主权项

1. A focus assembly for a magnification device, the assembly comprising:
a housing with front and rear surfaces, a display screen within the front surface, a camera opening within the rear surface, the housing being pivotally connected to a handle, the housing and handle having a number of discrete orientations, including a first orientation wherein the handle is folded against the rear surface of the housing; a CMOS sensor and a lens positioned within the housing, the CMOS sensor and lens being in registry with the camera opening, the distance between the CMOS sensor and lens constituting a focus distance; a pivotal clevis assembly positioned within the housing, the clevis having forward and rearward ends and a pivot point therebetween, the clevis having a pivotal range of movement, a biased actuator positioned at the rearward end of the clevis, the actuator having a distal end that extends through a surface of the housing, a lens cradle interconnected to the forward end of the clevis, the lens positioned within the lens cradle, an adjustment screw positioned within the rearward end of the clevis for selectively adjusting the pivotal range of movement; whereby when the housing and handle are in the first orientation the actuator is depressed and the clevis is pivoted such that the lens moves towards the camera opening.
