LIQUID JET HEAD, LIQUID JET RECORDER AND METHOD FOR FILLING LIQUID JET HEAD WITH LIQUID

摘要

To enhance a degree of freedom in design of a liquid jet recorder by improving the space factor of a liquid jet head.  To prevent pollution caused by excess liquid and to attain an initial filling into a liquid jet recorder by improving an ability to collect excess liquid with simple configuration, and liquid jet is stabilized after the liquid filling.  A liquid jet head characterized by comprising an open/close mechanism (60) which opens a wall portion opening (24n) in an open state to expose a nozzle hole to the outside, and closes the wall portion opening (24n) in a closed state to constitute a closed space between the wall portion (24) and a nozzle plate (31), a suction channel (15) which has one end side that opens as a suction port (15a) below a nozzle array and the other end side that is connected with a suction pump (16), which turns the closed space to a negative pressure chamber (R) by evacuating the closed space by means of the suction pump (16), and which supplies ink (I) from the ink tank of ink (I) to the nozzle hole, and an atmosphere release channel (33) which can switch between the closed space opend to the outside and that closed thereto.
