<P>PROBLEM TO BE SOLVED: To provide an inkjet head module having low current consumption capable of suppressing influence of noise, an inkjet head control circuit, a method of transferring data and a liquid droplet ejecting device. <P>SOLUTION: This inkjet head control circuit has a latch circuit 111 for holding a first data row for ejection of a liquid droplet and a second data row succeeding the first data row, respectively, and a data judgment section 112 for calculating a condition transition data row based on the held first and second data rows. The data judgment section 112 outputs the condition transition data row (Low) of a first value when the first data row and the second data row are the same and outputs the condition transition data row (High) of a second value when the first data row and the second data row are different from each other. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
