Abstract
A microform imaging apparatus comprising a chassis including a microform media support structure configured to support a microform media within a plane substantially orthogonal to a first optical axis, a fold mirror supported along the first optical axis to reflect light along a second optical axis that is angled with respect to the first optical axis, a lens supported along one of the first and second optical axis, an area sensor supported along the second optical axis, a first adjuster for moving the area sensor along at least a portion of the second optical axis and a second adjuster for moving the lens along at least a portion of the one of the first and second optical axis.

A digital microform imaging apparatus, comprising:
- a chassis including a microform media support structure configured to support a microform media within a plane substantially orthogonal to a first optical axis;
- a fold mirror supported along the first optical axis to reflect light along a second optical axis that is angled with respect to the first optical axis;
- a lens supported along one of the first and second optical axis;
- an area sensor supported along the second optical axis;
- a first adjuster for moving the area sensor along at least a portion of the second optical axis;
- and
- a second adjuster for moving the lens along at least a portion of the one of the first and second optical axis.
A digital microform imaging apparatus, comprising:
- a chassis including a microform media support structure configured to support a microform media;
- an illumination source supported by the chassis and directing light toward the microform media supported by the support structure to generate an image of the microform media that is projected along an optical axis;
- and
- an area sensor supported along the optical axis to sense the projected image, the area sensor supported for rotation about an axis parallel to the optical axis.

- a first adjuster for moving the area sensor along at least a portion of the optical axis;
- and
- a second adjuster for moving the lens along at least a portion of the optical axis;
- and
- a controller for controlling the first and second adjusters to simultaneously reposition the lens and area sensor to affect a change in magnification while maintaining continuous focus thereby avoiding the need to iteratively refocus at the end of a magnification change.
