Abstract: According to one embodiment, a tablet printing apparatus includes a conveyor, an inkjet print head, and a controller. The conveyor is configured to convey a tablet having an outer shape that does not determine the printing direction of a print pattern to be printed thereon. The print head includes a plurality of nozzles each configured to eject a liquid to print the print pattern on the tablet being conveyed. The controller is configured to control the print head to perform printing on the tablet being conveyed such that the printing direction of the print pattern is changed at predetermined intervals at least between a first direction which is parallel to or crosses the conveying direction of the tablet, and a second direction which crosses the conveying direction, and in which more nozzles are used for printing than in the first direction.

Abstract: A tablet printing apparatus and a tablet manufacturing method are provided which are capable of distinguishing and collecting a preceding tablet and a following tablet from each other when two or more tablets in contact with each other are carried. A tablet printing apparatus includes a carrying device 20 carrying tablets Tb, a sensor 30 detecting the tablet Tb being carried by the carrying device 20, a printing unit 50 performing, when the status changes from the status in which the sensor 30 the tablet Tb is not detected to the status in which the tablet Tb is detected, printing on the tablet Tb that has changed the status, and a collecting unit R distinguishing and collecting, when the time length at which the sensor 30 is detecting the tablet Tb is longer than the predetermined setting value because two or more tablets Tb in contact with each other are carried, the preceding tablet Tb and the following tablet Tb following thereto among two or more tablets Tb.
