Abstract: According to one embodiment, a tablet printing apparatus includes: a conveyor; an inkjet head configured to eject ink from a nozzle to a tablet conveyed by the conveyor to perform printing; an ink tank configured to contain the ink to be supplied to the inkjet head; a moving device configured to change the height of the ink tank; and a control unit configured to control the moving device. The control unit controls the moving device to change the height of the ink tank based on a use amount of the ink figured out in advance to maintain a head difference between the height of the liquid level of the ink in the ink tank and the height of a nozzle forming surface, where the nozzle is formed in the inkjet head, at a predetermined value.

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.
