Abstract:
1. A liquid ejection device comprising: a liquid ejection head for ejecting liquid; and a liquid container storing liquid to be supplied to the liquid ejection head and adapted to be loaded in the liquid ejection head, the liquid container having a contact substrate arranged on a surface thereof, the contact substrate having a contact surface located close to the liquid ejection head as the liquid container is loaded in the liquid ejection head, the liquid ejection head having a connector arranged at a position located vis-à-vis the contact substrate of the loaded liquid container and a connection substrate electrically connected to the connector, the connector including a contact spring capable of expanding and contracting in an axial direction, the contact spring having a front end section contacting the contact surface of the contact substrate of the loaded liquid container and a rear end section contacting the connection substrate, and the contact surface of the contact substrate being inclined relative to the axial direction of the contact spring so as to displace the front end section of the contact spring along the contact surface while being held in contact with the contact surface during an operation of loading the liquid container in the liquid ejection head.
