To provide a medicine portion packaging apparatus capable of downsizing a mechanism for cutting medicine wrapping paper into pieces.SOLUTION: A medicine portion packaging apparatus comprises: a medicine wrapping paper storing part in which medicine wrapping paper folded into V-shape is wound up; a transfer route which transfers the medicine wrapping paper pulled out from the medicine wrapping paper storing part; a heat-sealing part which is arranged in the middle of the transfer route and forms heat seals for sectioning the medicine wrapping paper for each package; a medicine supplying part which is arranged in the middle of the transfer route and supplies a medicine for each package into a space between the medicine wrapping paper; a driving roller which performs transferring/driving while holding the medicine wrapping paper in which the medicine supplied by the medicine supplying part is stored; and a rotary cutter which cuts a portion heat-sealed by the heat-sealing part in the medicine wrapping paper transferred by the driving roller. The rotary cutter has: a fixed blade which is set on one side of the medicine wrapping paper in the transfer direction; and a rotary blade which is set on the other side of the medicine wrapping paper in the transfer direction, has a blade tip in which a shear angle formed between the fixed blade and itself becomes wider as it goes downward, and cuts the medicine wrapping paper between the fixed blade and itself.SELECTED DRAWING: Figure 6
