ABSTRACT:
An apparatus for detecting the amount of paper remaining in a paper cassette of a printer is provided. The apparatus includes a spring elastically biasing the base plate upward at an opposite side from a hinged side, a rack gear installed on the bottom surface of the base plate extending downward, a pinion gear rotating interlockingly with the vertically movement of the rack gear, a variable resistor providing variable resistance values through two fixed terminals according to the rotation positions of the pinion gear, a voltage signal generator connected to the terminals, for generating voltage signals corresponding to the resistance value of the terminals, and a paper amount determining unit for reading the voltage signal to determine the amount of papers in the base plate, and outputting information on the amount of paper remaining. Thus, information on the amount of remaining paper can be sent to a remote user away from the printer display through a communications network connected thereto.
