ADAPTER ON INKJET PRINTER AND INK CARTRIDGE USED THEREWITH

摘要

The present invention relates to an adapter on jet printer and its corresponding ink cartridge. The adapter comprises a chamber for accommodating the ink cartridge and a chip set on the adapter. The contact surface of the chip and the printer is set with an information contact that is electrically connected with the printer and two detecting contacts. The opposite back surface of the chip with two detecting contacts is set with a non-contact trigger switch. The non-contact trigger switch is electrically connected with two detection contacts respectively. The non-contact trigger switch is triggered to become disconnected at least once by the non-contact trigger mechanism on the ink cartridge when the ink cartridge is inserted into the printer, after which it is not triggered by the non-contact trigger mechanism so as to go to the connected status. Therefore, when the ink cartridge is inserted into the printer adapter, it is disconnected at least once. When the ink cartridge is taken out from the printer adapter which is not taken out from the printer, the chip is disconnected from the printer. This solves the existing technical problem that the adapter must be taken out from the printer when reinstalling the ink cartridge into the adapter.
