| 20080296825 | SHEET PROCESSING APPARATUS AND IMAGE FORMING APPARATUS - The invention is to provide a miniaturized sheet processing apparatus in that a conveying length a conveying distance need not be increased even though the number of sheets per bundle increases. A glue applying bookbinder that partially glues sheets and performs a pressing process to form a sheet bundle. The glue applying bookbinder includes a processing tray that stacks sheets, a glue applying portion that applies a glue on the sheets on the processing tray, and pressing portions that press the sheets on the processing tray. The glue applying portion is arranged such that the glue applying portion can be moved from a first standby position outside the sheets stacked on the stacking portion to a second standby position, different from the first standby position, outside the sheets through an upper surface of the sheets, and the pressing portions are moved integrally with the glue applying portion. | 12-04-2008 |

| 20090190211 | OPTICAL DIFFUSING SHEET, OPTICAL DEFLECTING SHEET, AND TRANSMISSION TYPE SCREEN - An optical diffusing sheet is provided, which prevents deterioration in image quality which might result from warping of the sheets due to environmental changes, and is capable of, even if a substrate is broken by an accident, preventing scattering of pieces of the broken substrate. An optical diffusing sheet is used in a transmission type screen that emits imaging light projected from an incident side to an emergent side. The optical diffusing sheet includes a highly rigid substrate layer with a light-transmissibility and a high rigidity, and a plurality of layers laminated on the highly rigid substrate layer. The plurality of layers includes at least a pair of anti-scattering layers disposed on opposite sides of the highly rigid substrate layer for preventing scattering of the highly rigid substrate layer. At least one layer of the two or more layers includes an optical diffusing element that diffuses imaging light. | 07-30-2009 |
| 20100195020 | LIGHT CONTROL SHEET, SURFACE LIGHT SOURCE DEVICE, AND TRANSMISSION-TYPE DISPLAY DEVICE - A light control sheet, used in a surface light source device having a light source to control a travel direction of light emitted from the light source, including: a base layer; a lens layer having unit lenses arranged on the light outgoing side of the base layer; a light selection layer disposed on the light incident side of the base layer and a light selection layer disposed on the light incident side of the base layer and having light transmission parts transmitting the light therethrough and the light reflection parts reflecting the light; and a support layer disposed on the light incident side of the light selection layer. Each light transmission part is disposed in a region including a position opposite to an apex of each corresponding unit lens in a normal direction to the sheet surface. The light reflection parts are respectively arranged alternately to the transmission parts. | 08-05-2010 |
| 20100246161 | OPTICAL SHEET, SURFACE LIGHT SOURCE DEVICE, AND TRANSMISSION DISPLAY DEVICE - An optical sheet is incorporated in a direct type surface light source device including a light source and is configured to allow light emitted from the light source to exit after changing a travel direction of the light. The optical sheet has a light exiting side lens part including unit lenses juxtaposed to one another and each unit lens is convex toward a light exiting side. A light scattering layer, configured to scatter the light, is provided to each unit lens. The light scattering layer extends along a light exiting side surface of each convex unit lens and constitutes the light exiting side surface of the unit lens. A thickness of the light scattering layer around an apex portion of each unit lens is greater than the thickness of the light scattering layer around each end portion of the unit lens. | 09-30-2010 |
