Fig. 5 is a perspective view of the core; Fig. 5 is a partial cross-sectional view showing the state in which the winding core has further rotated slightly due to inertia after the tape has been unraveled; Fig. 6 is a perspective view of the core;
The figure is a partial cross-sectional view showing a state in which the winding core is slightly inverted and stabilized after rotation due to inertia. Figures 7 and 8 show the position of the sandwiched part of the groove provided in the winding core on a line passing through the center of the winding core. Figure 7 is a partial cross-sectional view showing the state at the moment the tape has finished unraveling, and Figure 8 is a partial cross-sectional view showing the state in which the core has rotated slightly due to inertia after the tape has finished unraveling. 9 are perspective views of a tape base end and a winding core according to a conventional example. 1...

Claims

[Scope of utility model registration request]

A through hole 4 is provided in the base end 3a of the tape 3 that is wound around the outer circumferential surface of the core 2 rotatably attached to the support frame 1. A leveling rod characterized in that a groove 5 which is recessed and into which the base end of the tape 3 is fitted is provided, and a locking pin 6 which is inserted into the through hole 4 of the tape 3 is protruded from one side wall of the groove 5.
