摘要： An object of the present invention is to reduce force acting, when an ink-jet head moves, on a distal end portion of an ink supply pipe connected to a brancher, to thereby prevent damage to the ink supply pipe as much as possible. An ink supplier, which supplies ink to respective ink introduction ports of at least one ink-jet head, has an ink supply pipe connected to an ink cartridge, a brancher to which a distal end portion of the ink supply pipe connected, and branch pipes extending from the brancher to the respective ink introduction ports. The brancher and the branch pipes are adapted to move integrally with the at least on ink-jet head, and in addition the distal end portion of the ink supply pipe and the brancher are connected to each other in a relatively rotatable manner.

摘要： An inkjet printer includes a pair of rollers whose axes of rotation are parallel to each other. An endless conveyor belt is stretched between the pair of rollers. The conveyor belt conveys a print medium in the conveyance direction attendant upon rotations of the pair of rollers. The conveyor belt has, on its outer circumferential surface, an ink receiving groove extending in a direction intersecting the conveyance direction. The depth of the ink receiving groove gradually increases toward the center of the ink receiving groove in the conveyance direction in at least one of regions continuous from front and rear ends of the ink receiving groove in the conveyance direction.

摘要： In order to manufacture an ink-jet head, a head body and a reservoir unit are formed first. Then, UV-cured resin is applied on the lower surface of the reservoir unit. Then, the head body is placed on a plane of a jig so that the plane abuts against the ink discharge surface. Then, the reservoir unit is positioned with respect to the head body and the jig so that an ink reservoir of the reservoir unit and ink flow channels of a flow channel unit are brought into communication and the both ends in the longitudinal direction of a reservoir base plate and the upper surfaces of walls oppose to each other, and the reservoir unit is laminated on upper surface of the flow channel unit via the UV-cured resin. Subsequently, the UV-cured resin is cured in a state in which the lower surface of the reservoir base plate abuts against the upper surfaces of the walls.

摘要： A transfer belt (10) has a two-layer structure consisting of two inner belts (31) formed of metal, such as stainless steel, and an outer belt (32) formed of an elastic material, such as silicone rubber, being spread across the inner belts (31). The inner belts (31) are endless and wound around transfer rollers (12), while the outer belt (32) has its ends which are not joined with each other and form an opening (20) therebetween. Distortion of the outer belt (32) due to stress is designed to be suppressed by using a reinforcing member around the opening (20).

摘要： Rollers between which an endless belt is wound have a pair of first grooves looping around a rotational axis of each roller. A pair of second grooves is formed in an upper face of a support plate that supports an inner face of the endless belt, these second grooves extending along an entire length of the support plate in a feeding direction of the printing sheet. Each of the first grooves and the second grooves are disposed so as to be in the same straight line. First ink absorbers are provided that absorb ink within the first grooves. Second ink absorbers are provided that absorb ink within the second grooves. Protruding rails are formed on the inner face of the endless belt and fit into the first grooves and the second grooves. These first and second grooves prevent feeding accuracy of printing sheets from deteriorating.
