Abstract
A paper magazine made up of a small number of parts and capable of rewinding paper pulled out of the case around the roll of paper in the magazine by turning the paper roll. The paper roll is supported on a roll support shaft provided in the magazine case. The roll support shaft includes a core support rod, a pair of cylindrical end members mounted on both ends of the core support rod, and a core mounted on the core support rod between the end members. The paper roll is mounted on the core. When the paper is pulled out of the paper roll, the core is rotated in one direction, so that one of two torsion coil springs tightens to bias the core in the paper rewinding direction. Thus, as soon as the paper is pulled back into the case, the core is turned in the rewinding direction by the one of the coil springs, so that the paper can be smoothly wound around the core.
