| 20100046052 | ACTUATOR, OPTICAL SCANNER, AND IMAGE FORMING APPARATUS - An actuator includes: a frame; first members at each end of the frame along a first axis making the frame rotatable thereabout; second members supporting each end of a movable plate against the frame along a second axis making the movable plate rotatable thereabout; first magnets with poles interposing the first axis; a second magnet with poles interposing the first axis; a coil generating a magnetic force acting on the first and second magnets; and a voltage source applying a voltage to the coil. The first and second magnets have an angle of 30-60 degrees to the first axis, and identical magnetic pole directions. The voltage source includes first and second voltage generators generating first and second voltages of first and second frequencies, and a voltage superimposer. The movable plate is rotated about the first and second axes at the first and second frequencies by the superimposed voltages. | 02-25-2010 |
| 20100238533 | OPTICAL DEVICE, OPTICAL SCANNER, AND IMAGE FORMING APPARATUS - An optical device includes: an axis member including a plate-shaped attachment portion and an elastic support portion that swingably supports the attachment portion around a predetermined axis; a rigid member attached to one side of the attachment portion; and a light reflecting member attached to the other side of the attachment portion and having an area larger than that of the attachment portion. | 09-23-2010 |
| 20100245961 | OPTICAL DEVICE, OPTICAL SCANNER, AND IMAGE FORMING APPARATUS - An optical device includes: a movable plate disposed in an area over which externally incident light is spread, the movable plate having a light reflecting surface that reflects the light; and an axis member that swingably supports the movable plate around a predetermined axis, wherein each portion in the light spread area but other than the movable plate is formed of a surface having a normal vector along which the light is reflected and directed outside a predetermined area. | 09-30-2010 |
| 20110032589 | LIGHT DEFLECTOR, METHOD OF MANUFACTURING LIGHT DEFLECTOR, AND IMAGE DISPLAY DEVICE - A light deflector includes: a movable plate; an elastic support section having a first end coupled to the movable plate and adapted to support the movable plate rotatably around a predetermined axis; a support member coupled to a second end of the elastic support section; and a light absorbing section having a light absorbing property, wherein the elastic support section has an upper surface, a lower surface, and at least one side surfaces, each of the side surfaces being formed of one or more tilted surfaces existing outside either one of the upper surface and the lower surface, and the light absorbing section is disposed on the upper surface and the at least one side surfaces of the elastic support section. | 02-10-2011 |
| 20110102870 | LIGHT DEFLECTING ELEMENT, LIGHT DEFLECTOR, AND IMAGE FORMING DEVICE - A light deflecting element includes: a movable plate provided with a light reflecting section having light reflectivity; a support section; a coupling section adapted to couple the movable plate rotatably to the support section; and a magnet disposed on an opposite surface of the movable plate to the light reflecting section, wherein the coupling section has a shape having a width gradually increasing in a direction from a side of the light reflecting section toward a side of the magnet in a cross-sectional view perpendicular to a rotational axis of the movable plate. | 05-05-2011 |
| 20110116055 | IMAGE FORMING APPARATUS - An image forming apparatus includes: a first projector that scans light on a first display section to thereby display an image; a second projector that scans the light on a second display section, which is set in a position different from a position of the first display section, to thereby display an image; and a switching section that switches plural states including a first state in which the first projector displays the image on the first display section and a second state in which the second projector displays an image on the second display section. | 05-19-2011 |
