Abstract:
Disclosed is an image reading apparatus capable of being switched between an observation state in which an image on a recording medium (F) is projected onto a screen (6) and observed and a read state in which the image is scan-projected onto a reading unit (59) and read, comprising a projecting lens (5) provided in a lower portion of the apparatus to project the image, a rockable first reflecting member (9) provided in an upper portion of the apparatus to reflect the image light from the projecting lens, a second reflecting member (10) provided in opposition to the screen (6) to guide the image light reflected by the first reflecting member to the screen, a third reflecting member (63) provided below the second reflecting member to guide the image light reflected by the first reflecting member to the reading unit (59), wherein the observation state and the read state are switched by the rocking motion of the first reflecting member (9). In the read state the image is scanned onto the reading unit by the rocking motion of the deflecting first reflecting member (9). The reading unit (59) includes a CCD linear array detector (60) arranged to be rotated about its longitudinal axis in synchronism with the rocking motion of the scanning member (9) so as to be oriented always perpendicularly to the incident light. The detector is moved in the direction of incident light for compensating for curved field distortion, thus improving focus condition of the scanned image.

A virtual camera control (57) at the remote location controls the camera (26) of the viewing and scanning device (44).
Abstract:
Apparatus and method of processing microfiche images. The apparatus (10) includes an unattended high-resolution line scanning station (18). The low-resolution station (14) automatically identifies active image areas and borders on a plurality of light passing documents (101) transported seriatim along a prescan path. The unattended low resolution scanning station generates a plurality of active image area signals indicative of the active image areas and borders in a plurality of light passing documents. The unattended high-resolution line scanning station includes a high-resolution line scanner that responds to the individual ones of said plurality of active image area signals.
Abstract:
A system and method for storing documents in human and machine readable format. A laser scanner is used to write de-magnified visual copies and digital records of the documents in an optical recording medium. A table of contents and record headers are provided to ease document retrieval. The optical recording medium is made of materials which can be written directly by the laser scanner without the need for post-writing processing. The direct write characteristic allows immediate retrieval, and allows additional documents to be added to the optical recording medium at later times. The documents are retrieved from the optical recording medium by either magnifying the visual copies or by regenerating the documents in visual form using the digital information.
Abstract:
A digital microform imaging apparatus, comprising a chassis, a fold mirror supported by the chassis and including a reflecting surface for directing light from a first substantially vertical optical axis to a second substantially horizontal optical axis, a microform media support structure supported at a location intersected by the first optical axis, a first carriage supported for movement along a trajectory that is substantially parallel to the second optical axis, an area sensor supported for movement along the second optical axis, the area sensor further supported by the first carriage for rotation about an axis parallel to the second optical axis and a lens supported for movement along the second optical axis, the lens positioned between the area sensor and the fold mirror, a first motor mounted to the first carriage and linked to the area sensor for rotating the area sensor between at least two positions for obtaining portrait and landscape images of a microform media.
Abstract:
A method for reading analogue and/or digital data, which are stored in fields on a microform, includes using a device for accessing the microform, which device is connected to a data processing system via a hardware interface. In order to make it possible to further process the data acquired by the device in a conventional personal computer, the analogue and/or digital data stored on the microform are represented by a control unit of the device of the data processing system as if the microform were a conventional replaceable data storage medium. Finally, the microform has a structure that allows the data stored thereon to be read quickly and is also suitable for the long-term and secure archiving of digital data.
Abstract:
This invention has as its object to obtain a high-quality read image from which dust or scratches have been removed by an image reading apparatus which reads image information on a transparent original by synchronously scanning a light source unit and image reading unit. To this end, upon reading a transparent original, infrared LED chips on a dust/scratch detection LED substrate and a transparent original illumination lamp are turned on to make alignment between the LED substrate and the image reading unit, and dust/scratch detection image information is obtained by synchronously moving the light source unit and image reading unit in the subscanning direction.Subsequently, alignment between the transparent original illumination lamp and image reading unit is made, and image information of the transparent original is obtained by synchronously moving the light source unit and image reading unit in the subscanning direction.

Abstract:
A line CCD scanner includes a photo film passageway in which developed photo film is positioned. A light source illuminates an image in the photo film positioned in the photo film passageway. A line CCD reads the image being illuminated. A mask member is secured to the photo film passageway. The image is positioned at the mask member. A mask slit is formed in the mask member, for directing light from the light source toward the photo film. The mask slit has a small width with reference to a predetermined direction. Furthermore, a protrusion portion is disposed on the mask member to extend in the width direction of the photo film, provided with the mask slit formed in a middle thereof, for flexing the photo film in the longitudinal direction to remove flexing in the width direction.
