Abstract
Systems and methods use a digital microform imaging apparatus for sensing an image mark on the microform containing the image of a document.
Claims26
A method for sensing an image mark on a microform using a digital microform imaging apparatus, the apparatus having an area sensor, the method comprising the steps of:
- defining an image mark region of interest within a pixel array of the area sensor, the pixel array having a predefined number of pixels and the image mark region of interest having a predefined number of pixels less than the predefined number of pixels in the pixel array;
- sensing at least one image mark on the microform using the image mark region of interest;
- and
- sensing an image on the microform using the area sensor.
A film guide assembly for retaining a microform media on a digital microform imaging apparatus, the film guide assembly comprising:
- a frame;
- an outside roller assembly supported by the frame;
- a middle roller assembly supported by the frame;
- and
- an inside roller assembly supported by the frame;
- the outside, middle, and inside roller assemblies forming a film transport path, and wherein at least two of the outside, middle, and inside roller assemblies form a film slot to load the microform media into the film guide assembly, the film slot being partially defined by a shelf coupled to the frame.
A media support lock assembly for retaining a microform media support on a digital microform imaging apparatus, the media support lock assembly comprising:
- a body;
- an adjuster threadably positioned within the body;
- and
- a magnet coupled to one end of the adjuster.
A media support lock assembly for retaining a microform media support on a digital microform imaging apparatus, the media support lock assembly comprising:
- a body to couple to a shaft of the microform media support;
- and
- an adjustable magnet coupled to the body.
A digital microform imaging apparatus, the apparatus comprising:
- an area sensor;
- a film guide assembly for retaining the microform on a film path, the film path including an optical path;
- a microform support for retaining the microform on the film path;
- and
- a media support lock assembly including a magnet for magnetically retaining the microform media support in a predefined position on the digital microform imaging apparatus.
