The feed shaft 13 is provided on the rotating portion 12 and rotatable with the rotating portion 12, and the feed shaft 13 is used to place the film 8, it being understood that the number of the feed shafts 13 is two or more, that is, the film 8 placed on the rotating portion 12 may be two or more. The sensor 2 is arranged on the equipment holder 11 and faces the film 8. The sensor 2 may be a distance measuring sensor such as a photoelectric sensor, an infrared distance measuring sensor, an ultrasonic distance sensor, or the like, which may be disposed toward the reel of the film 8, measures the distance from the surface of the reel of the adhesive tape 81, and transmits to the controller, so that the amount of the film 8 is obtained by comparing with a preset distance, for example, when the adhesive tape 81 is still more, the distance between the sensor 2 and the surface of the reel of the adhesive tape 81 is smaller, and when the adhesive tape 81 is about to run out, the distance between the sensor 2 and the surface of the reel of the adhesive tape 81 is greater than the preset distance.
