Kind Code:

A1

Abstract:

[Problem] To provide a tablet printing device that can prevent ink at each distal end of nozzles of an inkjet type printing mechanism from drying out in a situation in which a tablet does not arrive at a printing position. [Solution] A tablet printing device has: a conveyance mechanism 17 that moves a conveyance belt 171 to convey sequentially supplied tablets; an inkjet type printing mechanism that performs printing on a tablet at a printing position; a suction mechanism 174a that sucks air to cause the tablet to adhere to a surface of the conveyance belt within a predetermined range including at least the printing position; a determination means (S15) that determines whether or not a tablet arrives at the printing position; and a head retraction means (32, S21) that retracts an inkjet head 31 so that the distal end of each nozzle of the inkjet type printing mechanism moves away from the surface of the conveyance belt when it is determined that a tablet does not arrive at the printing position.
