Device for detecting remaining quantity of rolled papers |
摘要 |
A device for detecting remaining quantity of rolled papers has housing having a bottom for supporting a rolled paper. Optical detectors are provided for detecting a peripheral position of the rolled paper supported on the bottom when the peripheral position approaches an inner end of the paper and for generating an output signal. A positioning lever is provided for positioning the detectors at a position dependent on a radius of a core of the rolled paper. A control circuit responds to the output signal for informing that the rolled paper reaches the inner end.
