ABSTRACT:
An apparatus for detecting the remaining amount of rolled paper, the diameter of which decreases as it is unrolled, comprises a detection lever which is swingable in a manner such that its free end is always in contact with the decreasing outer diameter of the roller paper. The detection lever includes a magnet piece which actuates a magnetism sensor for actuating an alarm device indicating the time for exchanging the roller paper when the diameter of the paper roll decreases to a predetermined diameter.
