  • Patent number: 7123386
    Abstract: An image reading apparatus of the present invention is provided with a driving unit for supplying a driving force to a scanner module and for supplying a driving force to an ADF. Changeover between the driving force for the scanner module and the driving force for the ADF is carried out by moving the scanner module, where the driving force of the scanner module and the driving force for the ADF are supplied from a single driving force source. A low cost member is used for the changeover of driving force transmission where the same driving force source (motor) supplies necessary driving force for a fed document reading mode and for a stationary document reading mode. This lowers a cost of the apparatus.

    Abstract: A scanning apparatus includes a housing with a flatbed. A loading glass is installed at the scan flatbed for loading a to-be-scanned document. A photoelectric sensing device is disposed in the housing for sensing the light signals corresponding to the to-be-scanned document to generate electric signals. The electric signals are transmitted through a flat cable to a motherboard. When the photoelectric sensing device shifts and the flat cable touches the bottom of the housing, the first adsorptive slice of the flat cable and the second adsorptive slice on the bottom of the housing adsorb each other. Therefore, the rubbing between the flat cable and the loading glass can be avoided and the quality of the scanning images can be improved.

  • Patent number: 7095535
    Abstract: Deformation of a second optical carriage (B) due to heat is large on a (C) side where an inverter (31) is attached and small on a (D) side. A mirror supporting portion inside the second optical carriage (B) supports the mirror at one point on the (C) side and at two points on the (D) side. An angle of the reflecting mirror (8) depends on two protrusions on the (D) side where thermal deformation is small, and the mirror is supported at one point on the (C) side where thermal deformation is large. Thus, even if an angle of the mirror supporting portion (C) changes, the angle of the reflecting mirror (8) is not affected. Therefore, a change in the angle of the reflecting mirror (8) can be controlled to be small when temperature of the second optical carriage (B) rises during a reading operation, and decrease in reading accuracy due to thermal deformation of the second optical carriage (B) can be suppressed.

  • Patent number: 7042600
    Abstract: A method of eliminating strobing in successive scan lines of an image includes determining a nominal scan line time and an associated scan line integration time for the image sensor. A nominal illumination light source output period is determined for the illumination source. In order to ensure that the scan line integration time is equivalent to an integer number of illumination source light output periods, at least one of the nominal scan line integration time and the nominal illumination source light output period is adjusted. A clock signal, derived from the pixel clock, drives both the frequency circuitry of the lamp drive circuit and the integration time of the image sensor. The present method provides a reliable means for eliminating lamp strobing independent of the relative phasing of the lamp oscillation phase with respect to the start of each scan line integration.

    Abstract: The invention provides an image reading apparatus that produces a precise image of an original document to prevent the read image from having distortion or irregular density, by driving a DC motor, which drives an image reading unit in a scanning direction, at a constant speed suitable for a document to be read. In addition, the image reading apparatus prevents position errors or misalignment at the start of the image reading, or at a restart of the image reading after the image reading is paused. A speed control circuit provides feedback to a DC motor to synchronize a time interval detected by a pulse interval detecting circuit with a time interval set by an interval setting register, so that the DC motor is operated at a constant speed. A counter counts the number of signals output from an encoder. After the speed of the DC motor is stabilized, a timing of signals output from a CCD drive unit to the image reading unit is synchronized with a timing of the signals generated by the encoder.

  • Patent number: 6924910
    Abstract: The image forming apparatus and image forming method according to the present invention have an object of outputting a latent image formed on an intermediate recording medium as a stable image when it is developed with toner on a medium such as paper or the like, to improve more the concentration of pixel values, by adding all of N pixels in N-pixel modulation and rearranging them with a screen-line position as a reference situated at the center, thereby to reduce boundaries between image portions and non-image portions in the sub-scanning direction. Specifically, to concentrate image parts of image signals of N pixels, pixel values of all consecutive pixels in the main scanning direction are added, and the pixels are rearranged with a screen-line position as a reference situated at the center, based on the addition result. If the addition result exceeds the maximum value of one pixel, the exceeding pixel is rearranged and outputted.

  • Patent number: 6922262
    Abstract: There is disclosed an image processing apparatus in which a pattern table stores a plurality of screen patterns which include a predetermined number of pattern data and have different data patterns. An in-pattern position calculator generates an in-pattern position signal indicating a position of an input image signal in the screen pattern from main and sub scanning synchronizing signals. A pattern selecting signal combining section generates a pattern selecting signal for selecting a specified pattern in the pattern table from the input image signal, combines the pattern selecting signal and the in-pattern position signal supplied from the in-pattern position calculator, and supplies an address in the pattern table. A controller reads pattern data corresponding to the address in the pattern table from the pattern table and supplies image data.

  • Patent number: 6891643
    Abstract: The imaging device divides the two-dimensional photo object into multiple sections before performing imaging, and obtains an ultra-high resolution complete image by splicing together the partial images of the photo object. To this end, in the imaging device, the area sensor is held essentially parallel to the photo object, and the imaging lens is moved such that its optical axis L draws a circle with the normal line N that passes trough the center of the area sensor 20 as the center of the circle. The imaging lens is stopped at each of the positions at which the imaging optical system optical axis that connects the center of the area sensor and the principal point of the imaging lens passes through the imaging center point of each section of the photo object, in order to perform imaging of each section of the photo object.

  • Patent number: 6844943
    Abstract: A system and method for eliminating absent or poor quality video sections from a video recording, such as a second generation of video recording. Synchronizing pulses associated with a video signal to be recorded are analyzed to determine whether a video signal is present and, further, to determine whether the video signal is not distorted (i.e., non-trick play mode). A recording device is selectively paused in response to the absence of a valid video signal or the presence of a video signal that is distorted, of poor quality or otherwise not worth recording.
