<P>PROBLEM TO BE SOLVED: To provide a recorder which can prevent sticking to an atmosphere opening port of a valve body of an atmosphere communication valve while enlargement and cost increase of the recorder are avoided. <P>SOLUTION: The recorder includes a recording head 5 which ejects an ink, an ink tank which has both an ink bag 307 for storing the ink supplied to the recording head 5 and a housing, and a gas flow passage 508 for pressurizing a space between the ink bag 307 and the housing. The gas flow passage 508 is equipped with the atmosphere communication valve 505 for opening the interior of the gas flow passage 508 to the atmosphere, and a pump 502 which generates pressure change to the space between the ink bag 307 and the housing by circulating a gas via the gas flow passage 508. <P>COPYRIGHT: (C)2012,JPO&INPIT |
