Abstract
A nozzle plate holding device having a holding section which holds a nozzle plate arranged with a plurality of nozzles, and the nozzle plate holding device being used for bonding the nozzle plate, while the holding section holds the nozzle plate, onto a head chip arranged with a plurality of channels, wherein the holding section is configured to be capable of causing a distortion deformation of the nozzle plate in a direction that is parallel to a surface of the nozzle plate and crosses a length direction of the nozzle plate.
Claims3
A manufacturing method of an ink jet head for holding a nozzle plate arranged with a plurality of nozzles by a holding device, and bonding the nozzle plate held by the holding device onto a head chip arranged with a plurality of channels such that positions of the plurality of nozzles and positions of the plurality of channels coincide with each other, the method comprising the steps of:
- holding the nozzle plate with the holding device;
- correcting a deformation of the nozzle plate, held by the holding device, by causing a distortion deformation of the nozzle plate in a direction that is parallel to a surface of the nozzle plate and crosses a length direction of the nozzle plate;
- and
- bonding the nozzle plate corrected of the deformation onto the head chip.
