Paper box for recording paper scroll, and recording paper scroll

Abstract

A roll(12) of a recording paper(11) is rotatably contained in a paper magazine(2). The magazine(2) is provided with a mouth(8) through which the recording paper(11) is drawn out and fed to a printer. A leading edge of the recording paper(11) is adapted to come into contact with an outer periphery of the roll(12) by a contacting device(51). The remainder of the roll(12) is indicated by an indicating device(80). The mouth(8) of the magazine(2) is opened and closed with a shutter unit(9). The inside of the magazine(2) tightly closed with the shutter unit(9) is kept at constant humidity by a humidity conditioning paper(90). On the other hand, the roll(12) is caught between a pair of flanges(133, 134). One of the flanges is biased by plate springs(130a, 130b, 130c) toward the other of the flanges so that the roll(12) is held in the magazine without looseness.
