Abstract
An apparatus for detecting the remaining sheets of paper supplied in a facsimile, is disclosed including a supplier for supplying paper; a generator for generating a signal corresponding to the mounting of the supplier and the number of sheets of paper supplied; a detector for detecting the signal of the generator; a calculator for calculating the number of sheets of remaining paper according to a detection signal; and a display for displaying the number of sheets of remaining paper calculated in the calculator.
Claims17
An apparatus for detecting the remaining sheets of paper supplied in a facsimile, said apparatus comprising:
- means for supplying paper;
- means for generating a signal corresponding to the mounting of said supply means and the number of sheets of paper supplied, wherein said generating means comprises a plurality of magnets for generating signals of different polarities;
- means for detecting the signal of said generating means;
- means for calculating the number of sheets of remaining paper according to a detection signal, wherein the calculating means calculates the volume, thickness and number of remaining sheets of paper supplied according to a variation amount of a linear voltage of said generating means;
- and
- means for displaying the number of sheets of remaining paper calculated in said calculating means.
