Abstract

PURPOSE: To enable the quantity of the paper held in a paper holding means to be directly detected and indicated.
CONSTITUTION: In case where paper 13 is contained in a large quantity in the cassette body 11, a paper stand 12 is positioned at the lowest part. In consequence, a contact piece 16 to interlock with the paper stand 12 is also positioned at the lowest part. In a other word, a variable resistor 18 moves in the direction of arrow (a), and its value of resistance becomes the maximum. As the quantity of paper 13 decreases in parallel with advance of duplication, the paper stand 12 gradually goes up subsequently. Accordingly, variable resistor 18 moves in the direction of the arrow and it value gradually decreases. And display elements 91W95 come on in response to said value of resistance, so that the quantity of the paper can be indicated.
