Abstract

A description is given of tape guiding elements for video magnetic tape apparatuses, in particular for guiding the magnetic tape of tape cassettes with the cassettes own tape guiding pins, which direct the magnetic tape inside the cassette from a supply reel to a take-up reel, it being intended to avoid adversely high frictional losses and increased power inputs for the winding motors. The way in which this is achieved is that, after loading the tape cassette, on both sides of the winding reels the apparatuses' own tape guiding elements, arranged on a swivelling device, engage behind the magnetic tape in the cassette and, by swivelling the tape guiding elements, draw the tape partially out of the cassette in such a way that it is guided completely detached from the cassette's own guiding pins. Such a construction which has the apparatus take over with its own tape guidance from the tape guidance of the cassette, having a swivelling device with specially designed tape guiding elements, makes it possible in particular in the case of fast rewinding functions of the tape to reduce the input power of the winding motors and, in addition, permits accurate tape guidance, in particular vertical guidance.
