Magnetic-tape apparatus comprising a threading mechanism for the displacement of a magnetic tape and a belt so as to form tape buffers

摘要

A magnetic-tape apparatus is disclosed which includes a drive mechanism for driving a magnetic tape and tape reels, a magnetic-head mechanism buffer mechanism comprising a belt (8), guide elements for guiding the belt in an operational position, a tape-threading mechanism which during the thread-out phase threads the tape out of the cassette and wraps it around the magnetic-head mechanism and during the thread-in phase threads the tape into the cassette. A belt-threading mechanism threads the belt between the guide elements into the tape path during said thread-out phase and brings the belt back into its initial position during the thread-in phase. The apparatus (1) also includes a mechanism for moving the belt-threading mechanism in such a way that the belt can be brought into the desired operational position and into said initial position.
