Ink jet recording device capable of reliably discharging air bubble during purging operations

摘要

An ink jet head 31 is formed with two rows of ink ejection channels 33. A manifold 40 is provided for supplying ink from an ink cartridge 50 to the ink jet head 31. The manifold 40 has an ink supply path 43. The ink supply path 43 includes a connection path 44 fluidly connected with the ink cartridge 50 and a broad portion 45 which encompasses ink inlet ports 33a. The broad portion 45 broadens from the connection path 44 toward the end of ejection channels 33. A float 46 is provided in the broad portion 45. The float 46 serves as a guide member for guiding ink form the connection path 44 to flow along the inner surface of the broad portion 45 in a rapid speed.
