    Abstract: In order to shorten a time for preliminary original reading which is performed prior to reading of an original image, an image reading apparatus of the present invention scans an original mounted on a platen glass by a scan optical system that moves to the original and reads a scanned image of the original by using a CCD sensor, the apparatus having a function to perform a preliminary original read operation for automatically deciding a density of the original before the reading operation of the original image, wherein the preliminary original reading is performed while the scan optical system in an idling state is moving from a read standby position to an image read operation start position; a white background level correction operation of the CDD sensor is performed after collection of original density data by the preliminary original read operation; and a result of the correction is reflected on the original density data obtained by the preliminary original reading to control the decision of the original density.

    Abstract: The invention provides an image forming method and apparatus capable of forming an image with a desired shape at a correct position on a recording medium having expansion and contraction properties. Boundary lines formed on the recording medium being conveyed are detected by a sensor. Distortion of the recording medium is evaluated on the basis of the detected boundary lines. Image data is corrected in accordance with the result of the evaluation and an image is formed in accordance with the corrected image data. In the above process, image data within the respective areas surrounded by the boundary lines is deformed such that the image is printed at a correct location even when the recording medium has distortion due to expansion/contraction.

    Abstract: A scanning device which will take samples from different positions to increase its resolution. The scanning device comprises a housing, a scanning module, and a driving device. The housing comprises a transparent platform installed on its top for placing a document. The scanning module is installed inside the housing and is slidable along a front-and-rear direction for scanning the document. The scanning module comprises a carrier, a sensor, and a positioning device for fixing the sensor inside the carrier. The sensor is installed within the carrier, is slidable along a left-right direction and comprises a plurality of linearly arranged sensing units for taking samples from the scanned document. A driving device is used for driving the scanning module forward and backward to scan the document. When the scanning module scans the document along the front-and-rear direction, the positioning device can fix the set of sensing units of the sensor at non-repeating sampling positions inside the carrier to increase the resolution of the sensor.

    Abstract: A print head, formed with spaced linear subheads of jet nozzles, prints all of the lines or image element rows on a print medium such as a sheet of paper by scanning along the face of the sheet. The head is advanced between scans by an equivalent number of lines generally equal to the number of nozzles in the head, whereby all print lines are addressed only once. Apparatus for printing includes the use of pointers in registers to keep track of head structure and location on a print medium for calculating print addresses. A partial page memory is used which wraps around to the beginning from the end. An edge sequence control logic circuit modifies the print data so that nozzles not over the image area do not print. A positive printer carriage position encoder uses an index marker located in the middle of a strip of incremental markers. Sensing of the index marker resets an up/down counter with a value that gives a positive value for all count conditions.

    Abstract: Print heads are formed with spaced subheads having nozzles such that all of the lines or pixel rows on a print medium such as a sheet of paper are printed by scanning of the print head along the face of the sheet. The head structures include three subheads, each having nozzles for printing one or more adjacent lines with the subheads being spaced the same number of lines apart as the number of lines each prints; and three subheads spaced the equivalent of seven lines apart, each subhead having three nozzles spaced at the equivalent of alternate lines. The heads are advanced between scans by an equivalent number of lines generally equal to the number of nozzles in the head, whereby all print lines are addressed only once. Apparatus for printing includes the use of pointers in registers to keep track of head structure and location on a print medium for calculating print addresses. A partial page memory is used which wraps around to the beginning from the end. A positive printer carriage position encoder uses an index marker located in the middle of a strip of incremental markers.

    Abstract: A dot-matrix pinter is adapted to include an optical scanner for opto-electrically sensing the optical intensity levels of an image-bearing medium in order to provide a digitized representation of the image. The sensor can be mounted on a housing in the printer for continuous linear movement across the image while the sensor is scanning. Sampling means responsive to the printer strobe command signal is provided for sampling the output of the sensor at predetermined intervals. This output is loaded line by line into a memory buffer. Means for processing the sampled output of the sensor into a form compatible with a dot-matrix printer is also provided. A method of generating a digitized representation of an image using a dot-matrix printer adapted to include an optical scanner for optoelectrically scanning the optical intensity levels of an image-bearing medium is also provided. The representation can have either bilevel or gray-scale quality. In the case of gray-scale quality, the representation of the original image has more than one pixel space for containing dots corresponding to each sampled pixel in the original image whereby gray-scale resolution is provided by the distribution of dots in the reproduced image.
