PROBLEM TO BE SOLVED: To provide a residual amount decrease notification device for a closure, sensing and notifying decrease of a residual amount of the closures wound around a reel.SOLUTION: A notification device 11 provided in a binding machine 18 binding a packing bag with a closure 4 and sensing residual amount decrease of the closures 4 wound around a reel 14 includes at least: a photoelectric tube 15 to which a closure roll wound around a disk-like core material is replaceably set, and which projects light onto the closure roll set to the reel 14 from which the wound closures 4, 4, etc. are sequentially delivered to the binding machine 18, and which receives reflected light; and a notification device 16 sensing and notifying the decrease of a light receiving amount of the photoelectric tube 15. A color of the core material is colored in a darker color than a color of the closure 4, and the projection of the photoelectric tube 15 changes from the closure 4 to the core material, so that the photoelectric tube 15 senses that the light receiving amount of the reflected light decreases, and the notification device 16 notifies it. |
