Abstract: A light emitting module includes a light emitting unit including a plurality of light sources, a reflection unit disposed on the light emitting unit and configured to reflect light emitted from the light emitting unit, and a lens unit disposed on an optical path of the light reflected by the reflection unit. The reflection unit includes a plurality of reflection holes corresponding to the plurality of light sources and having inner walls which are provided as reflective surfaces. A depth of a reflection hole distant from an optical axis of the lens unit is greater than a depth of a reflection hole adjacent to the optical axis of the lens unit.

Abstract: Provided is a light emitting diode (LED) device. The LED device may include an LED, a body on which the LED is fixed and a coil is wound, and a magnet that is located at a predetermined distance from the coil, on at least one side of the body, and that provides a magnetic force to the coil, and the body may move in a predetermined direction when a voltage is provided to the coil.

Abstract: An image reading apparatus, a method of controlling the same, and an image forming apparatus including the same are disclosed. The image reading apparatus may pre-recognize performances of even-pixel and odd-pixel groups for each color in an image sensor including an even-pixel group and an odd-pixel group for each color. In case of reading an image using only one of the above pixel groups, the image reading apparatus may read the image using a superior-performance pixel group selected from the above pixel groups, such that a signal-to-noise ratio (SNR) may be reduced and image processing may be more quickly carried out.

Abstract: A method and apparatus for scanning an image. The method includes determining whether the brightness of light sensed in the image input sensor is within a predetermined brightness range, if it is determined that the brightness of light is not within the predetermined brightness range, then the cover of the image forming apparatus is open and then closed, and image scanning is performed. However, if it is determined that the brightness of light is within the predetermined brightness range, the cover of the image forming apparatus is closed, and the image forming apparatus remains in an initialization state.

Abstract: A device and a method for using a temperature detector to detect heat generated from the lamp of a scanning device to prevent the operation of a scanner while the scanner is overheating. Thus, effectively preventing the degradation of a scanner due to the overheating of the lamp in the scanning device of a multi-function peripheral. In addition, when the lamp becomes overheated, a safety margin can be maintained even when the central processing unit is not operating properly, because the power of the lamp gets cut off compulsorily through hardware rather than software that is necessarily dependent on the central processing unit.

Abstract: A sheet-size-determining device in a scanner, includes: a sheet carrier, having a pattern formed across the entire surface thereof, for holding (loading) a sheet of printed medium; a paper feeding device for controlling the feeding operation of the sheet carrier; a shuttle scanner module for scanning image data of the sheet of printed medium and outputting the scanned image data; a carriage return motor for driving the shuttle scanner module; an image memory for temporarily storing the scanned image data output from the shuttle scanner module; and a controller for analyzing the temporarily stored image data and outputs a control signal to the carriage return motor according to the analysis. The sheet carrier includes a background panel having a pattern formed thereon and a transparent flap connected to the background panel along one edge thereof.

Abstract: A deviation correcting system for a scanner including a central processing unit producing a control signal for reading out a correcting program for correcting a scanning deviation, and a test pattern, for printing the test pattern, for scanning the printed test pattern, and then for correcting a scanning deviation; a print driver producing a control signal for printing the test pattern produced from the central processing unit, feeding the test pattern back to a scanning position; a printing unit printing the test pattern and then feeding the test pattern back to the scanning position upon application of the control signal from the print driver; an image processing unit producing a control signal for scanning the test pattern upon application of the control signal from the central processing unit; and a shuttle scanner module scanning the test pattern and producing image data upon application of the control signal from the image processing unit.
