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.

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.

A tablet printing device (1) has a conveying disk (C) that conveys a tablet (3) while sucking and supporting a side surface (5) of the tablet (3) and inkjet heads (4) and (6) capable of applying print processing to the side surface (5) and front and back surfaces (7a) and (7b) of the tablet (3) conveyed by the conveying disk (C). The tablet (3) is transferred from a conveying disk (A) to a conveying disk (B) at a tablet delivery part (8a) and transferred from the conveying disk (B) to the conveying disk (C) at a tablet delivery part (8b). The tablet (3) is sucked to and supported by a suction hole (28) formed in an end surface (Xc) of the conveying disk (C) with a large part of the side surface (5) and the entire front and back surfaces (7a) and (7b) thereof exposed. A tablet provider name or the like is printed on the side surface (5) of the tablet (3) by the inkjet head (4), and an active ingredient name and/or volume are/is printed on the front and back surfaces (7a) and (7b).

A tablet printing device applies print processing to a tablet having an engraved mark display with a recessed groove part. The tablet printing device includes a conveying disk that conveys the tablet while sucking and supporting a side surface of the tablet and an inkjet head capable of applying print processing to the front and back surfaces of the tablet conveyed by the conveying disk. The inkjet head applies print processing to the recessed grooved part of the engraved mark display based on engraving position data obtained by a print surface inspection device. Print processing is performed along the engraved mark display, with the result that the engraved mark display is made clear, significantly improving the visibility thereof.
