IX. Description of the invention: [Technical field to which the invention pertains] The present invention relates to an ink supply carrier, and more particularly to a (4) carrier printing mechanism suitable for the ink supply system. [Prior Art] In general, inkjet printers are popular with consumer screens because of their ease of operation and can be printed on a variety of inkjet media, but inkjet printers use - after a while, The ink will need to be replaced due to the exhaustion of the ink. The current common replacement method is to discard the old ink and install a new ink to provide ink. This not only causes waste of the ink cartridge, but also The price of ink S is expensive and invisibly increases the user's overhead. In order to save printing costs and avoid waste of resources, the continuous use of the same ink cartridge % of the continuous ink supply system was born. The existing continuous ink supply system is an external continuous ink supply system, which is provided with an ink supply cartridge outside the inkjet printer, and is connected to the ink cartridge and the ink cartridge inside the inkjet printer by a pipeline. The principle of vacuum ink guiding ink is introduced into the ink cartridge from the ink supply cartridge, and then the ink of the ink supply cartridge is visually observed to consume the shape of the moon and the ink is replenished to the ink cartridge in time to achieve the ink supply without interruption. Continuous ink supply. However, the above continuous ink supply system has many limitations and inconveniences in its use. First, the height of the ink supply must be on the same plane as the inkjet printer, and the ink level of the ink supply should be slightly lower than that of the inkjet printer to avoid the ink being damaged. The ink overflows from the ink outlet due to excessive hydraulic pressure from the ink supply.
其次，當連續供墨系統墨水匣内部之墨水用盡時，供 墨匣可更換地與承載座分離，因此更換供墨匣的重點在於 必須容易插拔及安裝，然而習知的列印機構在安裝墨水匣 時，往往會因為使用者為了使供墨匣能緊密安裝於承載座 上，而施予過當的力量，使供墨匣在安裝的過程中受到損 壞，另外，在取出時，也可能會因為先前供墨匣安裝於承 載座時安裝太緊，使其取出不易，而造成更換時的不方便。 因此，如何發展一種可改善上述習知技術缺失之具有 退匣結構之供墨匣承載座及其所適用之列印機構，實為目 前迫切需要解決之問題。 【發明内容】 本案之主要目的在於提供一種具有退匣結構之供墨 匣承載座及其所適用之列印機構，藉由供墨匣承載座之彈 性抵頂元件和卡扣部件，使供墨匣置入容置槽中時，會壓 迫彈性抵頂元件，且供墨匣之底座扣合於卡扣部件之凹陷 部内，使供墨匣固定於容置槽内，而在更換供墨匣時，藉 由按壓卡扣部件使供墨匣之底座脫離卡扣部件之凹陷 部，而供墨匣將受到彈性抵頂部件之反彈作用力的推動而 7 1335871 部份退出容置槽，以讓使用者可輕易取出供墨IE，俾解決 傳統列印機構在安裝供墨匣時，會因為使用者為了使供墨 匣能緊密安裝於承載座上，而施予過當的力量，使供墨匣 在安裝的過程中受到損壞，且在拔出時，會因為先前供墨 匣安裝於承載座時安裝太緊，使其取出不易，而造成更換 時的不方便等缺點。Secondly, when the ink inside the ink supply system of the continuous ink supply system is used up, the ink supply cartridge is replaceably separated from the carrier. Therefore, the focus of replacing the ink supply cartridge is that it must be easily inserted and installed, but the conventional printing mechanism is When the ink cartridge is installed, it is often because the user applies the force to make the ink cartridge compactly mounted on the carrier, so that the ink cartridge is damaged during the installation process, and when it is taken out, it may be Because the previous ink supply cartridge is installed too tightly when it is mounted on the carrier, it is difficult to remove it, which causes inconvenience in replacement. Therefore, how to develop an ink supply carrier having an untwisting structure which can improve the above-mentioned conventional techniques and a printing mechanism to which it is applied is an urgent problem to be solved. SUMMARY OF THE INVENTION The main object of the present invention is to provide an ink supply carrier having an untwisting structure and a printing mechanism therefor, which are provided by the elastic abutting member and the snap member of the ink supply carrier. When the sputum is placed in the accommodating groove, the elastic abutting member is pressed, and the base of the ink supply cartridge is fastened in the recessed portion of the snap member, so that the ink supply cartridge is fixed in the accommodating groove, and when the ink supply cartridge is replaced By pressing the snap member to disengage the base of the ink supply cartridge from the recessed portion of the snap member, the ink supply cartridge is pushed by the resilient force of the elastic abutment member, and the portion of the portion 1 1335871 is withdrawn from the receiving groove for use. The ink supply IE can be easily taken out, and when the traditional printing mechanism is installed, the user can apply excessive force to make the ink supply 紧密 in order to make the ink supply 紧密 close to the carrier. During the installation process, it is damaged, and when it is pulled out, the previous ink supply is installed too tightly when it is mounted on the carrier, so that it is difficult to remove, which causes inconvenience in replacement.
