Liquid consumption apparatus and liquid consumption amount control method

摘要

The invention provides a liquid consumption apparatus to which a liquid container for containing liquid is attachable. The liquid consumption apparatus according to an embodiment of the invention includes: a liquid consumption unit that consumes the liquid contained in the liquid container; a counting unit that counts the amount of the liquid consumed by the liquid consumption unit as a liquid consumption amount; a liquid amount memory unit that memorizes the liquid consumption amount counted by the counting unit one after another; a reception unit that receives a detection signal indicating that the amount of the liquid contained in the liquid container is not more than a predetermined amount; a detection-time liquid amount memory unit that memorizes the liquid consumption amount at the time of reception of the detection signal as a detection-time liquid consumption amount, that is, a liquid consumption amount at the time of detection; and a judgment unit that judges that the liquid container is empty when the amount of difference between the liquid consumption amount memorized in the liquid amount memory unit and the detection-time liquid consumption amount is not more than a judgment liquid amount.
