摘要:
A nozzle plate to be mounted on an ink jet print head includes a plate body on which is formed a plurality of jet aperture portions from which ink is jetted and a water-repellant film formed on this plate body. The diameter of jet aperture portions formed on the plate body and the diameter of water-repellant film apertures formed on the water-repellant film so as to connect with the nozzle apertures are the same diameter R3, so the ink jet flow can be accurately controlled.

The instant invention has an exemplified object to provide an inkjet head and recording device having such an inkjet head with a simpler structure as achieves higher quality of printing inexpensively than the conventional. The pressure-chamber plate of this invention is slit or divided into a plurality of elements.
摘要:
It is an exemplified object of the present invention to provide an inkjet head, its manufacturing method, and a recording device that can form a high-quality image while preventing an ink leakage. To accomplish the object, an indent is provided at a joint surface of a pressure chamber plate with an adhesive.

The ink jet printer includes a pressure chamber plate having a plurality of pressure chambers 20 separated by bulkheads, and a piezoelectric member having drive sections arranged opposite to the pressure chambers via a vibrating plate. The drive sections are separated from each other by parallel extending grooves. The piezoelectric member has inner electrodes 32 embedded therein and exposed to the side surfaces of the drive sections. The exposed portions of the inner electrodes are covered by insulating members, so that no short circuit is caused between the inner electrodes provided in the piezoelectric member.
摘要:
The present invention has an object to provide an inkjet head and a method for manufacturing the inkjet head which not only protects a member at and/or near a surface onto which the nozzle plate is connected (nozzle connection surface), but also shortens the manufacturing time. A protective layer is provided between the nozzle plate and the piezo-electric element, enabling only the protective layer to be polished, protecting the piezo-electric element from being damaged by the polishing when the nozzle connection surface is formed. After the inkjet head is completed, the protective layer prevents ink leakage to the piezo-electric element.

A flash fixing device comprises a first and second flash lamps that emit flashes of light that fix a toner image transferred onto a recording medium and a light emission control unit that controls the light emissions of the first and second flash lamps so that the light flashes emitted from the first flash lamp and the second flash lamp are each irradiated at different timing on each portion on the recording medium.
摘要:
A flash fixing device is disclosed. The flash fixing device has a group of main flash lamps which emit main flash light for fixing a toner image on a recording medium; an auxiliary flash lamp provided at a position corresponding to between a pair of flash lamps of the group of main flash lamps; and a light-emission control unit controlling light-emission of the group of main flash lamps and light-emission of the auxiliary flash lamp by using a predetermined relationship. Also disclosed is an image forming device having the flash fixing device.
摘要:
A fixing device that applies heat energy to a recording medium having a toner image formed thereon to fix the toner image includes a flash fixing part that includes a flash lamp disposed in non-contact with the recording medium and applies heat energy to the toner image formed on the recording medium through discharge luminescence of a gas in the flash lamp, and an air stream spraying part that is disposed in non-contact with the recording medium on a downstream side of the flash fixing part in a transporting direction of the recording medium and sprays an air stream at a prescribed temperature onto a surface of the recording medium.

An optical measuring device measures optical characteristics of an object in a non-contact state. The optical measuring device has a light source that illuminates an object surface, a light receiver that receives a light beam reflected from the object surface, and a light-regulating member that regulates an illuminating light beam radiated onto the object surface and the reflective light beam reflected from the object surface. The light-regulating member has a first light-regulating member that determines at least one of an illuminating region and a reflective region with respect to the object surface, and a second light-regulating member that determines a region where the reflected light beam that is reflected from the object surface and is incident on the light receiver is measured on the object surface.
