Abstract
An ink jet printhead module including multiple chip control circuits is provided. The ink jet printhead module is capable of receiving multiple address signals and multiple chip selection signals from a printhead drive unit of the printing apparatus. Each of the chip control circuits is capable of receiving the address signals and a corresponding one of the chip selection signals. Each of the chip control circuits includes multiple switching circuits and an ink jetting circuit set. Each of the switching circuits is capable of receiving a corresponding one of the address signals and the corresponding one of the chip selection signals and outputting a switching signal. The ink jetting circuit set includes multiple ink jetting circuits. Each of the ink jetting circuits is capable of receiving the switching signal from the corresponding switching circuit and determining whether or not to jet out ink based on the received switching signal.
