Abstract
A reinforcement binding machine capable of detecting, by the rotation of a reel, that wire on the reel is consumed and the reel, the reinforcement binding machine wherein an interrupter is installed in the cassette case of a binding machine body, a cover is rotatably held on a reel mounting shaft, an opening part is formed in the cover, a projection is formed on the reel and fitted into the opening part, and a color with a lightness different from that of the cover is applied to the projection to detect the rotation of the reel by the interrupter.
Claims14
A reel mounted to a reel mounting shaft formed on a reinforcement binding machine having a sensor for detecting rotation of the reel, the reel comprising:
- a pair of flanges;
- a recess formed in a surface of the reel facing the sensor;
- and
- at least two detection objects formed at a bottom of the recess, each of the detection objects having a different physical feature;
- wherein the sensor of the reinforcement binding machine receives a different signal from each of the detection objects;
- wherein the difference of the signal is caused by the difference of the physical features of the each of the detection objects;
- and
- wherein the at least two detection objects comprise protrusions.
