Abstract

A page-wide liquid ejection head detachable from a main body of a liquid ejection apparatus includes a supply connector connected to the main body and adapted to allow passage of a liquid supplied tothe liquid ejection head; and a recovery connector connected to the main body and adapted to allow passage of the liquid recovered from the liquid ejection head, wherein the supply connector and the recovery connector are placed at one end in a longitudinal direction of the liquid ejection head. The invention also provides a liquid ejection apparatus.

Description

technical field [0001] The present disclosure relates to a liquid ejection head and a liquid ejection device. Background technique [0002] For example, Japanese Patent Application Laid-Open No. 2010-30206 discloses a page-wide type liquid ejection head provided with a supply port and a discharge port (recovery port) of ink, and also discloses a liquid ejection head device, the liquid ejecting device is equipped with the liquid ejecting head. The ink supplied through the supply port is discharged from the discharge port by circulating through the liquid ejection head. Also, the liquid ejection head is connected to the main body of the liquid ejection device via the supply port and the discharge port, thereby being configured to be removable from the main body. [0003] Currently, in the configuration disclosed in Japanese Patent Application Laid-Open No. 2010-30206, the supply port and the discharge port serving as a connection portion of the liquid between the liquid ejec...
