摘要： The heat and pressure rolls of a fusing apparatus for an electrophotographic copying machine are shifted into pressure contact with one another while a support sheet bearing a toner powder image passes therebetween, and are separated while the sheet is not therebetween. A driving mechanism drives both rolls when not in contact, while one of the rolls drives the other while in pressure contact. A shifting mechanism is actuated by a sheet detector for shifting the rolls into and out of contact.In another embodiment, the rolls are in light rolling contact, with no sheet passing therebetween, under the weight of one of the rolls idly mounted in place. A pressing mechanism presses the rolls into pressure contact, upon actuation by a sheet detector, while the sheet passes between the rolls.

摘要： An optical illumination device for use in a copying apparatus of the type wherein an object is to be illuminated and an image thereof is to be projected through a particular image transmitter formed of a plurality of optical fibers of graded refractive index in bundled configuration to a light sensitive surface, comprises a source of illumination light and a light guide duct of substantially flattened cubic body. The light guide duct is designed such that rays of light from the light source accommodated within the light guide duct are directed towards a curved reflective surface and subsequently converge at one point on the transparent support structure for the support of the original to be copied thereon to form a strip or ribbon of light available for illumination of the original to be copied.

摘要： A residual toner removing apparatus comprises a rotatable cleaning brush enclosed by a casing plate and a restriction board except for two gaps housed in a housing with an opening adjacent to a known photoreceptor surface. During rotation, brush hairs contact the casing plate to charge it with an opposite polarity to that of the toner particles, while the brush hairs are compressed by the restriction board, the cleaning brush thus acting like a fan for circulation of air and entrained toner particles, during which circulation lighter toner particles are attracted by the casing plate with heavier particles falling into catchment portions on the casing and well portions at lower parts of the housing for efficient removal of toner particles without separate vacuum means.
