Abstract: According to one embodiment, a tablet printing apparatus includes a conveying device, an inkjet printing device, and a control device. The conveying device is configured to convey a tablet. The printing device includes a nozzle array in which a plurality of nozzles are arranged in a direction crossing a conveying path where the tablet is conveyed by the conveying device, and performs printing by ejecting ink from the nozzles to the tablet being conveyed by the conveying device. The control device increases either one of a resolution in the conveying direction of the tablet at the time of performing the printing and a resolution in the array direction of the nozzles at the time of performing the printing higher than the other according to a print density or a print shape on the tablet, and controls the printing device to perform the printing.

Abstract: According to one embodiment, a tablet printing apparatus includes: a conveyer configured to convey a tablet along a line; an applicator head including a plurality of nozzles arranged in a direction crossing the conveyance direction of the tablet conveyed by the conveyer, configured to perform printing on the tablet by ejecting a liquid from the nozzles; and a controller configured to control the ejection of the liquid from the nozzles of the applicator head. The length of an array of the nozzles in a direction perpendicular to the conveyance direction is equal to or longer than the length of the tablet in the direction perpendicular to the conveyance direction. The controller is further configured to control switching of a nozzle used for printing on the tablet among the nozzles by a plurality of sections determined in advance.

Abstract: According to one embodiment, a tablet printing apparatus includes: a first rotator having an inner space; a duct configured to communicate with the inner space of the first rotator; a suction pipe configured to suck inside the duct; a second rotator arranged to face the first rotator across the duct; a conveyor belt wrapped around the first rotator and the second rotator; and a print head that performs printing on a tablet held on the conveyor belt. The conveyor belt includes a plurality of suction holes which communicate with the inner space of the first rotator and that of the duct, and are arranged in the rotation direction of the first rotator. The first rotator and the duct constitutes a suction chamber that applies a suction force to those of the suction holes of the conveyor belt located around the outer periphery of the first rotator and the duct.
