Abstract (en)
[origin: EP1839873A1] While stringently avoiding any increase in size of the ink cartridge and reducing the amount of ink that can be stored within the ink reservoir chamber, it is possible to detect that the ink within an ink reservoir chamber (111) has been reduced. There is a light blocking part (42) formed near the edge of the left side of the arm part (41), which is supported such that it can oscillate by a support dais (31) in the fulcrum (41a) near the edge of the right side. The arm part (41) has a branched arm part (44), which is branched and extends downwards in the part between the light blocking part (41) and the fulcrum (41a), and there is a float part (43) at the edge of this. When there is sufficient ink remaining within the ink reservoir chamber (111), the light blocking part (42) will block the light emitted from an light emitting part (1014a) of an optical sensor (1014). When the ink within the ink reservoir chamber (111) is reduced, the light blocking part (42) will move downwards, and it will no longer block the light emitted by the light emitting part (1014a), so that a light receiving part (1014b) will receive this light.
