A chemical-liquid injection head including a syringe holding unit which holds a syringe in which a piston member is slidably inserted into a cylinder member having a circular cylindrical shape, a piston driving mechanism having a ram member for moving the piston member of the syringe, and a first light emitting portion which emits light with a first color and illuminates the syringe and a second light emitting portion which emits light with a second color and illuminates the syringe. The first light emitting portion and the second light emitting portion, viewed in a posture at the time of use of the injection head, are provided at an upper side of the ram member.

A safe and easy handling of a chemical-liquid circuit having various components. The opening/closing unit drive mechanism includes an opening/closing unit holder which detachably holds an opening/closing unit which includes a housing having flow channels and a piston for opening and closing the flow channels which is movably provided to the housing, a hook to be engaged with the piston of the opening/closing unit, which is disposed leaving a space from the opening/closing unit holder, and a linear motion mechanism which moves the hook back and forth. The opening/closing unit holder is movably supported between a first position at which the piston is engaged with the hook and a second position at which the piston is not engaged with the hook.
