Abstract: A copier including a printing unit and a detachable image scanner that is physically detachable from the printing unit and communicably connectable to the printing unit. The image scanner includes a substrate; a microprocessor mounted on the substrate; a digital camera module mounted on the substrate and connected to the microprocessor; and a light-emitting diode (LED) array mounted on the substrate and connected to the microprocessor. The image scanner is configured to illuminate an object to be scanned with the LED array and image the object to be scanned with the digital camera module to produce an image signal that is then transmitted to a central processing unit (CPU) through the microprocessor and from the CPU to the printing unit for output as a printed copy.

Abstract: An imaging module unit fixedly mounted on top of a copier within a document contact area where a document contacts a top surface of the copier. The imaging module unit has a digital signal processor (DSP) chip mounted a base plate, an imaging module mounted on the base plate, and a light-emitting diode mounted on the base plate. The imaging module unit directs light from the LED onto the document, images the contents of the document with the imaging module, and, through the DSP chip, automatically adjusts output.
