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 syringeS of a size other than the maximum size is appropriately held by the cylinder holding mechanism, RFID chipis located on the side at the rear of metallic cylinder holding mechanism. A pair of resonance antennas are disposed on the left and right of the RFID chip, and an RFID readeris disposed below the resonance antennas. When the liquid syringeS is appropriately held by the cylinder holding mechanism, RFID chipwirelessly communicates with RFID readerfavorably, and the piston driving mechanism can be operated only in this state.
