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: [Problem to be Solved]To provide a tablet printing apparatus that can prevent drying of ink on the tip end of each nozzle of an inkjet printing mechanism, when a tablet does not arrive at a print position.[Solution]A tablet printing apparatus includes: conveyor mechanism 17 that conveys sequentially fed tablets by moving a conveyor belt 171; an inkjet printing mechanism that performs printing on a tablet in a print position; a suction mechanism 174a that holds a tablet on the surface of the conveyor belt in a predetermined area including at least the print position by sucking in air; determination means (S15) that determines whether a tablet arrives at the print position; and head retreat means (32, S21) that retreats an inkjet head 31 such that a tip end part of each of the nozzles of the inkjet printing mechanism goes away from the surface of the conveyor belt, when it is determined that a tablet does not arrive at the print position.
