PURPOSE:To prevent roll paper from slipping off or being smudged on a floor, by installing a device, which makes the roll paper easily detachable and vice versa while its supporting effort in an axial direction larger, and lays down the roll paper on the floor in a state of being stabilized, in a setting device for a supporting shaft of the roll paper. CONSTITUTION:Roll paper 20 is attached to a supporting shaft 10 with a core material 21 nippingly held by a core stopper 13. At this time, unevenness in an axial direction of the core material 21 is absorbed correctively by a spring 14 energizing the core stopper 13 whereby the core material 21 is firmly supported by dint of reaction force of the spring 14. In addition, in time of removal, it will do to merely rotate a latch 16 in defiance of the force of a spring 17 and make a cylinder body 11 slide along the supporting shaft 10 immediately after removing an engaging part 16a from a groove 19. Since a polygonal hole 11a of the cylinder body 11 is well fitted in the polygonal supporting shaft 10, each phase of flanges 12 at both sides is always congruent and at the same time each flange 12 becomes larger than the maximum diameter of the roll paper 20. |
