PROBLEM TO BE SOLVED: To improve productivity by shortening a print stop time accompanying maintenance of a coating head.SOLUTION: A tablet printing device 1 includes a conveying device 3 which conveys tablets T in line, a coating head 5A which has a plurality of nozzles arrayed in a direction intersecting a conveying direction of the conveyed tablets T and prints by discharging a liquid from the nozzles, and a moving device which moves the coating head 5A in a direction orthogonal to the conveying direction of the tablets T. A length in a direction orthogonal to a conveying direction of the nozzle array with the plurality of nozzles arranged is longer than the direction orthogonal to the conveying direction of the tablets T. The plurality of nozzles are divided in either one of a plurality of predetermined sections. A control device 9 switches the nozzle used for printing of the tablet T between the plurality of sections by moving the coating head 5A in the direction intersecting the conveying direction by the moving device between start of printing and execution of maintenance of the coating head 5A.SELECTED DRAWING: Figure 17COPYRIGHT: (C)2019,JPO&INPIT【課題】塗布ヘッドのメンテナンスに伴う印刷の停止時間を短縮し、生産性を向上させる。【解決手段】錠剤印刷装置１は、錠剤Ｔを列状に搬送する搬送装置３と、搬送される錠剤Ｔの搬送方向と交差する方向に配列された複数のノズルを有し、ノズルから液体を吐出させて印刷を行なう塗布ヘッド５Ａと、塗布ヘッド５Ａを錠剤Ｔの搬送方向と直交する方向に移動させる移動装置とを備え、複数のノズルが並ぶノズル列における搬送方向と直交する方向の長さは、錠剤Ｔにおける搬送方向と直交する方向の長さ以上で、複数のノズルは予め定められた複数の区画のいずれか一つに区分けされ、制御装置９は、印刷が開始後塗布ヘッド５Ａのメンテナンス実行までの間に、移動装置により塗布ヘッド５Ａを搬送方向と交差する方向に移動させることにより錠剤Ｔの印刷に用いるノズルを複数の区画間で切り替える。【選択図】図１７
