    Abstract: A full-zone optical image addressing apparatus, including an addressing device, an image extraction converter, a comparator, an AND gate and a counter. The addressing device is located at the enclosure of the scanner and includes a plurality of geometric patterns. Each of the geometric patterns includes a plurality of rows of pixels. While receiving an exposure signal, the image extraction converter extracts one row of pixels from the addressing device, such that a series of analog signals is obtained and output to the comparator. The comparator then compares the series of analog signals to an analog critical voltage to output a series of analog comparison signals to the AND gate. The AND gate synchronously processes the series of analog comparison signals and a pixel rate clock to output the pixel data corresponding to the extracted row of pixels to the counter. After receiving the synchronously processed pixel value from the AND gate, the counter calculates and outputs the extracted row of pixels, including the amount of pixels and the geometric patterns in the row of pixels.

    Abstract: An apparatus for positioning a scanning starting point of an image scanning apparatus includes a platen, carriage, and a number of marks. The X-Y coordinate system defined by the platen has an X-axis defined by a first wide margin of the platen and a Y-axis defined by a first long margin of the platen. The carriage moves along the Y direction. The marks inside the image scanning apparatus indicate different Y coordinate values. The method for positioning a scanning starting point of an image scanning apparatus is as follows: the nearest mark to the document to be scanned is first chosen as a reference point. The vector from an image starting point of the document to be scanned to the reference point is then obtained. The carriage finally moves to the reference point chosen as a starting point and proceeds to scan.

    Abstract: An image reading apparatus for reading by an image sensing element an original held by an original holder while performing pixel shifting operation detects the feature point of the original holder, specifies the original position on the basis of the detected feature point, and performs the first reading of the original. After reading, the apparatus shifts the relative positions of the optical image of the original and the image sensing element by a predetermined amount. Then, the apparatus detects the feature point of the original holder again, specifies the original position on the basis of the detected feature point, and performs the second reading of the original. The apparatus synthesizes the two read original images to generate one image.

    Abstract: The objective of this invention is to provide an apparatus which can form a high-quality image by reliably adjusting the superposing positions of frame images when a single image is formed by superposing a plurality of frame images, and especially, the objective of this invention is to reliably adjust the superposing positions of frame images and form a high-quality image by controlling a rotary polygon and image carrier to operate in association with each other. To achieve such objectives, the apparatus of this invention generates a first signal indicating that the light beam coming from the rotary polygon has scanned a predetermined position, also generates a second signal independently of that detection, and moves the image carrier by selectively using the first and second signals as needed. In this apparatus, by rotating a driving means N times on the basis of a reference signal obtained by frequency-dividing the first signal, the image carrier completes one rotation. During this interval, M first signals are generated. When X signals indicating the rotation timings upon one rotation of the driving means are generated, the frequency division ratio is given by n=N×X/M.

    Abstract: An optical ruler is provided on the back surface side of the top housing and close to the transparent window along a scanning direction for providing a calibration reference. The optical ruler is formed with black and white blocks alternately arranged in an array. An image sensor which has a width larger than the width of the transparent window is provided for reading the image information of the optical ruler along with a scanned sheet while being progressively driven by a step motor. A determining element computes the actual moving steps of the step motor by calculating the number of black and white pixels from the scanned image of the optical ruler. When the actual moving steps of the step motor are fewer than a predetermined threshold value, or when the frequency of the occurrences of the scan line losses is higher than a predetermined threshold value, the image sensor is driven by the step motor to scan the sheet again. As a result, the step motor can be operated in response to a closed loop control signal depending on the actual moving steps of the step motor.
