Patent ID: 7448712

Claim:
A signaling module mountable on a liquid container for supplying liquid to a recording/printing apparatus, the signaling module comprising: a signal-connecting portion capable of receiving an input signal from the recording/printing apparatus; a light-emitting unit capable of emitting light; a light-emission driving unit that drives the light-emitting unit; a control circuit that controls the driving of the light-emitting unit by the light-emission driving unit on the basis of the input signal transmitted from the signal-connecting portion; an information storage portion that stores information regarding the liquid container; wherein the control circuit arranges for the driving of the light-emitting unit by the light-emission driving unit to occur in a period different from the period in which the input signal is transmitted from the signal-connecting portion, wherein the control circuit performs at least one of a driving process or an information process on the basis of the input signal transmitted from the signal-connecting portion, the control circuit controlling the driving of the light-emitting unit by the light-emission driving unit in the driving process and controlling at least one of an operation of writing information to the information storage portion and an operation of reading information from the information storage portion in the information process, and wherein the control circuit performs the driving process in a signal input/output inactive period provided between periods in which signals are input and output from the signal-connecting portion.
