<p>PURPOSE:To make it possible to set and hold a rolled paper on a shaft at a suitable position, by providing such an arrangement that retractable pins set on the shaft at the positions corresponding to the sizes of rolled papers are fitted into the pin receiving grooves which are formed in both end faces of a paper sleeve for the rolled paper. CONSTITUTION:A shaft 12 is inserted into a paper sleeve 11 for a rolled paper 10 having a predetermined size while pins 4 set on the shaft 12 at the positions corresponding to the size of the rolled paper 10 and urged by springs 15 are depressed overcoming the spring 15, and then the pins 14 are aligned with the pin receiving grooves 16 formed in both end faces of the paper sleeve 11 to allow the pins 14 to project by the recovering force of the springs 15 so that the pins 14 is fitted into the pin receiving grooves 16, theeby the rolled paper 11 is positioned and held on the shaft 12 at a predetermined position. Upon extraction of the rolled paper 10 from the shaft 12 the pins 14 are depressed overcoming the spring 15 by fingers stucked into the gaps between the pins 14 and the pin receiving grooves 16 while the rolled paper 10 is extracted from the shaft 12.</p> |
