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.

Tablet printing apparatus

According to one embodiment, a tablet printing apparatus includes: a conveyor configured to convey tablets sequentially supplied thereto while sucking and holding the tablets by a suction chamber; a print head located to face the conveyor and configured to elect ink to the tablet conveyed by the conveyor to perform printing; and partition wallsand suction pathsthat serve as a suction force adjusting device configured to reduce a suction force applied to the tablet at a conveyance position facing the print head to be lower than a suction force applied to the tablet at conveyance positions in front of and behind the conveyance position.

Tablet printing apparatus and tablet printing method

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.

According to one embodiment, a tablet printing apparatus includes: a conveyor belt configured to convey a tablet; a first suction path configured to suck the tablet to hold the tablet on the conveyor belt and suck the conveyor belt while allowing the conveyor belt to convey the tablet; a second suction path configured as a different path from the first suction path to suck only the conveyor belt while allowing the conveyor belt to convey the tablet; and a printer configured to perform printing on the tablet conveyed by the conveyor belt.
