In addition, by the weight and gravity of the counter cover 80, the roller 71 provided on the lower side of the counter 70 coupled to the counter cover 80 is in contact with the outer surface of the film bundle, and the film bundle is wound. When the film is unrolled and rotated, the roller 71 in contact with it rotates together, performing 1 count per rotation to count the number of rotations.

That is, the counter 70 includes a roller 71 on the lower side to employ a conventional one that measures the number of revolutions.

The structure of the counter 70 can be amplified through [Table 2].

On the other hand, 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 in the device, technical details thereof can be employed based on the expertise of a person 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 may be variously modified and implemented 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 idea of the present invention, but to explain, and the scope of the technical idea of the present invention is not limited by these examples. The protection scope of the present invention should be construed according to the following claims, and all technical ideas within the equivalent range should be construed as being included in the scope of the present invention.
