摘要： According to the present invention, there is disclosed a capping device for an ink jet printer which is constructed such that a cap supporting member 14, adapted to move from the non-capping position to the capping position by the thrust action of a carriage 3, is arranged on the home position side of the ink jet printer so that the outer end part of the cap supporting member 14 is displaced toward the nozzle surface of a printing head 4 with the aid of a guide surface 15b having an inclined surface 15a, until a cap 5 on the cap supporting member 14 is brought into close contact with the nozzle surface of the printing head 4 with an adequate intensity of thrust force by means of a turnable lever 8 operatively connected to the inner end of the cap supporting member 14, while resilient force of a cap spring 11 is exerted on the base end part of the turnable lever 8 so as to normally bias the cap supporting member 14 in the direction toward the printing head 4.

摘要： An ink cartridge employable for an ink jet type recording apparatus includes a case (4) having a front plate (4a) with at least one position determining hole (4h/4g) formed therein. An ink bag (1) containing a supply of ink is received in the case (4) in a manner such that the position determining hole (4h/4g) allows the insertion of a position determining shaft (16/17) projecting from an inner end of a cartridge holder (90) through the position determining hole (4h/4g) to guide and properly locate the ink cartridge (80) relative to the cartridge holder (90) without establishing communication between the ink bag (1) and the position determining shaft (16/17). An ink outlet piece (2) having an ink flow path therein communicates with the ink bag (1) so that an ink feeding needle (15) disposed at the inner end of the cartridge holder (90) and slightly behind the position determining shaft (16/17) is capable of piercing through the ink outlet piece (2) to reach an interior of the ink bag (1), the outlet piece (2) being positioned to contact the ink feeding needle (15) after the ink cartridge (80) has been properly located relative to the cartridge holder (90) by the position determining hole (4h, 4g) and the position determining shaft (16/17).

摘要： An ink chamber is formed with a vent port allowing atmospheric air to enter therein and an ink outlet from which ink is taken out. An optical member has an ink contact face capable of contacting with ink contained in the ink chamber. The ink contact face includes a detection face at which a remaining amount of ink in the ink chamber is optically detected in accordance with an amount of air entered into the ink chamber via the vent port. A first ink absorbing member is disposed in the vicinity of the ink contact face, and capable of absorbing the ink in the ink chamber.

摘要： A multicolor-use ink cartridge 1 has obverse surface-side ink chambers 5(1) and 5(2) formed on an obverse surface side of a horizontal plate portion 31 of a rigid plastic plate 3 and reverse surface-side ink chambers 6(1) and 6(2) formed on a reverse surface side thereof. Since these ink chambers are arranged in a breadthwise direction so as to be staggered in a mutually overlapping state with the horizontal plate portion 31 interposed therebetween, it is possible to make small the dimension in a direction in which the ink chambers are arranged. The respective ink chambers are formed by joining flat portions 53b to 64b of three-dimensionally molded flexible plastic films 53, 54, 63, and 64 to obverse surface-side recesses 51 and 52 formed on the obverse surface of the horizontal plate portion 31 and reverse surface-side recesses 61 and 62 formed on the reverse surface thereof, respectively. Therefore, it is possible to form ink chambers having high sealability.

摘要： An ink tank of the foam type which is provided with a detected portion capable of exactly and surely detecting the amount of ink used by the printer or remaining in the ink tank. The ink tank includes a sub ink chamber that is diposed or formed between a main ink chamber and an ink outlet of an ink tank of a foam type. When an amount of air flowing into the sub ink chamber increases, one or more reflecting surfaces of a right-angled prism, which function as ink interfaces, resume their original function of reflecting surfaces, thereby enabling the detection of an ink end. Air bubbles having entered the sub ink chamber are surely led onto the one or more reflecting surfaces by a bubble storage part. At an ink passage having a narrow width, which is defined by the one or more reflecting surfaces, air bubbles are pressed against the one or more reflecting surfaces to be put to a crushed state and in surface contact with the latter. Air bubbles are surely led onto the one or more reflecting surfaces, and are crushed and pressed against the reflecting surfaces. This configuration prevents the one or more reflecting surfaces from being covered with ink retained in spaces among the air bubbles. Therefore, the ink end can be detected surely and exactly.

摘要： An ink jet printer reliably prevents printing defects resulting from bubbles remaining in the ink path after ink priming. An ink suction mechanism of the ink jet printer performs a post-priming head recovery process for suctioning ink from the nozzles when an hour passes after the ink priming process. This process suctions a large volume of ink from the ink nozzles, and can thus reliably expel bubbles from the ink path. By performing this process at a sufficiently long specific period of time after ink priming, enough time has elapsed for bubbles that are formed by the ink path filter during ink priming and collect in offsets in the ink path to grow to a size where the bubbles protrude from the offset into the ink path. Bubbles that are thus freed into the ink path can therefore be reliably expelled from the nozzles. Printing defects resulting from bubbles left by ink priming can thus be reliably prevented.
摘要翻译：喷墨打印机可靠地防止在油墨启动之后留在油墨通道中的气泡所引起的打印缺陷。喷墨打印机的吸墨机构在油墨填充处理之后经过一小时后，执行用于从喷嘴抽吸墨水的后填充头恢复过程。该过程从墨嘴吸入大量的墨水，因此可以可靠地从油墨通道排出气泡。通过在油墨启动之后足够长的特定时间段进行该处理，在油墨启动期间由墨水通道过滤器形成的气泡已经经过足够的时间，并且在油墨通路中以偏移量收集成长到气泡突出的尺寸从偏移到油墨路径。因此，可以将从而释放到油墨路径中的气泡可靠地从喷嘴排出。因此可以可靠地防止由于通过喷墨留下的气泡造成的印刷缺陷。
