<p><P>PROBLEM TO BE SOLVED: To prevent cable disconnection or load application to a drive source when a cable is wound up in the cable handling equipment for a traveling body. <P>SOLUTION: A cable 4 is fed out while being held by means of a feed roller 30 and a pinch roller 35 supported respectively at the rocking ends of first and second levers 27A and 37A supported rockably. A planet gear 64 meshing with a sun gear 32 for driving the feed roller 30 is pivoted on a third lever 63, and the third lever 63 is supported rotatably by the first lever 27A through a shaft 31 which is coaxial with the sun gear 32. A cam follower 70 pivoted on the third lever 63 engages with the cam face 72a of a cam 72 provided in the pinch roller 35. When the cable is wound up, the third lever 63 rocks through the planet gear 64 and the cam follower 70 engages with the cam face 72a thus holding the feed roller 30 and the pinch roller 35 in a state separated from each other. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
