PROBLEM TO BE SOLVED: To provide a recorder capable of performing recovery processing while suppressing the complication of the structure of the recorder. SOLUTION: The recorder 500 has a film 136 which can be deformed with the pressure in a first fluid chamber 101 and a second fluid chamber 110 in at least part of a recording head 100. The recorder 500 also has a negative pressure valve unit 120 which controls the amount of ink supplied to the first fluid chamber 101 and the second fluid chamber 110 and can be opened and closed with the displacement of the film 136. When the negative pressure valve unit 120 is opened, a pressurized ink is supplied to the first fluid chamber 101 and the second fluid chamber 110. COPYRIGHT: (C)2010,JPO&INPIT |
