ADAPTER ON INKJET PRINTER AND INK CARTRIDGE USED THEREWITH

摘要

An adapter (2) on an inkjet printer and an ink cartridge (5) used therewith are disclosed. The adapter includes a chamber containing the ink cartridge and a chip (1) disposed outside of the adapter. An information contact and two detection electric contacts for connecting electrically to the printer are arranged on a surface of the chip contacting with the printer. A non-contact triggering switch (3) is arranged on a back surface of the chip opposite to the two detection electric contacts, and connected to the two detection electric contacts respectively. During the insertion of the ink cartridge into the printer, the non-contact triggering switch is triggered to switch off at least one time by a non-contact triggering mechanism (4) on the ink cartridge. After the ink cartridge is inserted, the non-contact triggering switch is not triggered by the non-contact triggering mechanism, and thus the non-contact triggering switch is in ON state. When the ink cartridge is drawn out from the adapter, the chip can be disconnected with the printer while the adapter is drawn out from the printer. When the ink cartridge is to be inserted into the adapter again, there is no need to draw out the adapter from the printer.
