    摘要: Expandable scanner apparatus (10) may comprise a main body (18) with a detector (26) mounted therein. A contact head (20) mounted to the main body (18) can be moved toward and away from the main body (18) between a retracted position (22') and an extended position (22). An optical system (24) operatively associated with the main body (18) and the contact head (20) focuses on the detector (26) image light (28) from an object (12) being scanned when the contact head (20) is in the extended position (22).

    摘要: A drum scanning type image reading apparatus includes an illumination optical system and an imaging optical system. The illumination optical system is an optical system for irradiating light upon an original. A variable aperture stop is disposed at a conjugate position with the original. In the imaging optical system, a pick-up lens focuses an image of an image reading region of the original on an image focusing surface, and photomultiplier tubes read light passing through one of holes which are formed in a main aperture plate which is disposed on the image focusing surface. To change an image reading resolution in the image reading apparatus, the image reading region and an illumination region are changed by changing the aperture size of the main aperture plate and the size of the variable aperture stop.

    摘要: The present invention is directed to a laser printer including a printer controller, a printhead including a plurality of lasers formed in an array for receiving modulating image data from the printer controller, a variable magnifying means such as a zoom lens, and a drum on which a receiver member is mounted on which an image is to be printed. The printer controller is arranged to selectively use any one of a set of predetermined microdot matrixing values and a separate sub-microdot matrix associated therewith, and distribute image data to the plurality of lasers based on such microdot and submicrodot matrixing values. The variable magnification means (e.g., a zoom lens) applies optical magnification or demagnification to light beams from the array of lasers to provide selective variable microdot matrixing values between the predetermined microdot matrixing values of the set. Therefore, any dot density between a low and a high microdot matrix value of the set of predetermined microdot matrixing values is produced using combinations of microdot and sub-microdot matrixing by the printer controller and variable magnification of the zoom lens.

    摘要: A system for forming optical beam spots of different sizes on an imaging surface (245), includes an emitter (205) configured to emit an optical beam along a path. The optical beam is focused at a first focus point (255) and impinges upon the imaging surface downstream of the first focus point. A lens (220), having a single fixed magnification other than one, is located between the first focus point and the imaging surface so as to be in the optical path of the optical beam. The lens is moveable between a first position located a first distance (S 1 ) from the first focus point and a second distance (S 1 ') from a second focus point (260) of the optical beam which is downstream of the lens and a second position located the second distance from the first focus point and the first distance from the second focus point. With the lens at the first position the optical beam forms a beam spot of a first size on the imaging surface and with the lens at the second position the optical beam forms a beam spot of a second size, which is different than the first beam size, on the imaging surface.

    摘要: It is determined whether the long sides of a document is parallel to the main or sub scanning direction of a scanner to set resolutions of image data along the short and long sides of the document while the image data is being facsimiled (step S6). When the long sides of the document is parallel to the main scanning direction (step S3), the scanner scans the document in the main scanning direction by the resolution along the long sides and in the sub scanning direction by the resolution along the short sides to read the image data (step S23). The image data is rotated 90 degrees (step S24), and the rotated image data is facsimiled in the A4-R direction on the ITU's advice (step S28). The image data is not degraded when it is rotated but can be transmitted in good quality.
