摘要： To cure a layer of curable material for building more uniformly and appropriately at the time of building an object. A building apparatus that builds an object using a curable material that is cured by being irradiated with an ultraviolet ray, the building apparatus including: an ink-jet head serving as an ejection head that ejects a curable material for building; a UV light source that emits the ultraviolet ray to the curable material ejected from the ink-jet head; and a light source driver that supplies electric power for driving the UV light source. The UV light source is a UV LED, and the light source driver supplies electric power that varies in a pulse-like form to the UV light source to drive the UV light source using a pulse driving scheme.

摘要： An ink supplying device is provided and supplies a functional ink to a droplet ejecting portion, including: a tube body through which the functional ink passes; a degasser that removes a dissolved gas from the functional ink; a first supply path in which the degasser is fitted to the tube body; a second supply path in which the degasser is not fitted to the tube body; and a controller that switches a supply path of the functional ink to the second supply path when a viscosity of the functional ink is higher than or equal to a predetermined value, and switches the supply path to the first supply path when the viscosity of the functional ink is lower than the predetermined value. The first supply path and the second supply path are coupled by an upstream side coupling portion and a downstream side coupling portion.

摘要： An inkjet printing apparatus includes an inkjet head that moves in a main scanning direction at the time of printing; a filter chamber provided on a path for supplying ink to a nozzle hole (nozzle) in the inkjet head; and a spherical body placed on a head filter in the filter chamber. The spherical body has a diameter φ larger than the mesh of the head filter. The spherical body is disposed on the head filter so as to be rollable by the movement of the inkjet head.

摘要： A photographing apparatus for photogrammetry continuously photographs a target object performing a series of motions by synchronizing a plurality of photographing devices provided at a plurality of different viewpoints. The plurality of photographing devices include the plurality of image-capturing units that photograph the target object. Each of the plurality of photographing devices includes the plurality of primary storages each storing each image data of the target object photographed in synchronization by the plurality of image-capturing units, and the plurality of signal output units each outputting a completion signal for each of the image data when storage of each of the image data in a preceding motion of the target object into the plurality of primary storages is completed. The plurality of photographing devices perform photographing in the subsequent motion of the target object based on the completion signal of the signal output unit.
