Abstract
A liquid injection system which can be checked that that a liquid syringe is appropriately mounted on a chemical liquid injector and the liquid syringe is filled with a liquid at a time. Pattern 400 appearing as a predetermined shape when it is viewed from above through liquid syringe 200 filled with transparent liquid L is divided between a lower surface of liquid syringe 200 and an upper surface of chemical liquid injector 100. When liquid syringe 200 is appropriately held by chemical liquid injector 100, the pattern on the lower surface of liquid syringe 200 and the pattern on the upper surface of chemical liquid injector 100 are properly combined. If liquid syringe 200 is filled with a transparent liquid in this state, the combined pattern is viewed as the predetermined shape from above liquid syringe 200. The shape can be seen to check that the liquid syringe 200 is appropriately held and filled with liquid L at a time.
