    Abstract: For producing fine printing patterns on large serigraphical printing frames it is possible to apply an exposure through correspondingly large film areas, but it is cheaper to make use of a successive line-by-line exposure with the use of a modulated light or laser beam, which is caused to sweep across an emulsion coated printing frame surface from an oscillating deflection mirror. The beam (20), in its outermost positions, will be directed obliquely towards the surface (14), and if the latter changes its distance from the oscillating mirror (48) the exposure lines (16) will thus be correspondingly shorter or longer, whereby the printing pattern may be distorted. According to the invention this can be counteracted by the light ray being brought to pass a lense bar (56) mounted just in front of the line of exposure and adapted so as to deflect, all along the line, the light beam such that it will hit the surface perpendicularly, whereby the length or the lines will be independent of occurring distance variations. The width of the lense bar (56) should be at least twice the line width, as the invention also provides for a transverse displacement of the light beam for achieving that the latter may be delivered from a resonance oscillating goniometer mirror (48) with a high operational speed without overlappings occurring between the consecutive lines of exposure.

    Abstract: An image reader including: a scanning mechanism section for holding an imaging optical unit and a solid-state image pick-up device, and for rotating the imaging optical unit and the solid-state image pick-up device in an arbitrary direction and another direction orthogonal to that arbitrary direction respectively, so that an original image can be picked up with an arbitrary resolution while being segmented into a plurality of pieces; and a control section for driving the scanning mechanism section in accordance with the original image and for synthesizing the segmented image to produce original image data. As a result of this construction, the image reader is down-sized and does not require that the original be placed on the platen glass facedown and at a predetermined position, to dispense with the conventionally required complicated operation.

    Abstract: Apparatus, and accompanying methods, for determining appropriate sampling points located throughout a scanned microfilmed bit-mapped "data strip" in order to properly extract the values of stored data bits therefrom. Each data bit is formed of a contiguous group of one or more pixels in the data strip. Specifically, my technique involves parsing the data strip into successive vertical strips that each has successive rows of pixels, determining inter-row and inter-pixel differential intensity values for each vertical strip, and defining vertical line addresses and horizontal pixel addresses in each of the strips as a function of the pixel positions of the inter-row and inter-pixel differential intensity values associated therewith. The individual pixels in each vertical strip, which are situated at the horizontal pixel addresses and which lie on those rows in that vertical strip specified by the vertical line addresses, are sampled in order to yield sampled pixel data. All the sampled pixel data collectively represents the values of the data bits stored in the data strip. Advantageously, the line and pixel addresses will appropriately change in response to skew that occurs between the data strip and a microfilm line scanner as the data strip is being scanned and/or to changes in data bit size that occurs from one data strip to the next.

    Abstract: A hand scanner input system has a hand scanner. The scanner scans a medium having an image or images such as characters or graphic patterns. A mark is printed on this medium or on a transparent sheet to be placed on the medium. Hence, the mark is read when the scanner scans the medium. The image and mark read by the scanner are input to a data processor having a microcomputer. The microcomputer eliminates overlapping of the pieces of image data read by the scanner and the displacement of the scanning start position in accordance with the data representing the mark.

    Abstract: An image reading device includes a shooting unit, a light source unit, a shooting controller, and a combining unit. The light source unit sequentially irradiates the bound document with light from first and second irradiation positions opposing each other with respect to a first straight line orthogonal to a direction of a binding portion of the document. The shooting controller controls the shooting unit to shoot a first region positioned at the second irradiation position side on the document when the light source unit irradiates the document with light from the first irradiation position, and controls the shooting unit to shoot a second region containing a region other than the first region on the document when the light source unit irradiates the document with light from the second irradiation position. The combining unit combines a shot image of the first region and a shot image of the second region.
