Abstract
A liquid jet recording head comprises a recording head element having a discharge port for discharging liquid to form flying droplets and an energy generating element for generating an energy to form the droplets, an ink tank for storing the liquid to be supplied into the recording head element, and wirings electrically connected to the energy generating element. Th wirings are embedded in a member constituting the ink tank, and the recording head element is arranged on a wall of the ink tank.
Claims15
A liquid jet recording head comprising:
- a recording element having a discharge port for discharging liquid to form flying droplets, an energy generating element for generating energy to form the droplets and a first terminal electrically connected to said energy generating element for supplying an electrical signal to said energy generating element;
- an ink tank for storing liquid to be supplied to said recording element, wherein said recording element is arranged on a wall of said ink tank and said ink tank includes a second terminal electrically connected to said first terminal;
- wiring electrically connected to said second terminal to supply an electrical signal to said energy generating element through said terminals, at least a portion of said wiring being embedded in said ink tank;
- and
- recording element positioning means arranged on said ink tank to position said recording element relative to said ink tank.
