Patent ID: 8033629

Claim:
A liquid jetting apparatus to which a liquid container is attached, the container containing a liquid and having a first device, the liquid jetting apparatus comprising: a processor that executes a prescribed process in relation to the liquid container; a first line for electrical connection to the first device; a second line for electrical connection to the processor; a controller that, in a first instance, accesses the first device via at least the first line and that, in a second instance, accesses the processor via the second line to have the processor execute the prescribed process; and a connecting module that, in the second instance, electrically sets the first line to a fixed voltage, wherein the first device includes a memory device, wherein the first line is between the connection module and the memory, wherein: the liquid container further includes a second device, the liquid jetting apparatus further includes a third line for electrically connecting the controller and the second device, and the prescribed process includes application of driving voltage to the second device through the third line, wherein the driving voltage is higher than a voltage of a power supply potential of the memory as measured from a ground potential.
