<p>PURPOSE:To offer a rotary head cylinder device for a video tape recorder in which a tape does not form a recessed part, because it is the cause of damaging the tape that the tape is pushed in the inner part of a head window part and forms the recessed part in the rotary head cylinder device. CONSTITUTION:A hole 38(2nd aperture part) is provided on the upper surface of an upper drum and a 1st aperture part 18 and the 2nd aperture part 38 are connected, so that air is sucked from the 2nd aperture part 38 and allowed to blow out by the 1st aperture part 18 to prevent the recessed part of the tape from being formed.</p> |
