Handheld mobile communications device with an image sensor and a detachable printing mechanism

1. A handheld mobile communications device comprising:

a support structure;

radio signal processing circuitry positioned on the support structure and configured to receive and transmit radio signals;

an image sensor positioned on the support structure for electronically capturing an image;

image processing circuitry positioned on the support structure and operatively connected to: the image sensor to receive the electronically captured image; and the radio signal processing circuitry;

a receptacle for receiving a detachable printing mechanism, the receptacle including an interface enabling connection of the printing mechanism to the image processing circuitry, thereby enabling images processed by the image processing circuitry to be printed by the printing mechanism when it is operatively positioned within the receptacle.

2. A communications device as claimed in claim 1 , in which the printing mechanism includes a pagewidth printhead and an ink distribution unit mounted on the printhead to supply ink to the printhead.

3. A communications device as claimed in claim 2 , in which the printhead includes a printhead chip that spans a print media pathway, the printhead chip defining a plurality of ink inlets for the supply of ink to the printhead chip.

4. A communications device as claimed in claim 3 , in which the ink distribution unit defines a number of discrete ink supply chambers and a plurality of ink pathways interposed between the ink supply chambers and said ink inlets, the ink pathways converging towards the ink inlets so that each ink inlet is supplied with ink from a respective ink pathway.

5. A communications device as claimed in claim 1 , in which the radio signal processing circuitry is configured to process radio signals of the type transmitted and received by a mobile telephone.
