The cellulose and the cationizing agent are allowed to react with each other in step 2 or step 4.
Abstract:
Disclosed is a resin material for optical purposes, which has high light permeability and high refractive index stability against temperature variation. Also disclosed is an optical element utilizing the resin material. The resin material for optical purposes comprises a curable resin and an inorganic microparticle comprising two or more metal oxides having different refractive indexes and dispersed in the curable resin, wherein the inorganic microparticle has a refractive index distribution, has the surface treated with a surface-treating agent, and is at least partially modified with a surface-modifying agent having a polymerizable functional group, and wherein the refractive index of the curable resin after being cured (nh) and the refractive index of the inorganic microparticle (ng) meet the requirement represented by the formula (1).
Abstract:
An image forming apparatus includes an image forming unit for forming images onto sheets in either one of a first mode for sequentially forming the images onto the sheets from a last page and a second mode for sequentially forming the images onto the sheets from a front page. The apparatus also includes a rotation processing unit for rotating the image in the direction of 180.degree. for the direction of the image in the first mode before the image forming unit forms the images in the second mode. The apparatus further includes a tray for stacking the sheets, a reversing path for reversing the sheet in the second mode, a conveying path for conveying the sheets formed with the images by the image forming unit to the tray directly or through the reversing path, and a stapler for performing a stapling on an upstream side in the conveying direction in the sheet and on a left side or a right side in the conveying direction. The stapler performs the stapling on the left side in the conveying direction in the first mode and on the right side in the conveying direction in the second mode.
Abstract:
A pair of vertical guide rails of a workpiece transporting system are comprised of upper and lower rail portions, the upper rail portions being movable into axial alignment with the lower rail portions, the upper and lower rail portions being supported from a ceiling member of a building, and thus movable in unison with each other in the event of movement of the ceiling member of the building. A joint between the upper and lower rail portions of one guide rail is arranged at a vertical height different from that of the joint between the upper and lower rail portions of the other guide rail.
Abstract:
An image forming apparatus includes an image forming station for forming an image on a sheet; a rotatable member for transferring the sheet in a first direction toward the image forming station; supporting device for supporting the rotatable member for displacement in a second direction which crosses the first direction; driving device for displacing the rotatable member in the second direction to correct deviation of the sheet in the second direction; and inlet guide for guiding the sheet to the rotatable member, the guide being displaceable in the second direction together with the rotatable member.
Abstract:
An image forming apparatus capable of reproducing in different colors a plurality of image areas selected from a plurality of different originals on a single copy sheet.The apparatus comprises a transparent original holder device on which is placed an original in such a way that the image bearing surface of said original faces downwardly; a first original placement reference indicating device disposed on the transparent original holder device; an original pressure device which is movable between a first position at which the original pressure device covers the transparent original holder device and a second position at which the original pressure device opens the transparent original holder device; an image area designation device which is disposed on the surface of the original pressure device and on which is placed an original with the image bearing surface thereof faced upwardly so as to designate an image area to be copied of the original; a second original placement reference indicating device which is disposed on the surface of the original pressure device and is provided for the image area designation device; and a scanning device for exposing and scanning the original placed on the transparent original holder.
Abstract:
An image forming apparatus includes an image forming unit for forming images on sheets in the copy mode, the facsimile mode, and the printer mode a plurality of storage units for storing the sheets on which images are formed by the image forming unit, a setting unit for setting storage units which are to store sheets on which images are formed in the respective modes, a detection unit for detecting empty states of the storage units, and a control unit for storing sheets on which images are formed in the facsimile or printer mode in the storage units that are set by the setting unit, and storing sheets on which images are formed in the copy mode in storage units whose empty states are detected by the detection unit independently of the setting state of the setting unit.
Abstract:
A copying apparatus includes an original feed unit for feeding originals stacked on the stacking position to an exposure position one by one, an exposure unit for exposing an image on the original fed to the exposure position, and an image forming unit for forming the image exposed by the exposure unit onto a sheet, the image forming unit being able to operate in a first mode for forming an image on a single original on a single sheet, and a second mode for forming images on a plurality of originals on a single sheet. The original feed unit includes a first feed unit for feeding the originals stacked at the stacking position in turn from the last page, and a second feed unit for feeding the originals stacked at the stacking position in turn from the first page. When the image forming unit operates in the first mode, the first feed unit feeds the originals. When the image forming unit operates in the second mode, the second feed unit feeds the originals.
