Abstract
An apparatus for coding and/or decoding a document, comprising a light path (27,28,29) formed of optic fibres and capable to direct light from a lens for focusing the light from a document to be coded or decoded to a light-sensitive device for recording a coded and, respectively, decoded copy of an uncoded and, respectively, coded document. The light path (27,28,29) consists at least along a section of a coding and/or decoding unit (29) comprising a code disc (32) provided with optic fibres (62), the respective ends of which are connected to a first and, respectively, second light guide (27 and, respectively, 28), associated with the light path. The fibres (62) at one end surface of the code disc (32) have a different mutual order than at the other end surface of the code disc. The fibres (62) of the code disc (32) and the fibres (60,61) of the light guides (27, 28) at the end surfaces of the code disc (32) and, respectively, at the ends of the light guides ( 27,28) are located along a circle.
