Abstract (en)
[origin: WO8101907A1] Indicator device for cassettes loaded with magnetical information carriers, in which one of the faces of the cassette defines a window, an indicator block is located and guided for a sliding movement between at least two discrete fixed positions in the window, a positioning means is provided to fix the indicator block in said discrete positions, and the free surfaces of the window covered or uncovered by the indicator block are in respective planes with different heights so that the height difference can well be detected by appropriate detecting means.
