Abstract

PURPOSE:To eliminate the need for a plurality of detectors and the waste that the elimination of a switch due to the ink replacement, by a method wherein the states that a cassette is unloaded and that a remaining ink quantity is small are detected by one and the same detector due to the motion of the rear end of an actuator to a detecting position. CONSTITUTION:When a cassette 6 is inserted to a detector on the device side from a direction of A, an abutting plate 19 is shifted in a direction of C by the cassette 6, whereby a spring bearing 20 is traveled to a position 20', and a detection piece 16 of a bag 11 is engaged with a top end 17a of an actuator 17. In the condition that the cassette is unloaded a detection position 21 is open, but with the cassette inserted it is closed by a rear end 17b of the actuator 17. When the reduction of the quantity of remaining ink leads the actuator 17 to travel to a position shown by a two-dot chain line, the rear end 17b passes through the detection position 21 and then the detection position 21 is opened. In this manner, the state that the cassette is unloaded on the main body side and the state that a remaining ink is reduced to a small quantity after the insertion of the cassette are detected by the same detector.
