Patent ID: 7073715

Claim:
An interface assembly for interfacing an imaging engine removably positioned within an optical code reader and having an adjustable lens assembly to a circuitry assembly of an optical code reader system, the interface assembly comprising: a first coupling circuitry assembly for transmission of at least one input signal including in a first direction from the circuitry assembly toward the imaging engine, the at least one input signal including at least one focus control signal for controlling the lens assembly for selecting a focus position of at least two focus positions, a focus control motor power signal, an illumination power signal, a combined CCD/aiming power signal, an illumination enable signal for controlling an illumination assembly of the imaging engine and an aim enable signal for controlling an aiming assembly of the imaging engine, wherein the at least one focus control signal includes two signals for selecting a focus control mode from at least three focus control modes, and wherein the at least three focus control modes are selected from the group of focus control modes consisting of a first mode for operating a motor of the lens assembly for selecting a first focus distance, operating the motor for selecting a second focus distance, not operating the motor and not selecting a focus distance, and operating the motor to switch between the first and second focus distances for image acquisition of a series of at least two image acquisitions; and a second coupling circuitry assembly for transmission of at least one output signal in a second direction from the imaging engine toward the circuitry assembly, the at least one output signal including at least one pixel data signal, wherein the at least one pixel data signal is indicative of light sensed by a photo sensor array of the imaging engine.
