Processor for a print engine assembly having power management circuitry

Abstract

Provided is a processor for a print engine assembly having a card reader for reading data from a data card. The processor includes a central processor unit having memory units, an orientation sensor, and a number of motor controllers for controlling drive motors of the print engine assembly. The processor also includes a power management circuit for managing power consumption of the print engine assembly. The processor is configured to read the data from a data card with the card reader, the data read from the card instructing the processor in a manner of processing a digital image.

1 . A processor for a print engine assembly having a card reader for reading data from a data card, said processor comprising:
 a central processor unit having memory units;   an orientation sensor;   a number of motor controllers for controlling drive motors of the print engine assembly; and   a power management circuit for managing power consumption of the print engine assembly, said processor configured to read the data from a data card with the card reader, the data read from the card instructing the processor in a manner of processing a digital image.   
     
     
         2 . The processor as claimed in  claim 1 , wherein the card reader includes:
 a light source configured to emit light onto the card;   a sensor configured to sense light reflected from the card;   focusing means for focusing the light; and   a housing for housing the light source, sensor and focusing means, the housing having an interface to interface the sensor with the processor.   
     
     
         3 . The card reader of  claim 2 , wherein the focusing means includes a translucent portion having a curved circumference to focus light emitted from the light source on the card. 
     
     
         4 . The card reader of  claim 2 , wherein the focusing means includes at least one lens in the housing for focusing the light reflected from the card on the sensor. 
     
     
         5 . The card reader of  claim 2 , wherein the sensor includes a charge coupled device (CCD) configured to supersample a surface of the card. 
     
     
         6 . The card reader of  claim 2 , wherein the light source includes at least one light emitting diode (LED). 
     
     
         7 . The card reader of  claim 2 , having a transport mechanism for transporting the card past the reader.
