1. A supply unit in which a liquid container including a coupling portion having elasticity is detachably mounted, comprising:
a liquid introduction unit coupled to the coupling portion of the liquid container;
an urging member that urges the liquid container in an uncoupling direction which is a direction opposite to a coupling direction, the coupling direction being a direction in which the liquid container is coupled to the liquid introduction unit; and
an engagement lever having an engaging portion that engages with the liquid container when the liquid container is coupled to the liquid introduction unit, wherein
the engagement lever includes an operating portion configured to be displaced by an operation of a user and a pressing portion configured to press the liquid container, and
due to a displacement of the operating portion from a stopping position to an operation position, the engagement lever is configured to release engagement of the engaging portion with the liquid container and to press the liquid container in the uncoupling direction by the pressing portion.
