Handheld mobile communications device with integral internal printer, incorporating a receptacle with an authentication interface
View Patent ↗A handheld mobile communications device comprising: a support structure; an antenna mounted on the support structure for transmitting and receiving radio signals; radio signal processing circuitry positioned on the support structure to process the radio signals; a speaker and microphone arrangement positioned on the support structure and operatively connected to the radio signal processing circuitry; a printhead positioned on the support structure to carry out a printing operation; and an interface for enabling interrogation of an authentication means associated with an ink cartridge.
1. A handheld mobile communications device comprising:
a support structure;
an antenna mounted on the support structure for transmitting and receiving radio signals;
radio signal processing circuitry positioned on the support structure to process the radio signals;
a speaker and microphone arrangement positioned on the support structure and operatively connected to the radio signal processing circuitry;
a printhead positioned on the support structure to carry out a printing operation; and
a processor configured for connection to an authentication means associated with an ink cartridge to determine its suitability for use with the printhead, and operating the printhead accordingly.
2. A communications device as claimed in claim 1 , in which the radio signal processing circuitry and the printing processing circuitry are configured so that the printing processing circuitry and the radio signal processing circuitry can function simultaneously.
3. A communications device as claimed in claim 2 , in which the radio signal processing circuitry and the printing processing circuitry are in the form of at least one application specific integrated circuit.
4. A communications device as claimed in claim 1 , in which the radio signal processing circuitry is that of a mobile telephone.
5. A communications device as claimed in claim 1 , in which the printhead is a pagewidth printhead.
6. A communications device as claimed in claim 5 , which includes an ink distribution unit that is arranged on the printhead to supply ink to the printhead.
7. A communications device as claimed in claim 1 , which includes a print media feed mechanism for feeding print media relative to the printhead so that the printing operation can be carried out on the print media.
8. A communications device as claimed in claim 1 , wherein the processor is an application specific integrated circuit for interrogating an authentication chip in the cartridge.
