Paper size detecting circuit

The three paper size switches (SW1, SW2, SW3) are activated according to the positioning of the
paper size dial on the paper cassette. An analog signal is generated by the combination of the paper
size switches, which are put in comparison with the voltage/paper size table referenced by the
paper size detecting circuit. The paper size is detected.
