Claims

[Claims for Utility Model Registration] 1. A magnetic tape is stretched between a supply reel and a take-up reel along a longitudinal opening at its leading edge, and the bifurcated front end is self-retained by elasticity to spread the magnetic tape along the longitudinal opening. a direction in which the dust-proof tape is engaged with the rear end of the dust-proof tape and separated from the longitudinal opening when loading a dust-proof tape cassette comprising a dust-proof tape spread inside the tape so as to be slidable at right angles to the longitudinal opening; dust-proof tape removing means for sliding the magnetic tape from inside the magnetic tape stretched along the longitudinal opening; 1. A cassette VTR comprising: a magnetic tape guide means for winding the magnetic tape around a magnetic head rotating drum by moving the magnetic tape while moving the tape, or by extending the magnetic tape after moving the tape and winding the magnetic tape around a rotating magnetic head drum. 2. A request for registration of a utility model characterized in that the magnetic tape guiding means is provided with a tape guide support arm consisting of an outer arm and an inner arm that each support a tape guide roller at their outer ends and are telescopically fitted into each other. A cassette VTR according to item 1.
