous scanning flux directed towards the presentation zone. A photo-sensitive device receives a beam of luminous flux reflected from the image on the tape at the presentation zone and transforms the variations in luminous intensity into electrical signals.
If the successive images are television fields, then the electrical signals are used to produce a visible image on a television receiver. Alternatively if the images are documentary records, the electrical signals are fed to a viewing apparatus for reading by a user or copying.
