发明名称 Droplet discharging head and image forming apparatus
摘要 A droplet discharging head includes: a nozzle substrate that includes a nozzle opening to discharge a droplet therethrough; a liquid chamber substrate that includes liquid pressure chambers communicating with the nozzle openings; a vibration plate arranged to face the nozzle substrate with the liquid chamber substrate interposed therebetween; piezoelectric elements that are provided to face the liquid pressure chambers with the vibration plate interposed therebetween and are arranged in a predetermined direction; a driving element provided, in a flip-chip implementation, on a flow path substrate that includes the nozzle substrate, the liquid chamber substrate, the vibration plate, and the piezoelectric elements; and a first reinforcing wire that is disposed to at least one of the flow path substrate and the driving element, has a band shape extending in a direction along a row of the piezoelectric elements, and is connected to a common electrode shared by the piezoelectric elements.

主权项 1. A droplet discharging head comprising: a nozzle substrate that includes a nozzle opening configured to discharge a droplet therethrough; a liquid chamber substrate that includes a plurality of liquid pressure chambers communicating respectively with the nozzle openings; a vibration plate arranged to face the nozzle substrate with the liquid chamber substrate interposed therebetween; a plurality of piezoelectric elements that are provided to respectively face the liquid pressure chambers with the vibration plate interposed therebetween and are arranged in a predetermined direction; a driving element provided, in a flip-chip implementation, on a flow path substrate that includes the nozzle substrate, the liquid chamber substrate, the vibration plate, and the piezoelectric elements such that the driving element is bonded to each of the piezoelectric elements; and a first reinforcing wire that is disposed to at least one of the flow path substrate and the driving element,that has a band shape extending in a direction along a row of the piezoelectric elements, andthat is connected to a common electrode shared by the piezoelectric elements through at least one connecting position.
