Problem to be solved: to easily attach or remove the abutment member to the rotary shaft and to add the bulk tablet repellency function.An engaging shaft 70 having an engaging part 71 is inserted into the drive shaft fitting hole 23a of the rotary shaft 23 in an axial movement state.The mooring member 60 is mounted on the inner bottom surface of the container part 21, and the retaining shaft 70 is made to move around the retaining shaft 70 to a large number of mooring recesses 61.In the cassette free state, the engaging shaft 70 is urged by the biasing member 72 of the bottom of the drive shaft fitting hole 23a to engage the locking portion 71 with the mooring recess 61, while the locking portion 70 is engaged with the mooring recess 61In the case where the cassette is mounted, the biasing force is suppressed and the locking portion 71 is detached from the mooring recess 61.AndThe thrust member 62 of the Yamagata is provided on the outer peripheral side of the mooring recesses 61 andAn overfitting preventing means is provided between the lower end annular surface 22da of the cylindrical portion 22d and the upper end annular surface 23bc of the large-diameter portion 23bb of the rotary shaft 23 in the fitting state in which the small diameter portion 23ba of the rotary shaft 23 is fitted into the cylindrical portion 22d of the alignment plate 22, and the upper surface ring face 23bc of the large diameter portion 23bb of the rotary shaft .Diagram【課題】回転軸への当接部材の着脱や取替にて簡便に塊状錠剤ほぐし機能を付加する。【解決手段】係止部７１を持った係止用軸体７０を回転軸２３の駆動軸嵌入孔２３ａに軸方向移動可能状態で挿入し、係留部材６０を容器部２１の内底面に装備して多数の係留用凹凸６１に係止用軸体７０を一周させ、カセット自由状態では係止用軸体７０を駆動軸嵌入孔２３ａの底の付勢部材７２にて付勢して係止部７１を係留用凹凸６１に係合させる一方、カセット装着状態では付勢を抑えて係止部７１を係留用凹凸６１から離脱させるようにしたうえで、更に、山形の衝上部材６２を係留用凹凸６１の外周側に設けるとともに、回転軸２３の小径部分２３ｂａを整列盤２２の筒部２２ｄに嵌入した嵌合状態において筒部２２ｄの下端輪状面２２ｄａと回転軸２３の大径部分２３ｂｂの上端輪状面２３ｂｃとの間に当接部材の厚み相当の対向面間距離Ｃを確保する過嵌合阻止手段を設ける。【選択図】 図１
