Abstract
A plurality of cartridges are each provided with a transponder which is operative, in response to an external command signal, to receive and store medicament information including name and quantity of a medicament and to externally transmit the stored medicament information. A discharge quantity of medicament to be discharged from the cartridge is measured, while a current stock quantity of medicament stored in the transponder is read. Then, the discharge quantity of medicament is subtracted from the current stock quantity of medicament, and the balance is written as new stock quantity of medicament into the transponder.
