Abstract
A jetting head is provided with a plurality of rows of nozzles, a plurality of pressure generating elements associated with the respective nozzles to generate pressure to eject jetted objects from the nozzles. A head driver generates a drive signal and a ground signal to be supplied to each of the pressure generating elements. A plurality of flexible flat cables include signal lines connecting the head driver and the jetting head. The flexible flat cables are arranged such that a first signal line for supplying the drive signal to one of the nozzle rows is provided in one of the flat cables and a second signal line for supplying the ground signal to the one of the nozzle rows opposes to the first signal line while being provided in another one of the flat cables.
