Medicine feeder

A medicine feeder comprising:

• an outer rotary body having therein an internal space that has an opening portion opening upward and an annular upper end surface that surrounds the opening portion, the outer rotary body being rotatable about a virtual vertical line that extends in an up-down direction within the internal space;
• an inner inclined rotary body disposed in the internal space of the outer rotary body capable of rotating about a virtual inclined line, which is inclined with respect to the vertical line, with a plurality of solid medicine pieces being placed on an upper surface portion of the inner inclined rotary body, the inner inclined rotary body moving the plurality of medicine pieces onto the annular upper end surface of the outer rotary body when the inner inclined rotary body is rotated;
• and
• a regulating mechanism operable to align the plurality of medicine pieces, which have been moved onto the annular upper end surface of the outer rotary body, along a rotational direction of the annular upper end surface when the outer rotary body is rotated, wherein:
• a plurality of delivery portions and a plurality of push-up portions are formed in a peripheral edge region of the upper surface portion of the inner inclined rotary body and arranged alternately one by one in a circumferential direction, the plurality of delivery portions each having a downward slope that slopes downward toward an outer side even at an elevated position, and the plurality of push-up portions each having no downward slope;
• when one or more of the medicine pieces are disposed on the downward slope at the elevated position, the plurality of delivery portions are each capable of letting the medicine pieces ride onto the annular upper end surface of the outer rotary body using the downward slope;
• and
• the push-up portions are each capable of pushing up the one or more medicine pieces disposed on the delivery portion located in front of the push-up portion in a direction of forward rotation of the inner inclined rotary body to the elevated position.
