    • An administering device capable of quantitatively spraying a multi-dose of powdered medicine includes a device body (1), a storage chamber (3) detachably provided in the device body, the storage chamber (3) being capable of storing powdered medicine, the amount of which corresponds to a plurality of administering operations, an accommodation chamber (10) capable of accommodating powdered medicine, the amount of which corresponds to a single administering operation, and a medicine dispensing rotor (6) movably attached to the device body. The medicine dispensing rotor communicates the accommodation chamber with the storage chamber at a charging position (3a) and communicates the accommodation chamber with the outside of the device body at an administering position (5a) so that the powdered medicine in the accommodation chamber can be administered. A cap (20) is provided for moving the medicine dispensing rotor between the charging position and the administering position. A pump means (8) is provided for injecting air into the storage chamber through the accommodation chamber at the charging position so that the powdered medicine in the storage chamber can be stirred and a predetermined quantity of powdered medicine that has been stirred can be charged from the storage chamber to the accommodation chamber by the suction force of the pump means and/or gravity.
