    • PROBLEM TO BE SOLVED: To enable an operator to easily set a paper roll on a support shaft by arranging a plurality of support members for slidingly supporting the inner periphery of a hollow core tube rolling in the inserting/taking-out direction in inserting the hollow core tube into the support shaft on a support shaft surface. SOLUTION: A cap 10 where support members 12 for guiding an inner peripheral surface of a hollow core tube wound with a roll-shaped medicine bag to a support shaft are arranged at a 90 deg. interval in the peripheral direction and guide bearings 13 for guiding an inner peripheral surface of the hollow core tube supported by the support members 12 further to the inmost part of the support shaft are arranged at a 90 deg. interval in the surface peripheral direction of a hollow shaft 11 on a surface of the hollow shaft 11, is installed on the hollow shaft. The guide bearings 13 support a moving load in the shaft inserting/taking-out direction of the hollow core tube. The support members 12 can move on the inner peripheral surface of the hollow core tube without being limited by the load direction, and even if the hollow core tube slightly bends to the support shaft, the support members 12 guide the inner periphery of the hollow core tube, and becomes parallel to the support shaft when insertion of the hollow core tube advances, and stop by a collar 14. A rotation preventive pin is arranged on the collar 14 for preventing a rotational directional slip of the hollow core tube.
