Handheld mobile communications device incorporating a pagewidth printer apparatus
View Patent ↗A handheld mobile communications device includes a chassis. Mobile communications circuitry and components are mounted on the chassis. A printer apparatus is mounted on the chassis. The printer apparatus has a pagewidth printhead and an ink supply module arranged on the printhead. A print media feed mechanism is mounted on the chassis to feed print media through the 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, and
the pagewidth printhead is a printhead chip 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 , in which 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 , in which 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 chip.
4. A handheld mobile communications device as claimed in claim 3 , in which the macro-channel molding defines flow control baffles within each ink supply chamber.
5. A handheld mobile communications device as claimed in claim 1 , which includes 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 , in which the print media feed mechanism includes entry feed rollers for picking up the print media as it is fed into the entry slot.
