<p>PURPOSE: To prevent damage such as the peeling of the joint wire or coating of another signal cable, etc., from occurring even when one of signal cables is drawn out to the outside by gearing the the gearing parts of first and second cable unwinding rollers with each other when the signal cable is pulled and unwound to the outside of a cable reel. CONSTITUTION: The first and second cable unwinding rollers 107, 86 are formed in such a way that at least one signal cable of cable bundles 61 set as a pair of plural signal cables is pulled to the outside of the cable reel and unwound from the cable reel. At this time, they are rotated synchronously in directions opposite to each other by engaging the engaging parts 113, 114 mutually, and another signal cable out of the cable bundles 61 can be unwound to the outside of the cable reel. Therefore, the winding of another signal cable on the cable reel when one signal cable is pulled to the outside of the cable reel can be prevented from occurring.</p> |
