Abstract
A paper magazine which can feed paper from a paper roll at high speed with high accuracy. Provided between a drive shaft and a paper feed roller are a normal rotation transmission for transmitting only the rotation of the drive shaft in the normal direction to the feed roller and a reverse rotation transmission for transmitting only the rotation of the drive shaft in the reverse direction to the feed roller. A rotation transmission mechanism is provided between the drive shaft and a core for nonrotatably supporting a paper roll to transmit both the normal and reverse rotations of the drive shaft to the core. To feed paper from the paper roll, the feed roller and the core are rotated in the paper feed direction, while controlling the rotating speed of the core so that the peripheral speed of the feed roller is higher than the peripheral speed of the paper roll when its diameter is maximum to apply suitable tension to the paper being fed. To rewind paper on the paper roll, the feed roller and the core are rotated in the paper rewinding direction, while controlling the rotating speed of the core so that the peripheral speed of the feed roller is lower than the peripheral speed of the paper roll when its diameter is minimum to apply suitable tension to the paper being rewound.
