Abstract
Notification is made to a user when mechanical engagement of an ink tank has been ensured such that the user does not stop a mounting operation before completion of mounting of the ink tank. A substrate includes a light emitting unit and a control unit configured to control the light emitting unit in accordance with a conduction state between an electrode and a corresponding electrode. A liquid tank is moved by force, a second engagement unit is locked to a second lock unit, and the liquid tank is mounted into a holder at a mounting completion position. In the movement, after the liquid tank has gone past the mounting completion position and a second engagement unit has shifted to a state of being partially engaged with the second lock unit, the electrodes shift from a non-conductive state to a conductive state.
