Claims

[Scope of utility model registration request]

It has a tape presser at its tip that restricts the vertical movement of the magnetic tape running on the circumferential surface of the video cylinder, and the tape presser is held in a groove formed in the upper part of the video cylinder, and a part of the tape presser is held from the side surface of the video cylinder. A tape presser spring is provided that positions the tape presser so that it is exposed and presses the tape presser downward, and the middle of the tape presser spring moves vertically within the groove in response to the vertical movement of the tape presser. In the video cylinder configured to swing, the groove portion formed in the video cylinder includes a guide groove formed with a groove width that allows the tape presser to move only in the vertical direction, and a guide groove formed in the video cylinder with a width that allows the tape presser spring to move only in the vertical direction. The video is characterized by comprising an relief groove formed from a groove wider than the groove width of the guide groove so that the tape presser spring does not come into contact with the video cylinder when it swings within the groove.
