Claims

[Scope of utility model registration request]

2 supported so as to be able to come into contact with the cylindrical surface of the head drum of the VTR.
A book roller, a roller support shaft that rotatably supports the roller, a base that holds the roller support shaft, and a roller support shaft that is swingably supported by one of the two roller support shafts. and a measuring element having a measuring element surface parallel to the generating line of the head drum when pressed so that the generating line of the two rollers coincides with the generating line of the head drum, and the measuring element is pushed up by the head tip. A VTR head chip measuring gauge, comprising: a micrometer attached to the base so as to be able to measure displacement when the VTR head tip is moved.
