Description

577821 A7 ~ _______ B7 V. Description of the invention (彳) Background of the month This month is about the technology of identifying an ink cartridge, which supplies ink to a recording head under appropriate negative pressure, and ejects ink droplets in response to a print signal. . The ink recording device is usually shaped so that an inkjet recording head that ejects ink droplets after responding to a print signal is mounted on a carriage that reciprocates in the width direction of the record sheet, and at the same time enables the ink to flow from an external ink The sink is supplied to the mouthpiece. In the small-size recording head, an ink storage container such as an ink tank or the like may be separately attached to a carrier. On the other hand, in the general-type recording head, the ink-bearing storage container is set on the frame or housing of the recording device, and is connected to the recording head via an ink supply pipe. The ink tank installed on the carrier is usually shaped so that a porous member such as sponge or the like is stored in the ink tank and soaked with ink to reduce the pressure change caused by ink fluctuations or similar phenomena. Caused by the reciprocating movement of the carrier. Even when the recording head is supplied with ink from a large-capacity ink bag set on a frame body through an ink supply tube, the ink passes a damping function to prevent the ink pressure from changing due to the movement of the carrier. The stage tank is supplied to the green head, which prevents the ink pressure from being changed due to the carrier's reciprocating movement causing the tube to bend. Therefore, the former has a problem in that the size and weight of the ink tank are increased due to the valley of the porous member contained in the ink tank compared with the ink volume that can be contained in the ink tank. The latter has a problem in the structure of the recording device because a mechanism is required to prevent the ink pressure from being complicated due to changes in vibration. The purpose of improving the quality of prints and the inks applicable to the recording head are specified by the producer. —- 4-This paper size applies Chinese National Standard (CNS) A4 specification (210X 297 mm) A7 Description of the invention-Wan Nian, because of the ink cartridge self-pull view + + " The structure is set to a similar direction of the sun 3 And shaped into a rectangular flat rod assembly, ~ ^; ^ Yu Ji Lu Gu Qi's problem is the application of Qiu Aizhi's ink cartridges, it may be difficult ^ to to ^ Although I do, you may choose the wrong.
