摘要： An automatic sheet feeder comprises a feed roller which feeds sheets stacked in a pile one by one to a sheet conveying path, a conveyor roller provided on the sheet conveying path to convey the sheet delivered to the sheet conveying path by the feed roller to an image reading unit. The sheet conveying speed of the conveyor roller is higher than the sheet feeding speed of the feed roller. A feed roller gear is mounted on a feed roller shaft fixedly supporting the feed roller thereon and is interlocked with the feed roller shaft by a one-way clutch mechanism. The clutch mechanism couples the feed roller gear with the feed roller shaft to drive the feed roller for rotation by the feed roller gear until the leading edge of the sheet arrives at the nipping line of the conveyor roller. Thereafter the feed roller shaft is uncoupled from the feed roller gear so that the feed roller is rotated through the sheet by the conveyor roller after the leading edge has arrived at the nipping line of the conveyor roller. The feed roller gear and the feed roller shaft are again coupled in a fixed time after the trailing edge of the sheet has left the feed roller.

摘要： A color copier includes an exposure light source for exposing an original document with red, blue, and green light, on a photosensitive film having a substrate and an ink coating which includes ink particles of multiple colors carried on the substrate, and on which a reproduction of the original document is formed, in response to the light exposure, through a reaction of ink particles of the color which corresponds to the wavelength of the light reflected from the original document. The color copier further includes a lightproof film case for storing the photosensitive film, an image forming lens for forming an image of the original document on the photosensitive film by focusing the reflected light; a copy paper feeder for feeding a copy paper; a fixer for fixing the image formed on the photosensitive film on the copy paper; and a separation claw which separates the photosensitive film from the copy paper after the fixing of the image.

摘要： A color image reproduction device such as a color copier includes a single light source surrounded by a cylindrical unistructural filter with red, green and blue sections such that red, green and blue beams of light are sequentially transmitted to a colored document as the filter is rotated around the source. Reflected color beams are sequentially made incident on a photosensitive film coated with yellow, magenta and cyanic ink particles which harden by exposure to red, green and blue beams of light, respectively, such that a colored image can be formed by a single scan of the document.

摘要： A color image copier operable both in analog and digital modes has a light source having a lamp and a screen with an opening. The screen is rotatable around the lamp so that light emitted from the lamp can be directed selectively to a color original or to a photosensitive film. Light reflected from the color original is received by an image reader which reads image data from the reflected light. The shutter transmits or screen light from the lamp selectively according to data read by this image reader.

摘要： An intermittent drive mechanism includes, a continuously rotating driving gear; a subsordinately driven gear disposed in a position close to the driving gear, an epicyclic gear being held in such a manner that it can be engaged with the driving gear by its own rotation along the periphery of the driven gear which remains engaged with the epicyclic gear, and a shifting plate that causes the epicyclic gear to be either engaged with the driving gear or disengaged from it by its movement. In response to movement of the shifting plate, when the epicyclic gear is engaged with the driving gear, the rotation force of the driving gear is transmitted to the subordinately driven gear via the epicyclic gear, whereas the transmission of the rotation force is discontinued when the epicyclic gear is disengaged from the driving gear, and, as a result, the subordinately driven gear is intermittently driven.
