Abstract: Scanners disclosed in the present invention uses a dual-illumination system comprising a front illumination source and a back illumination source. The front illumination source is controlled to illuminate a scanning object when the scanning object is opaque. The back illumination illuminates a scanning object when the scanning object is transparent. An optical system collects lights reflected from the opaque scanning object illuminate by the front illumination source or transmitted through the transparent scanning object illuminated by the back illumination source and focuses the lights upon an image sensor, thereby an image of either the opaque scanning object or the transparent scanning object can be obtained.

The platen includes a first, black portion located under the original and a second, white portion located outside the original. The widths of the first and second portions are automatically changed. The platen is formed by an endless belt having a triangular black region and a complementary white region. The endless belt is moved so that the width of the triangular black region at the reading position corresponds to the width of the original. The platen is alternatively formed as a box-shaped member or of liquid crystal panel.

Abstract: An imaging device has an optical scanning unit movably housed in a housing below a transparent document support for optically scanning a document placed on the transparent document support. The transparent document support can selectively be covered with a cover hinged to the housing. A semitransparently opalescent diffusion plate is mounted on the cover in facing relationship to the transparent document support. The cover houses a lamp unit for emitting light through the diffusion plate toward the transparent document support to irradiate the document placed thereon. A reflective document placed on the document support is irradiated by light emitted from the optical scanning unit. A reflected optical document image is applied through the optical scanning unit to an image sensor. A transmissive document placed on the document support is irradiated by light emitted from the lamp unit in the cover, and a transmitted optical document image is applied through the optical scanning unit to the image sensor. The lamp unit has lock mechanism for locking the lamp unit against movement in the cover when desired.

Abstract: An image reading method and apparatus are capable of high-quality reading of a transparent original with an optimum light quantity by maintaining both a transmitting light source unit and a reading scanner at an adequate relative position to keep their optical axes in alignment during scan reading. Such alignment is achieved by providing synchronization in scanning speed by placing either one of the transmitting light source unit and the reading scanner at an arbitrary selected position, scanning the proximity of the selected position with the other, determining a light quantity distribution, determining a synchronous position from the distribution, carrying out such synchronous position detection at two or more distinct positions, and calculating the scanning speed ratio of the transmitting light source unit to the reading scanner from the result. Alternatively, alignment is achieved by carrying out similar synchronous position detection, determining the relative spacing between the base points of said transmitting light source and said reading scanner from the distances from the respective base points to the synchronous position, and matching the scan start positions of the transmitting light source unit and the reading scanner in accordance with the relative spacing.
