Printing cartridge for a camera and printer combination including an authentication device
View Patent ↗A printing cartridge for a camera that incorporates an inkjet printer includes a housing that can be engaged with the camera. An ink supply arrangement is positioned in the housing and is connectable to an ink feed arrangement of the printer to feed ink to the printer when the housing is engaged with the camera. A print media supply arrangement is positioned in the housing and incorporates a roll of print media. The housing defines an exit slot from which the print media can be fed. A print media feed arrangement is positioned in the housing and is operable to feed print media from the exit slot. An integrated authentication circuit is positioned on the housing to be queried by circuitry positioned in the inkjet printer. The authentication circuit stores data relating to at least one of the ink and the print media.
1. A printing cartridge for refill of a camera that incorporates an inkjet printer, the printing cartridge comprising
a housing that can be engaged with the camera;
an ink supply arrangement that is positioned in the housing and is connectable to an ink feed arrangement of the printer to feed inkjet ink to the printer when the housing is engaged with the camera;
a print media supply arrangement that is positioned in the housing and incorporates a roll of print media, the housing defining an exit slot from which the print media can be fed;
a print media feed arrangement positioned in the housing and operable to feed print media from the exit slot; and
an integrated authentication circuit positioned on the housing, said integrated authentication circuit being configured such that it can be queried by circuitry positioned in the camera, the authentication circuit storing data relating to at least one of the ink and the print media.
2. A printing cartridge as claimed in claim 1 , in which the print media supply arrangement includes a cylindrical former on which the roll of print media is positioned, the ink supply arrangement being an ink cartridge that is received in the former, the ink cartridge including a closure arrangement that is configured to open when the housing is engaged with the printer.
3. A printing cartridge as claimed in claim 2 , in which the ink cartridge is generally cylindrical to be concentrically positioned with respect to the former, the ink cartridge defining a number of ink reservoirs that extend a length of the cartridge, each reservoir containing a different ink.
4. A printing cartridge as claimed in claim 1 , in which the print media feed arrangement includes a roller assembly that engages an end of the print media and that can be engaged with a drive mechanism of the printer when the housing is engaged with the printer.
5. A printing cartridge as claimed in claim 4 , in which the roller assembly includes a drive roller that can be engaged with the drive mechanism of the printer and a pair of driven rollers, the rollers being relatively positioned to carry out a de-curling operation on the print media.
6. A printing cartridge as claimed in claim 1 , in which the authentication circuit stores data that relates to both the ink and the print media.
7. A printing cartridge as claimed in claim 1 , in which the authentication circuit stores the data in an encrypted format.
