PROBLEM TO BE SOLVED: To provide a PTP (press through package) cassette 10 capable of aligning and storing various sheets of PTP packaged tablets 8 and the like with a wide range of widths while preventing a side plate from being obstructive at the time of aligning and storing.SOLUTION: A PTP cassette 10 comprises aligning and storing parts 11, 13 and 17 for holding sheets of PTP packaged tablets 8 in a state of laying the sheets horizontally and stacking the same up vertically, and a sequentially discharging mechanism 15 for moving the lowermost sheet of PTP packaged tablets 8 forward by contacting a movable member 15a thereto at a position of an inner bottom member 13, and is configured to feed the sheets of PTP packaged tablets 8 transversely in order from the lowermost ones and discharge the same from a discharge port 12 toward the front. The aligning and storing parts 11, 13 and 17 are provided with a right side plate 17 (the only side plate) but not with a left side plate. The right side plate 17 is inclined toward the right side with respect to the vertical plane, and the inner bottom member 13 is inclined toward the right side with respect to the horizontal plane. Further, a front plate 11 is inclined toward the front with respect to the vertical plane and forms an obtuse angle θ with the inner bottom member 13.COPYRIGHT: (C)2014,JPO&INPIT【課題】広範な幅の各種PTP包装剤8等を整列収納できるうえ整列収納時に側板が邪魔にならないPTPカセット10を実現する。【解決手段】PTP包装剤8を各々は横にしたうえで縦に積み重ねて整列収納させた状態で保持する整列収納部11+13+17と、最下のPTP包装剤8aに内底部材13の所で可動部材15aを接触させて前進させる順次排出機構15とを備えていて、PTP包装剤8を下から順に横送りして排出口12から前方へ排出するPTPカセット10において、整列収納部11+13+17が、右側板17(唯一側板)を具備して左側板を欠くものであり、右側板17が鉛直面から右側へ傾斜しており、内底部材13が水平面から右側へ傾斜している。また、前板11が鉛直面から前方へ傾斜して前板11と内底部材13との角度θが鈍角になっている。【選択図】 図1
