20080217414Flexible display member and article having the same - A flexible display member includes a base member having flexibility and a thin film LED (Light Emitting Diode) mounted on the base member. Accordingly, when the flexible display member is deformed, it is difficult to damage the flexible display member, thereby obtaining the flexible display member with high reliability.09-11-2008
20090051993Optical scanning projector apparatus - An optical scanning projector apparatus includes a light emitting element array having a plurality of light emitting elements arranged in a row in a first direction for emitting light according to display data; a light scanning unit for scanning light of the light emitting elements in a second direction perpendicular to the first direction; a scanning optical system for collecting light of the light emitting elements to form an image on a screen; and a control unit for controlling the light scanning unit and the scanning optical system. The light emitting elements include micro resonator type light emitting diodes (LED) having a radiation angle smaller than or equal to 20 degrees at a half of maximum light intensity.02-26-2009
20090202278Image forming apparatus - An image forming apparatus includes an image supporting member; a developing belt for supporting and transporting developer to develop a static latent image formed on the image supporting member; a developer supply member disposed to abut against the developing belt to form a specific nip portion for supplying the developer to the developing belt; a first voltage applying member for applying a first voltage to the developing belt at a first position; a second voltage applying member for applying a second voltage to the developing belt at a second position; and a third voltage applying member for applying a third voltage to the developer supply member. It is configured such that the developer supply member abuts against the developing belt between the first position and the second position.08-13-2009
20090322741THREE-DIMENSIONAL DISPLAY DEVICE, IMAGE PRODUCING DEVICE AND IMAGE DISPLAY SYSTEM - A three-dimensional display device comprises pixel blocks where pixels having a plurality of dots are arranged to be matrix, respectively, a display body formed in a matter that the pixel blocks are arranged in a matrix, lens blocks where a plurality of lenses are arranged to be matrix corresponding to the pixels, respectively, and a lens panel formed in a manner that the lens blocks are arranged in a matrix. A three-dimensional image is displayed by maintaining the display body and the lens panel at predetermined intervals so as to correspond the arrangement positions of the pixel blocks with those of the lens blocks on the matrix, concurrently, and by spatially matching virtual images of the dots, the virtual images being produced by a plurality of the lenses whose arrangement positions are the same among a plurality of the lens blocks.12-31-2009
20100073772Lens array unit, optical head and information processing apparatus - A lens array unit includes first and second lens array plates that oppose each other on opposite sides of a support member. Each of the lens array plates supports a set of lenses that are arranged in one direction and that have optical axes extending in a direction perpendicular to the one direction. The bending rigidity of the support member in the direction that the optical axes extend is higher than the bending rigidity of the first lens array plate in that direction.03-25-2010
20100073780Lens array unit, optical head and information processing apparatus - A lens array unit includes first lens array plates, second lens array plates and a support member. Each of the first lens array plate has multiple first lenses thereon. Each of the first lenses has a first optical axis that extends in a first direction and the first lenses are arranged in a second direction perpendicular to the first. Each of the second lens array plates has multiple second lenses thereon. Each of the second lenses has a second optical axis that extends in the first direction and the second lenses are arranged in the second. The support member has opposite first and second sides. The support member extends in the second direction to support the first lens array plates on the first side and support the second lens array plates on a second side so that each of the first lens array plates opposes a different corresponding one of the second lens array plates. The first lens array plates are arranged on the first side of the support member in the second direction and the second lens array plates are arranged on the second side of the support member in the second direction.03-25-2010
20100134894Lens array unit, optical head and information apparatus - A lens array unit focuses the light emitted from light emitting elements on the photoconductive drum. A longitudinally extending lens array includes a plurality of lenses and projections. The lenses are aligned in a row substantially perpendicular to optical axes of the lenses. The projections are disposed on both sides of the row, and extend outwardly further than the lens surfaces to protect the lens surfaces of the plurality of lenses. A light shielding member includes a mounting portion that holds the lens plate and a light shielding portion that shields part light passing through the lenses.06-03-2010
