ABSTRACT:
A tape wrapping mechanism for a rotary head type VTR wherein a tape pulling post is provided on a rotary ring mounted rotatably on the outer periphery of the cylinder, a rotary ring is rotated so that the post rotates along the outer periphery of the cylinder to pull out the tape from the cassette and wrap it around the cylinder and the rotary force of the rotary ring is such that, when the magnetic tape is wrapped at a predetermined wrapping angle, a pinch roller is automatically pushed toward the capstan with the tape therebetween. With this mechanism, a state capable of recording and reproduction is realized and the abutment of the pinch roller against the capstan is automatically released by a reverse rotation of the rotary ring when switching from the recording-reproduction state to the stop state.
