Abstract

The present invention relates to a charging stand for charging a mobile phone. The stand includes a base defining a receptacle configured to receive the mobile phone. A battery charging circuit includes a power cord extending into the base, step-down circuitry for reducing supplied voltage from the cord, and exposed contacts configured to supply the reduced voltage to a battery of the mobile phone received in the receptacle. A removable ink cartridge is received in the receptacle and is configured to supply ink to a printer of the mobile phone received in the receptacle.

Claims

1. A charging stand for charging a mobile phone, the stand comprising:

a base defining a receptacle configured to receive the mobile phone;

a battery charging circuit including a power cord extending into the base, step-down circuitry for reducing supplied voltage from the cord, and exposed contacts configured to supply the reduced voltage to a battery of the mobile phone received in the receptacle; and

a removable ink cartridge received in the receptacle and configured to supply ink to a printer of the mobile phone received in the receptacle.

2. A charging stand as claimed in claim 1, wherein the base includes a backrest and a pair of spaced lateral walls extending from the backrest which together define the receptacle, and the ink cartridge is received between the mobile phone and the backrest.

3. A charging stand as claimed in claim 1, wherein the step-down circuitry includes a Printed Circuit Board located within the base and a rectifier mounted to the PCB for rectifying an AC supply voltage to a DC output voltage.

4. A charging stand as claimed in claim 1, wherein the step-down circuitry includes a Printed Circuit Board located within the base and a voltage regulator means mounted to the PCB for regulating an automotive DC supply voltage to a mobile phone DC supply voltage.

5. A charging stand as claimed in claim 1, in which the base includes a speaker connected to a protruding speaker plug in the receptacle.

6. A charging stand as claimed in claim 1, in which an inlet connector is located at the base of the receptacle to receive gravity fed ink from the ink cartridge.

7. A charging stand as claimed in claim 6, in which an outlet connector is located at the base of the receptacle to supply the gravity fed ink to the printer.

8. A charging stand as claimed in claim 7, wherein the connectors each include four passages through which three coloured inks and black ink are transported.

9. A charging stand as claimed in claim 1, in which a quality assurance integrated circuit arrangement is provided in the base to validate authentic ink cartridges.
