Ink supply mechanism for a disposable camera printing system

摘要

The invention provides for an ink supply mechanism for a disposable camera printing system. The printing system of the disposable camera includes a printhead with a series of holes etched in a back surface thereof for the supply of ink to a front surface of the printhead for subsequent ejection onto print media stored on a roll housed in the camera. The ink supply mechanism includes a cartridge for supplying ink to the printhead and a platen for guiding the print media under the printhead. The cartridge has elongate top and bottom molding pieces operatively engaged in a complementarily manner to define a plurality of elongate ink reservoirs. The bottom moulding piece supports the printhead and has guide walls and block portions for arranging the ink reservoirs in fluid communication with the series of holes. The platen has a base with a pinch roller and a cutting mechanism attached thereto, the cutting mechanism having a cutting wheel operatively running on a threaded rod to cut the media from the roll.
