摘要： Ejection nozzles (152a-152g) are located in a nozzle surface (153) of an ejection head (150). A distance (H: Ha-Hg) between each of the ejection nozzles (152a-152g) and a printing object (109) is obtained and compared with a permissible distance (H0) which is determined by the required level of print quality. The ejection nozzles (152a-152d) whose distances (H) from the printing object (109) are not more than the permissible distance (H0) are enabled for ink ejection, while the ejection nozzles (152e-152g) whose distances (H) are greater than the permissible distance (H0) are disabled for ink ejection. The surface of a printing object (228) is divided into a plurality of target areas (205), each of which is then approximated by a projective plane (206). Then, image data about a projected image (208) which is obtained by orthogonal projection of a print image (207) onto the projective planes (206), is obtained from print image data about an image to be printed on the surface of the printing object (228). According to the projected image data obtained, printing is performed on the target area (205) while moving a ink-jet printhead (210) in parallel with the projective planes (206). This inhibits image degradation during printing on a three-dimensional printing object and also facilitates control of the inclination and position of the ejection head relative to the printing object, thereby permitting high-speed printing.

摘要： A running and working robot for performing a prescribed work while it runs includes a body with a running unit, and a working unit for working, and the body is coupled to the working unit by means of a coupling member with a buffer member. As a result, even when an excessive force or shock is given to the coupling portion between the working unit and the body, damage to the coupling portion can be prevented.

摘要： An apparatus of spreading a fluid on the floor includes four rectangular application rotating bodies partially overlapping each other, and four nozzles supplying the fluid provided in rotation areas of the respective application rotating bodies. The rotation position of the application rotating body is detected by a light shielding plate and a photosensor. A control portion controls each component so that the fluid is applied onto the floor from a tank through the nozzle by a pump when the application rotating body is not directly under the nozzle. As a result, the apparatus of spreading a fluid on the floor capable of optimally controlling the quantity of the fluid to be applied according to the application condition can be provided.
