Abstract
In a liquid droplet discharge head, a liquid repellent layer is continuously formed from a liquid droplet discharge surface to a middle position in a thickness direction of an end surface of a nozzle plate.
Claims13
A liquid droplet discharge device comprising:
- a liquid droplet discharge head in which a liquid repellent layer is coated on a liquid droplet discharge surface of a nozzle plate;
- a fixing plate that fixes the liquid droplet discharge head to a head supporter;
- and
- a wiping member that wipes the liquid droplet discharge surface by a relative movement with the liquid droplet discharge head,
- wherein the liquid repellent layer is continuously coated to an end surface of the nozzle plate over a boundary between the liquid droplet discharge surface and the end surface, and
- the fixing plate does not overlap the liquid droplet discharge surface and fixes the liquid droplet discharge head to the head supporter, at least in an end portion of the nozzle plate located at an initial point side of wiping using the wiping member.
A method of manufacturing a liquid droplet discharge device that has a liquid droplet discharge head in which a liquid repellent layer is coated on a liquid droplet discharge surface of a nozzle plate, a fixing plate that fixes the liquid droplet discharge head to a head supporter, and a wiping member that wipes the liquid droplet discharge surface by a relative movement with the liquid droplet discharge head, the method comprising:
- forming nozzle holes on the substrate;
- forming a plurality of grooves on one main surface of the substrate;
- coating the liquid repellent layer on the main surface;
- and
- cutting the substrate along the plurality of grooves to obtain individual pieces of a plurality of nozzle plates.
A liquid droplet discharge device that has a nozzle plate in which a liquid repellent layer is formed on a liquid droplet discharge surface,
- wherein the liquid repellent layer is also formed in an end portion of the nozzle plate, and the liquid repellent layer formed on the liquid droplet discharge surface continues with the liquid repellent layer formed in the end portion.
