  Cellphone printer with internal ink storageUSPTO Application #: 20070222847Title: Cellphone printer with internal ink storage Abstract: A printer is provided for a mobile telephone. The printer includes a housing having a pair of elongate moldings capable of being connected together to define an ink ejection slot. The housing also includes an endcap configured to engage with an end of the moldings. An ink supply cartridge is housed within the housing and defines a plurality of ink storage reservoirs for storing respective types of ink. A printhead module is also housed within the housing and defines a plurality of ink distribution channels in fluid communication with respective ink storage reservoirs. The printhead module includes an elongate array of ink ejection nozzles in fluid communication with the ink distribution channels and aligned with the ink ejection slot so that ink can be ejected through the ink ejection slot.

CROSS REFERENCES TO RELATED APPLICATIONS [0001] The present application is a continuation application of U.S. patent application Ser. No. 10/503,924 filed on Aug. 9, 2004, which is a 371 of PCT/AU03/00169 filed on Feb. 12, 2003 all of which are herein incorporated by reference. FIELD OF THE INVENTION [0002] This invention relates to mobile telecommunications devices, in particular mobile telephones, and peripheral devices giving current mobile telephones greater functionality. Specifically, the present invention relates to mobile telephones having an internal colour printer. BACKGROUND [0003] In recent years, the commercially successful models of mobile telephones have been the ones which have been the most compact. The desire for small size has prevented other devices, most notably printers, from being incorporated into the housings of mobile telephones. [0004] Prior art printers incorporate a supply of print media into the printer and employ a print media feed mechanism to transport the print media past the printhead(s) to effect printing onto the print media. It is essential during a printing operation to synchronise the speed of the print media with the printing rate of the printhead(s) to ensure a faithful reproduction of the image being printed. Heretofore, the synchronisation of the print media with the printhead(s) has been relatively simple to accomplish because the print media feed mechanism, including the supply of print media, forms an integral part of the printer. The speed of the print media is therefore known and fixed, as is the speed at which the printhead(s) and print controller operate, with synchronisation between these features being accomplished using simple mechanical features such as gears, stepper motors and the like. [0005] Such features however, in particular the need to have a supply of print media accommodated within the printer, have made these printers larger and heavier than they otherwise need be. Even in more compact printers employing a monolithic page-width drop-on-demand printhead arrangement of the type described in the above mentioned co-pending applications, where the printhead is fixed, there is still a need to have a supply of print media and a print media drive mechanism integral to the printer to ensure proper synchronisation between ink ejection and the motion of the print media. Up until now these requirements have limited the minimum possible printer size and have precluded the possibility of a printer being incorporated into a device such as a compact mobile telephone.
