1. A medicine feeding device comprising:
a tablet case for storing a medicine; a roll from which wrapping paper is supplied in a manner which wraps the medicine discharged from the tablet case in the wrapping paper; and a wrapping paper delivery mechanism which delivers the wrapping paper; wherein the wrapping paper delivery mechanism has a base plate holding the roll of wrapping paper, and an engaging shaft projected from a center of the base plate and engaging with a shaft tube of the roll around which the wrapping paper is wound, an engaging projection is formed on a side face of the engaging shaft, the engaging projection being inclined in a rotational direction of the engaging shaft from one end of the engaging shaft toward the other end of the engaging shaft so as to intersect an axial direction of the engaging shaft at a predetermined angle, and an engaging groove is formed on an inner surface of the shaft tube, the engaging groove being inclined to engage with the engaging projection, wherein when the wrapping paper is delivered from the roll, a force is applied on the shaft tube for further fastening engagement between the engaging projection and the engaging groove, and when the roll abuts on a guide plate which receives the wrapping paper corresponding to a bottom portion of the base plate, and the roll is moved toward the base plate, the shaft tube abuts on a tapered portion of the engaging shaft, and when the shaft tube abuts on the tapered portion and is guided by the tapered portion, the roll is separated from the guide plate to be raised and an axial center of the roll coincides with an axial center of the engaging shaft.
