Abstract:
A connection cable electrically connects a head unit and a head unit control circuit. The head unit includes: an ejector, a determination circuit, and an ejection limit circuit. The ejector includes a displaceable piezoelectric element for controlling the liquid ejection. The piezoelectric element is displaced by changing a drive signal potential. The determination circuit determines whether the piezoelectric element has a predetermined electrical storage capability. The ejection limit circuit stops the drive signal to limit the ejection of the liquid based on the determination. The connection cable includes: a first connection supplying a determination instruction signal from the head unit control circuit to the head unit; a second connection supplying the drive signal from the head unit control circuit to the head unit; and a third connection between the first and second connections with a smaller potential change width than the second connection when the ejector ejects the liquid.

Claim (Index 1):
A connection cable that electrically connects a head unit and a head unit control circuit, the head unit including:\n an ejecting section that includes a piezoelectric element, and can eject a liquid corresponding to displacement of the piezoelectric element, the piezoelectric element being displaced corresponding to a change in potential of a drive signal when the drive signal has been supplied to the piezoelectric element; a determination circuit that determines whether or not the piezoelectric element has a predetermined electrical storage capability; and an ejection limit circuit that stops the supply of the drive signal to the piezoelectric element and limits the ejection of the liquid from the ejecting section when a result of the determination is negative, the head unit control circuit controlling the head unit, and being provided outside the head unit, the connection cable comprising: a first connection line that supplies an instruction signal to the head unit, the instruction signal being generated by the head unit control circuit, and instructing the head unit to execute the determination; a second connection line that supplies the drive signal to the head unit, the drive signal being generated by the head unit control circuit; and a third connection line that is provided between the first connection line and the second connection line, the third connection line being smaller in potential change width than the second connection line when the ejecting section ejects the liquid.
