摘要： There are provided a capping device capable of sealing a recording head mounted on a carriage and of sucking and discharging ink from the recording head, and a wiping member which advances to a moving path of the recording head and wipes waste ink off a nozzle forming surface of the recording head to clean the nozzle forming surface. A first drainage-amount integrating device for integrating and counting an amount corresponding to the waste ink to be wiped off the recording head by the wiping member is provided, and it is possible to prevent the contamination of the interior of the apparatus by excess waste ink.

摘要： A cap member (10) which is brought into contact with a nozzle forming surface of a recording head (15) to seal up the nozzle forming surface, and a wiping member (11) which may be brought into sliding contact with the nozzle forming surface of the recording head (15) are disposed on a cap holder (31). With progress of a cleaning operation in which ink is placed under a negative pressure, and sucked and discharged from the recording head, a cap retaining member (50) is moved upward and placed to a set state, whereby blocking the slanting and downward movement of the cap member (10). Then, the wiping member (11) located on the cap holder (31) slides on the nozzle forming surface to wipe the nozzle forming surface. To a flushing operation, the cap retaining member (50) is moved downward and placed to a reset state. In this state, the wiping member (11) does not slide on the nozzle forming surface.

摘要： A valve unit is arranged in an ink supply path located between an ink cartridge and a recording head in an ink jet recording apparatus. The valve unit controls the opening and closing of the ink supply paths between the ink cartridge and the nozzle openings during a cleaning operation of the recording head. Air bubbles entered into the recording head when the ink cartridge is replaced are discharged by opening the valve unit after applying negative pressure within a cap covering the nozzle openings. By closing valve units disposed on the other recording head that does not receive a new ink cartridge, unnecessary ink suction discharging ink equally through all nozzle openings can be avoided.
摘要翻译：阀单元布置在喷墨记录装置中位于墨盒和记录头之间的墨供给路径中。在记录头的清洁操作期间，阀单元控制墨盒和喷嘴孔之间的供墨路径的打开和关闭。当更换墨盒时，进入记录头的气泡通过在覆盖喷嘴开口的盖中施加负压之后打开阀单元来排出。通过关闭设置在不接收新墨盒的另一个记录头上的阀单元，可以避免不必要的墨吸附通过所有喷嘴开口排放均匀的墨水。

摘要： A printer includes a recording head having a nozzle through which ink is ejected onto a paper sheet and a waste tank in which the ink is retained as waste liquid after having been drained from the recording head. A deposit of the waste liquid is formed in the waste tank. The printer has a suction pump used for forcibly drawing and draining the ink from the nozzle. The suction pump functions also as a gas blasting device that blasts gas to the deposit in the waste tank for blowing off the deposit. This suppresses the amount of the ink consumed in maintenance of the printer.

摘要： The present invention allows the production of a polymerizable hyperbranched polyester by introducing polymerizable unsaturated double bonds into the molecular terminals of a hyperbranched polyester polyol (A), which is obtained by condensation polymerization a polyhydroxy monocarboxylic acid in which there are at least two hydroxyl groups, the carbon atom adjacent to the carboxy group is saturated carbon atom, and the hydrogen atoms on said carbon atom are all substituted, by reacting the hyperbranched polyester polyol (A) and an alkyl ester of a carboxylic acid having a polymerizable unsaturated double bond (B) by a transesterification in the presence of at least one type of transesterification catalyst (C) selected from the group consisting of a dialkyl tin oxide and a stanoxane, without causing side reactions such as nucleophilic addition reactions of terminal hydroxyl groups to polymerizable unsaturated double bonds of the hyperbranched polyester polyol (A), or thermal polymerization of the polymerizable unsaturated double bonds. The polymerizable hyperbranched polyester can be produced at high efficiency using a transesterification that uses as an alkyl ester of a carboxylic acid having a polymerizable unsaturated double bond (B), which is easily obtained as an industrial raw material, and without altering the original backbone structure of the molecular chains of the hyperbranched polyester polyol (A) by hydrolysis and so forth.

摘要： The recording medium guide member is placed along the main scanning direction scanned by the carriage mounted with a recording head, and ink-receiver holes for receiving ink discharged from the recording head are formed on the guide member in positions beyond the edges of the recording medium being conveyed. Ink absorbing materials are placed in said ink-receiver holes, and a discharged ink accumulating means that cumulatively counts the amount of ink discharged into the ink absorbing materials is provided. The amount of ink discharged into the ink-receiver holes can be controlled by the discharged ink accumulation means so that contamination of the left and right edges or the top and bottom as well as left and right edges of the recording medium, caused by excessive ink collecting in the ink-receiver holes, can be avoided.
