SOLUTION: A locking groove 15 which enables a locking tool 11 to be inserted to a takeup roll 2 from its one end about the longitudinal direction to the other end and which engages the locking tool 11 so that it can not be drawn out in the direction intersecting the longitudinal direction, is provided in the range from the first named end of the takeup roll 2 to a point on the way to the other end, and a store/extract hole 8 is formed in the range from one end of the accommodation case 1 about its longitudinal/direction to a point on the way to the other end so that a saddle cover 3 coupled with the takeup roll 2 can be inserted in the longitudinal direction to the store/extract hole 8 from the first named end of the case 1 when the takeup roll 2 is to be accommodated in the case 1 from the opening of the case 1, wherein the store/extract hole 8 is in communication to the opening of the case 1. |
