Abstract:
1. An liquid jetting apparatus, comprising: a liquid jetting head, provided with nozzle orifices, pressure chambers each commutated with one of the nozzle orifices, and pressure generating elements each associated with one of the pressure chambers to vary pressure of ink contained therein; a drive circuit, which generates a drive signal for driving at least one of the pressure generating elements; and a flexible flat cable, which connects the drive circuit and the liquid jetting head to supply the drive signal to at least one of the pressure generating elements, the flat cable including a plurality of layers, each provided with a plurality of first conductive patterns each connecting a positive pole of the drive circuit and a positive pole of one of the pressure generating elements, and a plurality of second conductive patterns each connecting a negative pole of the drive circuit and a negative pole of one of the pressure generating elements, wherein: at least one of the first conductive patterns provided in one of the layers faces one of the first conductive patterns provided in another one of the layers; and at least one of the second conductive patterns provided in one of the layers faces one of the second conductive patterns provided in another one of the layers, wherein each of the plurality of layers is formed of a single layer, which includes the first conductive patterns and the second conductive patterns.
