Abstract: According to one embodiment, a tablet printing apparatus includes a conveyor configured to convey tablets sequentially supplied while sucking and holding the tablets; a print head arranged to face the conveyor to perform printing on each of the tablets being conveyed; a detector arranged upstream of the print head to detect the posture of each of the tablets; and a print condition tester arranged downstream of the print head to check print condition on each of the tablets. Suction force applied to the tablets is reduced at least in an area from a detection position to a print condition check position than in other area.

Abstract: 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. 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.

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.
