<p>PURPOSE:To lower surface pressure between a tape and a video head and to prevent oscillation in the exist side of the tape by providing a projecting part with slightly cut-remaining a spot, where the tape is separated from a lower cylinder, when the lower cylinder is worked. CONSTITUTION:By slightly remaining the tape guide surface of a lower side cylinder 21 when it is cut, a projecting part 25 is provided in a place, where the winding of a magnetic tape 11 is finished, on the outer circumference upper edge part of the lower side cylinder 21. Then, the magnetic tape 11 is wound on the projecting part 25 and separated from a revolving cylinder 3 in the spot of the projecting part 25. Thus, since the magnetic tape 11 to be wound to the outer circumference of the revolving cylinder 3 is separated from the center of the revolving cylinder 3 in the part of the projecting part 25, contact pressure between a magnetic head 6 and the magnetic tape 11 goes to be small in the place of the projecting part 25 and shock, which is generated when the magnetic head 6 is separated from the magnetic tape 11, is lowered. Then, the oscillation is prevented in the exist side of the magnetic tape 11.</p> |
