A medical liquid injection system capable of automatically preventing a piston drive mechanism from being driven when a cylinder holding mechanism does not hold a medical liquid syringe properly. When a cylinder member (210) is being held, in a specific direction of rotation about the axis of the mechanism, by a cylinder holding mechanism (120), an RFID chip (230) and an RFID reader (131) become communicable, making the piston drive mechanism operable. On the other hand, when the cylinder member (210) has been rotated by a specified angle from a specific direction, the RFID chip (230) and the RFID reader (131) become incommunicable, not making the piston drive mechanism operable. As a consequence, the piston drive mechanism is not driven when the cylinder holding mechanism (120) is not holding the medical liquid syringe properly.
