るバックテンション機竺。In a cassette type VTR in which a guide cylinder is disposed on one side of the cassette in a direction substantially perpendicular to the tape pulling direction of the cassette, a rack plate movable in the substantially perpendicular direction is engaged with the rack plate. a pinion gear provided on the pinion gear, a notch provided in the pinion gear, a lower back tension lever coaxially supported with the pinion gear, a protruding piece provided on the bar and loosely fitted in the notch, and the back tension lever. Back 7 placed on the tension lever
-7, the back tension pin is located in the notch of the cassette when the tape is not loaded, and the spring is stretched between the pinion gear and the rosette tension lever. When the rack plate is moved to a predetermined position, the back tension lever is rotated to a predetermined position and is allowed to rotate within the notch range. Tension machine.
