Abstract
A chemical liquid injection system which a piston driving mechanism is driven only when a cylinder holding mechanism appropriately holds liquid syringes of various sizes through a cylinder adapter and such manner. When the liquid syringe 200S of a size other than the maximum size is appropriately held by the cylinder holding mechanism 120, RFID chip 230 is located on the side at the rear of metallic cylinder holding mechanism 120. A pair of resonance antennas are disposed on the left and right of the RFID chip, and an RFID reader 131 is disposed below the resonance antennas. When the liquid syringe 200S is appropriately held by the cylinder holding mechanism 120, RFID chip 230 wirelessly communicates with RFID reader 131 favorably, and the piston driving mechanism can be operated only in this state.
