20090167837 | IMAGE FORMING APPARATUS - An image forming apparatus includes an optical scanning device that scans a scan area on an image carrier with light flux containing image information and writes the image information onto an image area in the scan area. In the optical scanning device, a first light receiving unit receives light flux emitted from a light source and reflected by a reflecting optical unit; a second light receiving unit receives light flux that passes through an aperture of the reflecting optical unit, is deflected by a deflecting unit, and heads for outside the image area within the scan area; and a control unit controls a drive signal of the light source based on signals output from the first and second light receiving units. | 07-02-2009 |
20100103239 | OPTICAL SCANNER UNIT AND IMAGE FORMING APPARATUS - An optical scanner unit includes an LD unit, a polygon mirror deflecting a light beam, an optical scan system focusing the light beam from the polygon mirror on a photoconductive drum to form an electrostatic latent image, and a synchronous detector receiving a part of the light beam to detect a write start position on the photoconductive drum in main scan direction. The synchronous detector is fixed on a portion of a housing at predetermined angles in main and sub scan directions relative to an incidence angle of the light beam on the synchronous detector. | 04-29-2010 |
20100157012 | IMAGE PROCESSING MATCHING POSITION AND IMAGE - An apparatus includes: a position detection section which detects the position of the apparatus at predetermined detection timing; a light source section which emits light at light emitting timing synchronized with the detection timing; an image-taking section which takes the image of a photographic subject by using the emitted light; and an image processing section which matches the position data indicating the detected position of the apparatus and the image data obtained by the image-taking. | 06-24-2010 |
20130222513 | OPTICAL SCANNING DEVICE AND IMAGE FORMING APPARATUS INCLUDING THE SAME - An optical scanning apparatus includes a reflecting mechanism, a light receiving element and a restricting mechanism. The reflecting mechanism reflects a light beam such that the irradiation point of the light beam moves in a predetermined scanning direction. The light receiving element is arranged in a movement plane defined by the light beam reflected by the reflecting mechanism, and the light receiving element outputs a light reception signal for adjusting the irradiation timing of the light beam in accordance with reception of the light beam reflected by the reflecting mechanism. The restricting mechanism positions the light receiving element relative to the movement plane. | 08-29-2013 |
20140292994 | COLLECTIVE MARKING OF A SURFACE BY STEERING MULTIPLE LASER BEAMS GENERATED BY A LASER CONTROLLER - Disclosed are methods, systems, and/or apparatus for the collective marking of a surface by two or more laser beams generated by a laser controller. A method includes receiving one or more input signals from a controller of the laser system. The method also includes adjusting a first mirror through a first galvanometer scanner, a second minor through a second galvanometer scanner, a third mirror through a third galvanometer scanner, and a fourth mirror through a fourth galvanometer scanner based on the one or more input signals. The method further includes steering, through the first mirror and the second mirror, a first laser beam generated by the controller and transmitted to a marking head through a beam delivery vessel; and steering, through the third mirror and the fourth minor, a second laser beam generated by the controller and transmitted to the marking head through another beam delivery vessel. | 10-02-2014 |
20140354756 | OPTICAL SCANNING DEVICE AND IMAGE FORMING APPARATUS THEREWITH - An optical scanning device has a light deflector deflecting a light beam from a light source, a synchronization detection sensor determining timing of starting scanning in main scanning direction based on timing of detecting the light beam scanned in main scanning direction by the light deflector, and a pre-sensor imaging optical system imaging the light beam reflected from the light deflector on the synchronization detection sensor. The pre-sensor imaging optical system moves the imaging position of the light beam on the synchronization detection sensor in a direction making the timing of detecting the light beam earlier or later according to whether variation in temperature causes the magnification of the scanning optical system in main scanning direction to increase or decrease respectively. | 12-04-2014 |
20150049154 | DRAWING CONTROL METHOD, LASER IRRADIATING APPARATUS, DRAWING CONTROL PROGRAM, AND RECORDING MEDIUM HAVING RECORDED THEREWITH - Drawing control methods, laser irradiating apparatuses, drawing control programs, and recording mediums having recorded therewith are provided that make it possible to efficiently carry out drawing with high quality. The drawing control method controls, by a computer, a drawing device which draws what is to be drawn onto multiple unit regions on a surface of a medium. The computer executes a drawing order determining step which determines a drawing order of a line segment included in the what is to be drawn such that multiple continuing line segments over mutually neighboring multiple unit regions are drawn continuously. | 02-19-2015 |
