PROBLEM TO BE SOLVED: To enable repetitive connection switching with high reliability without the congestion of connecting cords by finding the lowermost point of the connecting cords to be aligned, inserting an insertion and removal finger into the connecting cord group, and regulating the moving route of the connecting cord to be aligned with this finger as a supporting point. SOLUTION: At the time of winding-up action of the connecting cord 3, the connecting cord is wound up by disposing the supporting point 10 near the lowermost point 11 of a U shape. The supporting point 10 exists above the lowermost point 11 of the connecting cord 3 to be wound up. The connecting cord 3 to be wound up is then regulated in the position of the lowermost point 11 by the supporting point 10 and, therefore, the winding-up of the connecting cord through the route near the original U shape is possible. In such a case, the supporting point 10 is placed in the position having a suitable allowance with respect to the position of the lowermost point 11 of the connecting cord 3 found by calculation. This supporting point 10 may be embodied by inserting the insertion and removal finger of an insertion and removal mechanism into the cord layers. |
