Description

また、前述の説明では、リターン配管６１の入口Ｈ１を、搬送ベルト２１ａ（３１ａ）の上面において第２の撮像装置２５（３５）が設けられた位置より錠剤Ｔの搬送方向の下流側に位置させたが、第１の撮像装置２３（３３）と印刷ヘッド装置２４（３４）との間、あるいは、印刷ヘッド装置２４（３４）と第２の撮像装置２５（３５）との間に位置させるようにしてもよい。つまり、リターン装置２６（３６）は、錠剤Ｔの姿勢と位置のどちらか一方又は両方を検出する撮像装置２３（３３）が設けられた位置に対し、錠剤Ｔの搬送方向の下流側に位置する未印刷錠剤を、錠剤Ｔの搬送方向の上流側に戻すものであればよい。なお、撮像装置２５（３５）は検出装置を構成する。

Further, in the above description, the inlet H1 of the return pipe 61 is positioned on the upper surface of the conveyor belt 21a (31a) downstream of the position where the second imaging device 25 (35) is provided in the tablet T conveyance direction. However, it should be positioned between the first imaging device 23 (33) and the print head device 24 (34) , or between the print head device 24 (34) and the second imaging device 25 (35). can be In other words, the return device 26 (36) is positioned downstream in the tablet T conveying direction with respect to the position where the imaging device 23 (33) that detects one or both of the posture and position of the tablet T is provided. It is sufficient that the unprinted tablet is returned to the upstream side in the tablet T conveying direction. Note that the imaging device 25 (35) constitutes a detection device.
