Abstract
A paper magazine is capable of feeding and rewinding a web of paper automatically without forming any indentation in or causing meandering of the web of paper. A pair of press rollers and a paper detection roller are provided along a feed path extending from the core of a paper roll in a paper magazine case to a paper outlet. A cam plate and an engaging roller control the movement of the press rollers toward and away from each other according to the position of the paper detection roller. The transmission of driving force to the core of the paper roll and the press rollers is changed over according to the position of the paper detection roller. The press rollers are pressed against the paper only when feeding and rewinding the paper.
