The counter unit cover 80 is coupled to the axle 60 in a state where the coupling wheel 83 is interpolated into the hollow inside of the axle 60 .

And by the load and gravity of the counter unit cover 80, the roller 71 provided on the lower side of the counter unit 70 coupled to the counter unit cover 80 is in contact with the outer surface of the film bundle, and is wound around the film bundle. When the film is rotated while unwinding, the roller 71 in contact with it rotates together, and counts the number of rotations by performing one count per rotation.

That is, the counter unit 70 includes a roller 71 on the lower side to measure the number of revolutions.

The structure of such a counter unit 70 can be amplified through [Table 2].

Meanwhile, although not described, the rotation value of the motor m may be employed based on a value set through a separately provided system, and the motor m may be configured to operate based on the set value.

However, since the present invention has a main feature of the device, technical matters regarding this can be employed based on the expertise of those skilled in the art at the time of filing.

Although the present invention has been described with the above examples, the present invention is not necessarily limited to these examples, and various modifications may be made within the scope without departing from the technical spirit of the present invention. Therefore, the examples disclosed in the present invention are not intended to limit the technical spirit of the present invention, but to explain, and the scope of the technical spirit of the present invention is not limited by these examples. The protection scope of the present invention should be construed by the following claims, and all technical ideas within the scope equivalent thereto should be construed as being included in the scope of the present invention.
