Handheld mobile communications device incorporating pagewidth printer apparatus

1. A handheld mobile communications device comprising:

a chassis;

mobile communications circuitry and components mounted on the chassis;

a printer apparatus mounted on the chassis, the printer apparatus having a pagewidth printhead and an ink supply module arranged on the printhead; and

a print media feed mechanism mounted on the chassis to feed print media through the printer apparatus, wherein

the ink supply module is a molded multi-part structure defining a plurality of converging ink flow paths,

the printer apparatus is detachable from the chassis for replacement after a predetermined amount of usage, and

the pagewidth printhead is a printhead integrated circuit mounted on the molded multi-part structure to be in fluid communication with the ink flow paths.

2. A handheld mobile communications device as claimed in claim 1 , wherein an image sensor and associated image sensing circuitry are positioned on the chassis so that the device can be used for digital photography, the image sensing circuitry being connected to printing circuitry of the printer apparatus so that the printer apparatus can print photographs.

3. A handheld mobile communications device as claimed in claim 1 , wherein the multi-part structure comprises a cover, a macro-channel molding mounted in the cover and defining a number of ink supply chambers and a micro-channel molding mounted on the macro-channel molding and defining a plurality of converging ink flow nozzles in fluid communication with the printhead integrated circuit.

4. A handheld mobile communications device as claimed in claim 3 , wherein the macro-channel molding defines flow control baffles within each ink supply chamber.

5. A handheld mobile communications device as claimed in claim 1 , further comprising a casing mounted on the chassis, the casing defining entry and exit slots for the passage of the print media through the casing and the printer apparatus.

6. A handheld mobile communications device as claimed in claim 5 , wherein the print media feed mechanism includes entry feed rollers for picking up the print media as it is fed into the entry slot.
