20090009581 | PRINT UNIT - A print unit for transferring an image to a photosensitive medium is provided, and the print unit includes an intercepting member for intercepting light; a first plane light-emitting member for forming a first image by emitting light, provided on one side of the intercepting member; a second plane light-emitting member for forming a second image by emitting light, provided on the other side of the intercepting member; and a control unit for controlling light-emission of the first and second surface emitting members and transferring at least one or more of images to the photosensitive medium. | 01-08-2009 |
20090066780 | Image forming apparatus, optical writing device, and optical writing method - An image forming apparatus includes a plurality of image carriers and an optical writing device including light sources that emit light beams of different wavelengths, a deflector that deflects the light beams emitted from the light sources and synthesized on an identical axis in a sub-scanning direction, a first beam separator, a second beam separator, a first imaging device, and a second imaging device. The first beam separator and the second beam separator are located between the first imaging device and the second imaging device and transmit or reflect the light beams according to travel directions or wavelengths thereof. One of the targets is scanned with the light beam transmitted through the second beam separator. Another target is scanned with the light beam reflected by the second and first beam separators. The first and second imaging devices narrow the beams in the main scanning direction and the sub-scanning direction, respectively. | 03-12-2009 |
20090256900 | System and Method for Optical Printing on a Laser Printer - A laser printer includes a light source that is passed through or conditioned by an LCD (Liquid Crystal Display) apparatus, a DLP (Digital Light mirrors) apparatus, to filter the light source before the light beam is applied to the photosensitive drum for the purpose of dispensing toner to paper. Passing the light beam through an LCD apparatus or a DLP apparatus results in the light intensity of each dot of the printed page being controlled by the LCD apparatus or the DLP apparatus. After the light beam is passed through an LCD apparatus or a DLP apparatus, the conditioned light is applied to a photosensitive drum, causing the drum to be charged in a manner to transfer toner to the printed page. | 10-15-2009 |
20100128101 | MULTI-BEAM IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD USING THE SAME - A multi-beam image forming apparatus and a method using the same. The image forming apparatus includes: an image process module to divide first image data into a plurality of second image data; a light scanning unit to scan the plurality of second image data using a plurality of laser beams; and a controller to control the formation of an electrostatic latent image of the first image data on a photosensitive body in an overlapping manner, using at least two of the plurality of laser beams. | 05-27-2010 |
20110058010 | IMAGING HEAD FOR 3D IMAGING - An imaging head ( | 03-10-2011 |
20110199455 | INKJET PRINT ENGINE HAVING A PLURALITY OF LASER SCANNING UNITS - A printing engine, having an ink support adapted to support an amount of ink, a plurality of laser scanning units, each laser scanning unit including a laser adapted to emit a laser beam and a directing unit configured to direct the laser beam onto the ink support. The laser scanning unit is adapted to apply energy to the amount of ink at a laser beam spot position. The laser scanning units are adapted to simultaneously scan the ink support substantially in a main scanning direction with respective laser beam spot positions, the laser beam spot positions being remote from each other. | 08-18-2011 |
20120026272 | OPTICAL IMAGING SYSTEM - A method of scanning a pattern on a surface, the method comprises forming a first spatially modulated light beam including a pattern for writing on a surface; splitting the first spatially modulated light beam into a plurality of sub-beams; altering a spatial relationship between the plurality of sub-beams, thereby forming a second spatially modulated light beam; and canning the surface with the second spatially modulated light beam. | 02-02-2012 |
